Description

introduction

The present invention provides an acoustic or thermal multilayer film material, in particular a multilayer sound or heat insulating film material, which is suitable for use on heating, ventilation, air conditioning ducts and shafts.

It is well known that units with high noise emissions or noisy environments need to be insulated to restrict the noise around them. Typical examples include spaces with machines or ducts or shafts that pass through living spaces or work spaces. The purpose of insulation is to restrict the transmission of sound waves to the outside environment. For this purpose, a wide range of insulating materials is provided commercially, which can be fixed in position fixed around the sound-emitting units, lines or rooms. Typically, the insulating material is a multi-layered laminate containing rock wool or equivalent to provide the sound-damping effect. Such laminate panels are secured with wire mesh, tape fasteners and associated fasteners, such as dowels and screws. This type of product is well known and has a number of limitations. The principal limitations are that the acoustic panels are large, heavy, difficult to handle and not easy to install.

Positional mounting requires skill, and since performance is reduced if the panels are not properly secured, the ability to easily correct the insulation at the final inspection of the work would be highly desirable.

The requirement of thermal insulation is also a widespread requirement to reduce the heat flow while limiting the requirements for heating or cooling by the insulation between environments which are separated by the insulation. The commercial solutions are numerous and the building regulations often require a certain level of thermal insulation, such as in new buildings.

While sound insulation is available in many forms, there is a continuing need to provide such insulation with a broader spectrum of sound reduction, with lower weight and more convenient mounting. In particular, although sound insulation for a particular application may be tailored to general building applications, it is preferable for sound insulation to operate over a wide range of wavelengths, and this is not achieved too often.

Another aspect of the insulating material is its use as barriers to fires by providing flame retardancy. This generally entails a different set of requirements than those for thermal insulation and sound insulation. In particular, a balance is needed between providing a low flammable product mass and a higher mass for absorbing sound.

The above-mentioned problems of insulation to reduce the transmission of sound, heat and fire are well known and for the construction of buildings and the associated services, a wide range of different insulating materials have been provided, depending on the particular balance of the required properties.

In the present case, there is a particular need for improved insulation for use in a riser of a building. A riser is a vertical well through a portion of the building, such as from top to bottom in the building, which serves the purpose of carrying, for example, gas, water, electricity and the drainage downcomer. A drainage downpipe is a large diameter pipe used to channel sewage from a building. The insulation for use in this situation accommodates a number of requirements, where thermal insulation is important to stop condensation such as from warm building air on cold, incoming supply lines for, for example, water or gas. It is also important that it provides protection against water so that if leakage occurs, such as in a water inlet or in a drainpipe, the electrical wiring is protected or at least no water from the insulation on the water pipe to the outside occurs. Low gas permeability is also useful to channel any slight gas leakage along the length of the pipeline to where it can leave a structure, this is also relevant to a drainage downcomer where minor leakage will result in undesirable odors.

In addition, insulation should be easy to apply for use in a specific environment, risers are usually kept to a minimum size because they do not provide usable space in the buildings for the occupants and the installation of leads side by side by various traders, such as installers and Electrician, means that the insulation must be retrofitted over all supply lines in a confined space.

Another problem is that the insulation must be so robust that it is not easily broken or torn during installation or removal and reassembly, as is required, for example, during maintenance. Typical metal foils tear easily and adhesive compositions have a relatively high adhesive strength. Accordingly, there is a need for a mechanically robust insulating material.

Similarly, ongoing repair may require the insulation to be easily removed and reattached.

Accordingly, there is a need for a form of insulation that provides a beneficial combination of features such as low profile, flexible, lightweight, easy to use, and easy to remove and reattach. Depending on the application, the material should provide a combination of sound, heat, water and gas-inhibiting properties with consistent fire resistance properties.

One problem frequently encountered when using self-adhesive materials is that improper positioning or imperfection can result in unsightly bumps and wrinkles that may result in less effective insulation in the case of self-adhesive insulation. Accordingly, it is desirable to provide a self-adhesive material that can be peeled off without damage and adjusted prior to re-application. This would limit the waste that results from disposing of material that has been removed and contributing to the material's effectiveness by supporting its correct application.

Although some forms of isolation may be excellent in certain aspects, there is still a need for an improved and certainly alternative form of isolation with a broad spectrum of effectiveness in view of the above reasons. The physical robustness of the insulation is also important.

One form of material that has been widely used in packaging but has also found use in insulation is known as 'bubble wrap', which material comprises a plastic film on which evenly elevated cells having a flat cylindrical shape are distributed. to contain the air. The raised cells are arranged in a regular pattern of a given dimension and are spaced from each other.

Physical isolation structures relevant to the present invention have been disclosed. The US 2014/0199537 discloses a foam material having an adhesive side and an aluminum foil cover. The present invention represents optimizations of this general technology especially for use in the construction industry JPH09210291 discloses a conduit with integrated insulation which incorporates bladder layer isolation to restrict heat transfer and the like JPH0989357 discloses a material for forming manholes, which also has a bladder layer for sound insulation purposes. The DE2307559 discloses an adhesive tape which includes insulation, but this is designed to be wound around the leads, and is cumbersome to use and proper installation. The US 8343614 describes a reflective insulation material from a metallized polymer film which is directed to the isolation of packaging, vehicles or from a building, but no particular attention is paid to any installation problem. The FR 2011059895 describes a removable sound insulation for floors using natural felt fibers to provide sound suppression.

Another problem that occurs is that the insulation applied to piping or shafts during installation is broken or damaged during maintenance or general wear becomes. Exchanging the insulation can be a skilled operation and at least time consuming and uncomfortable unless it is replaced immediately by the personnel during maintenance. This means that areas that were originally insulated with high quality will gradually become less well insulated over time, unless the insulation can be reapplied or adjusted fast enough to be easily replaced.

Accordingly, there is a need, as addressed by the present invention, to provide lightweight, easy-to-install acoustic or thermal insulation that meets the same performance criteria as existing products in terms of the aforementioned properties, but with a wide range of insulation properties that are readily available a better positioning can be removed, which can be reapplied after a period of time or allows access to the isolated area. In addition, although providing effective insulation properties, the material is preferably also mechanically robust in both tensile strength and resistance to cracking during bending.

• a) a cover layer glued by
• b) an adhesive covering layer ( 4 ), which comprises an adhesive film, for;

• e) a peelable protective release paper or release film ( 6 ) which is peeled off in use to expose the pressure-sensitive adhesive side approximately for bonding to an area to be insulated.

Solid foam (characteristic c)

A solid foam is made by generating gas bubbles in a liquid which is subsequently solidified to entrap the gas within the cells. Solid in this sense means solid as opposed to liquid or gas and not rigid. The foam is preferably flexible, such as provided by foamed polyethylene.

Closed-cell foam

A closed-cell foam is a foam in which there is no communication between the cells. In a closed-cell foam, the gas forms discrete pockets, each of which is completely enclosed by the solid material. A closed-cell foam is preferred for thermal insulation as it provides a barrier to convection. Closed cells also provide benefits where leakage can occur because any fluid does not spread through the solid foam layer, as may occur in fiber insulation.

Polydisperse size distribution

The solid foam layer of the invention may comprise cells having a polydisperse size distribution, i. they are of a variety of different sizes. Reducing the propagation of a wide range of sound requires limiting the transmission of both long and short sound waves. The polydisperse size distribution of cells provides cells of smaller and larger dimensions; Small cells are beneficial for thermal insulation, while soundproofing benefits from larger cell sizes. The presence of a polydisperse size distribution in the solid foam layer is a practical way to provide both smaller and larger cells in a single layer. Such foams are preferably formed by extrusion in a single operation.

The solid foam layer, such as prepared by extrusion of air entrained in a polymer, preferably comprises cells commonly described as irregular polyhedra. Such cells have a minimal wall material and are thus lighter. The preferred cells of the present invention are elongate, such as elongated polyhedra, as this provides two dimensions with a wider spectrum for acoustic inhibition. The dimensions can be determined by cutting a cross-section through the foam and measuring the dimensions exposed thereby. For the purposes of the present invention, the dimensions of such cells are determined by measurement along an arbitrarily placed cross-section (such as obtained by cutting the material with a sharp knife) and in the plane of that cross-section. For reasons of consistency, the cut should be made for the cross section perpendicular to the plane of the cover layers. A 20 × binocular microscope with a crosshair is used. 90% means 90% based on the number of 100 adjacent cells.

The cells may be partially elongated when elongated, 90% of the elongated cells of the present invention may have a longest dimension of 1.5 to 3 times the shortest dimension as measured for the longest dimension previously. 90% of the cells of the solid foam layer may have a longest dimension of 0.01 to 5 mm, preferably 90% of the cells of the solid foam layer have a longest dimension of 0.5 to 3 mm. For multilayered solid foam embodiments (such as 4 and 5, below), the solid foam layer has a longest dimension of 0.5 to 2.5 mm.

These dimensions are preferred because convective heat transfer within the cells is limited, and heat transfer by conduction is limited by the heat transfer properties of the gas within the cells.

The solid foam layer of the invention may vary in thickness between 2 and 10 mm, and more preferably between 3 mm and 5 mm, which gives a good balance of performance with respect to the thickness of the material, i. h., its mass in relation to its weight. In some embodiments, more than one solid foam layer may be multiple layers, preferably two layers. In fact, it has been found that acoustic performance improves with the additional layers of solid foam having the same overall thickness, rather than a single layer of thicker foam.

thermoplastic

The thermoplastic of the solid foam layer is preferably polyethylene. The thermoplastic may include one or more fire retardant additives.

The thermoplastic is ductile, which means that the material can be processed manually at 25 ° C without cracking, breaking or permanent bending during use. This property may simply be one which is inherently derivable from a polyolefin such as polyethylene.

Gases in solid foam

The gas trapped in the cells of the closed cell foam may preferably be air which has good thermal insulating performance and which can be easily incorporated into the cells. The gas may more preferably be nitrogen or argon, so as to improve both the thermal insulation and avoid the provision of oxygen for the ignition. The gas may be one or more of FE-13, 1,1,1,2,3,3,3-heptafluoropropane, FE-25, haloalkanes, bromotrifluoromethane, trifluoroiodomethane, NAF P-IV, NAF S-III, NAF S 125 , NAF S 227 and triiodide (trifluoroiodomethane) to provide flame suppression.

Multi-layered construction

The multilayer construction of the film material provides particular noise reduction benefits: the reflective film layer, the adhesive cover layer, the solid foam layer, and the adhesive side layer combine to limit sound transmission and reverberation. Any change in material means that the sound has to cross borders, which attenuates the sound transmission. The solid foam provides several such limits. Sound insulators reduce the transmission of sound, while sound absorbers reduce reverberation.

Several foam layers

The solid foam may be present as a single layer or multiple, preferably 2, laminated closed cell foam layers bonded together on a common side (rather than edge). This provides a further limitation and improved sound reduction.

film material

The novel features of the sheeting of the present invention provide an insulation material that can be handled easily, such as having a density of less than 250 kg / m ³ (low weight compared to current products) for a product that is 5 mm thick is (low mass for the level of insulation achieved) and a sound (especially sound with wide bandwidth) and thermal insulation together with a heavy flammability provides, and the film material must also be understood that it is lighter, with lower density and thinner than existing products in providing an equivalent set of properties. Another advantage is that it is sufficiently flexible to cover small bumps or to fit around corners, and the weight of a typical 10 meter long roll is within the manual handling handle length requirements, which is often required in the art Installation of insulation in buildings, eg. B. in shafts and cavities.

Adhesive-side layer, pressure-sensitive adhesive (feature d)

The adhesive-side layer is a layer of pressure-sensitive adhesive which adheres to one side of the solid foam layer and the other side of which is a pressure-sensitive adhesive side with which the film material adheres to the object to be insulated.

In the present invention, the adhesive side layer may be a relatively thick viscoelastic layer, such as a butyl adhesive, or it may be a relatively thin adhesive film, such as an acrylic adhesive.

The material has a pressure-sensitive adhesive side, as a result, no additional fasteners are needed for the installation, which is advantageous because fasteners can act as thermal bridges, reducing thermal efficiency or providing ways to transmit sound.

Pressure sensitive adhesives are characterized by three properties: tackiness, which is the ability to bond directly under light pressure, peel strength, which is the ability to resist separation from a surface, and shear strength is the ability to resist internal cohesive failure under shear.

adhesive type

The adhesive side layer may be a viscoelastic layer (see, for example, Embodiments 1, 2 and 4) whose viscoelastic properties also improve the acoustic performance of the material. A viscoelastic material is one which has both viscous and elastic properties when undergoing deformation. The adhesive side layer may be a butyl polymer; this is typically provided as a thick 'putty' like layer and is good for adhesion to irregular surfaces, but it can reduce the characteristics of flame retardancy. Advantageously, the adhesives may be hydrophilic adhesives for attachment to plasterboard or a hydrophobic adhesive for attachment to a polyethylene pipe: two common applications in building insulation. In embodiments in which the adhesive side layer is a viscoelastic layer, its thickness varies between 0.1 and 1.5 mm, and most preferably between 0.4 and 0.6 mm. Such a thick viscoelastic layer has the advantage of bonding to uneven surfaces and the adhesive mass of this layer may deform overall to correspond to contours in this thickness range, for example 0.1 to 1.5 mm, as a result, a 0.4 to 0.6 mm thick layer preferred. A very thick layer can reduce the properties of heavy flammability. In embodiments in which the adhesive side layer is a viscoelastic layer, the viscoelastic layer may be a redetachable adhesive.

In other embodiments (eg, 3 and 5), the adhesive side layer may be an adhesive film. The adhesive film of the adhesive side layer may have a thickness of between 0.01 and 0.2 mm, most preferably between 0.02 and 0.06 mm. In these embodiments, the coating weight of the adhesive sheet is between 10 and 200 g / m ² and is preferably between 20 and 50 g / m ² . Preferably, the adhesive sheet is a water-based acrylic adhesive or a hot melt adhesive resin. An adhesive sheet has advantages in that it reduces the weight of the product and improves the fire resistance performance, and is more preferable when it is to be glued to smoother surfaces. In particular, the variability between measurements performed in fire resistance tests is reduced, resulting in a more consistent fire resistant property.

In embodiments where the adhesive side layer is an adhesive film, the adhesive film may be a redetachable adhesive. Because the application is important, it may be useful for the user to be able to apply the material and then remove it again and reposition it easily without damaging the material, which would cause waste. The redetachable adhesive also allows the insulation to be removed and reapplied, for example, at a later time during service operations.

Pressure sensitive adhesives are characterized by three properties: tackiness, which is the ability to bond directly under light pressure, peel strength, which is the ability to resist separation from a surface, and shear strength is the ability to resist internal cohesive failure under shear. Repositionable adhesives have low peel strength to allow the material to peel off and stable stickiness over time. The redetachable adhesive is preferably an acrylate copolymer with a suspension of microspheres. The composition may comprise: from 88 to 99 percent by weight of at least one unsaturated vinyl monomer selected from non-tertiary alkyl acrylates; 0.2 to 5 weight percent of at least one emulsifier monomer and 0 to 10 weight parts of at least one zwitterionic monomer. The U.S. Patent 3,921,464 describes a redetachable adhesive and other redetachable adhesives are well known to those skilled in the art and are readily available.

The adhesive side layer may have a peel strength at 180 ° with a maximum of 225 g or more preferably of 30 g. The adhesive may have an initial adhesion after a residence time of 1 second of up to 350 g and more preferably in the range of 350 g to 90 g.

A redetachable adhesive-side layer has the following properties when tested on # 304 stainless steel with # 3 surface finish: peel strength at 180 ° with a maximum of 225g and initial adhesion after a 1 second residence time of up to 350g: and after 1 day residence a peel strength at 180 ° with a maximum of 250 g and an initial adhesion of up to 400 g. These parameters have been found to define a material that is redetachable in the conventional sense of the word in this technical field.

More preferably, the redetachable adhesive-side layer has the following properties when tested on # 304 stainless steel having a # 3 finish: peel strength at 180 ° with a maximum of 20 to 40 g and initial adhesion after a residence time of 1 second from 80 to 100 g: and after 1 day residence time a peel strength at 180 ° with a maximum of 20 to 50 g and an initial adhesion of up to 150 g. These properties provide the insulating material with excellent redetachability properties such that a worker realistically insulates to return after a period of time (in the measurement after one day, but in practice the adhesion rarely changes after a number of minutes of adhesion) and detach a 1 m ² web without the use of excessive force or tearing of the material (such as the Test 1 material described below).

The above measurements refer to the harmonized International Standard for Peel Adhesion of Pressure-Sensitive Adhesive Tape; Method A; as it is for example in http://www.pstc.org/files/public/101.pdf can be found.

One skilled in the art can obtain suitable adhesives by specifying the above parameters and the leads to which the adhesion is to take place, as this chemical base is well established for this technology.

Adhering topcoat (feature b)

In the present invention, the adhesive cover layer ( 4 ) may be a viscoelastic layer (as previously described, but with a higher peel strength, if it is even peelable). An adhesive sheet may also be present as the adhesive side layer. The adhesive cover layer is preferably connected irreversibly.

The type of adhesive will generally be selected by those skilled in the art depending on the specific surfaces to be bonded, and the preferred compositions are provided herein. The weight of the adhesive sheet per unit area is also provided.

The adhesive film according to the previous criteria can be provided in various ways:
for the adhesive cover layer, this is preferably provided by means of a prefabricated aluminum foil adhesive tape in which the adhesive film is already attached to the aluminum foil. Techniques for providing such films and such films are known in the industry and can be made, for example, by spraying or extruding an adhesive onto an aluminum foil. Such a prefabricated aluminum foil may then be added to the solid closed foam layer during the manufacture of the multilayered sheeting material of the present invention by contacting the mold and the foil under pressure. This provides a quick and easy way of forming part of the structure of the material of the present invention. With respect to the final product, this has the advantage that irregularities in the solid foam made from a variety of blisters are masked and counterbalanced by the preformed aluminum foil adhesive tape when the relatively stiff (e.g. Adhesion against the solid foam is forced so that the solid foam transforms to form a more uniform surface, which is better suited to present a flatter contact surface with a high contact area, so that when the material is repositioned during use and in particular, if the two adhesive layers are of the same material, then the adhesive layer that will always give first will be the adhesive side layer because it will have the smaller contact area. In other words, the potential delamination of the material is reduced in use.

An adhesive sheet, which is present as the adhesive side layer, is preferably provided in the form of a carrier sheet (eg, 5 to 50 μm thick) such as polyethylene, to which an adhesive is sprayed or extruded on both sides. This double-sided adhesive tape is then provided with the peelable protective layer and also adhered to the solid foam, this has the advantage that irregularities in the solid foam, which is made of a plurality of bubbles, covered by the support film and compensated to a certain extent in that the backing sheet is pressed against the solid foam during adhesion such that the solid foam transforms to form a more uniform surface which is more suitable for presenting a flat adhesive side layer for subsequent adhesion during use provides a more consistent adhesion to surfaces to which the material is applied.

Weight and thickness of the adhesive covering layer (characteristic b)

The adhesive cover layer may be a viscoelastic layer whose viscoelastic properties also improve the acoustic performance of the material. A viscoelastic material is one which has both viscous and elastic properties when undergoing deformation. The adhesive side layer may be a butyl polymer; this is typically provided as a thick 'putty' like layer and is good for adhesion to irregular surfaces, but it can reduce the characteristics of flame retardancy. Advantageously, the adhesives may be hydrophilic adhesives for attachment to plasterboard or a hydrophobic adhesive for attachment to a polyethylene pipe: two common applications in building insulation. In embodiments in which the adhesive side layer is a viscoelastic layer, its thickness varies between 0.1 and 1.5 mm, and most preferably between 0.4 and 0.6 mm. Such a thick viscoelastic layer has the advantage of bonding to uneven surfaces and the adhesive mass of this layer may deform overall to correspond to contours in this thickness range, for example 0.1 to 1.5 mm, as a result, a 0.4 to 0.6 mm thick layer preferred. A very thick layer can reduce the properties of heavy flammability.

Alternatively, an adhesive cover layer consisting of an adhesive film disposed between the cover layer (such as the metal foil) and the solid foam layer provides the adhesion of the cover layer to the solid foam layer. The adhesive film has a thickness of between 0.01 and 0.2 mm and is most preferably between 0.02 and 0.06 mm. The coating weight of the adhesive film is between 10 and 200 g / m ² and is preferably between 20 and 50 g / m ² . Preferably, the adhesive sheet is a water-based acrylic adhesive or a hot melt adhesive resin. The adhesive film provides the adhesion between the cover layer and the solid foam layer, but has a low weight and improved flame retardant properties. It is believed that additional voids provided between the film and the solid foam layer also contribute to the thermal and acoustic properties of the multilayer film material.

Additional adhesive films may also be present between the first solid foam layer and the second solid foam layer and other solid foam layers. If present, additional adhesive sheets have a thickness between 0.01 and 0.2 mm, and preferably between 0.02 and 0.06 mm. The coating weight of the additional adhesive film is between 10 and 200 g / m ² and is preferably between 20 and 50 g / m ² . Preferably, the adhesive sheets are a water-based acrylic adhesive or a hot melt adhesive resin. Preferably, further adhesive films have the same properties as the adhesive film of the adhesive cover layer to facilitate manufacture.

Covering layer (characteristic a)

The cover layer is an outer layer when the film material has been adhered to an object to be insulated. The cover layer has a thickness of between 10 and 500 μm. The cover layer may be a layer of metal foil, such as aluminum, in which case the foil may have a thickness between 50 and 200 μm. The cover layer may be a protective cover layer. The topcoat may be selected to have particularly desirable, such as protective, construction properties, such as: high flammability, heat reflection (preferably having a lustrous metallic finish), chemical resistance, or water resistance to meet those specifications for the To incorporate the design without the need for an additional product. A metal foil layer is particularly advantageous because it lowers the transfer of heat by reducing the emissivity of the material when provided with an outer glossy, reflective metal finish, and also has poorly flammable properties. The metal foil layer may be a laminate construction. Such a laminate may comprise a polyester on the surface which is adhered to the solid foam layer. The polyester layer may preferably be polyethylene terephthalate. The metal foil may have a lacquer on its outer surface. The lacquer may preferably be a nitrocellulose lacquer. The metal foil may combine a painted surface and a polyester layer. The laminate construction of the film provides a tensile strength to the film of the cover layer and allows for effective bonding to the next layer. The painted surface prevents galvanic corrosion if the aluminum layer should be in contact with another metal. A combination of the two coatings advantageously provides improved tear strength.

Peelable protective release paper or release film (feature e)

To protect the adhesive side, a peelable protective release paper or polymer film is included as an additional layer disposed on the adhesive side of the adhesive layer. The release paper or release liner may be a polypropylene film. The release paper or release film may be surface treated, preferably with a silicone release agent and most preferably with a methyl silicone release agent. This layer allows the user to expose the adhesive side of the product in use immediately prior to installation, which is convenient, and the adhesive layer will adhere in-situ when needed.

Advantages of the roll form

To facilitate handling and use, the sheet material may be supplied in roll form. This has the advantage that large quantities of the material can be delivered while remaining easy to store and handle. The roll is preferably presented such that the peelable protective release paper or liner is on the outside of the roll, which facilitates use by allowing the insulating material to be applied as the material progressively rolls. This is especially so for the present invention, as not by placing the stretchable metal foil on the inside, the side that is stretched, the adhesive side, and when it is rolled out onto a flat surface, or even even a curved surface, such as a tubing or hose, this provides a larger adhesive surface area Better adhesion, particularly when using an adhesive film, and an adhesive film that is stretched completely flat is not necessarily an optimal bonding surface when presented to rough surfaces such as found in building constructions. As part of this preferred roll form, the release film has a crepe-like structure. This structure allows rolling with the adhesive side out without splitting the film or wrinkling the aluminum foil.

Kit

Another aspect of this invention is an insulation kit comprising parts comprising the multilayer material bonded to similar materials in the form of adhesive tape for securing the edges and covering any gaps.

Additional cover layer

Another type of layer that can be incorporated allows acrylic paint to be applied directly to the surface at locations for which it is desirable to have a finish that matches the existing decor. This addresses the problem of existing insulation that does not allow the use of water-based paints. Such a layer is the outermost layer in each laminate and is the outermost layer of the entire sheet material.

The layer may consist of the aforementioned polyester construction which is modified to increase the hydrophilicity; this has a contact angle with water at 25 ° C between 10 and 80 °.

The invention also includes a method of isolating an object by cutting the sheet material described herein to size and applying it lightly to the object.

SPECIAL DESCRIPTION

Embodiments of the present invention will now be described with reference to the drawings, in which:

1 a cross section of the material of embodiment 1 and embodiment 2 represents

2 a cross section of the material of embodiment 3 and embodiment 4 represents

3 represents a role of the material as it is delivered to a construction site.

Embodiment 1

This embodiment of the multilayer film material comprises a cover layer ( 1 ), which in the exemplary embodiment is an aluminum foil selected for its heat-reflecting properties. The thickness of the aluminum foil is 50 μm and this thickness contributes to the sound-damping properties of the material. The aluminum foil itself is a laminate construction which has a nitrocellulose-based lacquer on the outer surface and a polyethylene surface on the back. This aluminum foil layer ( 1 ) is attached to an adhesive polymer overlay, a viscoelastic butyl polymer ( 4 ) attached to the first surface of a solid foam layer ( 2 ) is glued. The solid foam layer consists of polydisperse irregular polyhedron cells ( 3 ) containing air; whereby the cell walls ( 3 ) are formed of polyethylene. The cells are continuously distributed through the solid foam layer; the cells have an average size between 1 and 4 mm, preferably between 2 and 2.5 mm. For irregularly shaped cells, the size is the maximum dimension. In this embodiment, the thickness of the solid foam layer is approximately 3 mm.

The second surface of the solid foam layer ( 2 ) is adhered to a viscoelastic layer of butyl polymer and then to an adhesive side layer containing a pressure-sensitive adhesive side ( 5 ), which in this embodiment is a redetachable adhesive of a type well known in the art of pressure-sensitive adhesives.

Another layer on the surface of the adhesive side layer ( 5 ) is a release film ( 6 ) of a type which is well known in the field of pressure-sensitive adhesives, allowing the release film ( 6 ) can be easily peeled off to remove the adhesive-side layer ( 5 ) immediately before installation. The release film ( 6 ) is made of polypropylene and has been treated with a silicone release agent, it has a crepe structure.

The material can be supplied in rolls, as in 2 are illustrated, which is convenient for handling purposes. The rolls are presented such that the peelable film is on the outside of the roll to facilitate the application of the material. For the embodiment described above, with a roll of 10 m length and 1 m width and having a thickness of 5 mm, the weight of a roll is typically 18 kg, a weight which is in the low risk area of a manual risk assessment Handling of carrying and lifting loads based on lifting twice an hour (as determined by the Publication INDG383 06/14 defined by the British Government). In addition, it is the low weight of the multilayer material that makes it possible to attach it using a conventional releasable pressure-sensitive adhesive as described in the previous embodiment, which provides significant advantages in terms of ease of use.

The person using the material cuts off the required size of the required material from the roll. The release paper ( 6 ) is removed from the material at the upper edge of the material to be installed and the adhesive side ( 5 ) is facing the wall to be insulated or the shaft to be insulated. When the top edge is firmly in place, the remaining release paper ( 6 ) and the whole plate is smoothed and fixed firmly to the wall or the shaft. If the quality of the application is considered insufficient, the material can be peeled off and reapplied.

Similar panels are cut and glued side by side to cover the entire area as needed, and an adhesive tape is used to secure the joints. The adhesive tape of the same design as the present invention can be used, which has the advantage of keeping the acoustic or thermal properties upright, should any gaps remain in the installation phase, or it can be used for small tricky areas, more conveniently may be to use a tape with a width of 5 to 10 cm.
