Definitions

  • the invention relates to a system and method for provision of insulating cladding for use in conjunction with the wall, ceiling or the like of a building or the like to reduce the three modes of heat transfer across building envelopes.
  • the invention further provides a system and method with a capability of reducing sound transmission, whilst also incorporating the prevention of damp and the elevation of condensation.
  • the invention in particular relates to the provision of prefabricated cladding units to be fixed directly to a wall, ceiling or the like to comprise such a system or in accordance with such a method.
  • a cladding system should reduce the effects of the three principal modes of heat transfer in relation to buildings. These are convection, conduction and radiation.
  • any cladding system or method provides for easy application of the cladding to a wall, ceiling or the like, in particular in such manner as to allow for the easy application of a subsequent finishing coat such as plaster or render.
  • a number of cladding systems are in existence which are effective for reducing in particular convection and conduction.
  • the simplest form of barrier comprises parallel panels defining a gap between. These act to limit airflow, and limit conduction losses. Both the panels and the gap may also serve as an insulator to reduce conduction losses, with the panels being fabricated from thermally insulating material, and the air gap also serving as an insulating barrier. Multiple layers of panels may be provided. Such systems may be prefabricated. Examples include that described in US patent number 3501878. Although an air gap provides reasonable conduction insulation, such a system may further include insulating material, such as is exemplified by UK published patent application 2345071.
  • Such conventional systems can be effective in reducing heat transfer through conduction and convection, but are of limited effectiveness in reducing heat transfer through radiation. Accordingly, as heat transfer through radiation has become more of an issue, such systems have come to be used in conjunction with radiation barriers.
  • the simplest form of radiation barrier is a reflective surface such as for example a metal foil sheet. This might be applied under a plaster/render baseboard or other wall/ceiling covering, such as one fabricated in accordance with the above principles, as is illustrated in UK published application 2367839. Alternatively, reflective layers may be placed over a surface finish such as a render/plaster material. Such an approach is often preferred for example behind internal radiators and other heaters.
  • an insulating cladding system for a surface such as a wall, ceiling or the like comprising a base membrane adapted to be fixable to the said surface, an outer membrane remotely spaced therefrom by means of spacer elements in the gap thereby defined, an outer surface of which outer membrane comprises a keying surface for immediate application of a surface finish such as a plaster, render or the like, and at least one thermally reflective layer retained in position within the said gap and generally coextensive with the said membranes.
  • the at least one reflective layer is supported within the gap laterally spaced from both the base and the outer membrane by means of the spacer elements.
  • the whole system is conveniently provided assembled as a unit, or as a plurality of modular units for modular application, so as to be readily applied in situ onto a wall, ceiling or the like and provide an insulating cladding with a capacity to reduce all three modes of heat transfer which also presents an immediately plasterable, renderable or otherwise finishable surface.
  • the single unit reduces all three modes of thermal transmission in a simple, quick and effective manner which is not provided by prior art systems. It is quicker, easier and cheaper to provide a finished wall or ceiling or the like incorporating the insulating cladding of the invention and a suitable surface finish than has been possible hitherto.
  • the base membrane preferably comprises a generally planar rigid or semi-rigid sheet (that is, a sheet which exhibits sufficient rigidity for the purpose in use when assembled into the system).
  • the sheet may have thermally insulating properties.
  • the sheet is also preferable substantially impermeable to moisture.
  • the base membrane is adapted to be fixable to the wall, ceiling etc, and for example has provision for mechanical fixings, keying surfaces for the provision of adhesive, or other suitable fixings or combinations.
  • the base membrane is conveniently fabricated from suitable plastics material, for example comprising an optionally reinforced thermoplastic or thermoset polymer.
  • the outer membrane similarly preferably comprises a generally planar rigid or semi-rigid sheet, and is conveniently coextensive with the base membrane.
  • the outer membrane serves as a cover layer for the system, and further serves to present an outermost surface acting as a keying surface for the required surface finish such as plaster, render or the like.
  • the outer membrane may conveniently be fabricated of similar material to the base membrane, and in particular may be of similar plastics material and/or may have similar thermally insulating and/or moisture impermeable properties.
  • the outer membrane may be of monolithic construction, with an outer surface integrally therewith inherently serving as a keying surface for the surface covering, or may alternatively be of a multi-layered construction with at least an innermost structural membrane layer and an outermost keying layer.
  • One or more intermediate membranes comprising similar or dissimilar materials, and in particular comprising further rigid or semi-rigid sheets generally parallel to and coextensive with the base and outer membranes, maybe provided in the gap therebetween.
  • the spacer elements preferably comprise rigid lateral projections extending from an inner surface of one or both of a pair of adjacent membranes to space the membranes and define the gap therebetween.
  • the spacer elements comprise an array of projecting studs fixedly attached to or integrally moulded with the membrane.
  • the spacer elements comprise co-engaging extending projections between adjacent membranes.
  • each membrane comprises a studded plastics sheet of a design which will be generally familiar in relation to known insulating cladding systems, wherein internally facing studs co-operably engage to act as spacer elements.
  • Such materials are especially useful, since the surface relief inherently provided on the external surface in consequence of the integrally moulded studs on the internal surface can give an inherently good keying surface for plaster, render or the like and/or for fixing of a unit to the wall or ceiling.
  • the key to the invention is the provision of one or more reflective layers within the gaps defined by the base and outer membrane, including where applicable any gaps defined by an intermediate membrane with a base or outer membrane or with each other, which serve as the main means of reduction of heat transfer through radiation.
  • a radiation reduction layer within the structure of a cladding system in accordance with the invention, the system is rendered able to prevent all three modes of heat loss, and there is no need for the use of additional radiation preventive materials.
  • each reflective layer is disposed within the gap between the base and outer membrane to lie generally coextensive therewith and be supported by the structure formed by the membranes, for example on the surface of a membrane but, more preferably, spaced therefrom and supported by the spacer elements.
  • a reflective layer is disposed between a pair of adjacent membranes, whether the base and outer membrane, or some combination of those and intermediate membranes where present, wherein the spacer elements comprise mutually engaged projecting studs retaining a reflective film layer in position in the gap thereby defined at the point of engagement of the studs.
  • the reflective layer preferably comprises a reflective sheet, and is for example a sheet of metallic material.
  • the outer membrane presents an outermost surface in use which serves as a key surface for plaster, render or like finish.
  • the outer membrane comprises in combination a rigid or semi-rigid plastic sheet structural layer, and one or more outer layers serving as a plaster or render base.
  • such an outer layer comprises an insulating plaster underlayer, for example comprising a dispersion of insulating particles such as expanded polystyrene spheres in a plaster matrix.
  • Such a surface provides a particularly convenient surface for the application of a top coat plaster finish.
  • a method for the application of thermal insulation, and in particular thermal insulation also serving as acoustic insulation and/or damp or condensation prevention, to building envelopes or the like comprises applying a system as above, for example in the form of modular units, and in particular comprises the steps of
  • a system and method of preventing heat transfer covering the three modes: radiation, conduction and convection, and also reducing sound transmission which in a preferred embodiment makes effective use of already known studded semi-rigid sheet material by incorporating a reflective foil or coating to produce a system which can be directly plastered/rendered, and may for example include insulating plaster/render ready for finishing with a top coat.
  • the number of membranes can be multiplied giving a more effective barrier depending on insulation requirements.
  • the material can be applied internally or externally onto any structure or could be utilised in prefabricated panel processes, and finished as required.
  • a structure 1 is illustrated onto which a cladding 2 in accordance with the invention has been fixed by means of mechanical fixing 5, and to which a finish coat 3, such as a plaster or render top coat, has been applied.
  • a finish coat 3 such as a plaster or render top coat
  • the main structural element of the cladding consists of a studded plastic base sheet 9 provided with projecting studs 10, and a studded plastic top sheet 12 provided with projecting studs 13.
  • the projecting studs 10, 13 engage with each other and act to separate the sheets 9, 12 to define an air gap with a series of air-sealed cells 15. These reduce convection losses in familiar manner, with the air gap also serving as an insulator to limit conduction losses.
  • the air gaps may be filled with material offering greater conduction insulation than air.
  • the particular refinement of the cladding in accordance with the invention is the provision of a reflective/radiant barrier in the form of the metal sheet 11.
  • the metal sheet is held in position between, spaced from, and generally parallel to the parallel sheets 9/12 by means of the co-operating studs 10/13. It forms an effective barrier to radiant heat loss, creating a heat flow direction generally in the direction of the arrow H.
  • the cladding thus, in a single integral construction, provides for limitation of all three principal modes of heat transfer.
  • the cladding is further refined, and its effects further enhanced, by incorporation of a low-density layer 17.
  • This low density layer is conveniently in the form of an insulating plaster, for example comprising polystyrene spheres in a plaster matrix, with the back portions 16 of the studs 13 on the outer sheet 12 providing a key to ensure that this plaster under layer is soundly retained as part of the cladding 2.
  • the plaster under layer itself serves as a key for the top coat 3.
  • the insulating cladding of the invention thus provides a means for reducing all three modes of heat transfer in a single application, and at the same time providing a cladding which is immediately ready for application of a finish in situ.
