System for control and / or remediation and / or treatment of thermal insulation systems in building industry

Technical field

The technical solution relates to a system for the control and / or rehabilitation and / or treatment of thermal insulation systems in the building industry. Insulating systems, contact or non-contact, represent a construction product installed on the building structure. Air gaps and / or air cavities are situated between the building structure and the building insulation.

BACKGROUND OF THE INVENTION

Contact thermal insulation systems in the construction industry include a thin outer reinforced layer, such as a plaster that is insulated. Under the insulator there is an adhesive layer, which should be at least 40% of the area, and mechanical PE (polyethylene) dowels, or other mechanical or chemical anchoring elements. The contact system is bound to European standards, based on ETAG 004, 014, according to which the adhesive layer is formed by a circumferential continuous band that closes the air gaps, cavities. These air gaps, cavities, are created separately, between each insulating plate and the facing structure, in an area of not more than 60% of the insulator area.

The adhesive layer and anchoring of the insulation layer become the most risky place in contact thermal insulation systems. Without destructive methods, it is uncontrollable and irreparable. The low cohesive adhesive layer degrades a significant proportion of the insulation of contact systems (eg ETICS) by reducing their service life. It threatens residents and passers-by citizens with the unexpected destruction of the entire formation. This is increasingly apparent mainly in prefabricated houses. The dilapidated surfaces of such houses have been and are insulated without adequate remediation and their amortization continues under such insulation. Moisture of the adhesive layer due to condensation or leakage then releases the locally dilapidated render with the adhesive.

Most of the contact systems used for thermal insulation of houses by their technical solution do not allow the observation of certified technologies of contact thermal insulation systems (eg ETICS), neither continuous checking of adhesion of insulation layers on the building structure nor remediation of possible defects in this layer. As it is a permanently created sandwich that falls within the field of construction products, its quality and functionality should be tested after its installation. None of the previously known technologies is able to detect and repair the condition under the insulator without destructive methods. Inspection is usually carried out locally, or at a time when the defect can only be detected visually on the surface, or when the entire structure has become molded and possibly wet. However, this is usually too late for any remedial action. If the insulation system itself destroys, it threatens the health and lives of citizens. In case the anchoring and adhesive system was only partially disrupted and the destruction did not occur, it is almost certain that the functional life of the entire thermal insulation is endangered. In doing so, the risk of sudden destruction gradually increases. The lack of a reliable control of the adhesion of the adhesive layer does not even allow for additional remediation. Contact thermal insulation systems require separate bonding with pre-applied adhesive to the back of the insulator and separate mechanical anchoring from the face of the insulator.

There are many anchors on the market mainly used in construction. These are PE (polyethylene) dowels, metal spacers, chemical anchors and net spacers. The anchoring types used from the outside are linked to climatic conditions, such as temperature, which is decisive for the anchoring quality. At low temperatures, the physical properties of the individual components of the building system, such as insulation, anchor, wood, substructure, wall, etc., change. Due to these influences the PE anchors lose mechanical strength. Metal dowels dilate and chemical reactions do not result in a full chemical reaction. All of them then create disadvantageous thermal bridges across the insulation stack. Another negative effect is the incoherence of the substrate, such as unevenness and humidity of walls and insulated building structures in general. Their use is therefore completely unsuitable on dilapidated surfaces. It acts only by a point mechanical ground

By compressing the individual layers, which does not correspond to the cohesive strength of the insulator. Therefore, there is no need to transfer the holding force to the substrate.

The net spacers are dependent on the PUR (polyurethane foam) used, which in the winter period expands longer and reaches the appropriate volume over a longer period, thus prolonging the anchoring operation. In general, anchoring work is not recommended at low temperatures as it may be hazardous. Temperatures above + 5 ° C are indicated as a safe outdoor temperature limit at which insulators can be mounted without danger and risk. At lower temperatures, or at temperatures around or below freezing, there may be icing or ice in the substrate, which changes the properties and shape of the anchorage point after thawing. Among other things, especially with ETICS, an unfavorable humidity climate is created under the insulator, without sufficient water evaporation.

As far as we know, there is currently no way of checking, measuring and diagnosing the condition of thermal insulation systems, whether contact or non-contact, in the adhesive and anchoring layer, which is the most risky point of any thermal insulation system. There are only repair methods for contact thermal insulation systems, which are destructive and usually irreversibly damage part or even the entire thermal insulation system. Remediation or modification is also not carried out on such systems because the defects cannot be detected in time. For non-contact systems in adhesive and anchoring layers, remediation is not necessary due to the high adhesion of the anchoring system used.

The essence of the technical solution

These disadvantages will be eliminated or substantially reduced by a system for the control and / or remediation and / or treatment of thermal insulation systems in the building industry, where the thermal insulation systems, contact or contactless, are a building product installed on the building structure and air gaps are situated between the building structure and building insulation; and / or air cavities. The essence of the present invention consists in providing at least one measuring probe for the inspection, measurement and diagnosis of thermal insulation systems and / or at least one steam nozzle for the rehabilitation and / or treatment of thermal insulation systems in the air gaps and / or air cavities.

It is preferred that each measuring probe and / or steam nozzle is housed in an aperture extending from the outer shell of the building structure at different angles to the horizontal plane and resulting in air gaps and / or air cavities.

It is also preferred that, for the purpose of rehabilitating and / or converting the insulation system into air gaps and / or air cavities, a mass is implanted to form an adhesive layer between the building structure and the building insulation and / or at least one anchoring element between the building structure and building insulation.

Preferably, to form an adhesive layer between the building structure and the building insulation, there is an expansion mass forming adhesive targets.

The anchoring element may be an expansion anchor formed of a spacer and an expansion mass.

For the system of control and / or remediation and / or treatment of thermal insulation systems in the building industry there is used a method of control and / or remediation and / or treatment in thermal insulation systems. This is done by introducing into the air gaps and / or air cavities at least one measuring probe for the control, measurement and diagnosis of thermal insulation systems, and / or at least one steam nozzle for the rehabilitation and / or treatment of thermal insulation systems, and into the air gaps and / or air cavities are implanted by the composition to form an adhesive layer between the building structure and the building insulation and / or at least one anchoring element between the building structure and the building insulation.

To introduce the measuring probe and / or steam nozzle into the air gaps and / or air cavities between the building structure and the building insulation, at least one aperture is guided from the outer shell of the building structure at different angles to the horizontal plane and resulting in air gaps and / or air cavities.

The adhesive layer may be formed by an expansion mass which forms an adhesive target between the building structure and the building insulation.

-2GB 21427 U1

The anchoring element may be formed from the spacer by foaming the expansion mass into an expansion anchor disposed between the building structure and the building insulation.

In the air gaps and / or air cavities, a measuring probe and / or steam nozzle inspects and diagnoses the necessary remediation and / or modification of the thermal insulation system by detecting at least one actual value from the values including air temperature, air humidity, air flow and adhesion adhesion . In the air gaps and / or air cavities, the measuring probe and / or steam nozzle performs measurement, inspection and diagnostics for the necessary remediation or modification of the thermal insulation system at random, occasional, predetermined time intervals or continuously.

In the air gaps and / or air cavities, measurement, inspection and diagnostics can be performed remotely, possibly with recording of measurement data.

Before implanting the mass to form the adhesive layer, the aperture is cleaned and then an expansion mass is introduced to create double-sided adhesive targets in the aperture forming anchoring points in the air gaps or cavities.

Further, prior to implanting the at least one anchoring element, the opening and, optionally, the anchoring element is cleaned at the same time, and then the opening with the inserted anchoring element is latched to create anchoring points in the air gaps and / or cavities between insulation and building structure. .

Prior to implantation of the expansion mass and / or implantation of the at least one anchoring element, the opening and, at the same time, optionally the anchoring element may become warm after cleaning.

Prior to implantation of the expansion mass and / or implantation of the at least one anchoring element, the bore and, optionally, the anchoring element, after cleaning and subsequent heating, are moistened with pressure steam at a temperature of 80 to 140 ° C at a pressure of 1 to 5 bar. .

The expansion mass can be implanted even at low external temperatures, at least from freezing, in the range of 0 to 5 ° C.

The main advantage of this technical solution is that the system of inspection and / or remediation and / or treatment allows these activities to be carried out by a non-destructive method without a major damage to the surface of the building structures. This system is multifunctional because it provides a range of functions, adhesion, distance, dilatation, fixation, detent, thermoinsulation, waterproofing, while ensuring high adhesion in a variety of materials throughout the insulation stack. At present it is the only control applicable in the area of thermal insulation of buildings. The advantage is that it is possible to inspect and rehabilitate the thermal insulation layer as a construction product, which includes air gaps and cavities and adhesive layers in contact with the insulated substrate. Furthermore, air gaps and / or air cavities can be used to control the insulation system and optionally for subsequent remediation and anchoring by implanting adhesive anchors and adhesive targets. The measuring and pressurizing control activity is carried out in the air cavities and gaps, below the insulating stack, so that the actual state can be detected directly in the hazardous existing adhesive layer. Existing entrances, holes or gaps can be used under the insulation, or a hole can be created across the insulation stack. Pressurization can be performed after the measurement. All observable values can be recorded. After the operations have been carried out, the opening can be blinded or further used as a repeat measurement and inspection site, e.g. for the entrance for disinfection of cavities and gaps, as a site for implantation of an adhesive target under the insulation, as a site for forming an anchor with mesh spacer.

In the orifice, the measuring probe and / or the steam nozzle inspects and diagnoses the necessary remediation or modification of the construction product by detecting at least one actual value from the values including air temperature, air humidity, air flow and adhesion adhesion function. This inspection and diagnostics for the necessary remediation or modification of the construction product is performed at random, occasionally, at predetermined time intervals, or continuously. Inspection and diagnostics can be performed remotely or with recording of measurement data. The measuring probe is also a control probe and detects parameters in the air gap or cavity that are

-3GB 21427 U1 for each certified system. The values determined determine whether remediation is necessary at all and, if so, to what extent. The steam nozzle makes it possible to determine the adhesion of the adhesive layer.

Prior to implantation of the expansion mass, the aperture is cleaned and then the expansion mass is introduced to form double-sided adhesive targets in the aperture creating anchoring points in the air gaps or cavities. The expansion adhesive target provides non-mechanical adhesion between the insulation and the building structure.

Prior to implantation of the at least one expansion anchor, the hole and the anchor are cleaned simultaneously, and then the anchor hole is foamed to create anchor points in the air gaps and / or cavities between the insulation and the building structure for the remediation. An expansion anchor, ie a reinforcing anchoring element that creates mechanical and chemical joints between the insulation and the building structure with high adhesion! above 450 N, even up to 1000 N.

Prior to implantation of the expansion mass and / or implantation of the at least one expansion anchor, the aperture and at the same time the anchor is heated after cleaning. This heating can be carried out by various heat sources, eg steam, hot air or hot water, or contact electrically.

Prior to implantation of the expansion mass and / or implantation of the at least one expansion anchor, the aperture and at the same time the anchor, after cleaning and subsequent heating, are moistened with pressure steam at a temperature ranging from 80 to 140 ° C at a pressure ranging from 1 to 5 bar. When using pressurized steam, the anchoring point and the reinforcing anchor are simultaneously heated, incoherent parts and dust are removed, while at the same time creating favorable conditions for foam expansion, such as PUR foam.

It is also possible to implant the expansion mass at low outside temperatures, at temperatures below 15 ° C to the freezing point. The expansion mass can be implanted at normal ambient temperatures of about 20 ° C and above, but also due to heating this can also be done at low temperatures above freezing, which has not been possible so far.

Through at least one aperture at different angles to the horizontal plane, through the building insulation of the thermal insulation system, comprising e.g. 25 insulating panels, one end is located on the outer surface of the insulated structure and the other end results in an air gap and / or closed air cavities and / or connected air cavities formed between the insulation and the building structure. A measuring probe is inserted into the aperture for measurement and inspection, or optionally for expansion and / or treatment, an expansion mass, e.g. adhesive adhesive targets on both sides and / or an expansion anchor is implanted to create adhesive anchoring points in the air gaps and / or air cavities between the building insulation and the building structure.

The construction system according to this technical solution as a construction product arises only after installation on the insulated wall. Implanted adhesive targets and / or anchors in the air gaps and / or 35 air cavities prevent sagging of the insulation boards and thus replace the original adhesive fences of the ETICS contact systems.

Examples of technical solution

Specific exemplary embodiments are illustrated in Figures 1 to 8. Contact and non-contact thermal insulation systems in the building industry representing a construction product mounted on a building structure. Building structures comprising masonry 1, building insulations such as insulating boards 3, among which are air gaps 2 and / or air cavities 6, with an adhesive layer comprising, for example, adhesive fences 4 and / or adhesive targets 8. Through the shell of the building structure, through building insulation of the insulation system, at least one opening 7 is formed at different angles with respect to the horizontal plane. Its one end is located on the outer surface of the insulated structure and the other end results in an air gap 2 and / or a closed air cavity 6 and / or connected air cavities 6 formed between the insulation and the building structure. A metering probe 11 is inserted into the aperture 2 for measurement and inspection, optionally subsequently for the purpose of remediation and / or modification, an expansion mass, e.g. adhesive adhesive targets 8 on both sides and / or an expansion anchoring element 9 is implanted which creates adhesive anchoring points in the air gaps 2 and / or air cavities 6 between the building insulation and the building structure.

In this case, air gaps 2 and / or air cavities 6 situated between the building structure and building insulation of the thermal insulation systems in the building are preferably used to inspect and / or remediate and / or modify these insulation systems.

Example 1 (Fig. 1, 2)

Figures 1 and 2 show a contact system that is certified in such a way that on an adhesive rail 4 and adhesive targets 8 where closed air cavities 2 are formed between the wall 1 and the insulator 3, inserting the steam probe 10 into the measuring hole 7 and pressurizing it is determined whether the air cavities 6 are actually enclosed within one insulating plate 3. If so, the pressure steam returns back through the measuring orifice 7. The measurement in the cavity 6 measures the parameters in the cavity 6 so that for example temperature corresponds to ° C, humidity 80% and 5 air movement 0 m / sec.

Example 2 (Fig. 3,4)

Figures 3 and 4 show an ETICS contact system with adhesive targets 8 and an intermittent adhesive fence 4 which interconnects the air cavities 6 under the individual insulation boards

3. This results in unspecified air gaps 2, which allow air movement 5, while the adhesive fence 4 and the adhesive target 8 do not reach, for example, 40% of the area of the insulation board 3, according to the ETICS certificate. This condition is detected by the measuring probe 11 through the measuring orifice 7, where the air movement shows, for example, 0.2 m / sec, a temperature of 15 ° C and an air humidity of 80%. The vapor pressure, eg 4 bar, is dispersed in the air gap 2. Implantation of the expansion anchor 9 with an unspecified mesh spacer and PUR foam creates new anchoring points to replace the detected insufficiency of the adhesive surfaces formed by incomplete adhesive fence 4 and adhesive targets 8. Input steam through the steam nozzle 10, through the metering orifice 7, moistens and heats the air gap 2 up to 30 ° C. Detected condition does not correspond to ETICS. Due to the interconnection of the cavities 6 there is an air flow and insufficient ad

-5GB 21427 U1 hezi. It is created either by a cushion effect by marking the contour of the expansion layers or by directly loosening the adhesive layer with the dilapidated plaster.

Further, it is described how to restore the adhesion of the released ETICS contact thermal insulation stack. The convex position is returned to the original plane by means of a suitable pressing device. A hole 7 is drilled across the stack of insulation boards 3 up to the substrate. The expansion anchor 9 with a diameter of 14 mm is inserted. A steam nozzle 10 is introduced into the armature 9 and heated at a temperature of up to 140 ° C for about 5 seconds. After the nozzle 10 has been withdrawn, the anchor 9 is switched on with winter PUR foam. During installation, the outdoor temperature is 0 ° C. The steam enters the air cavity 2 below the insulator and heats the conductive materials and the air near the spacer to more than 20 to 30 ° C. ίο This allows the foam to accelerate from 20 to 10 min. At the same time, moisture is supplied by condensation of the steam, which is necessary for expansion. The expansion of the PUR foam slows down the cooling of the layers under the insulating plate 3. After the foam has matured, the insulating layer is locked in position in the required position by a high adhesive and anchoring effect of at least 450 N per piece of expansion anchor 9.

Example 3 (Fig. 5, 6)

Figures 5 and 6 illustrate a contact system where the ETICS certification is not adhered to by bonding only to the adhesive targets 8. This creates not closed air cavities 6 but an open air gap 2 that fully allows air 5 to move in gap 2. Pressure vapor in gap 2 disperses 20 and does not return back through the inlet. Together with the measuring probe 11, it shows that the insulation board 3 is not cohesive with the wall 1. This condition indicates the need for anchoring by expansion anchor 9.

Example 4 (Figs. 7, 8)

Figures 7 and 8 show an embodiment of a certified contactless system where the insulating plates 3 are attached to the wall 1 by means of adhesive targets 8 which lock the insulating plate 3 until anchored by the expansion anchor 9. Thereafter, the adhesive targets 8 lose their importance. The load is transferred to the wall 1 by the resulting expansion anchors 9. Due to the low outside temperatures, eg around 0 ° C, the air gap 2 is heated by the steam nozzle 30 10 through the opening 7 and the components below the insulating plate 3 by steam from the steam nozzle 10 through an opening 7 to a temperature of 20 ° C. This accelerates the expansion of the PUR foam of expansion anchor 9 by 50%, relative to the expansion of the PUR foam under normal climatic conditions.

More specifically on the use of the new solution according to this technical solution:

First of all, it is necessary to determine in case of thermal insulation constructions whether contact insulation is carried out according to ETICS certification, ie whether it is really a contact insulation system.

In the event of defects in the anchor and adhesive layer, a new anchor 9 with expanding filler can be implanted, thereby completing the missing original adhesive layer, which should have consisted of an adhesive fence 4 and adhesive targets 8 on an area of 40% of the insulator. Addition of this adhesive layer is accomplished by heating and wetting the anchoring point to accelerate expansion even at low outdoor temperatures. 40 This improves the cohesion of the insulator at the anchorage point. At the same time, local steam contamination by fungal and racial spores is reduced by steam exposure when heating anchoring points. Also, the crystalline salt formed in the air gap 2 and air cavity 6 in the surface of the building structure is destroyed or substantially reduced.

If it is found that the insulation is carried out by contactless technology, it is only necessary to check the condition and function of the air gap 2, or to remove incoherent parts of eg debris arising from dilapidated building surfaces under the insulation.

-6GB 21427 U1

As a precaution, it is advisable to carry out random and periodic inspections of the adhesive layer under the insulator in case of left-hand thermal insulation in order to determine the remediation measures in a timely manner if the condition of the insulation layer requires it.

The necessary remediation is carried out in the most hazardous layer, which is the adhesive layer in the air gap 2 behind the insulator. The air gap 2 is the space between the insulator and the building structure and has an important function in terms of optimizing the diffusion resistance of the insulated building structure.

For the initial basic inspection, it is sufficient to drill across the insulation stack, eg consisting of a facade layer, insulation board 3, air gap 2, adhesive layer ie adhesive rail 4 or adhesive targets 8, inspection hole 7, and then make measurements to determine diagnostics of the state of the insulating stratum and its adhesion to the substrate, eg wall 1. For example, a hole 7, about 12 to 14 mm, can be drilled for a measuring probe 11 or a steam nozzle 10 to determine the necessary parameters under the insulating plates. the parameters are understood to be the temperature, humidity and velocity of the air flow and movement 5 in the air gap 2 or in the air cavity 6, and the adhesion of the adhesive layer. The air temperature depends on the construction of the building, the type of insulation layer chosen, the climatic conditions at the building site or interior.

E.g. the following values were measured for a family house with non-contact thermal insulation: outdoor air temperature of 21 ° C, the temperature in the air gap 2 between the masonry 1 and the insulation board 3 was in the opening 2 located 0.5 m above the foundation 23 ° C 1.5 m above the foundation 22 ° C, and at a height of 3 m above the foundation 22.5 ° C.

Air humidity in the air gap 7 above the foundation of 0.5 m was measured 29%, at a height of 1.5 m above the foundation 28% moisture, and at a height of 3 m above the foundation of the building about 26% humidity. The humidity depends on how much moisture has been enclosed during installation. Further increase or decrease of humidity is influenced by the condition of the building structure and by the type of insulation system used and its quality. Humidity can increase up to 90%. These findings demonstrate the correct and irreplaceable function of the air gap 2 in terms of diffusion and moisture transmission of the building structure for healthy living.

The airflow in the air gap 2 affects the humidity and evaporation of moisture from the outer layers of the air gap 2. In well-functioning thermal insulation systems, the air flow rate in the air gap 2 is regulated according to the required parameters of optimal physical properties of the building. In some cases, the air flow may not be intense unless required by the physical properties of the buildings, diffusion, moisture, thermal gradient, thermal insulation and waterproofing properties of the building.

By sucking the air out of the opening 7, any contamination, i.e. the concentration of harmful gases or mechanical particles, is detected, or undesirable fungal and algae deposits can be detected. However, the values are assessed by hygiene experts.

The remediation opening 7 is formed at the locations of the detected defects for implantation of the anchoring system and / or adhesive targets 8. The remedial opening 7 should not pass through the original adhesive layer. If the opening 7 passed through the adhesive layer, it would not allow a fully functional expansion anchor 9 to be formed.

If the opening 7 is treated with steam from the steam nozzle 10, which has been de-condensate-free, the anchoring point is ready for foaming.

A steam surge at a pressure of at least 3 to 4 bar, at a temperature of 105 to 140 ° C, fills the air cavity 6 of the contact systems below the insulator and returns around the steam nozzle 10. This proves that the air cavity 6 is actually closed behind the insulator. as specified in the ETICS contact systems certification. Perimeter gluing according to certification will not let steam under surrounding insulators. If gap 2 behind the insulator is not pressurized and the vapor does not return, the vapor pressure is increased to 4 bar. If the steam does not return even at this pressure, it is obvious that the certified procedures have not been followed and an unspecified air gap 2 has formed under the insulator. This means that there is the possibility of an unforeseen reduction in the insulation function and the risk of system destruction.

-7GB 21427 U1

If steam under the insulator escapes into adjacent gaps and voids, it is necessary to take measures to detect the placement of the insulated joints under the plaster and create lateral shadowing at the horizontal and vertical joints or by applying a straight slat; where there are joints, gaps between the lath and the plaster are created. By measuring the width of the insulation boards used from the skirting board, the joint can be determined. Incoherent spots are detected by tapping the hollow sound. In the ETICS contact thermal insulation system, when using a polystyrene foam insulator, the normative of tensile strength, perpendicular to the insulator plane, is set to 100 kPa, which is practically unattainable. The steam test is carried out for about 5 to 10 sec.

For both contact and non-contact thermal insulation systems, either anchoring systems and / or adhesive targets 8 are implanted as required. The anchoring systems may be, for example, a net spacer, a metal screw, and the like. Adhesive targets 8 of PUR foam can be implanted with or without anchoring elements. The uneven insulating face surface of the insulator can be adjusted to its original position by means of a pressing device (not shown). Implanted expansion anchors 8, foamed with expandable plastic, do not form undesirable thermal bridges, and the adhesive targets 8 formed in the air gap 2 simultaneously support the edges of all adjacent insulating plates 3 thereby preventing them from sagging.

This will fix the entire insulating stratum and remediate the substrate by restoring adhesion at the anchoring points. In the case of minor defects, only adhesive adhesive targets 8 without spacers or expansion anchors 9 can be implanted.

The anchoring systems are installed through the repair holes 7 through the insulator, or they can pass through the adhesive layer and / or through the air gap 2 and extend into the building structure.

It is desirable that all sanitation holes 7 be steam-treated, cleaned from loose parts, moistened and heated.

The inspection and remediation is completed by filling the opening 7 and color matching the facade. If the façade has already been devalued before the renovation, the color scheme of the whole surface is suitable.

If a leak in the air cavity 6 is detected, the substrate under the insulator can be prevented locally by increasing the pressure for a short time up to 4 bar. The cohesive parts, salt crusts and the like are removed. The plurality of inspection openings 7 are selected according to the condition and adhesion of the insulation stack. Incoherent parts, if they do not fall between the adhesive targets 8 and the playpen 4, remain behind the insulator permanently, do not have a major effect on the function.

The anchoring point is heated locally so that the temperature corresponds to the requirements of a good connection. In case of anchoring of the thermal insulation layer, the temperature at the anchoring point is maintained for several minutes, which is sufficient for the actual mechanical or chemical anchoring process. The heating method may vary depending on the anchoring method and the type of anchoring components. For heating it is possible to use foreign heat source, contact or contactless, wet and dry. In case of sufficient thermal conductivity of the components of the thermal insulation system and their accumulation, it is also suggested to preheat them before inserting them into the anchoring point. Where anchoring involves chemical processes requiring moisture, steam or hot water is preferably used. Contactless heating with hot air or steam also heats the surroundings of the anchorage point under the insulator. The insulation layer prevents rapid cooling and keeps the temperature above the outside temperature.

The net spacers, in the case of using steam as a heat source, heat not only the anchoring place, but also the wider surroundings including air gap 2. The steam is able to disinfect the space behind the insulator and moisten the anchoring space. This creates suitable conditions for expansion and tack of the PUR foam. At the time of expansion by closing the anchorage point, the elevated temperature remains below the insulating layer for much longer than with a conventional anchoring method. Such a method allows the anchoring operation to be accelerated by up to 50% and the PUR foam consumption reduced by up to 30%.
