3 79-3 EN Structure and functionality of VIP High barrier foil Fleece envelope (Dust protection for the sealed seam) Core of pyrogenic silica with neutral additives Functionality of VIP Heat conductivity of solid state The small spherical shape of the pyrogenic silica reduces the thermal conductivity by contact of solid particles, as between the single particles only punctual transition points occur. IR opacifier Structure of the pyrogenic silica Infrared radiation An IR opacifier reduces as an additive the infrared transmission and minimizes in this way the heat transfer by radiation. Silicon carbide molecules act as miniscule mirrors that reflect the IR radiation. Convection During the evacuation process the number of the air molecules in the VIP element decreases. The remaining air molecules collide less frequently. Each collision transmits kinetic energy and provides in this way the heat transport. Heat is nothing else as the movement of particles.

5 79-5 EN Production of VIP Quality control during the production of VIP Evacuation with internal pressure of 0,3 mbar First measurement of the internal pressure - each component Laser distance measurement Vacuum chamber Measurement principle Second measurement of the internal pressure by laser distance measurement - each component = 2 x 100 % measurement of the internal pressure for an absolute safety!!!

For this reason all VIP panels are coverd with protection covering layers and a safe edge protection in factory. In addition to the prevention of mechanical damages the covering layers undertake the task of the design as well as of the respective required function. According to the construction requirement you can chose between 14 covering layers with technical approval (see page 10). VIP panel + edge and surface protection = QASA component

11 79-11 EN Product data of QASASandwich Sizes: Component: width x height according to the covering layers (see page 10) Thickness: dependent on the thickness of VIP and the chosen material of the covering layer Thicknesses of the VIP core: 10 / 15 / 20 / 25 / 30 / 35 / 40 / 50 mm Tolerances: thickness +1/- 2 mm, measures of length + 2 mm Vacuum insulation panel (VIP): Core material: Pyrogenic silica with bearing fibres and infrared opacifier Density of the core: kg/m³ Thermal conductivity: For the calculated evidence of the thermal resistance the VIP (without protection covering layers) has the rated value of the thermal conductivity of λ = 0,007 W/(mK). This value takes into consideration the aging of the VIP as well as the thermal losses caused by the effect of thermal bridges of the edge area of the VIP panel. Minimum thermal insulation: Components in which VIP panels are used have to fulfill the requirements of the minimum thermal insulation according to DIN , table 3 also in case of a functional failure of the vacuum. The rated value of the thermal conductivity of the damaged VIP is λ = 0,020 W/(mK). Specific thermal capacity: c = ca. 1 kj/(kg K) Fire behaviour: The VIP elements are normally inflammable (building material class DIN B2) Compression strength at a compression of 10 %: σ 10% = 290 kpa By using a more pressure stable core board (apparent density > 220 kg/m³) higher values of the compression strength can be obtained. The value of the thermal conductivity of the VIP panel can thereby marginally rise. Internal pressure: on delivery of the panel < 7 mbar Calculated increase of pressure: ca. 1 mbar / a Temperature resistance: The permanent temperature resistance is defined by the heat sealable coating of the high barrier foil. The constant load of the VIP panels must not exceed a value of 80 C.

14 79-14 EN General manufacturing instructions for QASA/VIP components 1. Transport, storage 1.1 The QASA/VIP panels have to be protected against any mechanical damage during the transport to the place of installation. Do not store vertically on the unprotected panel edge. 1.2 The panels are delivered horizontally on a pallet and have to be transported or temporarily on site in the same way. 1.3 The pallets must not be piled. 1.4 The panels have to be stored protected against humidity and longer solar radiation as well as mechanical damages. 1.5 Max. ambient temperature 80 C. 2. Control of the QASA/VIP components for integrity before mounting 2.1 The delivered QASA/VIP components have to be checked for: 2.2 Visual check for exterior damages (sort out damaged components, if so check for density by ). 2.3 Check for the density of the envelope foil of the QASA components with open edge design (leak can be recognised by envelope foils that lie slackly on the core). 3. Control of the substructure at the place of installation 3.1 The substructure has to be even, smooth and free of sharp elevations or edges. Unevennesses have to be levelled before mounting. 3.2 The substructure has to be clean and dry (please respect the guidelines of the glue suppliers). 3.3 All neighbouring crafts of insulation have also to be checked for a risk potential for the QASA components. 4. Mounting of the VIP elements 4.1 The envelope foils of the QASA/VIP components must not be damaged. Sawing, boring and other mechanical treatment is only possible to a limited extent in the area of the installed EPS/XPS/PUR edge tapes. After an eventual treatment it is necessary to recheck the QASA/VIP components for tightness.

15 79-15 EN General manufacturing instructions for QASA/VIP components 4.2 The gluing of the QASA/VIP components is possible with mineral or polyurethane glue as well as with the standard mounting glue systems. The application rate of the glue has to be in accordance with the used glue (respect the manufacturing instructions of the glue suppliers). 4.3 Mechanical fixation by screwing is only possible for especially therefore designated QASA/VIP components with edge design resp. central bar. Respect absolutely the edge widthes! 4.4 In order to guarantee the tightness at the butt joints to avoid thermal bridges and to compensate dimensional tolerances, the joints have to be filled with conventional insulation materials (e. g. compressed tape, PU construction foam, rope seals). Moisture and humidity have absolutely to be avoided in the area of the butt joints. 4.5 Dimensional tolerances preferably have to be measured not on plane surfaces, but in the external corners. 4.6 The connections to the existing building structure have to be sealed by appropriate sealing or swelling tapes. 4.7 Do not damage vacuum panels by tensile and compression load or by folding. 4.8 Concentrated single loads of the QASA/VIP components have to be avoided. They may be exposed only to a constant, plane load. 5. Assembly personnel, other crafts, users 5.1 The QASA/VIP components may be treated only by instructed and briefed personnel. 5.2 Before mounting it has to be advised on the specific characteristics of the QASA/VIP components and the present General manufacturing instructions have to be respected. 5.3 Craftsmen from the subsequent crafts have also to be advised of the risk of damage of the QASA/ VIP components by mechanical impacts. 5.4 The users have also to be advised of the specific characteristics of the QASA/VIP insulation. 6. Examples for the QASA/VIP application are illustrated in the einfach-sicher-dämmen
