The GammaStone AIR panel lends can be used perfectly as the infilling element of in curtain walls, both with mechanical retention both with structural one.
Regardless of the technology used for the structure of the curtain wall (mullion or transom, independent cells, or more traditional windows), the GammaStone AIR panels can be used as infill ensuring the highest value external finish. It also provide the best protection from flames coming from the inside of the building thanks to the steel sheet on the back of the panel itself. In this way, the fulfilling is completely incombustible from flame coming from the inside or the outside the building. The rear stainless steel sheet is also perfectly compatible with the normal structural silicone (mono and bi-component) used in window frames for structural bonding of the glass and sheet metal panels. Therefore the panel GammaStone AIR can be pasted structurally on the façade grid, after the ordinary checks required by current regulations and from international technical guidelines (For. Ex. ETAG002 - GUIDELINE FOR EUROPEAN TECHNICAL APPROVAL FOR STRUCTURAL SEALANT GLAZING SYSTEMS (SSGS).
According to the UNI EN 12664, the panel GammaStone AIR guarantees a thermal transmittance of 4.22 W / m2 ° K, contributing to the thermal insulation of the building despite the minimal thickness and the high aesthetic value.
