Innovative sandwich panel Alubel 28
Tek 28 Piano is simply the natural evolution of 28 family. It was born combining our long experience in sandwich panels with that in corrugated sheets, trying to create a new type of double skin sandwich panels not yet present on the market.
Functional features
-
Special lateral overlapping
The overlapping of a corrugation and a half is probably the most important characteristic, giving a better guarantee for watertightness even with low slopes.
-
Drainage channel
Special drainage channel on the lower profile to reduce condensation risk.
-
Lateral seal
An essential element to obtain high performances out of a sandwich panel, enhancing the lateral coupling.
-
High walkability
The specific shape has been given to optimize walkability.
-
Higher permitted load
Thanks to its geometry, Tek28 Piano has higher load bearing capacity compared to a standard sandwich panel.
-
Higher polyurethane core
Thanks to close corrugations, surface of the polyurethane core of the panel is higher than that of a normal sandwich panel.
