It is a system that uses dual-layer sheets, the lower layer in trapezoidal sheet, an intermediate layer of thermoacoustic insulating and a top layer in standing seam sheets to ensure complete watertightness.

Through the clips patented E-clip Roofway by Kalzip with galvanized steel core coated with polyamide 6 and reinforcing with glass fibers, reduce significantly the friction coefficient improving the system expansion performance and the thermal transmission coefficient for minimizing heat exchanges between the external and internal environment.

 

Clip polyamide 6 with steel core. Measures 20 to 180mm.

 

 

 

 

For greater efficiency and durability of sandwich systems, should be a study to verify the possibility of condensation. If necessary, it should be adopted vapour barrier.

 

 

 

We have it available in various specifications like polyethylene, asphalt plaid or FR.
