Technical Specifications

Spread a breathable membrane mantle of non-woven fabric
Positioning of the edge stop beam
Lay down STIFERITE’s GT Wind system oriented with the ventilation laths perpendicular to the gutter
Install the panels using self-threading screws
Lay down security waterproofing membrane (self-adhesive or thermo-adhesive without the use of a flame system) with slate chips’ finish.
Lay down and install regular or clay tiles and ventilation elements (bird protector grill, ventilated ridge)

Instructions and Guidelines
The pre-assembled GT Wind system is installation as a single element that includes: the insulation layer, air ventilation chamber and the surface layer made of OSB3 board.

The air ventilation chamber made of polyurethane foam laths is 40mm in height.

The surface layer in the STIFERITE’S GT Wind system is made of multi-layer phenolic plates of dry flakes, oriented and pressed at high pressure (OSB3) in thickness of 12 mm

The tables indicate the suggested thickness of Stiferite’s panels based on

Climate Zones
Current legislative set limits of thermal transmittance
And the following composition of the structure:
