Technical Specifications

Positioning of the edge stop beam
Spread a breathable membrane mantle of non-woven fabric
Lay down STIFERITE’s Class S panels
(alternative: STIFERITE’s GT)
Spread a waterproofing and breathable membrane of non-woven fabric
Lay down and install laths in the panels and the structure underneath
Lay down and install metal profiles to support the tiles
Lay down and install regular or clay tiles and ventilation elements (bird protector grill, ventilated ridge)

Instructions and Guidelines
Polyurethane foams are able to withstand high temperatures (+90/100°C) that accumulate on the protective element subjected to the sunlight

The use of metal profiles to install the tiles available as an accessory of the Isoventilato system, is a valid alternative to the traditional double wood laths method

Also see: the installation procedure

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:
