Technical Specifications

Positioning of the edge stop beam
Fixing of the gutter
Torch down a vapour barrier to the roof top made of bitumen membrane of at least 3 mm thick
Installation of STIFERITE’s Isoventilato panel with laths parallel to the gutter
Seal the joining sections of the panels with waterproofing self-adhesive tape as protection against eventual formation of condensation
Followed by the installation of the sheet metal covering

Instructions and Guidelines
The waterproofing but breathable facer of the ISOVENTILATO panel prevents eventual infiltration even if the roof is damaged.

The laths incorporated into the foam of the panel prevent the formation of thermal bridges and facilitate the mechanical fixing of the sheet metal covering.

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:

Suggested thickness STIFERITE Isoventilato
Climate Zone	DLgs 311/06	TAX deduction MD 65% DM 26/10/2010
A	70 mm	80 mm
B	70 mm	80 mm
C	70 mm	80 mm
D	80 mm	90 mm
E	80 mm	100 mm
F	80 mm	100 mm

Note: For different composition of structures or material, we suggest using the calculation program available online (see: Thermal transmittance and verifications of condensation with Glaser method)
