Prepare installation procedure
Screen or vapour barrier
Lay down STIFERITE’s Class B panel
(alternative: STIFERITE’s Class S)
Installation of waterproofing mantle made of two bituminous membranes with polyester fibre reinforcement, minimum 4mm thick
Positioning of floating squares of washed gravel (40 mm thick), placed over suitable supports only after inter-positioning of membranes as separating layers for protection and levelling

Instructions and Guidelines
Roof top terraces increase the amount of living space, but must ensure comfort and safety of the ambient below it.

In order to guarantee a secure waterproofing seal and eventual maintenance to the finished package, it is of great importance to carefully design and install a perfect package

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's Class B - STIFERITE's Class S
Climate Zone	DLgs 311/06	TAX deduction MD 65% DM 26/10/2010
A	60 mm	80 mm
B	60 mm	80 mm
C	60 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)
