Technical Specifications

• Prepare installation procedure
• Screen or vapour barrier
• Lay down STIFERITE’S Class B panel
  (alternative: STIFERITE’S Class S)
• Lay down two layers of mantle s, the first  made-up of a bituminous plastomeric polymer 4mm thick, reinforced in TNT with stabilized continuous string polyester. The second layer of bituminous waterproofing with Slate Chips and polyester fibre reinforcement, maximum weight ≥ 4 kg/m². 

Instructions and Guidelines
The Slate Chips’ layer protects the waterproofing mantle from weather conditions and reduces the maintenance schedule to a minimum.
Always use high quality products and aim for a perfect installation of the entire “package”.
The complementary products are indicated only as a good level of quality standard.

The installation can be made in several methods: Using adhesives or single-component polyurethane foam in a can, panels laid over a continuous and uniform coating of hot bitumen,  laid on to a torched liquefied bitumen vapour barrier, or mechanically fixed with anchors.

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 or Class S
Climate Zone	DLgs 311/06	TAX deduction MD 65% DM 26/10/2010
A	60 mm	70 mm
B	60 mm	70 mm
C	60 mm	70 mm
D	70 mm	90 mm
E	80 mm	90 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)
