1. SUBSTRATE

Typical: steel deck

• The substrate will provide for the required insulation fasteners' minimum pull-out resistance^:
  steeldeck: 1.700 N
  plywood: 2.000 N
  concrete: 2.500 N
• Although dead level is acceptable, a slope is recommended for roof drainage.
• All vertical surfaces will be compatible with the Flashing/Substrate Adhesive.*

* Refer to technical data sheet
^ When insulation is mechanically secured.The other option is to use Insulation Adhesive

2.VAPOUR CONTROL LAYER

Typical: 200µ polyethylene film

• The material type will be specified if/as required by the dew point calculation.
• Install PE loose-laid with 100mm overlap and taped seam, other types as specified by manufacturer.

3. INSULATION

Typical: 30kg/m³ bitumen faced polyurethane

• Class B, Class C or Class D UEAtc approved roofing boards with the required thickness and compatible with FB-SF Adhesive are also acceptable.
• The boards will be mechanically secured as per the insulation manufacturer's recommendations.
• The boards can also be adhered (on a compatible substrate) using Insulation Adhesive.*
• Taper the joints at roofdrains.

* Refer to technical data sheet

4.SINTOFOIL MEMBRANE

Typical: FB/Grey/1.2 mm

• Install with overlap and welded seam as per specifications.^
• Adhere to the insulation using FB-SF Adhesive* with the coverage rate as per the wind uplift pattern.
• The membrane will be mechanically secured at roof perimeter and around protrusions.

* Refer to "welded seam technology" section

5.TRAFFIC

Typical: smooth round river washed gravel, ø 12-35 mm, 60kg/m² min.

• The installed membrane will be protected from following other trades' work.
• Walkways (if required): SLM walkways or a 1.5 mm Sintofoil roll 1.05 m wide, welded to the membrane.

Notes:
The architect is responsible for the wind study and the resulting fastening pattern.
Refer to the local code requirements when applicable. Reroofing projects will be subject to a specific study, including preliminary inspection and pull-out testings.
