Certificate type
Mechanically fastened roof covering system.
Flexible Polyolefine (FPO) single-ply roofing system with non-halogenated fire retardant, designed for mechanical fastening on warm roofs.
System includes:
- Waterproof membrane:
Sarnafil TS77 membranes are manufactured using a specially developed in line extrusion coating process. This coats both sides of a polyester scrim carrier simultaneously with a compounded Flexible Polyethylene and produces a dynamically stable membrane that can accommodate the tensile stresses imposed by mechanically fastened applications.
The process enables between 2% and 5% of recycled material to be used in the production of new membranes.
- Insulation:
Rigid polyisocyanurate foam insulation boards to BS 13166; with foil facing. Available in uniform thickness or tapered.
- Vapour control layer:
A 0.60 mm thick, high-performance, self-adhesive vapour control layer, manufactured from polymer modified bitumen, with glass fibre reinforcement and aluminium foil top layer. Suitable for use in high humidity environments, green roofing systems, loose-laid ballasted warm roof systems and all adhered and mechanically fastened systems. Can be used as a temporary waterproof layer for up to 4 weeks, in strict accordance with the product data sheet.
Performance:
Certified by BBA to have a life expectancy in excess of 25 years.
Installation:
- Waterproof membrane:
Sarnafil TS77 is intended to be mechanically fastened using the Sarnafast or Sarnabar systems. Installation is carried out by Sarnafil contractors, who are specifically trained in the installation requirements of Sarnafil T membranes.
- Insulation:
SarnaTherm S can be attached to the substrate (deck or suitable vapour control layer) by mechanically fastening with SBT tubes and SBIW-70x70 pressure plates.
A vapour control layer will be required when SarnaTherm S is used.
- Vapour control layer:
Loose laid over any smooth surface with all side and end laps overlapped a minimum 80 mm, then sealed with Sarnavap jointing tape. At parapets and upstands, Sarnavap must be carried up to the upper edge of the thermal insulation and sealed to the upstand/ penetration with SarnaVap jointing tape, to form an airtight seal. When installed vertically, Sarnavap must be mechanically fastened along its top edge.
If the surface is rough, a layer of Sarnafil Type T should be used as cushioning layer.
