Adhered PVC-P single ply roofing membrane for use on cold roof applications.
PVC-P single-ply roofing system for use on cold roof applications.
- Waterproof membrane:
Sarnafil G membranes are manufactured using a state of the art extrusion coating process that eliminates shrinkage and plastic memory and produces a dynamically stable membrane. In the coating process, a glass fibre carrier is coated on both sides with liquid Plastisol, prior to the application of a lacquer coating on the upper surface and laser marking of the membrane surface for identification. The unique lacquer coating eliminates the need for biocides, provides the membrane with an easy to clean surface and prolongs the life of the membrane by reducing plasticiser loss.
The process enables between 2% and 5% of recycled material to be used in the production of new membranes.
Roller applied solvent-based contact adhesive (red-coloured), designed to adhere Sarnafil G410-EL or G410-ELF waterproof membranes to substrates of steel, timber, concrete or approved thermal insulation boards. Substrates should be solvent-resistant, dry and free of oil and grease.
Spray applied PU-based contact adhesive (red-coloured), designed to adhere Sarnafil G410-EL or G410-ELF waterproof membranes to substrates of steel, timber, concrete, or approved thermal insulation boards. Substrates should be solvent-resistant, dry and free of oil and grease.
Certified by BBA, in their opinion, to have a "life expectancy in excess of 40 years" for exposed applications, with periodic maintenance as stated below.
A planned maintenance cycle, including inspections by the Certificate holder at minimum intervals of five years, should be introduced if an extended service life is required. The Certificate holder can advise on methods of extending the service life. This could include the use of thicker membranes, specific maintenance requirements or localised replacement and repair.
Should the maintenance cycle not be followed Sarnafil G/S membranes have been given, by the BBA in their opinion, a life expectancy of "in excess of 35 years".
Sarnafil G410-EL is adhered directly to the substrate or a suitable thermal insulation board with Sarnacol 2170 or 2172 spray adhesive. Laps are then hot air welded to form seams which are stronger than the membrane itself.
