BBA Agrément Certificate
Certificate type
Year adhered roof covering system.
PVC-P single-ply membrane for adhered and ballasted warm roofs.
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.
Performance:
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 localized replacement and repair.
Should the maintenance cycle not be followed, Sarnafil G/S membranes have been given, in the opinion of the BBA, a life expectancy of 'in excess of 35 years'.
Installation:
In adhered applications, Sarnafil G410-EL is adhered directly to the substrate or a suitable thermal insulation board with Sarnacol 2170. Laps are then hot air-welded to form seams which are stronger than the membrane itself.
In warm-ballasted applications, the G410-EL membrane is loose laid, with all overlapping joints hot air welded prior to the application of a protection/ filter fleece and the chosen ballast system.
Installation is carried out by Sarnafil trained contractors.
