New Sarnafil Self Adhered membrane cuts installation time

Sarnafil G410 FSA self adhered hot air weldable roof membrane

• combines all the traditional and proven advantages of a Sarnafil membrane with fast and easy installation thanks to a strong self adhered attachment method
• instant adhesion means time and money can be saved by all parties – installers, specifiers and building owners
• quick turnaround and shorter times on site
• peel and stick application method of Sarnafil Self Adhered provides instant wind uplift resistance through the self adhesive backing

This multi layer synthetic roofing membrane is a premium quality polyvinyl chloride (PVC) material with an inlay of glass non-woven for dimensional stability and self adhesive polyester fleece backing. The membrane contains ultraviolet light stabilisers which assist weathering in direct exposure and is flame retardant.

Suitable for new construction and refurbishment projects on smooth substrates, Sarnafil Self Adhered is prepared with an uncoated welding edge to ensure that a strong welding seam is achieved in the overlap.

With no built in stress at the time of production the membrane is a dimensionally stable product.

Installation could not be simpler

Just a case of align, peel, stick and seal. The membrane is rolled out and aligned then the release liner peeled off and using a brush or squeegee, to prevent blisters, the membrane is adhered to the substrate. To fully press down the membrane it is recommended that a water-filled or steel roller be used. An appropriate primer must be used together with the recommended substrate material.

With its lacquer coated surface Sarnafil Self Adhered maintains its top quality aesthetic appearance for a long time and like all Sarnafil membranes comes with the company’s industry leading guarantees. In addition the new membrane is BBA certified in excess of 40 years.

Prior to its launch the new self adhered roofing membrane was trialled with a number of contractors and found an enthusiastic response. The speed of installation and reduction of time on site to complete the project was noted by many during the field trials, as was the adhesion strength.

• Stuart Harding, contracts manager at RLW Roofing Ltd: “The launch provided ourselves and other registered contractors with an introduction to innovative new products and construction practices designed to ensure that we can continue to be at the forefront of developments within our industry. It means we can offer our clients the complete flat roofing solutions they require. From the launch day demonstration and our involvement with the field trials, we have been extremely impressed with the quality, the ease of installation and the end finish of the Sarnafil Self Adhered membrane. We can see this membrane offering unique opportunities on projects requiring a fully adhered roofing system where the ease of installation and reduction of COSHH hazards will be of great benefit.”
• Grey & Jarrett: “During the pre-launch trials other registered contractors noted the easier application and advantage of not having to open, stir and apply adhesives on site. “It’s very fast to install, very good to weld – all in all a very good membrane and we will be using it more.”
• Barclay Roofing: ”Fantastic, so quick and easy to lay and no waiting for adhesive to go off.”
