Sarnafil® G 410-15 L Felt
Felt-backed glass-reinforced PVC single-ply membrane for fully bonded adhered roofs
Product Overview
Sarnafil® G 410-15 L Felt is a multi-layer PVC roof waterproofing membrane that pairs a glass non-woven inlay with a polyester fleece backing, giving 1.5 mm of robust, dimensionally stable waterproofing. The fleece underside is purpose-made for full adhesion, so the membrane is bonded down with Sarnacol® adhesives and the laps hot-air welded into a seamless skin. With a white, UV-stabilised, lacquer-coated top surface delivering a solar reflectance of 0.80, it suits fully bonded, exposed roofs in demanding climates. Roofing contractors and specifiers choose it where wind uplift, smooth substrates or adhered build-ups call for a fleece-backed sheet. Space Arc Engineering, an authorized Sika distributor in India, supplies Sarnafil® G 410-15 L Felt for adhered roofing projects across the country.

Frequently Asked Questions
What is the difference between Sarnafil® G 410-15 L and the Felt version?
The Felt version adds a polyester fleece backing to the PVC membrane, making it ideal for fully bonded adhered roofs, whereas the standard G 410-15 L is used in exposed and ballasted systems.
How is Sarnafil® G 410-15 L Felt installed?
It is fully bonded to the substrate using Sarnacol® adhesives, and the overlapping seams are joined by hot-air welding with equipment capable of at least +600 °C.
What thickness is Sarnafil® G 410-15 L Felt?
The membrane is 1.5 mm thick with a mass per unit area of approximately 2.15 kg/m², supplied in 20.00 m x 2.00 m rolls. Refer to the TDS for tolerances.
Is Sarnafil® G 410-15 L Felt UV resistant?
Yes. It is formulated with UV light stabilisers for exposed service and carries a white reflective surface with a solar reflectance of 0.80.
