Sarnafil® S 327-15 L
Polyester-reinforced PVC single-ply membrane for mechanically fastened exposed roofs
Product Overview
Sarnafil® S 327-15 L is a polyester-reinforced, multi-layer PVC roof waterproofing membrane engineered for mechanically fastened roofing systems. At 1.5 mm thick with a white matt top surface and dark-grey underside, it is suited to directly exposed roofs across all climatic zones. The internal polyester scrim delivers high tensile strength to resist wind uplift, while hot-air welded laps create a continuous, fully watertight skin. A white surface gives 0.80 solar reflectance to help keep roofs cooler, and the membrane is fixed using Sarnabar®, Sarnafast® or field fastening systems. It serves contractors and specifiers roofing large-span steel-deck buildings. Space Arc Engineering, an authorized Sika distributor in India, supplies Sarnafil® S 327-15 L for mechanically fastened roof projects nationwide.

Frequently Asked Questions
What is Sarnafil® S 327-15 L?
It is a 1.5 mm polyester-reinforced PVC single-ply roof waterproofing membrane designed for mechanically fastened, directly exposed roofing systems in all climates.
How is Sarnafil® S 327-15 L fixed to the roof?
It is mechanically fastened using Sarnabar®, Sarnafast® or field fastening systems, and the overlapping seams are hot-air welded at a minimum of +600 °C to form a watertight membrane.
What is the tensile strength of Sarnafil® S 327-15 L?
The membrane offers a tensile strength of at least 1000 N/50 mm in both directions, with tear strength of at least 200 N, giving strong resistance to wind-uplift forces.
Is Sarnafil® S 327-15 L a reflective membrane?
Yes. Its white surface provides a solar reflectance of 0.80, helping reduce roof surface temperatures and contributing to energy-efficient cool-roof performance.
