Product Overview

Sarnafil® G 410-15 L is a multi-layer synthetic roof waterproofing membrane based on polyvinyl chloride (PVC) with a glass non-woven inlay for dimensional stability. At 1.5 mm thick, with a white reflective top surface and dark-grey underside, it is designed for exposed flat roofs and for ballasted systems such as green roofs, utility roofs, inverted roofs and gravel roofs. Seams are joined by hot-air welding to form a continuous, fully watertight skin, while a solar reflectance of 0.80 helps reduce roof surface temperatures and cooling loads. It suits architects, roofing contractors and developers seeking a durable, energy-conscious single-ply solution. Space Arc Engineering, an authorized Sika distributor in India, supplies Sarnafil® G 410-15 L for commercial and infrastructure roofing projects.
