Torch-On SBS Capsheet – Black – Exterior Roofing

Product Overview

This Premium Torch-On SBS Capsheet is supplied in an 8m² roll, offering a durable, weather-resistant finishing layer for flat and low-pitched roofs. It is constructed with a polyester-based reinforcement and modified with SBS (Styrene-Butadiene-Styrene) elastomeric bitumen, providing enhanced flexibility, durability, and crack resistance compared to standard bituminous felts.

The mineral-finished black surface provides a bold, traditional appearance, ideal for urban environments and buildings with slate or dark roof coverings. It also offers effective UV protection, extending the life of the waterproofing system. This capsheet is applied using the torch-on method, fusing the underside bitumen layer to the substrate or underlay to create a secure, watertight seal.
