Ensure a strong and reliable roofing system with our premium Torch-On Sanded Capsheet Underlay. Designed for exceptional durability, flexibility, and weather resistance, it’s the ideal foundation for torch-applied built-up roofing systems.

Crafted from 100g glass-based SBS-modified bitumen, this underlay provides superior tensile strength (675 N/50mm longitudinally and 460 N/50mm transversely) and cold bend flexibility down to -5°C. Measuring 26.25 ft (8m) x 3.28 ft (1m) and weighing 63.93 lbs (29 kg), it ensures watertight protection and tear resistance in extreme weather conditions. Suitable as an underlay or intermediate layer, it enhances your roof's lifespan by up to 10 years. Installation is simple—cut to the desired length and adhere with a torch. Pair with our Mineral Capsheet for best results. Store upright on a dry surface above 10°C to maintain optimal performance.
