Tecnatorch Charcoal SBS Torch-On Mineral Felt

Tecnatorch SBS Torch-On Mineral Felt is a premium, high-performance cap sheet built for roofers who demand quality, durability, and efficiency. With a sleek charcoal mineral finish, this 4.2mm-thick felt is perfect for both new builds and refurbishment projects, offering a long-lasting solution that doesn’t compromise on performance or style. Manufactured by Icopal, a leading name in roofing technology, Tecnatorch is designed for use in a three-layer built-up system. This includes a vented base layer (VBL), followed by a torch-on underlay, and topped with the Tecnatorch cap sheet for full weatherproof protection. Once installed by an Icopal-approved contractor, and following their installation guidelines, this system is covered by a 15-year guarantee—providing peace of mind that your roof is protected for the long haul.

Why Choose Tecnatorch?

This product isn’t just about great looks—though the charcoal finish certainly adds a modern touch. It’s built with SBS-modified bitumen, a blend of bitumen and synthetic rubber (Styrene-Butadiene-Styrene), which gives the felt flexibility, elasticity, and excellent cold resistance. It adapts well to structural movement, remains robust in cold conditions, and forms a highly reliable, watertight seal. Tecnatorch also features cutting-edge mini groove technology, allowing it to be installed up to 30% faster than traditional torch-on felts—while using 25% less gas in the process. It’s safe, efficient, and easier to handle, with a low-flame application method that makes it ideal for contractors prioritising safety and speed on site. Built to Withstand the Elements Tecnatorch is designed with long-term protection in mind. It offers superb resistance against mould, moss, fungi, lichen, bacteria, and freeze-thaw cycles. Its strong lap security defends against wind uplift, while the fully waterproof surface ensures reliable performance during heavy rain or snow. The felt also boasts excellent dimensional stability, allowing it to flex and move with the building—without cracking or failing over time.

FAQs – Tecnatorch SBS Torch-On Felt

Do I need to use the full three-layer system with this felt?

It’s suitable for flat, pitched, and curved roofs and can be applied over surfaces such as plywood, OSB, timber boarding, profiled metal decking, or screeded concrete—making it versatile for many projects.
