The TecnaFlex Torch-On Charcoal Mineral Cap Sheet (1m x 8m x 4mm) is a premium-quality SBS modified bitumen roofing membrane, designed to provide long-lasting waterproof protection for flat roofs. Manufactured with a durable polyester reinforcement and finished with an attractive charcoal mineral surface, this high-performance cap sheet delivers exceptional flexibility, weather resistance, and durability for both domestic and commercial roofing applications.
With its 4mm thickness and 44kg roll weight, TecnaFlex offers a reliable roofing solution that performs in demanding weather conditions, remaining flexible in temperatures as low as -20°C.
TecnaFlex membranes are manufactured using SBS (Styrene-Butadiene-Styrene) modified bitumen, providing superior elasticity and resistance to cracking compared to traditional roofing felt. The reinforced polyester core enhances tensile strength and dimensional stability, making it suitable for roofs exposed to changing weather conditions.
For maximum performance and longevity, this cap sheet should be installed as part of a two-layer torch-on roofing system over a compatible SBS underlay.
Please note: The membrane should be fully rolled out prior to installation to allow it to relax before application.
This membrane is designed for professional torch-on application only and should be installed using appropriate roofing equipment and safety procedures. The plastic film on the underside remains in place until installation and is melted during the torching process to create a secure waterproof bond.
When installed as part of a two-layer SBS roofing system, the TecnaFlex Torch-On Cap Sheet offers a 20-year guarantee, delivering dependable protection against rain, UV exposure, frost, and temperature fluctuations.
