Torch-On Roofing Felt - Underlay 16mtr x 1mtr 270233


Debotec Deflector Torchon Underlay (16m x 1m) is a high-performance bituminous membrane designed for use as a reliable, durable base layer in built-up roofing systems. Manufactured from robust, reinforced materials, this underlay provides exceptional waterproofing and structural stability, making it ideal for professional roofing applications across both residential and commercial projects.

Product Features/Specifications:

This torch-on underlay features a high-quality bitumen coating reinforced with polyester or glass fibre for superior tensile strength and flexibility. Its smooth, consistent finish allows for easy application and ensures strong adhesion to primed surfaces, providing a secure foundation for subsequent layers of waterproofing membranes.

Detailed Product Benefits:

The Debotec Deflector 270233 is engineered to deliver long-term performance in demanding environments. Its advanced formulation resists temperature fluctuations, UV degradation, and mechanical stress, ensuring a watertight seal even under extreme conditions. The underlay’s torch-on application method guarantees uniform coverage and bonding, minimising the risk of water ingress. With enhanced dimensional stability and resistance to blistering, this product supports the structural integrity of the entire roofing system, extending service life and reducing maintenance costs.

Applications and Versatility:

Perfect for use as an underlay in multi-layer torch-on roofing systems, the Debotec Deflector is suitable for flat, pitched, and curved roof structures. It can be applied to various substrates, including concrete, timber, and metal decks, making it a versatile solution for new builds, refurbishments, and repair projects. Its durable waterproofing properties also make it suitable for use in cold roofs, warm roofs, and inverted roof assemblies.

  • High-strength polyester or glass fibre reinforcement for maximum durability
  • Excellent waterproofing performance for long-term protection
  • Heat-activated bitumen coating for secure, torch-applied installation
  • Superior flexibility and dimensional stability under varying temperatures
  • Compatible with a range of roof build-ups and top-layer membranes
  • Resistant to UV exposure, blistering, and mechanical wear
  • Designed for professional application on new or refurbished roofing systems

Technical Specifications:

  • Roll Size: 16m x 1m
  • Type: Torch-on bituminous underlay
  • Reinforcement: Polyester or glass fibre (varies by product batch)
