Polar Weldable Bitumen felt TL2 K-MS 170/4000 – 1 × 10 m

Polar Weldable underlay felt is a high-quality waterproofing layer intended as a base in multi-layer systems for low-slope roofs and other structures where continuous joint tightness is required. The product is delivered in rolls measuring 1 m × 10 m and is fully weldable, meaning the entire surface can be heat-fused with a gas torch for a completely sealed joint.

The material consists of SBS-modified bitumen with a reinforced polyester core (170 g/m²) and has a sanded top surface to facilitate installation. The underside has welding compound under a protective film, making it ready for gas torch installation. 

• Weldable construction ensures maximum sealing and joint security.

• Robust polyester core and bitumen material for long durability even in a Nordic climate.

• Size 1 × 10 m provides good coverage and efficient handling.

• Quick and secure installation with a gas torch.
