“TLX BATSAFE™ has passed the Snagging Propensity test developed by university academics, Statutory Nature Conservation Organisations and The Bat Conservation Trust”

TLX Insulation Ltd. has been setting standards of excellence in high performance breathable membranes and building insulation for nearly 25 years. We’ve now used our knowledge and expertise to create TLX Batsafe™ – the patented bat friendly breather membrane, approved by Local Authority Building Control (LABC).

Bats are a protected species and play an important role in the ecosystem. Until now when bats are found, only Bitumen 1F felt has been used. This has come at considerable cost to the thermal performance of the roof because 1F felt requires extra rafter space if insulation is used; in old buildings this is often not possible.

Properties with an uninsulated 1F felt roof can release up to 10 tonnes of CO₂ per year. Replacing 1F felt with a breathable membrane and additional insulation between the rafters can improve thermal performance by up to 87% and reduce CO₂ emissions by 57%. These factors have a large impact on global warming and climate change. TLX Batsafe™ is designed with a bat mesh protection system on both sides of the membrane. Unlike 1F felt, TLX Batsafe™ is breathable, lightweight, high strength and easy to handle. Patents granted in 2022.
