Bituminous System - BauderTHERM 'Stripes' System

When to specify...

When a roof covering is reaching the end of its serviceable life, but is essentially still waterproof, the BauderTHERM 'Stripes' system can overlay the existing system to extend the life expectancy of the roof by at least 15 years, providing that the thermal properties of the roof are satisfactory and features torch-free and safe to torch installation on combustible details. This system is only suitable for refurbishment projects.

Safe2Torch industry initiativeBauder Torch-Free Detailing Methods 

Our torch-free detail design specifically delivers secure safe application techniques in the vicinity of combustible construction materials located on, or connected to, the roof such as timber substrates or upstands; abutments to cladding, roof tiles, slates or thatch; or even debris such as dry leaf material that is at risk from ignition.  The application methods meet NFRC Guidance Document 'Safe2Torch'
