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'
