Technical Bulletin: Picture Frame Method
For Safer Use of the Flame!


Heat-welded membranes remain one of the most established technologies on the market when it comes to roof waterproofing thanks to their ease of installation in various conditions and types of worksites. However, using a propane torch is not without danger and requires particular care since it involves significant risks to the safety of occupants of the building and installers.
By demarcating areas most susceptible to fire risk, such as membrane perimeters and flashings, with flameless solutions, it is possible to create an area within these limits where the risk of fire related to the use of the torch is greatly reduced.
When it comes to installing heat-welded solutions, don't play with fire—opt for a safer installation method like the picture frame technique!
