Application

Torch-on roofing membranes should be installed in accordance with BS 8217: 2005,
Code of Practice for Reinforced bitumen membranes for roofing, and to IKO recommendations.
The application should follow the recommended good practices for torch-applied membranes.
Care must be taken when applying torch-on in close proximity to combustible materials, decorative
coatings and heat sensitive materials.

Apply torch-on roofing by melting the heat dispersible backing and coating to create a molten flow in
front of the roll. The flame of the torch should be applied at the low point where the roll meets the underlay.
As the film and bitumen melts, roll the roofing forward. NB. A bead of bitumen must exude from all lap joints to ensure a seal.
