Benefits

• Durable performance
• Strong
• Flexible
• Torch application
• Easily detailed

Application

• Designed for use with torch-applied roofing membranes
• When used as the first layer of a torch-applied, built-up felt roofing system, this will provide a positive partial bond to prepared non-combustible substrates
• 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
• A bead of bitumen must exude from all lap joints to ensure a seal

Recommended system:

• Venting layer
• 2mm underlay
• 4mm mineral cap sheet
• Replace mineral cap sheet with 4mm sanded if laying promenade tiles
