What is Bitulen® 180

Bitulen® 180 is a torch-on waterproofing membrane consisting of modified bitumen with plastomeric, atacticpolypropylene (APP) polymers and selected stabilized fillers. The membrane has good resistance to thermal ageing and dimensional heat stability and may be applied in any climate and is particularly suited for temperate and warm climatic area.

Bitulen® 180 is highly resistant to the ageing effects of UV radiation and is not easily damaged from foot traffic during application which is essential for ‘exposed’ roofing where a high quality finish is required.

Bitulen® 180 is reinforced with a rot-proof non-woven polyester stabilized with glass fibres. This ensures excellent dimensional stability and high level performance to the membrane.

Bitulen® 180 is available with a coloured slate chip (mineral) top surface for exposed applications. For concealed or multi-layer systems, Bitulen® 180 is available in talc finish.

    INSTALLATION

    Bitulen® 180 installation should follow recommended practices for torch-on membranes. Care must be taken when using Bitulen® 180 in close proximity to other combustible materials, decorative coatings and other heat sensitive materials.

    Install Bitulen® 180 by melting the heat dispersible film backing and coating with a high temperature flame 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 substrate or underlay. As the film and bitumen melt, roll the membrane forward allowing for side laps of 100 mm and end laps of 150 mm. A bead of bitumen must exude from all lap joints to ensure a uniform seal.
