Application
For exposed roofs with a concrete substrate. For other uses and substrates, including use under a green roof, please see other listings or contact Soprema UK.
Description
A warm roof system with a cap sheet composed of styrene-butadiene-styrene (SBS) modified bitumen with composite polyester reinforcement. The upper surface is finished with granules and the overlap is protected by a thermofusible film. The lower surface is protected by macro-perforated thermofusible film and talcum/sand for use within a single or multi layer waterproofing system.
An underlayer with a vapour-pressure and tension dispersion system, composed of elastomer-modified bitumen and a composite polyester reinforcement. PIR insulation faced with a polypropylene fleece-finished bitumen glass working surface and a mineral glass facing to the under side and a self-adhesive AVCL applied to a primed deck.
Features and benefits:
- BROOF (t4).
- Good cold bend resistance.
- Can be installed at very low temperatures.
- High puncture resistance.
- Long life expectancy.
- Laps may be hot air welded.
- CE marked to BS EN 13707.
