Description
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.
Membrane composed of styrene-butadiene-styrene (SBS) modified bitumen with composite polyester reinforcement. The upper surface is finished with granules, with the selvedge protected by a polypropylene film. The lower surface is protected by a micro-perforated thermofusible film with a sand/ talcum finish.
Features and benefits:
- 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.
- BBA Certified Extensive Broof(t4) testing.
