BBA Agrément Certificate
Certificate type
Membrane with a vapour-pressure and tension dispersion system, composed of a double bitumen coating with fire-retardant additives and a composite polyester reinforcement.
Suitable for use in waterproofing in roofing.
The plastomer modified bitumen (TPO) upper side has a high mechanical resistance and is UV-resistant while the elastomer modified bitumen lower side and the overlap ensures good adhesion. Used as a single layer waterproofing system on surfaces where fire retardant properties and partial adhesion are required. The upper surface is finished with granules and the overlap is protected by a thermofusible film. The lower surface is provided with thermofusible bitumen stripes alternated with non-stick stripes protected by a thermofusible film.
