EshaVent is a base sheet in 2 layer partially adhered systems. Consisting of an SBS modified bituminised fibreglass fleece, indirectly thermally activatable coating, perforated aluminium foil and removable film (patented) on the underside. Suitable for all types of roof with a flat or sloped roof construction on new build or refurbishment.
EshaVent is loose laid in accordance with the Radmat specification. Torching the top layer activates the partially applied EshaVent coating to allow it to bond to the substrate. When applying EshaVent on existing bituminous or sanded substrate the surface must be pre-coated with EshaPrimer.
