Low resistance vapour permeable breathable roofing membrane which is a composite structure, manufactured via lamination of a water vapour permeable film between two layers of nonwoven polypropylene spunbond to form a flexible, vapour permeable roof tile underlay. This allows for the ready transfer of moisture through the underlay, thereby reducing the risk of condensation in the roof structure. Suitable for cold and warm pitched roofs and fully supported and unsupported roofing applications it can be used in conventional ventilated roof construction providing that the membranes is installed in accordance with the relevant certification.

It is made of two layers of air bubble polythylene, wedge-welded for a width of 15mm and covered by a film of low emission aluminium on both sides. The materials used to make AlumTech are absolutely safe, non-toxic and non-harmful. Reflective thermal insulation blocks up to 97% of the radiant heat transfer across thin open spaces whatever the humidity, which prevents heat gain in summer and heat loss in winter, in addition aluminium foil creates an effective barrier against moisture and air flow, in addition to being a reflective material and is a permanent way to reduce your energy bills which can be over 30% repaying initial installation costs in no time.
