ISOLMANT POLIMURO REFLEX
Cross-linked polyethylene thermal insulation felt
Aluminium, Polyester fibre, Cross-linked polyethylene (PEX)
Low thickness radiant barrier featured by high thermal and acoustic performance. It is made of two layers of Isolmant 5 mm coated by a pure aluminium foil with an interposed layer of FIBTEC XS4 polyester fibre.
Isolmant Polimuro Reflex is a radiant barrier , featured by high thermal and acoustic performances. It is recommended for small size cavities (4-5 cm). The pure aluminium sheet provides a perfect vapour resistant barrier and thanks to its low emissivity rate, it also ensures high reflectivity and radiant heat gain (ε = 0.04). The thermal resistance improvement given by the reflective system is optimised if the product is interposed between two vertical air gaps of 20 mm thickness (horizontal thermal flux). In order to realize the double air gap, it is recommended to fix sheets of Polimuro Reflex with mechanical fasteners or metal staplers on 2 cm wood battens previously nailed on the existing wall. Install Isolmant Polimuro Reflex by laying the sheets side by side and then sealing them by means of Isolmant Alluminio tape. When realising the second wall, please keep a 2 cm air cavity to allow the proper operation of this thermo-reflecting material.
