PRODUCT FUNCTION Sisalation®, when used in conjunction with an airspace, is a highly effective thermal insulating membrane due to the high reflectivity and low emissive properties of the aluminium foil surfaces. This combination makes Sisalation an excellent barrier to heat flow via radiation. When installed in industrial buildings as an exposed roof lining, the reflectivity of the foil will enhance the lighting of the building considerably.
Sisalation® FR430 is a heavy duty, double sided reflective foil laminate incorporating advanced fire retardant properties.
Category: double sided reinforced membrane.
