Ultra-double foil is a range of domestic and industrial products manufactured for all sectors of the construction industry that require reflective insulation foils for roofing and walling applications. These products are manufactured by laminating a nonwoven polypropylene membrane to highly reflective aluminium sheets, which create a technologically advanced product with high- performing physical properties. Ultra-double foil has the normal functions of technical roofing membranes, but also provide the added benefit of being a reflective insulation material which adds to indoor comfort and reduced energy consumption
