Easy to install, lightweight, high performance aluminium bubble insulation membrane. Acts by trapping air within the bubble structure while creating low emissivity air spaces from foil-faced outer layers, enhancing overall thermal capabilities. Made with two layers of high-grade aluminium sheet for maximum thermal performance. Reduces the risk of condensation. Due to reflective cavities when in application, thermal resistance can increase to 1.465m²K/W. Aluminium & Plastic Construction Core Thermal Resistance up to 0.140m²K/W Thickness: 4mm Suitable for Walls, Roofs & Under Suspended Floors Equivalent to 55mm Polystyrene CFC/HCFC free Time-Saving Typically Used for New Builds, Refurbishment & to Insulate Behind Dry Lining Suitable For Domestic Use Reflective Cavities Increase Thermal Resistance up to 1.465m²K/W Aluminium & Plastic Construction Core Thermal Resistance up to 0.140m²K/W Thickness: 4mm Suitable for Walls, Roofs & Under Suspended Floors Equivalent to 55mm Polystyrene CFC...
