TradeSelect ThermalBreak™

Flexible Reflective Insulation

Trade Select™ ThermalBreak™ is an Extra Heavy Duty three-in-one reflective insulation, thermal break and Class 2 Vapour Barrier for use in all roof and wall types. It meets the NCC/BCA requirements for in-situ material R-value of R0.2 for a thermal break in steel framed construction, and is also suitable for use in timber framed construction. Trade Select™ ThermalBreak™ is suitable for use in roof, wall and floor applications. Designed to manage heat gain and heat loss, Trade Select™ ThermalBreak™ offers superior thermal performance to conventional insulation, and reduces thermal bridging and conductivity between building elements.

The Trade Select™ ThermalBreak™ product is the all-round solution designed for walls, roofs, sheds and underfloor applications. An overlap piece to provide full roll coverage rounds off the list of features, making the ThermalBreak™ product the ideal choice for many applications.

Installation Instructions
Trade Select™ ThermalBreak™ is not designed to withstand prolonged direct exposure to the elements. Accordingly, the outer construction envelope should be installed without delay. Aluminium foil should not come into contact with wet concrete or mortar, as the aluminium is susceptible to alkali corrosion. If installed within 500 metres of the sea, or in a non-residential building where foil surfaces may be exposed to a corrosive atmosphere (including agricultural sheds), foil surfaces should face an enclosed, un-vented air space. To ensure optimum thermal insulation performance, as well as satisfactory durability, an air space adjacent to each side of the product is recommended.
