TradeSelect ThermalBreak 7
Flexible Reflective Insulation
Trade Select™ ThermalBreak 7™ is an Extra Heavy Duty three-in-one reflective insulation, thermal break and medium vapour barrier. 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 7™ is suitable for use in roof, wall and floor applications. Designed to manage heat gain and heat loss, Trade Select™ ThermalBreak 7™ offers superior thermal performance to conventional insulation, and reduces thermal bridging and conductivity between building elements.
The ThermalBreak 7™ 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 7™product the ideal choice for many applications.
Product Advantages
- The most cost effective R0.20 thermal break product in the Trade Select™ product range.
- 150 mm flap provided for increased coverage and reduced wastage.
- Contributes a reflective R-value when installed adjacent to an air cavity.
- Highly effective in dampening noise.
-
Water resistant, fire resistant.
- Fibre-free and non-allergenic.
- Rigorously tested by independent recognised accredited laboratories in compliance with AS/NZS 4859.1:2002/Amdt 1:2006 to ensure all product claims are met.

Installation Instructions
Trade Select™ ThermalBreak 7™ 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.
