TradeSelect ThermalBreak 8

Flexible Reflective Insulation

Product Introduction

Trade Select™ Ametalin ThermalBreak 8™ is an Extra Heavy Duty three-in- one reflective insulation, thermal break and medium vapour barrier for use in all roof, wall and floor 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. Designed to manage heat gain and heat loss, Trade Select™ Ametalin ThermalBreak8™ offers superior thermal performance to conventional insulation, and reduces thermal bridging and conductivity between building elements.

The ThermalBreak 8 product is the highest rated product in the TradeSelect product range, achieving impressive thermal performance coupled with acoustic benefits. It has some of the highest reflectivity values on the market while retaining effective cost savings due to the additional overlap piece, making ThermalBreak 8 one of the premium products available.

Product Advantages

  • 150 mm flap provided for increased coverage and reduced wastage.
  • Made with high-density XPE foam; compression in-situ is minimised.
  • Contributes a reflective R-value when installed adjacent to an air cavity.
  • Highly effective in dampening noise.
  • Fibre-free and non-allergenic.
  • Water resistant, fire resistant.
  • 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™ Ametalin ThermalBreak 8™ 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, a 25 mm air space adjacent to each side of the product is recommended.
