Installation Instructions

Trade Select™ ThermalBreak Strips are typically installed to the exterior side of the structural framing building envelope after installing the of the pliable building membrane. It is recommended to install Trade Select™ ThermalBreak™” Strips at the same time as the outer cladding; this will ensure optimal durability and performance.

  1. Pliable building membrane is installed to the roof or wall steel frame construction in accordance with AS 4200.2:2017.
  2. Locate the structural members to which the Trade Select™ ThermalBreak™ Strip is to be applied. eg: studs, plates, rafters, purlins etc.
  3. Ensure that the surfaces to be adhered to are clean, dry and free from dirt, grease, oil and other contaminants.
  4. Peel back the release liner from both sides of the folded strip.
  5. Centre the Trade Select™ ThermalBreak™ Strip parallel to the supporting framing member.
  6. Apply the strip, ensuring maximum surface contact is achieved by applying firm pressure by hand or roller applicator.
  7. Install cladding or roofing materials without delay.
