Reflectashield® reduces the thermal transmittance (U-value) of walls by introducing a reflective surface in the cavity between the frame and outer cladding, thereby inhibiting radiant heat transfer across the cavity. As the membrane’s breathability is not compromised by its thermal properties, Reflectashield® continues to act effectively to minimise the risk of condensation. Reflectashield® breather membranes help assist the diffusion of moisture from the building and reduce the condensation risk. Combining the proven benefits of a breather membrane and adding a low-emissivity reflective surface helps reduce heat loss through the cavity wall system.

Applications:
  • Protects timber and light gauge steel frames, SIPS and CLT Panels from wind driven rain, snow and dust during construction.
  • Assists with the controlled release of vapour from the structure.
Features & Benefits:
  • Reflectashield is a vapour permeable, low emissivity reflective membrane..
  • The Reflective face is specifically designed to enhance the thermal performance of the structure to which it is applied.
  • Excellent breathability minimises condensation risk and controls water vapour transfer.
  • Improves thermal performance.
  • Fabric Weight 134g/m2

Installation Guide:

  • Fix to frames using austenitic stainless steel nails or staples at centres not exceeding 500mm.
  • Install on the exterior of the structure.
  • Ensure the reflective, printed side is facing the cold outside.
  • Where the material is to be lapped, laps should be:
    – Vertical Laps – not less than 150mm.
    – Horizontal Laps – not less than 100mm.
  • Ensure integrity of Reflectashield by overlapping upper layers over lower layers and staggering vertical joints.
  • Overlap wall / sole plate with membrane and mark stud positions for wall fixings.
  • Penetrations and tears should be closed off using silver tape.
  • Tears greater than 25mm to be covered by Reflectashield patches with a min 100mm lap around the perimeter and well sealed with silver tape.
