Description

Insulated roof and wall underlay membrane that is airtight and ventilated. Aluthermo RoofReflex® can be used in conjunction with standard insulation products to enhance the achieved U-value of any installation, through an integrated insulation layer that is laminated to a high emissivity surface.

Manufactured using hydrophobic and self-extinguishing polyester fibre, created from recycled material. Aluthermo RoofReflex® has integrated sealing tapes to quickly and easily maintain the airtight seal at all joints. Suitable for use below tiles and cladding.

Features:

  • Low emissivity external face.
  • Improved acoustic values.
  • Reduces thermal bridge losses.
  • Fully airtight when installed with the supplied integral tapes.
  • Reduces overheating in summer by providing a cooling effect and lowering air-conditioning costs.
  • Adds up to 1.47 m²K/W in thermal resistance (R-value).
  • Hybrid roof and wall membrane combined with an insulation layer.
  • Lower installation costs than PIR systems.
  • EPC-approved and LABC-approved.
  • CE-marked to EN 13859-1 and -2.
  • Ten-year warranty.
