01795 515 110 Website

Application

  • Suitable for use as an insulating breather membrane.
  • Suitable for use below tiles and cladding.

Description

An insulated roof and wall underlay membrane that is airtight and ventilated. When used in conjunction with standard insulation products, the product enhances U-values 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.


Features and benefits:

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