Application

Suitable for use in new-build, renovation, refurbishment, extension or retrofit projects in pitched and flat roofs and walls. Can be used in external cladding projects.

Description

Combined breather membrane and multi-layer foil thermal insulation for roofs and walls, consisting of nine layers in total.

Features and benefits:

  • Acts as both foil insulation and a breather layer.
  • Can reach U-values of as low as 0.10 W/m²K.
  • Provides a radiant barrier - reflects excessive heat gain during the summer months, and insulates throughout cooler months.
  • The small footprint achieves a high thermal performance.
  • R-value of up to 2.22 m²K/W in pitched and flat roofs and 2.53 m²K/W in walls.
  • Helps to prevent the formation of mould and damp by reducing the risk of condensation.
  • Easy to install, and produces minimal waste.
  • Manufactured with 40% recycled materials and is recyclable at the end of its useful life.
  • Specifically designed using a reflective breathable membrane as the top layer to provide a secondary rain barrier and to allow moisture to escape. The below layers are then perforated to ensure that the entire product is breathable.
  • Can be used on its own, in multiple layers or with any other form of insulation to achieve any U-value.
  • CE marked, and manufactured in accordance with BS EN 13859.
  • Approved for Building Regulations by UK Certified Test laboratories - consult manufacturer for details.

Components:

  • Reflective coated breather membrane.
  • Three perforated aluminium coated, reflective foil polyethylene terephthalate (PET) layers.
  • Perforated, reinforced heavy outer reflective foil.
  • Four loft quilt layers, 80 g/m².

Applications:

Suitable for use in new-build, renovation, refurbishment, extension or retrofit projects in pitched and flat roofs and walls. Can be used in external cladding projects.
