+44 (0)1636 639900 www.superfoil.co.uk
Application

Suitable for use in new-build and retrofit projects in roofs, walls, under floors and in other areas of construction where required. Particularly for use in specialist projects that require walls and roof structures to meet specific fire rating requirements.

Description

Non-combustible multi-layer foil thermal insulation for under floors and walls, consisting of three layers in total.

Features and benefits:

  • Acts as both a foil insulation and vapour control 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.
  • R-value of up to 1.54 m²K/W in pitched roofs and 1.99 m²K/W in walls.
  • Non-combustible, and will not ignite or burn.
  • The small footprint achieves a high thermal performance.
  • Easy to install, and produces minimal waste.
  • Manufactured with 40% recycled materials and is recyclable at the end of its useful life.
  • Combi installation methods allow use with any other form of insulation to gain the required performance. Duet installation consists of an over and under the rafter application for a higher performance.
  • CE marked, and manufactured in accordance with BS EN 13859.
  • Approved for Building Regulations by UK Certified Test laboratories - consult manufacturer for details.
  • BRE certified.
  • Has a life expectancy of over 50 years.

Components:

  • Two layers of glass fibre reinforced, heavy duty laminated aluminium foil.
  • One high density E glass fibre matte.

Applications:

Suitable for use in new-build and retrofit projects in roofs, walls, under floors and in other areas of construction where required. Particularly for use in specialist projects that require walls and roof structures to meet specific fire rating requirements.
