Insulation Products


Effective non-combustible thermal and acoustic insulation for ventilated façades. RAINSCREEN DUO SLAB is a dual-density insulation specifically developed for use within ventilated cladding systems, as well as sealed systems such as curtain walling. Once installed, the robust outer surface of the slabs, in combination with a factory- applied water repelling agent, acts to resist rain ingress during construction.


  • A1 Non-combustible
  • Designed for use on high rise buildings
  • Water-repellent: Fibres impregnated with a water- repelling agent during manufacture
  • Fewer fixings required for installation compared to standard stone wool slabs
  • Robust front face resists damage and over-driving of fixings

Earthwool RainScreen Slab

Earthwool RainScreen Slabs are non-combustible Rock Mineral Wool slabs, manufactured using our revolutionary ECOSE® Technology and a water repellent additive, and are designed for use in rainscreen façade systems both below and above 18m in height.

  • Excellent thermal performance.
  • Non-combustible A1 Euroclass Reaction to Fire classification
  • Excellent sound absorption characteristics provide high levels of sound reduction
  • Suitable for use on all buildings including those above 18m in height providing compliance with fire related building regulations.
  • Contributes to building regulation compliance without reliance on separate testing or desktop studies.
  • Provides a unique combination of thermal, fire and acoustic performance.
  • Can be installed either way round on site without compromising performance.
  • 3D U-value calculations
  • Wind load testing
  • Water repellent additive
  • More robust slab
  • Improved mechanical characteristics
  • Enhanced thickness range 50-250mm


The self-adhered nature of Wraptite allows for a simple and fast installation process, minimising the use of additional sealants and tapes, and requiring no specialist contractors to achieve a robust result.This one-step solution provides both a damage resistant air barrier layer and effective secondary weather protection in one installation process, allowing a wind and watertight envelope to be achieve more quickly than using traditional methods.

  • Airtight yet vapour permeable
  • BBA Certified (Cert. No. 15/5274)
  • Tough 3-Layer Laminate resists punctures and tears
  • Lightweight and easy to install
  • Wide service temperature range
  • Can be left exposed for up to 90 days (North America) or 120 days (UK) during construction
  • Free from Volatile Organic Compounds
