Firetite Cavity Wall Insulation

Research indicates that over 30% of heating is lost through the walls of your home and that Cavity Wall Insulation can help prevent these losses.

Firetite Cavity Wall Insulation

FIRETITE is a limited combustibility class A2 fire rated, mineral based injection insulation material ideal for new and refurbished cavity wall insulation. This innovative system combines the benefits of a hydrophobic and open-pore mineral insulation material with the fast, safe and seamless airtight process of a self sealing foam system.

FIRETITE is the world’s first 3-component mineral based in-situ insulation material. It has been developed over many years of extensive research to create this unique formulation.


  • Non-flammable – FIRETITE insulation consists of 90% inorganic minerals and 10% organic components and is classified as a limited combustibility A2-s1,d0 construction material suitable for high rise buildings above 18m. FIRETITE achieves a smoke propagation indicator of s1 and a d0 rating for non-flaming droplets or particles as part of the overall A2 classification.
  • Insulation – FIRETITE has a rated thermal conductivity value of 0.034W/mK.
  • Waterproof – FIRETITE is water repellent.
  • Quick and easy to install – FIRETITE is installed by trainedoperatives from the exterior of the building at a rate of approximately 100m2 per day. The product is suitable for new build or refurbishment cavity walls where the wall is open to diffusion.
  • Breathable – FIRETITE is open-pored structure allows water vapour to evaporate. The product also has a certain capacity to store vapour, thereby regulating moisture in the surrounding area helping contribute to better indoor climate.
  • Harmless – FIRETITE is a mechanically blown foam with pressurized air, meaning the foam does not contain internal propellants which might otherwise cause internal pressure built up. It does not emit pollutants – neither while drying or while the foam remains in the hollow layer. FIRETITE achieves the best EMICODE emission classification of EC1 plus.
  • Sustainable – FIRETITE is produced and installed using components which use very low energy. Waste material can be disposed of with construction waste. FIRETITE has a very low carbon footprint determined within the Environmental Product Declaration (EPDBAS- 20180124-IBA1-EN).
  • Space saving – The mixing process results in a finished FIRETITE product that is up to 10 times it’s original liquid volume, saving on transportation and storage. The product is fully expanded before injected into the cavity and does not cause any internal pressure on the cavity.
