FIRETITE® Class A Fire Rated Insulation

FIRETITE is a limited combustibility class A2 fire rated, mineral clay insulation ideal for new and refurbished cavity walls. 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 clay mineral based in-situ insulation. It has been developed over many years of extensive research to create this unique formulation.

Firetite Class A fire-rated foam insulation


Firetite benefits – 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.

Firetite benefits – Insulation


FIRETITE has a rated thermal conductivity value of 0.034W/mK.

Firetite benefits – waterproof


FIRETITE is water repellent.

Firetite benefits – breathable


Its 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.

Firetite benefits – Installation


The product is suitable for new build or refurbishment cavity walls where wall construction is open to vapour diffusion. 

Firetite benefits – Adhesive


FIRETITE is a self-sealing product and sets immediately after application, adhering to both itself and the masonry cavity walls. The flow properties of the product ensures it fills the cavity seamlessly.

Firetite benefits – 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.

Firetite benefits – Sustainable


The production and installation of components uses very low energy. Waste material can be disposed with construction waste. FIRETITE has a very low carbon footprint determined within the Environmental Product Declaration (EPDBAS- 20180124-IBA1-EN).

Firetite benefits – Space saving

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.

Firetite benefits – Water based

Water based

The system is solely water based. While drying the pores open and the foam is open for diffusion.

Firetite benefits – Easy to install

Quick and easy to install

FIRTITE is installed by trained contracting crews from the exterior of the building at a rate of approximately 100m2 per day.
