Eliminate Black Spot Mould
As a natural product, Cork Spray is breathable and has great thermal properties. Cork Spray can lower heat emissions through solid walls by up to 30% and when working alongside a ventilation calculation, it can cure black spot mould for good.
One of the key benefits of Cork Spray is how thin it is, therefore saving space and disruption inside the home or building while delivering strong values in thermal correction, stopping the dew point which black spot mould requires to grow. Once Cork Spray has been installed to the substrate, we can then install a finish plaster with the final total thickness being on average 6mm. Unlike other methods of insulation (IWI) due to the thickness there is no requirement to replace light switches, skirting boards, architraves, coving or windowsills, lowering labour costs.
Cork Spray is breathable, fire retardant euro class B, extremely flexible, a strong thermal insulator and acoustic insulator.

Eliminating the dew point
Cork Spray will terminate the dew point on the substrate, correcting the thermal bridge.
Lower heating bills
Your Cork Spray coating will reduce heat loss by up to 30%, bringing significant savings on your energy costs.
Acoustic insulation
Acoustic insulation goes hand in hand with thermal insulation. Cork Spray can absorb up to 38dB of noise.
Cost effective
Cork Spray coating is a cost-effective solution, when compared to long labour-intensive methods.
Environmentally friendly
Cork Spray is a breathable system and doesn’t contain any nasty chemicals, making it hypoallergenic.
100% sustainable and carbon negative
Because the tree bark grows back on cork oak in around 9 years, it’s a truly a 100% sustainable product.
