Eliminate Black Spot Mould

As a natural product, SprayCork is breathable and has great thermal properties. SprayCork 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 SprayCork 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 SprayCork has been installed to the substrate, we can then install a finish plaster with the final total thickness of our system being only 6-8mm. Unlike other methods of insulation (IWI) due to the thickness there is no requirement to replace light switches, skirting boards, architraves, coving or windowsills.

SprayCork is breathable, fire retardant euro class B, extremely flexible, a strong thermal insulator and acoustic insulator. For your total peace of mind, it also comes with a 25 year product guarantee.
Benefit from cost savings from lower energy bills without eating away at your living space.
