Many UK homes — particularly older properties with solid walls — lose heat easily and are more vulnerable to damp, condensation, and mould due to the lack of cavity insulation.
TIWI SprayCork is a natural cork-based coating that creates a breathable insulation layer on internal or external walls. Once applied, it helps regulate temperature, reduce heat loss, and improve overall energy efficiency.
Unlike traditional insulation systems, TIWI SprayCork controls condensation without sealing in moisture. This means warmer walls, fewer cold spots, and a healthier indoor environment — all while maintaining valuable living space and protecting the fabric of the building.
At just 6–8mm thick (including overskim), TIWI SprayCork is ideal for homes where traditional insulation systems would take up too much valuable space.
With a thermal conductivity of 0.058 W/mK, SprayCork helps eliminate thermal bridges, retain heat, and improve overall energy efficiency.
Made from natural cork, the coating remains breathable and flexible, helping to manage moisture while reducing the risk of shrinkage cracks.
Suitable for internal and external use, TIWI SprayCork forms a long-lasting protective coating and comes with a 10-year manufacturer’s warranty.
