Eurocell, the leading manufacturer and distributor of PVCu building products, has introduced its advanced 150mm Cavalok cavity closer system, this evolved design builds on the original 150mm system to support housebuilders as they embrace the “fabric first” approach amid a growing demand towards wider cavities.
A new survey from Professional Builder and Knauf Insulation has revealed that 150mm cavities are fast becoming the preferred choice for housebuilders in the UK, with 41% of participants already implementing the wider cavity approach in new builds and over a quarter considering it for upcoming projects.
Eurocell’s investment in 150mm Cavalok cavity closers is directly aligned with this industry shift, allowing builders to meet and exceed future carbon reduction targets through improved thermal performance. This wider cavity system supports reduced heat loss – one of the largest sources of energy inefficiency in homes.
150mm cavities play a crucial role in the “fabric first” approach by significantly increasing a building’s insulation capacity, allowing housebuilders to achieve greater energy efficiency through the structure itself. This strategy enables housebuilders to meet the 31% carbon reduction targets of Part L21 and prepares them for the 75% reduction target anticipated with Part L25. By enhancing U-values with thicker, well-insulated walls, heat loss can be reduced by up to 35% through walls alone, minimising the reliance on additional renewable technologies.
Martin Benn, Eurocell’s Head of New Build, explains; “Wider cavities allow builders to rely less on renewables – such as PV panels – and instead offer a permanent, cost-effective energy-saving solution embedded into the structure for the lifespan of the building. This approach aligns with housebuilders’ preference for low-maintenance solutions and reduces homeowners’ long-term energy costs.”
By focusing on sustainable product innovations like the 150mm Cavalok cavity closer, Eurocell is equipping housebuilders with the tools they need to deliver homes that are efficient and in line with the UK’s carbon reduction targets.
