Save up to 10% internal floor space by switching
SureCav can provide the difference between you wasting internal floor space or gaining it! By choosing SureCav over the traditional concrete backing blocks saves you 125mm wall width on every external wall width and increases your internal floor space by up to 10%
Since the new regs, SureCav has proven to be the popular choice in brick builds, achieving the 0.18 regs, keeping 100mm cavities. When compared to the misleading guidance of 150-200mm cavities, you keep 100mm cavities and save up to 2.6-5.2m2 internal floor space alone, but also providing a better-quality end product also!
When you switch the backing blocks for SureCav you can easily save up to 10% internal floor space. In a stone/flint build a backing blocks is installed to keep a dry, clear cavity and provide a backing for the stonework. The SureCav provides the backing, whilst keeping a clear, dry, vented cavity and adds a wall of protection against wind-driven rain and saving the space!
