These advanced panels not only streamline the build process but also deliver exceptional thermal efficiency. In fact, hup! extensions are up to five times more energy efficient than the average UK home.
While current Building Regulations require wall constructions to achieve a U-Value of 0.18 W/m²K, hup! walls exceed this standard with a U-Value of just 0.17 W/m²K, all within a remarkably slim profile of just 215mm in width.

hup! brick slip rails solution
The new hup! Brick Slip Rail System makes installing brick slips on hup! extensions quicker and easier than ever.
Compatible with all major brick slip brands, the system offers significant time savings on site — delivering installation speeds nearly twice as fast as traditional methods like gluing to calcium silicate boards.
hup! on dwarf walls
Save time, reduce costs, and simplify your build by specifying hup! on existing dwarf walls.
Whether you're replacing a window section with a small hup! wall or upgrading the full structure into a home extension, this option gives you greater flexibility - ideal for conservatory transformations on a budget.
Reusing existing walls means less demolition, fewer skips, and less disruption on site. Plus, homeowners can often keep their existing flooring - cutting thousands from the overall project cost.

Building Regulations
hup! walls exceed Building Regulations for thermal performance - without the bulk of traditional construction. To meet the required U-Value of 0.18 W/m²K using standard brick-and-block, wall thickness typically increases from 300mm to 350mm. In contrast, hup! walls achieve a superior U-Value of 0.17 W/m²K with a total thickness of just 215mm, helping to maximise internal floor space. For full compliance, the system also includes a drained and ventilated cavity behind the external calcium silicate board, providing a continuous 10mm ventilation gap in line with regulations.
