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! 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.

hup! wall finishes
hup! is compatible with any wall finish to provide design flexibility. Some common exterior wall finishes include brick mesh, brick slips, timber claddings and contemporary cement boards.
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.
Any questions?
Is it possible to put hup! onto an existing wall?
Yes it is. Whether you want to just replace one or two windows with a hup! wall or add hup! to existing walls to create a completely new look, hup! can easily cope. You can choose between having a cill between the dwarf wall and the hup! wall and having a different wall finishes on the hup! or you can choose the full cladding option where the wall finish can run the entire height of the building for a more premium look. hup! works on both 250mm and 300m walls -the width of the existing wall must be specified at the time of order. If Building Regulations are required, you will need to bring the entire wall to 0.18 UValue.
What is the loading of the hup! wall on the base?
0.4 kilonewtons per meter squared.
What fixing do I use to secure the base tray?
Any suitable fixing (for the substrate) with at least a 1 kilonewton pull-out force. You need to put fixings in every pre-punched hole, which are set at a minimum of 600mm.
How are electrics installed with hup! walls?
Cable management panels can be specified beforehand to incorporate a trunking system at 450mm height, allowing the electrician to easily run cables along the wall to the desired locations. If running up the wall, the cable should run in a flexible conduit to separate it from the EPS insulation.
Can I put radiators on the hup! wall?
Yes you can - ensure you use suitable fixings for dry wall anchoring such as Grip-it, or Bullfix heavy-duty dry wall anchor.
