hup! wall system

hup! walls - a building revolution

hup! walls, when combined with the choice of one of five different roofing systems, delivers a lightweight yet robust structural solution which can be built and made watertight in a fraction of the time it takes to build the equivalent structure using standard construction methods.

hup! uses highly energy efficient Ultrapanels in place of traditional brick walls and timber and slate roofs. These groundbreaking panels make hup! extensions five times more energy efficient than the average UK home.

New Building Regulations specify that walls should have a U-Value of 0.18W/m²K, hup! walls achieve a U-Value of 0.17W/m²K and have a width of only 215mm.

Wall kits - what's supplied?

The hup! wall kit consists of everything you need to get your hup! building watertight.

  • 1 Internal Clips
  • 2 Wall Panels
  • 3 External Clips
  • 4 Membrane (including clips)
  • 5 Battens (including fixings)
  • 6 Render Board
  • 7 Wall Finish
  • 8 Aperture Trim (White, Grey, any RAL colour)
  • 9 Ventilation Trim

Ventilation trim

To prevent vermin or insect ingress and other debris, the wall finish is supplied with a ventilation trim that runs around the perimeter of the build at the top and bottom of the walling.

The ventilation trim can be ordered separately if using your own wall finishes or it is supplied with timber battens, render board, or brick mesh wall kits.

Aperture trim

The aperture trim is an easy way to finish off the hup! Brick Mesh at the windows and doors. Supplied cut to size and can be ordered in any RAL colour to match your window and door frames or wall finish.

Supplied as standard with the Brick Mesh and render board, but if you are using your own wall finish you can order the trim separately.

Building Regulations

Building Regulations specify that walls should have a U-Value of 0.18W/m²K. To achieve this U-Value in traditional brick and block construction, the width of the cavity wall will increase from 300mm to 350mm and this is increased further with the addition of dot and dab plasterboard on the inside.

hup! walls achieve a U-Value of 0.17W/m²K and only has a width of 215mm resulting in additional internal floor space.

To comply with Building Regulations, hup! also has a drained and ventilated air gap behind the external calcium silicate board allowing for 10mm continuous ventilation.
