Four hup! roof systems?

Quick & Easy Installation

hup! is provided as a flat packed kit, with parts cut to size. The Ultrapanel rapid connection technology ensures a quick build that can be watertight in 2-3 days.

Slim Construction

hup! walls are over 25% slimmer than brick and mortar, meaning the interior space will be 10-15% bigger. This in turn adds more overall value to the property.

Increase Turnover by 30%

Because hup! can be built with a small team in any weather in a fifth of the time, you can say goodbye to scheduling delays and increase turnover for your business.

What's in a hup! wall?

1 Internal Clips

Both our internal and external clips offer watertight fittings, keeping components securely in place. This feature also reduces drilling and makes hup! easier to install.

2 Wall Panels

hup! uses remarkably lightweight and thermally efficient materials, capable of achieving U-values of just 0.17 W/m²K with a width of just 215mm.

3 External Clips

Our external clips connect the wall panels and membrane, helping to drastically reduce installation time.

4 Membrane

A breathable membrane with clips for easy attachment is supplied with every hup! wall installation.

5 Battens

All clips and fixings are supplied to easily attach the membrane to the Ultrapanel's external clips.

6 Render Board

A pre-cut calcium silicate render board is fabricated to provide strength and longevity. This material is highly impact resistant, waterproof, fireproof, and provides excellent sound and thermal insulation.

7 Wall Finish

hup! is compatible with a wide range of wall finishes to provide complete design flexibility. Popular options include brick mesh, brick slips, timber and render.

8 Aperture Trim

Pre-cut aperture trims line the edges of all windows and doors, ensuring a neat and clean finish. These are available in white, grey, or any RAL colour.

9 Ventilation Trim

This trim runs along the top and bottom of the walling in order to prevent insect ingress or vermin.
