Kingspan ULTIMA Timber Frame Build System

Kingspan ULTIMA is our closed panel timber frame offering, manufactured in our quality controlled factory to guarantee dimensional accuracy. We offer Kingspan ULTIMA in two different options, the only difference being the degree of insulation they provide, and their U-values lie between 0.15-0.13 W/m²K depending on your thermal efficiency needs and your external cladding.

Benefits of Kingspan ULTIMA for self build

Improved Health and Safety

As less time is spent on-site thanks to large scale construction elements being delivered from the factory.


Where Kingspan ULTIMA panels join other elements the jointing detail helps to achieve the required level of airtightness.

Fire Performance

Kingspan ULTIMA exceeds Building Regulations requirements for fire resistance performance. The system benefits from fire resistance testing carried out to BS EN 1365-1: 2012.

Accurate Build Schedule

As timber frame construction is a dry method of construction, adverse weather has a reduced impact on the speed of work on-site, helping you stay on schedule and plan with confidence.

Reduce Cost

Lower on-site labour costs as reduced work is required on-site. As panels are manufactured in a quality controlled environment less waste is produced on site. Waste can be costly to dispose of.

Slim Wall Build-up

Giving you more internal floor area and potentially increasing the value of your home.
