Benefits of Kingspan TEK® 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.


The Kingspan TEK® system has been engineered to achieve levels of airtightness that can help your home reach the Passivhaus Standard.

Fire Performance

The Kingspan TEK building system benefits from fire resistance testing carried out to BS EN 1365-1.

Accurate Build Schedule

As SIPs are a dry method of construction, adverse weather has little effect 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.

Rapid Build Times

As Kingspan TEK® is a SIP, it is fabricated in a factory and then delivered to site, ensuring a faster and safer build.

Design Flexibility

SIPs are normally used for external walls and roof structures. Panellised roof structures remove the need for trusses and can simplify the construction of ‘room in the roof’ solutions.

Thermal Efficiency

Kingspan TEK® creates houses with strong energy efficiency credentials saving you money on energy bills and reducing your carbon footprint.
