High Performance

The Guardian extension utilises the Kingspan TEK® Building System, which has a superior U-value of just 0.16 W/m2.K with a total wall thickness of 275.5 mm. To achieve an equivalent U-value using traditional methods of construction the wall would have to be 453 mm thick.

Most of the construction work is done off-site meaning the complete system is delivered to site ready for installation. The final extension is completed in a fraction of the ‘on-site’ time and at a lower cost than a brick and block built alternative.

Each building is designed and constructed on a bespoke basis to your exact specification.

Thermal Efficient
