Kingspan TEK Building System


High performance structural insulated panels

The Kingspan TEK Building System is the premium product range within the Kingspan Timber Solutions portfolio. For Passivhaus performance this is the system we recommend. It is also possible to use TEK as a roof solution in conjunction with our ULTIMA wall system for room in the roof applications.


About Kingspan TEK

The system comprises an injected high performance rigid urethane insulation core, autohesively bonded to 15mm structural oriented strand board (OSB) on either side. The result is a very strong structural element with thermal performance built in. Durability and performance are independently assured as the Kingspan TEK® Building System is recognised by all the major building warranty providers such as NHBC, Building Life Plans and Premier Guarantee as well as holding BBA Certification.

The insulated spline jointing detail ensures minimal thermal bridging through the insulation layer and results in a very airtight building shell.

The system is consistent with our value creation ethos by promoting a number of key benefits including:

  • Exceptional thermal performance with wall and roof U-Values of 0.21 – 0.10 W/m2K with typical Y-Values ranging from 0.05 – 0.01
  • Highly airtight construction can achieve air permeability of less than 1 m3/hr.m2 at 50 Pa.
  • Panels are PEFC and FSC® (C109304) Chain of Custody certified
  • Zero ODP and low Global Warming Potential
  • Fast, cost effective and predictable
  • High dimensional accuracy and zero shrinkage
  • Accommodation of all types of external facades
  • Minimal site waste

Product Information

The Kingspan TEK building system benefits from large scale structural fire testing* and therefore the designer can specify the internal finish with confidence about Building Regulation compliance.
30 minutes REI performance is easily achieved with only a single layer of 12.5mm standard plasterboard fixed in accordance with the manufacturer’s instructions. 60 minutes fire resistance is achieved with a single layer of 12.5mm fire resistant board.

*Fire test undertaken by Exova UK Ltd in accordance with BS EN 1365-1: 1999 – Read technical note here
The proprietary jointing system used with the Kingspan TEK® Building System creates an incredibly airtight structure which can achieve Passivhaus levels of 0.6 ach @ 50 Pa if so desired. Standard construction usually results in performance of circa 1.0 m3/hr.m2 @ 50 Pa.

At this level of airtightness we recommend the inclusion of MEV or MVHR air handling as window vents are insufficient for Approved Document Part F.

Based on brick cladding a wall based on our 142mm TEK panel achieves 0.19 W/m2.K or 0.16 W/m2.K with a 172mm panel without additional Kooltherm lining. For other U values we add an internal Kooltherm lining behind the service batten. For Passivhaus we recommend the use of Kooltherm externally to wrap the structure. We will assist your Architect in the development of an appropriate wall specification including condensation risk analysis free of charge as part of our Customer technical support.
