Structural Insulated Panel System


The Kingspan TEK™ Building System is used to create high performance structural, super-insulated thermal building enclosures called Structural Insulated Panels (SIPS).

The system comprises 142mm or 172mm thick SIPS. Panel junctions can be detailed with a unique insulated SIPS spline jointing system to ensure minimal interruptions in the insulation layer.  Applications include; external walls, roofs, structural/non-structural infill.

SIPS can also be used to wrap over other structural framing systems - steel, concrete, oak etc.


The Kingspan TEK™ Building System SIPS are produced in a factory, non-weather dependant  environment using advanced, fully proven construction methods. Consistent, high quality manufacturing quality is assured in readiness for onsite work to commence with minimal risk of snagging issues to resolve. Suitable for a wide range of building applications, Kingspan TEK™ Building System SIPS are cost effective, make best use of space and are super-thermally efficient.  

Huge range of standard details with calculated low ψ psi values.
