Kingspan TEK® – SIPs (Structural Insulated Panel) Building System

The Kingspan TEK® Building System is based on structural insulated panels (SIPs), comprising a core of high performance rigid insulation sandwiched between two sheets of 15 mm Oriented Strand Board (OSB).


The Kingspan TEK® panels comprises 142mm or 172mm thick structural insulated panels and are joined together using a unique insulated jointing system that minimises air leakage and the system is not interrupted by repeating studwork, minimising heat loss through thermal bridging.
