Structural Insulated Panels (SIPs) | Kingspan TEK

Kingspan TEK™ is our structural insulated panel (SIPs) offering. Kingspan TEK™ is composed of two sheets of oriented strand board (OSB) sandwiching a rigid, high-performance core of phenolic urethane with excellent insulative properties. Achieving excellent airtightness levels with virtually no thermal bridging, Kingspan TEK™ is perfect for those who want a rapid build time and exceptional thermal performance.

Kingspan TEK™ Information

Kingspan Kooltherm
Thermal Bridging
Fire Performance
Kingspan TEK™ comprises two sheets of OSB sandwiching a high-performance, rigid urethane insulation core. Our unique insulated jointing system creates an airtight structure with the capacity to reach Passivhaus standards of performance (less than 0.6 ach @ 50 Pa). For most buildings, a performance of 3.0 m³/m²/hr @ 50 Pa can be easily attained.
The thermal efficiency of Kingspan TEK™ is only increased with the addition of a layer of Kingspan Kooltherm insulation, a market-leading phenolic insulation. This can be added as an internal lining behind the service batten and even as an external wrap around the structure for very low-energy buildings.
The unique jointing system means the system is not interrupted by repeated studwork, minimising heat loss through thermal bridging, improving the building’s overall energy efficiency. Measurements of 0.03-0.04 are achievable.
The Kingspan TEK™ build system benefits from intensive structural fire testing and comfortably surpasses the requirements of Building Regulations. For most detached residential properties, the level of protection required can be achieved with just a single layer of 12.5mm plasterboard. An hour of fire resistance, if required, can be achieved with a single layer of 12.5mm fire-resistant board.
