Structural Insulated Panels (SIPs) by Kingspan TEK

By now you’ve probably heard about SIPs, and the advantages of building with SIPs by why Kingspan TEK?

The Kingspan TEK Building System is based on structural insulated panels (SIPs). These 142 mm or 172 mm thick panels comprise high performance fibre–free rigid urethane insulation sandwiched between two sheets of 15 mm Oriented Strand Board type 3 (OSB/3).

The panels can be up to 1.22 m wide, up to 7.45 m long and are very strong. The panels are joined together using a unique insulated jointing system that minimises air leakage.

In addition, the design of the joints yields a more continuous layer of insulation in your walls and roof. To illustrate this point, in a property constructed with traditional timber frame, the repeating thermal bridges caused by timber studs in the walls, and rafters in the roof, means that you could typically expect 15% of the walls and 9% of the pitched roof to be uninsulated.

By comparison, in a property constructed using the Kingspan TEK Building System (in a 142 mm thickness), as little as 4% of the walls and 1% of the roof may be uninsulated. The overall thermal performance of the Kingspan TEK Building System, which is provided by a combination of the high performance insulation core of the panels, air tightness, and low thermal bridging, can mean that a home’s heating system may be able
to be ‘down–sized’ considerably, which could save on both capital and running costs.

In fact, the Kingspan TEK Building System is the perfect high performance building fabric solution for extremely low energy buildings which require little or no heating at all, such as those designed to Passivhaus standard. The Kingspan TEK Building System has been used as an integral component in delivering a number of certified Passivhaus projects.

Ventilation is an integral part of any airtight home. A mechanical ventilation with heat recovery (MVHR) system is recommended for properties constructed using the Kingspan TEK Building System. In short, MVHR systems extract the moist waste air from your home and replace it with fresh air from outside. Integral to MVHR systems is a heat exchanger, which will extract the heat from the outgoing waste air to heat the incoming air. Recovering this heat can provide a large proportion of the heat required to keep a home at comfortable living temperatures.

The Kingspan TEK Building System is also typically very quick to build, particularly if you are also constructing the roof from Kingspan TEK® Building System panels. The panels can be joined together and erected very quickly and, with the application of a breather membrane, the System forms a weather tight shell, enabling you to start the follow on trades such as plumbing and electrics at the same time as tiling the roof.

More detailed information, about the design and performance characteristics of the Kingspan TEK Building System, is given in the Kingspan TEK® Building System Specification Manual, which is available for download from the Kingspan TEK website.
