Structural insulated panels (SIPs) are high performance building panels used in floors, walls, and roofs for residential and light commercial buildings. The panels are typically made by sandwiching a core of rigid foam plastic insulation between two structural skins of oriented strand board (OSB) to produce a rigid structure.

This type of technology is available with all Nest & Invest houses.
We are able to source and incorporate this at the time during the design.

Many different types of SIPS structures are possible, which are fundamentally based on the same materials and design goals. An insulation material is sandwiched between two flat OSBs. The inside of these panels will have any number of timber frames to provide the strength to the wall panel. In some cases, several sandwich layers are used like a double or triple deck sandwich. This allows features like wind proof sheeting to be inserted to further reduce heat loss from convection as well and conduction.

There is a wide variety of hybrids compositions that can be used to improve the strength and insulation properties of the SIPS panels. Some manufacturers apply a layer of polystyrene to the outer wall that is re-enforced with a re-enforced mesh to provide a water tight and re-enforced outer layer. Finally customers can apply a cosmetic outer layer which can be wood cladding as is popular in Scandinavia, or rendering, or brick facing which are popular in the in UK.

The main advantage of SIPS over traditional build is not only due to being ecologically friendly, it is that entire wall panels can be prefabricated and put up. Houses built from SIPS often go up and are water tight in 2 days, and can be fully finished in less than 10 working days.
