Demand for SIPs has made a qualitative leap because of the development of the timber framework. Vendors started looking for multipurpose construction material. SIPs perfectly fit its criteria.
SIP is a multilayer panel that has got an interstitial layer of thermal insulation and external layers in the form of OSB sheets. The panels are made through agglutination of separate layers with polyurethane adhesive and further pressing under a pressure of 18 t. OSB has several layers of wood chips, the binding component is resin. The material is highly competitive with particle boards in the realm of durability, and it gradually puts them out of the market. The main advantages are firmness and elasticity. The light foam plastic is used as an insulation material. It's also known under the name "foam polystyrene". It has obtained high thermal insulation properties due to the "bubbles" of air that make up the structure of the material.
Houses, constructed with the help of SIPs, are often called "Canadian". They protect well from the cold and are resistant to the northern winds. The history of construction began more than 10 years ago, and technologies are always being improved. Anyway, lots of master-builders take them with a grain of salt. The main repellent is external material fragility. Confidence in brick is still higher, although it is far from being an ideal construction material.
Attitudes to SIPs are very different in Europe and America. There work hundreds of unconstrained organizations that help everyone to master the intricacies of the construction craft with the help of SIP panels.
