The active phase of construction began a while ago. The demand for SIP houses is constantly growing. So far, we can talk about the accumulated experience and useful life, which is at least 100 years. A striking example is the US cottages. They were built more than 50 years ago. However, they have perfectly preserved their appearance and all performance characteristics.
The long service life of houses is due to the durability of building materials. The main component, which is expanded polystyrene, does not lose its technical performance and heat-insulating properties even after 60-70 years of use.
