Eco-friendly Structured Insulated Panels (SIPs) offer a strong structure and fantastic thermal insulation.
Our garden rooms are created using Structural Insulated Panels (SIPs), which make for an incredibly strong and energy-efficient space. Made from a layer of polyurethane sandwiched foam between two sheets of Oriented Strand Board (OSB), they offer an amazing thermal insulation of c.0.27 for a 97mm thick panel and c.0.21 for a 122mm thick panel.
They are made using Envirofoam 16.464, which contains no CFCs or HCFCs (gases harmful to the ozone layer). Envirofoam is instead created using polyols derived from a natural vegetable origin, making it a great eco-friendly alternative.
The Oriented Strand Board also offers good environmental credentials compared with other plywood sheets.
