What Are SIP Building Kits?

SIP building kits are pre-designed structural systems made from structural insulated panels, combining strength, insulation and airtightness in a single solution.

Our SIP kits are supplied ready for assembly, reducing on-site build time while delivering outstanding energy efficiency and long-term durability. They are suitable for both domestic and light commercial projects.
