Structural insulated panels (SIPs) are engineered, load-carrying,
timber-based panel products that can be used in walls and roofs of residential and light commercial buildings. These lightweight panels combine the
structural and thermal envelope of the building; they are manufactured
off site in Holmes factory and shipped to the construction site,
offering advantages to the build programme. This panelised form of
construction allows SIPs to be assembled to form highly airtight,
energy-efficient building envelopes.
