What is a SIP?
A structural insulated panel is a factory-made panel that combines rigid insulation with structural facings. When panels are joined correctly they create a stiff, insulated wall system with a predictable geometry that suits modern garden-room construction.
SIPs are not the entire building. The base, floor, roof strategy, membranes, cladding, windows, doors and service details still need to be designed and installed properly.
How Goldridge uses SIPs
Goldridge currently uses SIP construction for the walls and combines that with a traditional timber joist floor approach. That gives an insulated structural wall system while keeping the floor build-up practical and adaptable to the site.
We do not publish invented U-values or pretend that one panel makes every project identical. The actual specification should be explained on the quotation and matched to the room.
Why detailing still matters
Panel joints, openings, membranes and weather protection are where good installation matters. A high-performing material used badly can still produce a poor building. The same applies to cladding and glazing, which have to shed water and work with the structure behind them.
SIPs versus a conventional timber frame
Both systems can produce excellent garden rooms when they are designed and built properly. SIPs offer a quick, precise structural wall approach, while conventional timber framing offers different kinds of flexibility. The choice should support the project rather than being treated as a badge of quality on its own.
