Structural Insulated Panels (SIPs) Explained

Building systems

SIP homes explained

HebHomes SIP kit homes use structural insulated panels to form the building envelope. This lightweight panel approach combines structure and insulation, with additional wall layers completed on site to your agreed specification.

Structure and insulation,
combined in a panel.

Our SIP panels have a rigid polyurethane (PUR) insulation core bonded between OSB boards. They offer a lighter panel option, with additional insulated lining and other specified layers completed on site.

When to consider SIP

Your plot and access

The lighter panels can make SIP practical where access is restricted or CPS crane requirements would be difficult or costly. The lifting method is assessed for each site.

Your wall specification

Our SIP wall uses a thinner panel with additional insulated lining to achieve the specified wall performance. This keeps panel weight and cost central to the choice.

Your site programme

Plan the panel installation and follow-on work together, including weather protection and building services.

Why does our SIP wall include additional insulation?

Our thinner SIP panel and insulated lining work together to achieve the specified wall performance. This balances thermal performance with panel weight and cost. Your agreed wall specification sets out the panel and lining provided.

Can services be cut into a panel?

Service routes and penetrations must follow the approved design. Discuss changes with the project team before altering structural panels.

Is SIP a complete finished home?

The panel system is part of the building. HebHomes’ core service is Supply + Erect; the remaining works follow your chosen build arrangements.

Certification and your home warranty

System certification provides evidence about a specified construction system. The structural warranty for your individual home is arranged separately, and your lender confirms whether the proposed construction and warranty meet its requirements.
