Thickness guide
Not sure which SIP panel to choose?
122mm
Garden rooms
A practical starting point for non-habitable outbuildings, studios and garden rooms.
172mm
Extensions
Usually the safer default for habitable spaces, annexes and Building Control routes.
222mm
High performance
Used where lower U-values or stronger roof performance are part of the brief.
Need help choosing?
Send drawings or rough sizes before ordering
We can check SIP thickness, openings, U-values, delivery assumptions, and whether a product order or custom kit quote is the better route.
