What a SIP panel is
A SIP panel is a structural insulated panel made from two OSB faces bonded to an insulation core. The OSB faces carry racking and fixing loads while the insulation core gives the panel its thermal performance and stiffness.
The panel should be treated as an engineered component. Cutting, notching, fixing, and bearing details should follow the drawings and the panel schedule supplied for the project.
Why the edges matter
Panel edges normally connect with splines, timber, or engineered members. These joints are what turn individual boards into a continuous wall, floor, or roof structure.
Gaps, poor glue lines, missed fixings, or unsupported edges can affect air tightness, strength, and weather protection.
Before you move on
- OKIdentify the panel thickness being used on the project
- OKCheck how splines and edge timbers are shown on the drawings
- OKKeep panels dry and supported before installation
