scope:

This International Standard specifies test methods for determining, for use in roofs, the structural properties of double-sided load bearing structural insulated panels having

- two face layers, at least one of which is a wood-based structural panel, and

- a core made of a thermally insulating material having sufficient shear strength to cause the face layers to act together structurally.

NOTE 1 Gypsum-based structural boards can be used as one face layer.

NOTE 2 Panels can contain internal framing or bracing.

NOTE 3 The performance of panels with non-structural insulation is generally calculable according to design codes such as EN 1995-1-1, or tested according to appropriate standards.
