Independent tests on Sips Industries panels have shown that they can be up to 7 times stronger than conventional timber frame.



Fire Safety

The standard finish for interior walls and ceilings is dry lining using one layer of 12.5mm plasterboard with fire-tape on the joints. This achieves a Class 1 fire rating.

The optimum Class 0 (zero) fire rating is achieved if two layers of plasterboard are attached.

Panels have passed the rigorous fire endurance tests. The solid-core panel construction eliminates the chimney effect that causes fires to spread rapidly through hollow conventional-built walls. The super-bonding, insulating foam we use is non-toxic and chemically inert.

Life Expectancy

The Sips Industries panel is deemed fit to last the life expectancy of the building.

Roof design

Recommended roof design is carried out by a structural engineer where necessary. Panel fixings supplied with the panels are deemed to satisfy this. In areas of high winds or loads or where light weight roof systems are incorporated, it is advisable to add fixing straps at recommended intervals, connecting the underside of the roof panel to the vertical wall members.

Foundation to wall detail

Sole plates are attached to the slab by means of mechanical fixing at specified centers. The sole plate is made of treated soft wood, width dependent on the thickness of the panel core.


It is recommended that all enquires be directed through our offices for jointing details as these change from application to application. All drawings are processed through a structural engineer and are fully certified.
