A BUILDING MEMBER

A building member is formed from a pair of spaced apart boards connected between the opposed faces by narrow connecting members which extend the leng th thereof. The edges of the connecting members are preferably retained within channels in the opposed faces of the wooden boards. The boards and the connecting members enclose an insulation space which may be filled with an insulation material. A selection of advantageous connection profiles is disclosed for the connectio n between the edge of the connecting member and the channel of a board. One of the boards may instead comprise an extruded siding, for example of aluminium or plastic , with a leg extending perpendicularly from the siding forming the connecting member. The building member may be constructed in a simple process and reduces wastage o f material which often occurs in forming laminated solid timber building products while offering enhanced insulative properties.
