Edge-glued panels are relatively wide and thin non-structural wood products used in the manufacture of other products such as furniture and cutting boards. They are produced from narrow pieces of wood glued along their edges to create products of greater width. Edge-glued components can be thought of as wide boards, except that greater widths are possible than with individual boards, and the edge-glued panels are less likely to warp in service.
The narrow pieces of wood used for edge-glued panels may be waste from other processing operations or are cut from larger pieces of wood to remove visual defects such as knots. The finished panel is more dimensionally stable than a single piece of wood of the same dimensions, resisting warping, cupping and twisting because of the random orientation of the grain in the adjacent pieces.
Edge-glued panels are produced from both hardwoods and softwoods. Individual wood pieces may also be finger-joined along their length to permit the incorporation of smaller lengths of wood into the finished product. The glues commonly used produce light-coloured glue lines—desirable since the products are used in primarily visual applications.
