Lagging

 

a lumber product cut to size; produced from the side of a log by sawing. If the convex side of the lagging is not sawed through or is sawed through for less than half of its total length, the product is called side lagging; if the convex side is sawed through for more than half of its length, the product is called board lagging. Lagging is used to make scaffolding, centering, and support material.
