"Laminated" or "engineered" logs are a quite different approach to log home building. Full trees or, alternatively, sawn cants, are brought to a mill equipped with a dry kiln, the bark is removed and the trees are sawn into boards usually no thicker than two inches thick. These boards are then taken to the dry kiln where because of their size they can be dried without causing severe damage to the wood. Timber destined for glue lamination must be brought down below 15% moisture before the lamination process will even work so typically these timbers are dried to around 8-10% moisture. The drying process varies on the species of lumber but can be done in as little as a week. Once the drying process is complete the planks are sent through a surfacer or planer which makes the face of the lumber perfectly smooth. These planks travel to a machine which then spreads a special glue on the interior boards.

Depending on the type of glue and type of mill there are two ways to finish the lamination process, one type of glue reacts with radio frequency to cure the glue in a matter of minutes and the other uses a high pressure clamp which holds the newly reassembled timbers under pressure for 24 hours. Once the glue has dried the end result is what is called a "log cant" that is slightly larger than the buyers desired profile. These log cants are run through a profiler and the end result is a log that is perfectly straight and uniform.

Some mills are capable of joining together quite small timbers by using a combination of face and edge gluing as well as a process known as finger jointing. These boards which would be scrap to any other mill could be used in the center of a laminated log or beam to bring waste to a minimum.
