Engineered timber is created by joining three sheets of timber together, where the middle sheet sits against the grain of the one above and below it. This is known as laminated timber. Alternating the grain of the wood like this prevents the timber from moving, swelling, shrinking and warping, creating a very strong and stable piece of timber.
The timber is cut to remove any knots or imperfections in the wood. Typically, this is done by a machine. The pieces are then joined back together in an interlinked fashion called finger jointing. Again, this gives the timber added strength.
Solid timber is simply timber cut directly from the tree in length form. Due to its natural state, it still contains the knots and imperfections that you would expect.
Engineered timber is the most environmentally friendly, greenest material to build with. Any waste that is generated is recycled and growing trees take carbon out of the atmosphere, meaning that timber is carbon negative.
