Large dimensions of wood can support heavy loads and facilitate long spans, in addition to being surprisingly fire resistant. 3 Finger-jointed lumber (also known as end-jointed and end-glued) is manufactured using short, dry pieces of wood that have been machined on each end and joined using a water repellent structural adhesive. This technique is ecologically beneficial, as it makes use of short pieces of wood to create a finished product that is larger, more stable and easier to align, and is often combined with Glulam and CLT type products to make substantial timber structural elements for "Plyscrapers" etc - (see below).
