Given its versatility, glued laminated timber is the ideal material for building large structures, allowing for a wide variety of shapes, as well as structures with large spans. There are 3 types of glued laminated timber: spruce wood, commonly known as white bark, Scots pine wood, commonly known as red bark, or radiata pine wood, also known as insignis pine, which are used in different situations. With different strength classes for each use and with the right treatment, it is possible to build large structures and bold shapes, without ever compromising durability and architecture.
