CLT (cross laminated timber)
CLT is a wood panel product made from gluing layers of solid timber together. Each layer is perpendicular to adjacent layers. Usually the outer layers have the same orientation (the glue lines are the same way), hence the odd number of layers of wood like 3, 5 or 7.
CLT must fulfil the standard EN 338’s C24 strength class requirements.
CLT can be used as a structural element in buildings and structures (wall, floor and roof elements) according to Eurocode 5 end-use classes 1 and 2. Usually CLT is supplied with factory made openings for doors and windows. CLT can also be used for facades and interiors.
CLT is manufactured in thicknesses 60- 400mm, with a width up to 3,200mm and length up to 16,000mm, depending on the manufacturer.
Glulam board
Glulam boards are made of solid timber, usually used for the manufacture of furniture, shelvings and staircases. Glulam boards are manufactured for solid timber either by gluing together planed strips, or by gluing pieces of timber and then splitting it to sheets of desired thickness.
Most common species for glulam boards are Redwood (Pine) and Whitewood (Spruce). Glulam sheets can be delivered also with various machinings and even surface treatments.
Commonly the glulam is delivered in thicknesses of 6-70mm, widths of 170-1,250mm and lengths of 300-5,000mm.
