Glulam

Glued laminated timber (GLT) is a type of structural engineered wood used in construction, interiors, furniture and products. Parallel lengths of kiln-dried timber are laminated together to form predictable structural ceiling beams, support posts, lintels, girders and main weight-bearing structures in roofs, rafters, overhanging roof structural elements, and terrace and balcony structures.
