Glued laminated timber, also called Glulam, is a type of structural timber product comprising a number of layers of dimensioned timber bonded together with durable, moisture-resistant structural adhesives. In North America the material providing the laminations is termed 'laminating stock' or lamstock for short.
By laminating a number of smaller pieces of timber, a single large, strong, structural member is manufactured from smaller pieces. These structural members are used as vertical columns or horizontal beams, as well as curved, arched shapes. Glulam is readily produced in curved shapes and it is available in a range of species and appearance characteristics to meet varied end-use requirements. Connections are usually made with bolts or plain steel dowels and steel plates.
Glulam optimizes the structural values of a renewable resource - wood. Because of their composition, large glulam members can be manufactured from a variety of smaller trees harvested from second- and third-growth forests and plantations. Glulam provides the strength and versatility of large wood members without relying on the old growth-dependent solid-sawn timbers. [2] It reduces the overall amount of wood used when compared to solid sawn timbers by diminishing the negative impact of knots and other small defects in each component board.

Βρίσκω στον ιστότοπο της ΕΕ διάφορες αποδόσεις και μάλιστα ο συγκεκριμένος όρος έχει απασχολήσει και το Δικαστήριο της ΕΕ, σε απόφαση του οποίου γίνεται λόγος για «επικολλητή ξυλεία».
Μήπως ξέρει κανείς κάτι περισσότερο;
Ευχαριστώ!
