Lsl o intrallam

Laminated strand lumber is similar to osb but it's composed by poplar wood shavings with particular dimensions (often about 25x300 mm and 0,8 mm thick) bound by waterproof glues in order to form an homogeneous structured panel. Those panels are very resistant to bad weather. Shavings can be lenghtwise or crossed oriented. The first ones are often used for floor beams or roofs, while the second ones are used for pluggings (walls, roofs, floor beams ecc..) because they have more uniform mechanical characteristics towards both directions.
