Glued laminated timber can be used for the construction of large span beams taking up a heavy load but also to limit dimensional variations.
The products are manufactured with at least two butted strips of thickness less than or equal to 45mm. Glued laminated timber is made up of solid wood slats of identical mechanical class. The products can be of visible and non-visible quality, and the moisture content is between 11 and 15%.
BLC products are planed on 4 sides and chamfered.
• Spruce • Larch • Douglas fir • Autoclaved pine
Visible quality: AP.
Industrial grade: NA.
Width: from 80 to 240 mm. Height: from 120 to 1360 mm. Standard length: 13,5m.
Other lengths possible on minimum production from 4m to 16m.
Classes of mechanical resistance:
The strength classes of glued laminated timber elements are:
GL24H for Spruce and Douglas, GL28 on request.
The bonding is carried out with a type I adhesive (MUF glue) according to EN 301.
Mechanical characteristics for the calculation:
Dimensioning of glued laminated timber beams is done in accordance with EUROCODES 5 (EC5) rules. The characteristic stresses to be used are those defined by standard EN 14080
