The element manufacturers benefit from the project-specific dimensions of the boards - lengths of two to a maximum of 25 metres are available. The usual width is 0.9 to 2.5 metres. In addition, thicknesses of 21 to 75 millimetres are possible, with Kerto Kate also thicknesses of 15 and 18 millimetres.
Kerto LVL has transverse layers, and cantilevers over the corner area - i.e. on the eaves and gable side - are also possible. In addition, the boards can be laid parallel and transverse to the rafter and beam position. The panels are also available with half-laps, which enables them to create bracing roof diaphragms.
The Kerto LVL panels can also be connected using coupling boards. The roof diaphragm is usually produced with offset joints on rafters or trusses. Spans of 0.5 to 2.5 metres are the rule. It is fastened with staples, nails or screws.
Kerto LVL can also act as a vapour barrier in the roof area. Without further measures, the natural wood-based material can achieve fire resistance class F30 with the appropriate thickness.
The Finnwood software is ideal for structural calculations, offering the flexibility to select various aspects of the supporting structure, such as spans, support widths, inclinations, loads, and more. Additionally, Kerto Q-panels are included in most design software. Metsä Support guides proven design principles and detailed execution information
