Who is the LVL handbook targeted for?
The first three chapters are suitable reading for anyone interested in wood construction and use of LVL. Chapters 4–9 are technical details mainly targeted for engineers.
What do ‘P’ and ‘C’ used in the strength classes stand for?
P = all veneers are parallel, C = at least two veneers crossbond
Does the handbook provide all the necessary information for a local engineer in any European country to design with LVL?
No. It will offer enough info on LVL for most of the cases though.
LVL handbook shows general information on LVL, can I find somewhere more information on Kerto LVL?
More information related to Kerto LVL i available at Kerto LVL prodcut page and Kerto LVL Manual.
Which producers back-up European LVL handbook?
Metsä Wood and Stora Enso.
Different manufacturers use different species but how do the strengths differ?
Density is generally the main driver for strength and stiffness values of LVL. Producers can produce from what spices they want to obtain the standard class values.
How does veneer thickness affect LVL properties?
Generally thinner veneers offer better strength, the per producer thickness is related to properties and production speed.
Why are given strenght class properties different from Kerto LVL properties?
Strength and stiffness properties are aligned with all producers and do not only reflect just Kerto LVL.
For Kerto LVL we use our own material values stated in Declaration of Performance documents.
How is LVL present in design tools?
The list of tools is available in Handbook’s section 1.11. See also the list of applications including Kerto LVL . Generally there is either cross-section library or material properties.
