Can LVL beam be used outside?
Also question is, can LVL beam be used outdoors? Microllam® LVL should only be used in dry (interior use) applications and should not be pressure treated. Also some wood species used in Microllam® LVL production may not be appropriate to absorb the chemicals used in treatment. The best choice for exterior use is our treated Parallam® Plus PSL.
What happens if LVL beam gets wet?
LVL beams are GLUED together, if enough moisture gets in there the glue could start peeling apart making the beam considerably weaker. “If the LVL got wet enough to swell up and then they dried out and show any sign of delamination, they lose a lot of strength. Also to know is, can LVL beam be used outdoors?
Can LVL be exposed to the weather?
NelsonPine LVL should not be used in external applications where it is not protected from the weather and moisture. The life expectancy of untreated and unprotected NelsonPine LVL fully exposed to the weather and/or in contact with the ground is less than 5 years. Secondly, can LVL get wet? LVL is intended for use in covered, dry conditions only.
Are LVL beams only for moisture content <16%?
I recently saw a laminated veneer lumber beam being used in an outdoor application (header on a deck). This made my engineer sense tingle, because I'm pretty sure that ALL LVL's are only for moisture content <16% applications. (Literature on LP's web site has a note to this effect.) Can anyone confirm or refute my assertion?

Can LVL get wet during construction?
Wetting during construction may lead to temporary elevated moisture content and dimensional changes. Once covered, the I-joists or LVL will ultimately dry and re-equilibrate to the ambient humidity conditions, but some expansion or swelling may remain after redrying.
Can you use LVL timber outside?
H3 Exposure (Outside, above ground, intermittently exposed to weather) Wesbeam LVL is also available as H3 Light Organic Solvent Preservative (LOSP) treated products enabling them to be used in outside, above ground environments where periodical wetting may occur.

DO levels rot?
Paul Fisette, director of building materials and wood technology at the University of Massachusetts Amherst and a JLC contributing editor, responds: Like any wood that is neither treated nor naturally decay-resistant, an LVL — which is typically made of southern pine or Douglas fir — will rot when exposed to excessive ...
Can framing be done in the rain?
Your framing lumber and the oriented strand board (OSB) are going to be fine. The glues used to make OSB are water-resistant because the manufacturers know that virtually no one can build a home that won't get wet before the roof and siding is applied.Sep 8, 2015
What is LVL lumber?
Laminated veneer lumber (LVL) Are you aware of the product and it's characteristics? The veneers are then bonded together under pressure and heat with waterproof adhesives. LVL beams are exceptionally strong, solid and straight making them exceptional for most primary load-carrying beam applications.
Can LVL be stored on the ground?
On site, LVL members should be stored flat, off the ground and kept dry prior to installation. While short-term weather exposure will not unduly affect its performance, long-term exposure will require preservative treatment and finishing with a protective coating.
What is H3 treated LVL?
H3 treated LVL's are for outdoor and /or weather exposed applications and provide the same termite resistance as T2 timber and the same anti rot as any other H3 treated timber.
Is LVL a good product?
I would follow manufacturer's guideline to the letter. LVL is an excellent product for correct application. The jury is still out on whether external application even when following guidelines is correct application.
