1.7.4 Edge profiling
Edges of LVL panels can be profiled with easing, half lap,
tongue & groove (T&G) or groove & groove (G&G) profiles.
Long edges can be profiled on a milling cutter line, and profil-
ing of all edges can be done on a 5-axis CNC machine.
1.7.5 Surface treatments
LVL manufacturers provide different kind of surface treat-
ments for their products:
• Moisture protection provides improved resistance against
temporary weather exposure during storage, transport and
on the building site.
• Treatment against mould reduces the risk of mould growth
and blue stain and is recommended for use in service class 2
conditions, e.g. in roof structures of attics and shelters.
• Fire retardant treatments improve the reaction to fire clas-
sification of LVL members from D to C or B class, enabling
a wider range of applications. Except for certain paints, fire
retardant treatments can be used only in service class 1 con-
ditions.
• LVL surface can be painted with fully pigmented non-trans-
parent paints or stained with translucent stain or varnish.
