Plywood

is a wood based material, normally used in constructions and not as a surface material. But the rough look of Plywood has increased its popularity. Building regulations for public rooms mean restrictions for the use of Plywood as an indoor surface material.

DESIGN

Plywood is sensitive to indoor climate changes so large formatted panels and zero spaced joints should be used with care. Plywood can be used as it is, just sanding and lacquering its rotation cut top veneer in birch or pine, or a veneer in another wood specie can be glued to the board surface.

FIRE

Plywood can be vacuum impregnated with chemical fire retardants, but the non-transferring glue in between the multiple veneer layers makes it hard for the impregnation fluid to reach the whole core of the plywood board. Its only a limited number of producers who master this tricky process.

EMISSIONS

Plywood cores are produced with a lot of glue, but versions with approved emissions are available. Surface area increasing post treatments, like acoustic perforations or slicing the material into Linear Ribs, may affect the emission classification.

Material PropertyPlywoodScore
Dimension StabilityPlywood is sensitive to changes in the
room’s temperature or humidity and
should be installed with a 2 mm spacing
per 1000 mm of length and width
3/5
Resistance to impactPlywood has a good resistance to impact
and is suitable for high traffic areas,
sports halls, schools, hospitals,
restaurants and similar.
5/5
FlattnessPlywood is sensitive to changes in the
room’s temperature or humidity and
large panel formats should be avoided.
4/5
Fire Safety of
the core
Plywood can be impregnated to class
B-s1,d0. The impregnation and drying
process can lead to warping panels.
4/5
Fire Safety of the whole panel, including
the veneer, lacquer and perforations
Plywood including the top veneer can be
impregnated to B-s1,d0. Impregnation
cannot pass the glue layers in plywood,
perforations might expose nonimpregnated material.
2/5
AcousticsWith 9,5 kg/m², Plywood based panels
will more easily start to vibrate/ resonate
due to sound waves. Sound will not be
properly reflected towards to back
concert halls or auditoriums.
3/5
Recycled materialPlywood is made of new raw materials
and does not contain any recycled
material (and by that no post consumer
recycled materials).
0/5
Thermal massPlywood is not very good at storing
heath and cold and rather works the
opposite way by isolating the concreate
structure of a building which ortherwise
can store heat and cold.
2/5
EmissionsPlywood is available in formaldehyde
class E1. After adding an acoustic
perforation, the E1 classification is
normally not valid anymore as the total
emitting surface increases.
2/5
No added Urea
Formaldehyde
Plywood is available in non added
ureaformaldehyde versions. Plywood
contains a lot of glue, so when incorrect
glues are used, a lot of urea
formaldehyde will be added.
2/5
ColorsPlywood is not available in
pre-colored grades.
