MDF is a wood based material, very well suited for furniture and other more complex carpentry solutions. Strict building regulations for public rooms will at the same time mean restrictions for the use of MDF.

DESIGN

MDF is sensitive to indoor climate changes so large formatted panels and zero spaced joints should be avoided. MDF is a very suitable material to create curved panels and integrated furniture solutions, like kitchen cabinets, etc.

FIRE

MDF cannot be vacuum impregnated with chemical fire retardants. To produce a fire retardant MDF, the fire retardants must be pre-mixed into the substrate when producing the FR-MDF board. The MDF core of the Panel or Linear Rib can be classified B-s1,d0, but not the Panel or Rib product as a whole, including the surface veneer, surface finish and installation system. To solve this problem some suppliers add a fire retardant lacquer to the surface, but these must be applied very thick, eliminating the option to create designs with a wood grain structure. Fire retardant lacquers contain salts, are not truly transparent and do not allow post treatments like acoustic perforations or cutting on site.

EMISSIONS

MDF cores are produced with a lot of glue, but versions using correct glues and 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 PropertyMDFScore
Dimension StabilityMDF is sensitive to changes in the room’s
temperature or humidity and should be
installed with a 4 mm spacing per 1000
mm of length and width.
2/5
Resistance to impactMDF has a good resistance to impact and
is suitable for high traffic areas, sports
halls, schools, hospitals, restaurants and
similar.
5/5
FlattnessMDF is sensitive to changes in the room’s
temperature or humidity and large panel
formats should be avoided.

Fire Safety of
the core
Fire retardant FR-MDF’s with class
B-s1,d0 are avaible
4/5
Fire Safety of the whole panel, including
the veneer, lacquer and perforations
With veneer FR-MDF drops to fire class C
or lower. FR-Lacquers can be used, but
the salts and thickness requirements
make them non-clear. Perforated holes
can not be lacquered.
2/5
AcousticsWith 9,5 kg/m², MDF 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 materialMDF is made of new raw materials and
does not contain any recycled material
(and by that no post consumer recycled
materials).
0/5
Thermal massMDF 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
EmissionsMDF 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
MDF is available in non added
ureaformaldehyde versions. MDF
contains a lot of glue, so when incorrect
glues are used, a lot of urea
formaldehyde will be added.
3/5
ColorsThe natural color of MDF is brown, but is
available in many pre-colored grades.
Please note that pre-colored MDF will
have minimum MOQ’s and longer lead
times
