DESCRIPTIONDESCRIPTIONDESCRIPTION
Dimension stabilityFiber Gypsum is extremely dimension stable and large panels up to 3000x1200mm can be installed with a 0 mm spacing (100% closed joints).

5/5
MDF 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
Plywood 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 impactFiber Gypsum has a good resistance to impact and is suitable for high traffic areas, sports halls, schools, hospitals, restaurants and similar.

5/5
MDF has a good resistance to impact and is suitable for high traffic areas, sports halls, schools, hospitals, restaurants and similar.

5/5
Plywood has a good resistance to impact and is suitable for high traffic areas, sports halls, schools, hospitals, restaurants and similar.

5/5
FlattnessFiber Gypsum is not sensitive to changes in the room’s temperature or humidity and stays flatt over time. Large panel formats can be used.

5/5
MDF is sensitive to changes in the room’s temperature or humidity and large panel formats should be avoided.

3/5
Plywood is sensitive to changes in the room’s temperature or humidity and large panel formats should be avoided.

4/5
Fire Safety of the coreFiber Gypsum contains 83% or more non-combustible minerals and is classified A1-s1,d0 or A2-s1,d0. No impregnating chemicals or fire retardant lacquers need to be used.

5/5
Fire retardant FR-MDF’s with class B-s1,d0 are avaible.

4/5
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
Fiber Gypsum is all the way through non-combustible. Perforations do not effect the fire properties and the whole panel keeps fire class A2-s1,d0, including the veneer and lacquer.

5/5
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
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 15 kg/m², Fiber Gypsum based panels will not vibrate/resonate due to sound waves. Sound will be properly reflected towards to back concert halls or auditoriums.

5/5
With 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
With 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 materialFiber Gypsum contains 94% recycled material and 17% of these are post consumer.

5/5
MDF is made of new raw materials and does not contain any recycled material (and by that no post consumer recycled materials).


Plywood is made of new raw materials and does not contain any recycled material (and by that no post consumer recycled materials).


Thermal massWith a high density of 1150-1250 kg/m³ Fiber Gypsum stores both heath and cold. This property helps to keep rooms at an even temperature which reduces energy consumption.

5/5
MDF 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
Plywood 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
EmissionsFiber Gypsum does not contribute to formaldehyde emissions at all and post treatments like acoustic perforations does not influence the level of emissions.

5/5
MDF 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
Plywood 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 FormaldehydeFibre Gypsum does not contain any glue and will never contain added urea formaldehyde.

5/5
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
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.

3/5
ColorsFiber Gypsums are availabe in Light Grey and Dark Grey. A Dark Grey Core is recommended in combination with dark veneers, dark paints and dark laminates.

3/5
The 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.

5/5
Plywood is not available in pre-colored grades.
