<\/td>DESCRIPTION<\/td>DESCRIPTION<\/td>DESCRIPTION<\/td><\/tr>
Dimension stability<\/td>Fiber Gypsum is extremely dimension stable and large panels up to 3000x1200mm can be installed with a 0 mm spacing (100% closed joints).

5\/5<\/strong>
<\/td>		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<\/strong><\/td>		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<\/strong><\/td><\/tr>
Resistance to impact<\/td>Fiber Gypsum has a good resistance to impact and is suitable for high traffic areas, sports halls, schools, hospitals, restaurants and similar.

<\/td><\/tr>
Flattness<\/td>Fiber 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<\/strong>
<\/td>		MDF is sensitive to changes in the room’s temperature or humidity and large panel formats should be avoided.

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

4\/5<\/strong>
<\/td><\/tr>
Fire Safety of the core<\/td>Fiber 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<\/strong>
<\/td>		Fire retardant FR-MDF’s with class B-s1,d0 are avaible.

4\/5<\/strong>
<\/td>		Plywood can be impregnated to class B-s1,d0. The impregnation and drying process can lead to warping panels.

4\/5<\/strong>
<\/td><\/tr>
Fire Safety of the whole panel, including
the veneer, lacquer and perforations<\/td>		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<\/strong>
<\/td>		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<\/strong>
<\/td>		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<\/strong>
<\/td><\/tr>
Acoustics<\/td>With 15 kg\/m\u00b2, 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<\/strong>
<\/td>		With 9,5 kg\/m\u00b2, 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<\/strong>
<\/td><\/tr>
Recycled material<\/td>Fiber Gypsum contains 94% recycled material and 17% of these are post consumer.

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

<\/td><\/tr>
Thermal mass<\/td>With a high density of 1150-1250 kg\/m\u00b3 Fiber Gypsum stores both heath and cold. This property helps to keep rooms at an even temperature which reduces energy consumption.

5\/5<\/strong>
<\/td>		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<\/strong>
<\/td><\/tr>
Emissions<\/td>Fiber Gypsum does not contribute to formaldehyde emissions at all and post treatments like acoustic perforations does not influence the level of emissions.

5\/5<\/strong>
<\/td>		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<\/strong>
<\/td>		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<\/strong>
<\/td><\/tr>
No added Urea Formaldehyde<\/td>Fibre Gypsum does not contain any glue and will never contain added urea formaldehyde.

5\/5<\/strong>
<\/td>		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<\/strong>
<\/td>		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<\/strong>
<\/td><\/tr>
Colors<\/td>Fiber 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<\/strong>
<\/td>		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<\/strong>
<\/td>		Plywood is not available in pre-colored grades.
