CORE MATERIAL ACADEMY

We at Gustafs are experts in using High Density Fiber Gypsum materials for the cores of our Panel and Linear solutions. In this Academy section we will learn you more about why! Fiber Gypsum really has outstanding properties compared to other common core materials when it comes to Fire Safety, Form Stability, the Final Aesthetic Result, Acoustics, Recycled Content and Emissions. Read more in our “Core Material Guide”.

GUSTAFS CORE MATERIAL GUIDE

FIBER GYPSUM

Fiber gypsum is a core material that gives both interior Panels and Ribs many outstanding qualities, leaving no restrictions to use them everywhere for walls and ceilings, also in the most demanding types of rooms. Fiber Gypsum solutions are extremely well suited for use in escape routes, sky-scrapers, schools, meeting rooms, concert halls, hotels, airport terminals, restaurants and all other types of public meeting places.

DESIGN

Fiber Gypsum is non-sensitive to indoor climate changes and allow you as a designer to work with the combination of large formatted panels and zero spaced joints in between the panels. This combination gives an exclusive and beautiful end-result, lasting over its full life time, without bulging or warping. Fiber Gypsum Ribs will be 100% straight and stay 100% straight.

FIRE

The fire retardant properties of Panel and Rib systems based on a non-combustible Fiber Gypsum are not reliant on chemical treat­ments. Instead it is the mechanical composition of the components which create the end result. Compared to other solutions using impregnated core materials or thick protecting top-coatings, Fiber Gypsum solutions are protected truly homogeneously and will always remain 100% fire safe even when perforated with thousands of acoustic holes per square meter or when cut on site. The result is undoubted fire classifications up to A2-s1,d0 class, including the surface material, surface finish and installation system.

EMISSIONS

Fiber Gypsum cores are extremely low-emitting. One of the reasons is that they are produced without glues and due to that also automatically without added urea-formaldehyde. Interior Panels and Ribs, containing 97% Fiber Gypsum, will per definition have very low TVOC and formaldehyde emissions. The total surface area of a product will have impact on the level of emissions. Because Fiber Gypsum is almost non-emitting, surface area increasing post treatments, like acoustic perforations or slicing the material into Linear Ribs, will not affect the emission classification.

MDF

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.

PLYWOOD

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.
