Mineral fiber ceiling panels consist of: mineral fiber, perlite, clay, binders – starch, latex, waste paper and gypsum.
Suspended ceilings made of mineral fiber panels can be not only flat (A, B), but also, for example, cellular (C)
It should be noted that the mineral fiber used for the manufacture of this group of ceilings is stone wool. And although fiberglass also belongs to the group of mineral fiber materials, it is generally accepted to call ceilings made of stone wool mineral fiber, and from fiberglass to take it into a separate group. We will adhere to this established classification..
In the production of mineral fiber ceilings, a lot of attention is paid to the binder. Depending on what is more starch or latex, the technical characteristics of the products depend, i.e. their moisture resistance. If there is more latex, then it is a moisture-resistant panel that can be used in rooms with humidity up to 95-99%. And if starch predominates, then at high humidity the panel sags. Latex is more expensive than starch, therefore moisture-resistant panels are more expensive than products with low moisture resistance.
Mineral fiber panels are distinguished by high fire safety and acoustic characteristics (high sound absorption).
The color scheme of the panels can be different, up to black (for movie theaters, for example). The range of surface textures offers the widest choice for designers and architects – smooth, micro-perforated or embossed surfaces, crisp printed geometries, graphic designs, designer edge designs and open mesh panels. All this makes it possible to create individual compositions from ceiling tiles..
Designer ceilings allow for any exclusive interiors, both residential and public, and industrial interiors. A designer in collaboration with a manufacturer can create three-dimensional ceilings of almost any complexity, with built-in lighting, with offset levels, etc..
The layout of the panels can be with a visible or hidden suspension system, freely fixed (corridor), cellular or plate. In fig. the interiors made of mineral fiber panels are presented, illustrations speak better than words about the modern capabilities of this material.
Several types of panels are produced from mineral fiber: in addition to traditional, laminated, from ceramic-like mineral fibers, combined, as well as from soft fibers.
Traditional panels, acting as acoustic ones, have a rough surface with depressions of various shapes. To give the surface color, the panels are primed and painted. Note that painting the panels on their own can lead to the loss of their acoustic properties..
Hygienic boards are painted with bactericidal paint, which limits the growth of bacteria on the surface of the ceiling.
Have laminated panels the surface can be faced with various materials: textured fabric; special fiberglass (including painted); aluminum foil (which can be covered with vinyl film treated with a bactericidal or fungicidal agent); smooth polyester film (repels dust) and other coatings.
Ceramic mineral fiber panels characterized by maximum resistance to high temperatures, they have passed the steam test with temperatures up to 135oC. The panels are resistant to chemically active vapors, corrosion and humidity, and are designed for installation in harsh industrial and marine conditions, swimming pools. Can be installed in unheated rooms.
They consist of cellulosic and mineral fibers, special organic binders and inorganic fillers. The surface of the panels is primed and painted. Panels withstand 100% relative humidity at 40oC.
Combined panels are a sandwich with a mineral fiber core covered with smooth or perforated metal. These products provide a successful combination of the positive properties of mineral fiber with the optical attractiveness of metal..
Soft fiber ceilings have the highest sound absorption and are a good solution for schools or hospitals. Additional advantages of soft fiber boards are increased moisture resistance and the ability to create curved surfaces. The front surface of the slabs is painted for a decorative effect.
Mineral fiber panels are installed on the grid. Their dimensions are 600×600 mm, 1200×600 mm, etc., their weight is: from 3 to 8 kg / m2, thickness is 12-25 mm.
Plates can be installed indoors when it is dry, plastering and painting work is complete, windows and doors are built in and glazed. The heating system must be operated to provide a standard operating temperature of 15-30oC. The relative humidity should not exceed 90%. In rooms with temporarily or permanently high humidity, special measures must be taken. It should be remembered that cookers designed for a specific relative humidity have guaranteed performance under the conditions of a given relative humidity.
