Mineral Ceiling Tiles enjoys great preference in most of the commercial and residential buildings due to their great ability of sound absorption, resistance to fire and their beautiful appearance. The quality of these tiles could be arbitrary, and it is crucial to know how to identify quality tiles to ensure maximum performance and durability of your ceiling installation. Important determinants include the quality of mineral wool plate, surface of mineral wool board, shape of mineral wool board and performance of mineral wool board.

The Mineral Wool Plate Quality

The production of mineral wool board is from the raw materials and so, a good mineral wool board will have to utilize mineral fiber cotton of the good quality. The main material making mineral ceiling tiles call mineral wool and so it follows that the quality of this raw material is key in determining the performance and lifespan of the tiles. Good quality mineral wool plates are produced generally by combining basalt with other mineral ores and slag. These materials are then melted into a liquid form and fibers are made from their spinning process and afterward, they are bonded by adhesive materials.

The following aspects should be evaluated when looking at the quality of the mineral wool plates:

• Densité: The thicker the mineral wool, the better the protection it affords since it controls heating injury and sound absorption. Such mineral wool tiles should have a minimum density of 150kg/m3.

• Composition: It is important to confirm that the material does not include any hazardous ingredients, especially in the case of mineral wool.

• Fabrication Normes: It is important the product conformed with the applicable standards or certification for the industry which includes, ISO and which includes ASTM.

The Surface of the Mineral Wool Board

At the stage of the composition of the mineral wool board there is an attempt to do some surface treatment. Common manufacturers will carry out polishing of the surface of the mineral wool board and device surface spraying this is where mineral board is meant to be displayed at its qualities value. The main reason for finishing the surfaces and edges of mineral wool boards is not only for aesthetics but is essential in areas such as defining the sound level or controlling moisture retention. The surface must be flat, clean, and defect free.

Following are the points to consider while performing this activity:

• Douceur: A good smooth surface suggests a good skill in manufacturing and paints can stick very well when you need to customize the tiles.

• Coating and Texture: Protective layer is present in many quality tiles increasing their life span. Modified surfaces can improve sound absorption but must be homogenous and no chipped or scratches are found.

• Cohérence des couleurs : Since ceiling tiles are fitted close to each other with little or no space in between, color consistency across the tiles looks pleasing. Color inconsistencies might indicate poorly controlled storage of the tiles, prior to installation.

The Shape of the Mineral Wool Board

Our mineral wool board of 600*600 specification is white and is conventionally used as a ceiling board with reasonably simple ceiling modeling. Also, a high quality mineral wool board ceiling can do a great deal of modeling. The shape and the sizes of the mineral wool boards are extremely important so as to facilitate a perfect installation and the appearance of the ceiling. The quality tiles need to have precise uniform dimensions with good sharp edges.

Some of the shape factors are:

• Précision dimensionnelle: The diameter should conform to the specifications ordinarily standard sizes like 600mm by 600mm or 1200mm by 600mm. Variations may create installation problems and ugly gaps.

• Edgiing Style: Select tiles with sharp clean edges that are appropriate for the grid type of ceiling system to be used. Edges commonly include square edge, tegular edge and concealed edge. The edges should be intact and clean.

• Épaisseur: All boards should be of standard thickness in order to have uniform sound properties and structural integrity.

The Performance of the Mineral Wool Board

When considering ceiling tiles made of the mineral ceiling tiles, one needs to look into factors such as acoustics, fire resistance, ease of mounting, and longevity. The effectiveness of the mineral wool board is the most straightforward criterion by which the quality of the board can be depicted. Most manufacturer will at least provide some additional gasket of the relevant mineral wool board, which will include such information as its sound absorption characteristic index, sound separation index, fire reactive index, moisture barrier index, and performance index.

Indicators to be assessed are:

• Isolation acoustique: Quality mineral wool boards ought to exhibit high sound absorbing efficiency or high sound absorption coefficients. Typical noise reduction coefficients range generally from 0.55 to 0.75.

• Résistance au feu: Check the fire rating of the tiles, this is crucial as it indicates the extent to which the tiles will contain the fire spread. One should seek no less than Class A.

• Isolation thermique: Good thermal insulation can also help improve energy efficiency in buildings because it reduces heat flow through walls.

• Moisture and Sag Resistance: Performance under moisture, and humidity and sagging are very important mostly in humid regions. Good quality mineral ceiling tiles should not sag and warp after some years of usage.

• Facilité d'entretien: It is always preferable that any tiles should be of a material that would be easy to clean. Ceiling tiles can be enhanced with stain resistant and scratch resistant surface finishes.

These factors allow you to choose really good mineral ceiling tiles of high quality which will perform, look, and last well in your projects. Time invested in evaluating these factors for a given ceiling design, would assist in having a holistic ceiling that meets the acoustic, fire resistance and design requirements.
