Magnesite glass sheet, the application, the disadvantages of which will be presented in the article, is a modern building material with excellent quality characteristics. It has the widest scope in the implementation of interior and exterior finishing work. A number of builders believe that these canvases, which are also called magnelite, represent a worthy alternative to drywall. That is why you may wonder what to choose - a glass-magnesite sheet (SML) or drywall (GKL).
The first material outperforms the second in a number of ways. Home craftsmen and representatives of professional companies most often use standard materials, due to the lack of information about new solutions. However, magnelite saves money and time during work.
General Description
Magnesite glass sheet, the application, the disadvantages of which will be described below, has an interesting structure. It contains magnesium oxide, perlite, magnesium chloride, as well as finely dispersed woodshavings. In the production process, fiberglass mesh is also used. Different manufacturers have different percentages of ingredients, this is due to different classes of material. Among them are "Premium", "Standard", "Economy class". If you want to use stronger sheets, then you should prefer those with a high content of magnesium oxide. As a rule, glass-magnesite sheet, the application, the disadvantages of which are described in the article, contains MgO in the amount of 40%, this is a premium product, while MgCl2 is added in the amount of 35%.
Structure features
The material is made in the form of sheets, the thickness of which can vary from 4 to 12 millimeters. The most common dimensions of the canvas are 2440x1220 millimeters. The outer side of the canvas has a smooth surface, it does not require additional processing, you can immediately stick wallpaper on such a base, and then apply paint. As for the side, it is more rough, as it is not polished. Sheets can be installed by either party. Most often, LSU is installed outside with the back side for plastering, due to more impressive adhesion qualities.
Use area
If you are interested in LSU (glass-magnesium sheets), what it is, where and how to apply, you definitely need to find out even before purchasing the product. The described material has a wide range of applications,it is used for decoration of residential, industrial and public buildings. In private construction, LSUs are used when it is necessary to install arches, walls, partitions, suspended ceilings. This material can be used when finishing slopes, communication shafts, and ceilings. It is convenient to use sheets as fixed formwork for pouring lightweight concrete. With the help of glass-magnesite, the external walls of houses are finished, followed by the application of finishing materials.
Key features
If you are interested in LSU (magnesite slab), you should know its composition, advantages and disadvantages even before starting work. Among the advantages are moisture resistance, low weight, flexibility, resistance to biological effects, as well as a wide range of applications. Sheets do an excellent job with the effects of chemicals on their surface. Consumers choose this material also for the reason that it is environmentally friendly, resistant to frost, long service life, strength and fire safety. In the latter case, glass-magnesite sheets are superior to similar materials. The canvas does not burn even at a temperature of 1200 degrees. According to the degree of combustibility, it can be attributed to the highest class A. It includes materials such as metal, stone and concrete.
What other positive features are worth paying attention to
Magnesium glass sheet (GML), the application, the characteristics of which are mentioned in the article, does not delaminate, does notswells and does not deform, which is true with a sufficiently long exposure to moisture. The material perfectly resists conditions with high humidity, which indicates the possibility of using sheets in baths, saunas, swimming pools, as well as in basements.
For use in conditions with a high level of humidity, another important factor is biostability. The surface of the canvases is resistant to fungi, mold, insects and bacteria. Do not harm LSU acids and caustic alkalis. You can count on the high strength of glass magnesite, which reaches 16 MPa in bending. The sheets are easy to work with as they are easy to cut and do not crumble or crack.
Fixation can be done with nails, self-tapping screws, and also use an air gun. Cloths can be drilled. If you are interested in glass-magnesium sheets, the pros and cons of the drywall analog should definitely be considered. Among the positive features of the described material, one can also single out a very slight weight, which is 40% less compared to GKL.
Frost resistance and durability
If you need a material that has a high frost resistance, then LSU just meets these requirements. Its frost resistance is F50. The loss of mechanical strength in this case is not more than 3.5%. In the production process, fiberglass is used, which performs reinforcing functions. This provides excellent flexibility and prevents breakage during transport and duringinstallation work.
Durable and Green Quality
Manufacturers promise that LSU will last for 15 years or more. The final period of life will depend on the correct installation, as well as the features of operation. When using, you can not be afraid that the canvas can negatively affect human he alth. This is due to the fact that the sheets do not contain harmful ingredients such as formaldehyde, asbestos, phenol, etc. The material is not capable of causing allergic reactions, therefore it is classified as an ecological product that can be used even in medical and child care facilities.
LSU Disadvantages
If you decide to use a glass-magnesite sheet, the application, the disadvantages of this material is also important to find out. Among the latter, some features of low-quality glass-magnesite can be distinguished. When wet, it is able to release s alt, which can cause corrosion of the metal. Low-class material can be used exclusively for interior finishing work, which implies the absence of high humidity and sudden changes in temperature. It is impossible not to pay attention to the difference in quality depending on the class. When comparing the lines "Premium" with "Economy", the former has a more impressive content of magnesium oxide. Among other things, high-end goods are made using high-quality fiberglass mesh, in which the cells are smaller. This material has a denser structure and improved quality.fire resistance as well as frost resistance.
Quality glass-magnesite
If you are thinking about how to distinguish a quality glass-magnesite sheet, then you need to pay attention to the color, which should be beige or yellowish. The edges of the material should not be brittle, and the water should not become cloudy after exposure to the sheet.
