LSU panels are distinguished by their strength and excellent water resistance. The material is very similar in its properties to drywall, which makes it very competitive in the finishing market. Buying a constructionist will not be difficult, since many firms are engaged in its implementation.

The popularity of glass-magnesium plates is due to the excellent characteristics, ease of processing and reasonable price. Although the material can be easily cut with a jigsaw, file, plasterboard knife and other similar tools, this does not mean that magnelite is fragile. On the contrary, LSU plate is durable and flexible. In addition, virtually no dust or debris is generated during material handling.

LSU panels are produced from magnesian binder and fiberglass mesh, which performs reinforcing functions. Magnesia binder is a type of concrete that results from the interaction of magnesium chloride and caustic magnesite. The classification of LSU panels is carried out depending on the sheet thickness and individual quality characteristics. There are also LSU options that are used as decor. This type of panels does not require additional finishing. Decorative sheets are available on the market in a wide range of colors.

Helpful advice! When choosing a material, you must be guided by the method of use. For external use, LSU premium is best suited. The cost of such panels is several times higher than the price of ordinary ones, but the quality characteristics of glass-magnesium sheets allow you to calmly endure the influence of natural factors.

Advantages and disadvantages of glass-magnesium plates

More recently, drywall had no alternatives on the building materials market. But with the advent of glass-magnesium sheet, which is more technological, the situation has changed. The high level of performance is due to the composition of the material, which includes natural and natural ingredients. Excellent strength values, equality of structure density are achieved through firing at a temperature of 2000 ° C.

LSU boards have special advantages over other similar materials:

  1. Versatility. The material is used in all types of finishes: slabs with a thickness of less than 6 mm are placed on ceilings, sheets of 6 mm are suitable for walls, a 10 mm construction sheet is laid on the floor, magnelite with a thickness of 12 mm or more is used to create facades and interior partitions.
  2. Strength. Magnelite plates can easily withstand any mechanical damage.
  3. Density. The budget material has a density of about 1 kg per m³, luxury sheets - more than 1.5 kg per m³.
  4. Ease of processing. Manelite is easily cut, does not crumble, does not break.
  5. Fire safety. Withstands temperatures over 1000 ° C, prevents the spread of fire.
  6. Moisture resistance. The board does not absorb water, does not swell, does not swell, does not change shape, and also does not lend itself to rotting, is not afraid of mold and mildew.
  7. Environmental friendliness. Does not cause allergies.

Also, the disadvantages include the price for LSU sheet. But the cost of the material is fully compensated by the excellent technical characteristics and parameters.

Glass-magnesium sheets: technical characteristics of LSU plates

Usually a magnesite slab consists of the following materials:

  • expanded perlite - 5%;
  • magnesium oxide - 40%;
  • magnesium chloride - 35%;
  • small wood chips - 15%;
  • fiberglass - 1%.

Synthetic fibers are added to the composition as additional binders, and perlite significantly increases the sound insulation characteristics. The main properties of glass-magnesium sheets: strength, hardness, fire resistance and moisture resistance. The material is resistant to fungi, mold, and is able to keep its shape for a long time under the influence of a humid environment.

As for strength, the material is quite dense, with a homogeneous texture, it does not delaminate during operation. Due to the increased density characteristics, it has increased wear resistance to mechanical damage and deformation loads.

LSU sheet: characteristics and features of the use of the material

Glass magnesite sheet LSU is very easy to process. The initial edge of the slab is easily cut with an ordinary construction knife, after which the sheet must be bent in the opposite direction in the place of the cut made. Then the bend is similarly cut.

According to the criteria of flexibility, LSU board resembles drywall, plywood, OSB, DSP panels. Without humidification and heating, magnelite practically does not have this indicator.

Due to the high level of moisture resistance, glass-magnesium plates can be used for the treatment of rooms exposed to humidity: baths, saunas, shower rooms, swimming pools, as well as for any outdoor finishing work. This construction leaf does not absorb water and does not change its structure, does not swell, does not crack from dampness during the operating period. According to laboratory studies, the premium magnesite slab does not change its properties even after 100 days in water.

It should be noted the environmental friendliness of LSU sheets. For the production of the material, exclusively natural and natural substances are used that do not harm humans and the environment. Magnesite slabs do not include asbestos and other harmful components.

Glass-magnesium plates are a very popular material today. This is primarily due to the ease of installation. Magnelite is ideal for installation on both plasterboard profile systems and wooden frames. Fastening with self-tapping screws MN or TN 25-65. Pointed point screws SN and SB 25-40 can also be used for these purposes.

In the case of using premium grade A boards, you need to make light drilling under the screw head. For other types of this material, namely for classes B - G, this can be omitted, since the screw fits perfectly into the surface of the magnesite sheet. The exceptional strength of LSU slabs allows mounting even with ordinary nails and a pneumatic gun, which is absolutely unacceptable in the case of drywall application.

Due to the nature of the magnesite surface, there is no need for priming the surface before filling.

Due to the nature of the magnesite surface, there is no need for priming the surface before filling.

The use of magnelite can significantly save money and time, since the surface of the material does not require priming before filling, tiling or wallpapering. And the sound insulation of a room lined with magnesite sheets doubles.

Helpful advice! It is possible to cover the LSU board with vapor-permeable dyes. If you apply a moisture-proof paint, the top layer can swell and crack over time.

Variety of scopes of glass-magnesium sheets

Most often, glass-magnesium sheets are used to perform the following types of work:

  • all types of exterior wall decoration, including stone cladding, ceramic tiles or stucco;
  • interior wall treatment for painting, wallpapering, tiling and clapboard or paneling, puttying;
  • elimination of uneven surfaces of walls, ceilings and floors;
  • creation of interior partitions, regardless of the finish;
As a rule, LSU sheets are used for interior finishing work.

  • processing the floor for laminate or parquet;
  • any architectural ideas for space decoration;
  • finishing of baths, saunas, bathrooms and pools;
  • creation of banners, billboard advertising;
  • arrangement of protective fireproof cladding near the centers of spontaneous ignition;
  • soundproofing works.

Useful advice! If plaster will be laid on top of the panel, then it is better to install magnelite with the back (rough) side outward. This will ensure a tighter adhesion of the cladding to the surface of the slab.

How much does it cost to build a house with LSU panels

Glass-magnesium panels are one of the most popular materials for building a modern home. It can be used all year round, and frame-panel construction does not require special foundation construction. The energy efficiency of such buildings is much higher, and the construction costs are lower, because no special equipment is required to transport the material.

Tips for choosing a quality glass-magnesium plate

Glass-magnesium sheets (LSU) have a significant number of reviews, but not all of them are positive. But the popularity of the material does not fall, but on the contrary, the construction of many important state facilities is not complete without the use of magnelite. The main problem is that the material is missing any markings. Unscrupulous manufacturers take advantage of this, violating the technology for the production of plates.

There are negative reviews about glass-magnesium sheets due to an incorrect definition of the scope. In addition, most consumers believe that LSU panels are a complete replacement for drywall. But this is not the case, because only some types of stectomagnesium sheet can be fully used instead of gypsum boards.

Since the price of a magnesite slab is quite high so as not to waste money, it is important to know how to distinguish a quality panel from a semi-handicraft material made from cheap components:

To choose high-quality material, you need to read the recommendations of specialists

To choose high-quality material, you need to read the recommendations of specialists

  1. Material color. LSU board of excellent quality has a beige or yellowish tint. Poor quality material is usually white or light gray.
  2. Slab edges. Magnelite of poor quality has rough and brittle edges.
  3. Leaf base. Low-quality construction sheet is covered with non-woven fabric on the back. This reduces the refractoriness of the material.

Useful advice! To check the quality, you can put a piece of glass magnelite in water for a couple of hours. If the stove is of high quality, the water will not become cloudy.

Interior or exterior wall decoration is constantly in great demand. Thanks to this, modern building materials will always appear on the market. At this time, the latest finishing materials, including glass-magnesium sheets, are very popular.

Thanks to modern production technology and exclusively natural ingredients, magnesite board pushes materials such as drywall and plywood into the background. Excellent technical characteristics of glass-magnesium sheets (LSU), price are the main advantages of this material. The peculiarity of such a builder is that one side is smooth and polished, and the other is embossed.
