Starting repair work involves searching for materials, deciding to hire a team, or relying on your own. And even if it was decided to improve your own home yourself or the utility room needs to be repaired.
In any case, you will have to watch master classes and get acquainted with the advice of experts. After all, the microclimate in the room will often depend on the chosen material.
And then a fair question arises: which material will be better for cladding indoors or outdoors. The sheathing is not the final layer; carpet or linoleum is often attached to it without any problems, tiles or tiles are laid, wallpaper is applied and paint is applied.
First of all, various similar building materials are used for insulation, sound insulation and moisture absorption. Let's compare the advantages of gypsum fiber sheets and oriented strand board.
GVL or OSB
Each of the materials is environmentally friendly and natural products. However, they have completely different characteristics and properties. GVL are sheets of building gypsum that are reinforced with cellulose. Thanks to this technique for creating this building material, it is quite strong, but fragile. Gypsum fiber also perfectly blocks noise, retains heat and has a marked moisture-resistant appearance. Uses: wall, ceiling, floor, exterior cladding and partitioning. At the same time, they GVL burns very poorly. It is suitable for apartments and houses, and for public premises. But all these properties affect the high price of the material.
The second material, OSB, is several sheets glued together, the composition of which is one hundred percent natural, wood chips. They are pressed and glued together using resin, artificial wax, and boric acid. It is important that for external or internal cladding, the slabs differ in the pressing method. For external ones - longitudinal chips, for internal ones - transverse. These boards have different markings, including OSB, which can withstand humidity conditions.
Due to its composition, the price of OSB is significantly lower than that of GVL. Particle boards are just as durable. They are distinguished by their quality of workmanship and pleasant appearance; there will be no unpleasant odor in the room due to the minimal use of synthetic adhesives. They weigh little, so it’s easy to work in any plane. And you have to try really hard to break the slabs.
These slabs, like gypsum fiber boards, can be processed without difficulty. The issue of unwanted residents among the shavings should not bother the consumer. Thanks to special processing, this is impossible. These slabs can also be used to cover walls and can become the basis for laying roofs and floors as an intermediate layer.
There are some points that can be decisive when choosing a material:
- it is not easy to lay tiles or tiles on OSB boards;
- the surface of oriented strand boards is not perfectly flat compared to gypsum fiber board;
- chipboards, of course, are quite flammable;
- moisture-resistant properties are still different and preference is given to GVLV.
GVL or SML
Let's consider another option for replacing GVL with SML. SML is a glass-magnesium sheet; the material also has many other names, but they are all the same thing. It is a building material that is created on the basis of magnesium binder. Do not worry about its composition, it is safe for humans and is widely used for finishing residential and public premises. Magnesium glass sheets have a main advantage over other finishing materials - resistance to fire.
LSU is used for covering walls, floors and ceilings, and creating partitions. The same can be said for GVL. However, manufacturers often “chemically” change the composition of these building materials. Therefore, experts recommend buying only if there is detailed labeling and a verified supplier. Each of the materials is practically not afraid of fire; GVL and SML are often used for cladding elevators, for example.
The price also varies, GVL is much more expensive. LSU is characterized by high fragility; when working with it, a lot of debris is generated. Difficulties may arise when laying the finishing layers of tiles and wallpaper.
GVL or SHG
GSP is gypsum particle boards or sheets that are used only for interior decoration. They can be used to cover walls, floors and ceilings. The composition allows us to call it environmentally friendly and fire resistant. The shavings are the main element and are bound with building plaster.
GSP can withstand damp rooms quite well only if it is supplied periodically. It is also quite durable. External noise passes through it with difficulty. Thanks to the gypsum base, it easily absorbs and releases moisture when necessary. Thus, like GVL, it is able to create a comfortable microclimate in the room. It is easy to work with gypsum particle boards, saw, cut and apply any finishing layers.
It has an ideal, flat surface, like gypsum fiber board. If large loads are planned, then GSP is recommended for cladding. Its price is much higher than GVL.
GVL or DSP
DSP is a cement-bonded particle board. Its composition is quite simple:
- wood shavings;
- cement;
- special chemicals additives to reduce the influence of wood on cement.
This building material is extremely durable, breathable, non-flammable, does not allow sound to pass through, is waterproof and is practically impossible to rot. It is suitable for external and internal cladding of rooms, walls, ceilings, floors, and the base for roofing.
Due to its high density, it is a fairly heavy material, and working under the ceiling is no longer as easy as with gypsum fiber board. It has a low level of flexibility, and is not a fragile building material. Despite the high resistance of GVL to moisture, cement-based CBPB is better. The price of cement particle board is cheaper than GVL.
GVL or plywood
Plywood is multilayer sheets based on a special veneer that is glued together. The number of layers may be different. There are painted moisture-resistant sheets. Used in residential premises and frequent use.
The sound insulation properties are much lower than GVL, but at the same time they are several times stronger. When producing plywood, there is no strict monitoring of the ideal sheet thickness along the entire perimeter. When working with it, a lot of chips fly away. Not bad for leveling the floor; professionals even prefer plywood over gypsum fiber board. The price of gypsum fiber is much higher due to the composition and production method.
Do you know the difference between gypsum plasterboard, gypsum plasterboard and SML.
The article will help you decide on the choice of primary finishing material for walls and identify the differences between such popular materials as.
SML (glass magnesite sheet.
GKL (plasterboard.
GVL (gypsum fiber sheet.
Today, Chinese manufacturers offer another new sheet coating product - glass-magnesite sheet. The consumer is only at the stage of studying an alternative option for plasterboard sheets. His wait-and-see attitude is dictated by ignorance of the true qualities of the new product. In Asian countries, SML is a leader among similar finishing materials in construction work.
Glass-magnesite sheet (FMS) is a new product on the construction market.
LSU consists of finely crushed wood chips, magnesium chloride and oxide, and composite binders. All components are reinforced with fiberglass mesh. Glass and magnesium composition are the basis of LSU.
Properties of glass magnesite sheet.
LSU is characterized by such an attractive property as increased resistance to combustion. No other similar material has such a high fire resistance coefficient. Also, glass-magnesite sheets are perfect for finishing wet rooms (basement, bath) as they are famous for their high moisture resistance.
This is what a glass magnesite sheet looks like.
They retain their shape and their original properties at such humidity levels that other materials begin to delaminate and swell. Thanks to these important qualities of LSU, experts recommend glass-magnesite sheets not only for interior, but also for facade decoration.
During experimental testing, SML showed the highest result. After being in water for 100 days (!), the glass-magnesite sheet did not change at all. Therefore, this finishing material is recommended for finishing swimming pools, public and private saunas and basements. Low susceptibility to fungal formations (mold) only confirms the use of LSU for finishing wet rooms.
Glass-magnesite sheets are perfect for people who are inclined towards environmentally friendly products. LSU does not contain and does not emit harmful substances when heated, such as resins, phenols, adhesives and asbestos.
Using LSU in building a house.
The combination of flexibility, strength and lightness is an important characteristic of LSU. Thanks to the glass-woven reinforcing mesh, the glass-magnesite sheet can be bent over a large radius without mechanical damage. The plasticity of LSU is important when finishing uneven surfaces. Therefore, the new material is a worthy competitor to its fragile brothers: drywall and gypsum fiber. And glass-reinforced sheets are 40% lighter than plasterboard sheets. Structures made from SML are light, almost weightless, allowing you to create stepped ceilings with complex elements.
Video review of LSU.
This useful video will help you understand why glass-magnesite sheets are better than plasterboard, fiber cement boards and cement shavings. A new generation material made from fiberglass, magnesite and sawdust provides the highest performance characteristics.
SML is used for the construction of interior partitions, for multi-level ceiling and wall structures. Building elements made from SML do not require priming. Partitions and walls are ready for painting, wallpapering, and tiling. Different sheet densities are intended for different needs. For example, for facade finishing, Premium class material is used with a density higher than 0.95 grams per cubic centimeter, and 1st grade sheets have a lower density and are intended for interior construction.
Installing LSU is more labor-intensive than installing drywall. If you tighten a glass-magnesite sheet with screws or staples, this will lead to cutting of the reinforcing fiberglass layer. As a result, the material will lose the ability to be held in place by a screw or bracket.
Glass-magnesite plates (sheets) are easy to saw, cut, plane and glue. Installation work is carried out using a pneumatic gun and an electric drill. When cutting the material, no harmful dust is released.
As you can see, you can cut a sheet of LSU with the most ordinary knife without any effort.
The service life of the plates reaches 15 years. During this time, manufacturers guarantee complete preservation of the original appearance. The material does not crumble and is not susceptible to other destructive effects. Insects and mold do not grow in the slabs. When working with LSU, you must use gloves. This will help avoid irritation caused by fiberglass particles.
In Russia, the leading place in the construction industry is occupied by plasterboard sheets. This material is excellent for finishing work. With its help, you can level the ceiling and walls, divide the room with a wall, and bring design ideas to life.
Plasterboard sheet.
The inner layer of the sheet consists of 93% gypsum. The outer layer is made of cardboard, making up 6% of the total volume and 1% is organic matter.
Properties of gypsum plasterboard.
Drywall has excellent soundproofing properties. Some lovers of silence cover completely straight walls and ceilings with plasterboard sheets just because a noisy tenant lives next door. Fire resistance is another positive characteristic of gypsum plasterboard. Drywall has such an important quality as complete drying. The plasterboard coating both absorbs moisture and releases it without subsequent damage to the appearance.
Plasterboard sheets.
Builders are especially attracted by the ease of installation (dismantling) of plasterboard sheets. Constructions made from this material allow you to implement design ideas and hide all communications in partitions and under the cladding. Built-in lighting, niches, arches, columns and other decorative elements can easily be made using gypsum boards. All imperfections made during construction are easily hidden with plasterboard sheets.
An example of home construction of plasterboard walls with your own hands.
Drywall is a fragile material. Often breaks during transportation. GKL also easily absorbs moisture, so it is completely unsuitable for wet rooms, or special plasterboard sheets (GKLV) are used. Another significant drawback is that over time, the gypsum in the slabs breaks down and turns into dust. Therefore, allergy sufferers and asthmatics should take into account this property of gypsum and take appropriate measures: for example, reliably insulate drywall with special decorative coatings.
Plasterboard structures produce the sound effect of emptiness - you just need to knock on them a little. To avoid such trouble, professionals prefer to use stone wool, which is placed in partitions and columns. This measure solves this problem. But nothing can hide the fragility of plaster and cardboard.
Drywall is not suitable for finishing industrial premises, since large crowds of people lead to a colossal load on the walls. Thin walls cannot hold out for long under such pressure. Another thing is lightweight partitions and structures for living quarters. But in residential buildings, another need often arises: to hang or attach something to the wall.
The main thing is to choose the right fastening material and act according to the technology. It is necessary to take into account weight, distance between fastenings and other parameters. Heavy objects are secured to the wall using bolts that go through both the drywall and the main wall. Only then can reliable fastening be ensured.
Video on installation of plasterboard structures.
As this video shows with no small amount of humor, before you begin installing plasterboard sheets, you must carefully prepare and treat all surfaces. In addition, it is also important what kind of tools are used.
Types of plasterboard sheets.
Drywall is divided into:
fire-resistant (GKLO.
moisture resistant (GKLV.
combined type.
decorative type.
You can always choose the material that best suits the room.
GKLO is a fire-resistant plasterboard sheet coated with a fire-resistant compound. Gypsum board is intended for rooms with an increased risk of fire. The difficult flammability of the material can save lives in a critical situation.
An example of GKLO from the world famous German company Knauf.
GKLV is a plasterboard sheet with increased moisture resistance, containing antibacterial components and inhibiting the formation of mold. This drywall is equipped with special additives that prevent high moisture absorption.
Using gypsum boards for the attic ceiling.
Decorative leaf.
Decorative plasterboard sheet is an innovation in the construction market. The board made of cardboard and gypsum has a decorative layer. The coating of the sheet can imitate wood, marble or other characteristic pattern, similar to natural and artificial origin.
Sheet of decorative plasterboard.
Installation of decorative plasterboard requires special care. The seams are fitted end to end and sealed with decorative elements. Scrupulous study of the rules for installing exclusive plasterboard boards guarantees quality for many years. Decorated plasterboard sheets are resistant to discolouration for 10 years. During this period, the panels can withstand chemical and mechanical stress without loss of appearance (with proper handling.
KGP PS is a combined plasterboard sheet with insulation. The expanded polystyrene layer guarantees additional insulation to the main walls. KGP PS is used for internal and external insulation.
Plasterboard sheet with insulation.
Gypsum fiber sheets.
GVL is a gypsum fiber sheet reinforced with cellulose fiber and has greater strength than plasterboard. This is a hard material that absorbs noise well.
Gypsum fiber sheets are increasingly popular in construction.
Resistant to burning. During operation, a small percentage of dust is released (unlike drywall). Moisture-resistant GVL is intended for wet rooms.
Hello, dear Reader!
Nowadays in construction and renovation there is a tendency to move from “wet” methods to “dry” ones, for example, instead of a thick layer of plaster, leveling the walls with plasterboard.
Today we’ll talk about glass-magnesium sheet - a relatively new material that is just suitable for such “dry” methods.
LSU panels: what is it? Glass-magnesium, or glass-magnesite, sheet (stroylist, novolist) is one of the new construction and finishing materials that tried to replace plasterboard, but has not yet replaced it. Let's figure out why it wasn't replaced.
It contains caustic magnesite, magnesium chloride, expanded perlite and fiberglass. There may also be shavings present. The technical characteristics of LSU allow it to be used both for construction and finishing. Glass magnesium is not afraid of water, fire, does not emit harmful substances when heated, and retains its properties at temperatures down to -50°C.
It does not crumble and is much stronger than gypsum-based building materials. Standard size - 3000*1200 or 2440*1220 mm, thickness - 3, 6, 8, 10, 12 mm. Glass-magnesium sheets are produced in the categories “Standard” for interior decoration, “Premium” with increased moisture resistance and strength for cladding facades and construction.
The panels are also produced in the “Superpremium” category - they can be painted, laminated, covered with veneer, and in the “Interior” category - these are ready-made painted SML panels for interior decoration.
Novolist can replace plasterboard in interior decoration, as well as DSP and GVL in construction. LSU is used to create, for example, bases for floors and cladding.
GVL, TsSP or SML
Which is better, GVL or SML? They are comparable in cost and both are strong enough for their purposes. But there are differences, mainly in favor of glass magnesium.
- Glass magnesite can be used in damp rooms; it practically does not absorb water and does not swell from moisture.
- To cut gypsum board you need a special jigsaw; in the case of glass-magnesium, you can get by with a drywall knife.
- Stroylist does not require pre-treatment before gluing wallpaper.
- Ceramic tiles do not adhere well to GVL.
- Gypsum fiber can emit dust, LSU does not emit anything, and is safe for allergy sufferers and people with asthma.
- The magnesite plate is stronger, so it can be taken with a smaller thickness: 8 mm instead of 12 mm gypsum board.
- Glass magnesite is more flexible.
DSP is used for partitions, cladding, floors, roofing bases, for frame structures, that is, in the same place as LSU. Both of these materials are fireproof, resist fungi, mold and insects, are environmentally friendly and are not afraid of frost.
What to choose - SML or DSP?
- With DSP, problems sometimes arise when puttying joints - the dimensions of the boards change slightly with changes in humidity.
- It is important that glass magnesium is much lighter than CBPB.
- DSP bends poorly, making it difficult to finish structures of complex shapes.
How to install SML panels?
Usually, the supporting structure is first made from a profile. In this case, there should be 60 cm between the vertical profile posts if we are covering the wall. For a suspended ceiling, the distance between the profiles should be 40 cm.
If the panels are wet, they need to be allowed to dry first - wet ones are more fragile. For greater strength, it is better to place the panels so that the fibers are vertical. A gap of half the thickness is left between the sheets.
This material is easy to process: drill, cut; a regular drywall knife is suitable for this. During cutting, it does not crumble or crack, but if you cut with a jigsaw, dust appears, so it is recommended to work in a respirator.
For fastening, special self-tapping screws with notches on a countersunk head are used, the same as for drywall. It is better to attach the back side to the profile. The back side is the one on which the reinforcing mesh is visible.
LSU as a building material
Walls made of magnesite slabs can be finished in a variety of ways: they can easily withstand ceramic tiles, and they can be coated with plaster and putty. Glass magnesium can be used as a base for floors, roofs, floor leveling, and suspended ceilings.
But magnesite is used not only for finishing; it is used to produce SIP panels from which houses are built. These sandwich panels use new sheet metal and rigid insulation, such as polystyrene board, mineral wool, or a combination of both.
An important advantage of such houses is their rapid construction. And SIP panels made of magnesite allow you to add to this advantage all the advantages of glass magnesite. Sandwich panels with dimensions of 2440*1220 mm and thickness of 224 or 174 mm are produced.
They are called stone panels because they are heavier than regular OSB (oriented strand board) SIP panels. In addition, ready-made kits are sold from which you can assemble a house. SML panels are used as permanent formwork for lightweight concrete. Building blocks with lightweight concrete fillers are also produced.
How to choose
If you decide to use new sheet for the construction or decoration of your home, the question arises, how to buy really high-quality magnesite?
- Firstly, you should not spare money - it is better to choose the “Premium” category than “Economy”. More expensive stelomagnesium is not only more durable, but also definitely safe - cheap ones may contain harmful additives such as asbestos.
- Secondly, some signs indicate quality:
- First of all, pay attention to the edges - they should not be uneven or brittle.
- If you run your hand over the surface, you should not feel any dust.
- If it is possible to immerse a piece of glass magnesium in water, do so. If the water becomes cloudy, this is a sign of the presence of gypsum, which means it is of poor quality.
- Look at the reverse side - the non-woven base also gives out poor quality and reduces fire resistance.
- Material from a responsible manufacturer is clearly labeled.
What is the price?
The cost of one sheet, depending on the thickness, is from 800 rubles for the “Premium” category and from 600 rubles for the “Standard” category. If the price is lower, you should think about quality. SIP panels based on glass magnesite cost 3990-4200 rubles per piece. The price of a house kit made from “stone panels” starts from 300 thousand rubles.
The appearance of serious new products among finishing materials on the market is a rare occurrence. Manufacturers do not particularly bother with development and research; with the current boom in construction and renovations, this is not necessary.
There is nothing left lying around in warehouses and shelves, and therefore it is enough to slightly change the properties of the material - add a new element to the paint or dry mixture and a new material is ready!
But there are exceptions. Glass-magnesite sheet (GML) cannot be called a fundamentally new development, but its large-scale production started recently. Therefore, we can call it a new sheet material for finishing work.
This material, of course, has not received the same widespread distribution as plasterboard (gypsum board), and since its cost is higher than that of gypsum board, it is unlikely to displace it from the market, but better characteristics and a wide range of possibilities for the use of LSU, at a minimum, deserve close attention.
It is no coincidence that we compare LSU with gypsum board; at the moment, finishing work is most often carried out using drywall.
Finishing rooms with sheet material (subsequently decorative processing) has many beneficial advantages for both contractors and customers. Working with sheet material does not require high qualifications; installing ceilings and covering walls takes little time; the surface of the sheet material is initially suitable for wallpapering, painting and puttying...
However, the use of gypsum boards still has limitations:
- GCR cannot be used for exterior work, but only for interior decoration.
- Despite the fact that gypsum plasterboards exist for wet rooms, contact with water or a fairly long stay in a humid atmosphere deforms even “moisture-resistant” material.
- Drywall is heavy and fragile, it requires care.
- GK sheets, although non-flammable, are destroyed under the influence of elevated temperatures.
Most of these disadvantages do not apply to LSU, and it is quite possible that this material will supplant gypsum plasterboard in a number of areas of application.
Characteristic
SML is a unique material for finishing rooms with high or high humidity, consisting of natural materials and reinforcing fiberglass, which as a result makes it absolutely impervious to moisture.
It follows that with the help of LSU it is possible to carry out external finishing work. For example, you can cladding facades and their elements, or LSU can be used in the construction of ventilated facades.
Another advantage of glass magnesite is its good resistance to high temperatures - according to the characteristics, this material can withstand heating up to 1200 degrees without deformation or destruction.
This allows it to be used for finishing fireplaces, baths, saunas, and fire exits.
Elasticity and strength, excellent adhesion to almost all finishing materials - paints, adhesives, putties, and high manufacturability - are very easy to process, the sheets can be used in almost all areas - from creating permanent formwork to furniture production.
At the moment, of course, it is too early to talk about the areas of application of the material, it has appeared too recently, but its technical characteristics inspire respect.
Structures made of glass-magnesite are assembled in exactly the same way as gypsum plasterboard, on the same profile, rack-mount or ceiling, but the high range of thickness requires the use of different materials for different purposes.
LSU is only significantly inferior to GKL in one important indicator - price.
Gypsum fiber sheets and glass magnesium sheets have many similar characteristics and applications. The high strength of these sheet materials makes it possible to make floorings from them (prefabricated dry screeds), to cover attic floors and wall surfaces with them, and to create separate structures, including interior partitions. In addition, some moisture resistance of glass-magnesium sheets makes it possible to use them in damp rooms. Read more about the characteristics of GVL and LSU, their features...
Features of GVL
Gypsum fiber sheets (GFS) are produced by mixing and pressing cellulose and gypsum fibers. The result is wood-reinforced plaster.
Due to the internal stiffening rods, the gypsum fiber sheet is much stronger than plasterboard in compression. T Also, a dowel in a gypsum fiber sheet can withstand a load of up to 50 kg, and a screw – up to 30 kg.
The strength of GVL is also achieved due to the significant density of the material - 1250 kg/m³.
GVL has excellent resistance to fire, so it is used in the construction of premises with increased requirements for fire protection. The cardboard on top of the sheet (if any) is only charred when exposed to flame.
The low heat absorption coefficient makes the material warm to the touch.
The high hydrophobicity of gypsum helps maintain constant humidity in the room. When humidity increases, gypsum quickly absorbs excess moisture, and when it decreases, it releases it back into the room.
Application of gypsum fiber sheets
Gypsum fiber sheets are used quite widely. They are primarily used to line wooden walls in order to increase their resistance to fire and prevent air permeability. Suspended ceilings are made from them, and other walls are sheathed with them. Also, the sheets are laid at the base of prefabricated floors, and any floor covering is laid on top - even ceramic tiles, or a water-heated floor with a dry screed is made. More details 
In addition, it is necessary to note the advantages that gypsum fiber sheets provide in the construction of a prefabricated floor.
— there are no wet processes, the labor intensity and installation time of the subfloor are significantly reduced.
— the structure turns out to be practically “weightless” compared to a concrete screed of the proper thickness, which is especially important when installing on the ceiling.
— the heat and sound insulation characteristics of the floor are increased.
A moisture-resistant type of gypsum fiber sheets - GLVL, which has a special impregnation, is used for interior decoration of bathrooms.
Installation is similar to the installation of any sheet facing material. The sheets are mounted on a lathing made of wooden beams or metal profiles. The seams between the sheets are sealed with putty.
There is no need to apply a primer on GVL, since the material is initially impregnated with a composition similar to the primer.
Seam sheets are mounted as standard.

The price for a gypsum fiber sheet is approximately $$$
Features of glass-magnesium sheets
Magnesium glass sheets, abbreviated as GSM, are made from fine wood chips, perlite, magnesium oxide and magnesium chloride. The name of this building material in Russian has many synonyms:
- magnesite, magnesite plate, glass magnesite, magnetite, construction sheet, etc.
Glass-magnesium sheets are reinforced with a fiberglass mesh on both sides, which gives them increased strength and the ability to bend without breaking with a radius of curvature of approximately 3 m.
The main distinctive qualities of glass-magnesium sheets, in comparison with other building sheet materials, are as follows:
- increased strength, an 8 mm thick sheet of medium density approximately corresponds to 12.5 mm of plasterboard;
— significant moisture resistance;
— fire resistance, does not ignite up to 1200 degrees;
— frost resistance;
— flexibility, possibility of use on uneven grounds;
— chemical resistance to aggressive environments – alkalis, acids, gasoline, oils;
- antiseptic and dirt-repellent properties.
In fact, glass-magnesium sheets are a universal base for finishing coatings.
Suitable for finishing facades and for cladding wet rooms - showers, bathrooms, kitchens, swimming pools.
The antiseptic properties of the material prevent the appearance of fungus and mold in damp places. This building material can be mounted directly on main walls, as well as interior partitions or floor subfloors can be made from it.
How glass-magnesium sheets are mountedInstallation 
Glass-magnesium sheets are mounted using a similar technology to plasterboard and other sheet materials. Fastening is carried out with screws, dowels, nails on a wooden or metal sheathing.
If work is carried out with a denser type of material - over 1200 kg/m3, then it is recommended to pre-drill holes for installation. If non-dense (most popular) sheets of 980-1050 kg/m3 are used, then drilling is not necessary.
The sheets are folded when dry. Cutting is done by creating a notch on the fiberglass reinforcement on one side, followed by breaking along the notch. When cutting, the material does not crumble.
On the mounted surface, the joints between the sheets are filled with acrylic or silicone putty.
Technical characteristics of glass-magnesium sheets
The technical characteristics may vary over a wide range. Depending on the so-called class of material - “Premium” ... - “Economy”. In economy class, it is possible to partially replace magnesium with chalk, asbestos, etc., which affects the physical characteristics and durability of the material.
The main supplies to the market were previously carried out from China, mainly Economy class, which affected the popularity of this building material. But recently, the production of high-quality magnesite slabs (glass-magnesium sheets) has been established in our regions.
The most common sheet size is 1.22x2.44 m
Possible thickness – from 4 to 15 mm
Density - 800 - 1400 kg/m3, According to the Chinese classification, glass-magnesium sheets are divided into a number of classes depending on density, designated by a letter index - A, B....
Thermal conductivity, W/(m C) – 0.08 – 0.15
Vapor permeability, mg/(m hour Pa) - 0.11 - 0.14
Temperature coefficient of linear expansion - unchanged.
Flammability group: NG (non-flammable)
The price of one sheet 122x244 cm (8 mm thick) is approximately $$$$
