For cladding walls, installing partitions, assembling decorative structures, installing ceilings, insulating and remodeling different types drywall. Plasterboard for the ceiling simply cannot meet the relevant requirements when installing, for example, partitions. Drywall is produced by different companies and we will have to figure out which drywall is preferable and which manufacturers can be trusted.
In Russia, plasterboard sheets are produced by both Russian and foreign manufacturers.
The sales leader is a German company Knauf, which has more than ten factories in Russia for the production of building materials and all types of plasterboards.
In addition to the Knauf company, companies such as Lafarge Group(Poland) and Gyproc(Scandinavia).
About 10% of plasterboard on the Russian construction market is imported by a French company Compagnie de Saint-Gobain SA. Trademarks cooperate with her Rigips, Nida Gips And Giproc.
Only 20% gypsum board per Russian market supplied by Russian manufacturers. Drywall from companies such as OJSC "Gypsum", JSC "Sverdlovsk Gypsum Products Plant", OOO "Arakchinsky gypsum" etc. are actively used in finishing and construction in Russia.
Of the Russian plasterboard manufacturers, it is worth noting the following companies:
- JSC "Gips"— Volgograd company that produces Volma brand plasterboard sheets. The company produces high quality gypsum boards at a competitive price.
- Gifas– industrial group of OJSC Sverdlovsk Gypsum Products Plant. Thanks to high-tech equipment, the quality of this brand is also not inferior to foreign analogues.
- Abdullingips– trademark of Arakchinsky Gypsum LLC, Kazan. The company produces standard and moisture-resistant plasterboard at a relatively low price than other Russian brands.
- Golden Group Gypsum– trademark of LLC “Plant for the production of plasterboard Golden Group Gypsum”, Tolyatti. The company produces sheets of standard and moisture-resistant plasterboard on modern French Lafarge equipment. The products have decent quality and low cost.
Also among the manufacturers of gypsum plasterboards in Russia one can note “Gippolymer” (Perm) and “Combine of Building Materials and Structures” trademark Utah Gtps (Oktyabrsky city, Bashkortostan river). The products of these manufacturers have high quality and the lowest price in the Russian Federation.
How to choose
The choice of drywall is determined primarily by the conditions of use and the characteristics of the room. In addition, in order to more rationalize costs, it is important to know the size future design, since gypsum boards can now be purchased in different sizes.
High-quality drywall has a white core.
When choosing drywall, you should pay attention to its storage conditions and the quality of the material.
Basic criteria for choosing drywall:
- Type of work performed;
- Dimensions, weight and type of sheet edge;
- Company manufacturer;
- Price.
Tips for choosing drywall:
- It is better to buy the material in large construction stores with sufficient turnover, then there is more guarantee that the gypsum board has not been stored for too long.
- Before making a purchase, you should evaluate the storage conditions of drywall.
- Visual inspection of gypsum boards – required condition before the purchase. Care should be taken to ensure that there are no dents or damage to corners, edges and surfaces. Deep scratches on cardboard carry the risk of breaking the sheet in unnecessary places. If there are traces of moisture on the material or the paper in some places has begun to move away from the core of the sheet, it is better to refuse the purchase. Drywall sheets must be smooth, without bending.
- It is important that the sheets are cut evenly, at right angles to the edge in the factory (this is necessary for correct joining).
Which drywall company is better to choose?
In fact, the answer to the question: “Which brand of gypsum board is better to choose?” very simple. If the material is free from defects and damage, meets the basic selection criteria, as well as its purpose, then the manufacturing company, in fact, does not play a special role.
Many people believe that it is better to buy drywall from well-known companies that have proven themselves in the global construction market as manufacturers quality material. This is a misconception, since, first of all, the compliance of the sheets is important certain requirements. Sheets of the most famous brands may be damaged during transportation or stored in inappropriate premises, rendering them ultimately unusable.
Drywall from a local little-known company can be no worse in quality than material from world brands. However, such material is usually lower in price.
Choice for walls
For insulation or cladding of walls, as well as for the construction of interior partitions and vertical decorative structures, the wall type of plasterboard is used. The thickness of the material is 12.5 mm, while for other types of gypsum plasterboard used for other purposes, it is much smaller. However, practice shows that ceiling and arched plasterboard can also be used to level walls, but only if there is no high requirements to the mechanical strength of walls.
If you are going to build a partition, it is better to abandon unnecessary savings and purchase durable sheets of plasterboard for the walls, and if you plan decorative design with curved surfaces, it is better to use thinner types.
How to choose drywall (video)
Drywall - sheets consisting of two layers of construction cardboard, between which there is hardened gypsum “dough” with fillers. It is used for installing partitions and cladding walls and ceilings in residential and office buildings with normal and dry humidity conditions. Let's try to figure out which drywall is better.
Types of drywall: 1-Moisture-resistant or waterproof drywall (GKLV); 2- fire and moisture resistant plasterboard (GKLVO); 3- Ordinary sheet of drywall (gypsum board); 4- Fire-resistant plasterboard (GKLO).
Advantages of drywall:
- maintains the desired microclimate in the room;
- environmental friendliness: drywall is completely harmless and does not have a detrimental effect on human health;
- high sound insulation;
- the possibility of subsequent finishing with painting, plastering, tiles, wallpaper and other materials;
- low cost of plasterboard - allows it to be used even in low-budget construction;
- the ability to create structures of any complexity, including round ones.
Disadvantages of drywall:
- fragility: to embed large items and objects, it is necessary to additionally strengthen the frame of the entire structure;
- use drywall in rooms with high humidity is possible only if you create additional protection using special primers;
- When cutting drywall, you must wear a respirator and goggles, since when working with it, gypsum dust is formed, which is harmful to the mucous membranes and respiratory tract.
Types of drywall
Drywall is divided into ordinary, fire-resistant, moisture-resistant and moisture-fire-resistant. Installation work begins with the need to choose the right option.
- Ordinary (GKL) - used in rooms with dry and normal-humid microclimates, where there are no high requirements for moisture and fire resistance of materials.
- Fire-resistant (GKLO) - suitable for rooms with moderately humid and dry microclimates. It contains reinforcing components, which in the event of a fire prevent the flame from spreading.
- Moisture-resistant (GKLV) - used in rooms with normal and humid climates, for this it is treated with hydrophobic and antifungal compounds.
- Moisture-resistant (GKLVO) - combines the properties of GKLV and GKLO. It is used in buildings with dry, normal and humid microclimates.
When using GKLV and GKLVO, it is correct to protect the front side of the material with tiles, primer or paint. Which drywall is best to use in a particular case depends on the type of room.
Drywall is also differentiated depending on the type of edge, thickness and color. The thickness of the sheets can be from 6 to 25 mm, and the edges can be semicircular, round, thinned, or straight. Moisture-resistant sheets are usually blue or green, standard - gray, fire-resistant - red and gray.

How to install a plasterboard wall correctly
Position the wall correctly optimal thickness You can do it yourself from plasterboard. This kind of work only requires knowing the basic nuances. Most often, sheets with a thickness of 12.5 mm are used.
You will need:
- drywall;
- main profile;
- guide profile;
- Styrofoam;
- metal scissors;
- hammer drill with drills;
- screws, nails and dowels;
- building level;
- hammer;
- plumb line;
- putty knife;
- pencil.
Installing the frame
- To calculate the number of sheets of drywall and profile required to set up and build up the frame, you need to measure the opening in width and from floor to ceiling;
- The walls are leveled with mortar.
- On the surfaces of the walls, floor and ceiling, using a level, plumb line and pencil, you need to make guide marks.
- Profile guides are mounted on the walls and ceiling surface according to the markings: to do this, the profile is applied to the wall and, holding it, holes are drilled for fasteners and secured with self-tapping screws. Similar work is carried out on the floor and ceiling.
- The main profile is cut to the height of the wall being built and connected so that it snaps into place.
- The frame is erected: the assembled profile guides are installed in increments of 60 cm along the entire length of the wall and fixed with self-tapping screws.
- Cut guides from the profile for installation passing above the crossbar door and secure it with self-tapping screws.
- Before gluing drywall to the resulting frame, it is necessary to make electrical wiring and pipes.
Drywall installation work
- The sheets on one side of the wall must be properly secured with self-tapping screws onto the profile frame. The screws are screwed in at an angle of 90 degrees relative to the surface, the caps are recessed by 1 mm.
- Use a hacksaw to make a doorway in the wall.
- The partition frame is filled mineral wool or polystyrene foam. For high-quality sound and heat insulation of a room, it is necessary to ensure that the entire space is filled tightly.
- Drywall is secured with self-tapping screws on the other side of the wall.
- The joints are taped with a special perforated tape.
- Using a spatula, tightly putty the guide joints of the sheets and the recesses from the screws. After the putty has dried, it is sanded.
- A primer is applied to both sides of the wall.

How to make wall cladding with plasterboard
Drywall is often used to finish walls and ceilings. Installation of drywall is carried out before laying the finishing flooring. In order for the walls and ceiling to support the drywall, they must be strong and not delaminate. Drywall cannot be glued to plaster.
The room temperature must be maintained above 10°C. Before installation, drywall must be kept in the room being repaired for 2 - 3 days so that it accepts its air humidity and temperature. Which drywall is best to install depends on the climate in the room. In rooms with normal and dry temperature and humidity conditions, gypsum boards are installed. For rooms with high humidity, gypsum plasterboard is used.
Before work begins, the installation of electrical wiring and pipelines, which are planned to be hidden under the plaster, is completed. Distribution boxes need to be made protruding from the wall by about 20 mm.
Gluing plasterboard to walls and ceilings is done with putties and adhesives like Perlfix, Fugenfüller and the like. To improve the adhesion of walls that do not absorb moisture, they are treated with Betocontact primer or similar. Hygroscopic walls, for example, if wood was used for their manufacture, are treated with primers that reduce the absorption of moisture from the glue, such as Tiefengrund, Ricombigrunt.
On door and window lintels, behind kitchen sinks, washbasins and where you plan to attach heavy objects, you need to glue drywall over the entire surface, and not in fragments.

Options for gluing plasterboard boards
Scheme for applying adhesive for plasterboard walls. (and for smooth walls, b- for uneven walls)
A. If the unevenness is no more than 4 mm, the sheets are glued directly to the walls gypsum putty, for example, Fugenfüller. Putty is applied thin layer longitudinal stripes along the center and perimeter of the sheets.
B. If the unevenness of the walls is from 4 to 20 mm, the drywall is glued with Perlfix glue, applying it pointwise to the middle and along the perimeter of the sheets every 40 cm.
C. If the unevenness of the walls is more than 20 mm, strips cut from plasterboard 100 mm wide are first glued with Perlfix glue and plasterboard slabs are glued onto them with Fugenfüller putty.
Preparatory work
- The walls are hung with a level or plumb line and the magnitude of their unevenness and deviation from the vertical is determined.
- Using a plumb line, markings are made on the walls and ceiling.
- The walls are dried, roughness, oil and greasy spots and remove dust.
- Walls that do not absorb moisture must be treated with Betokontakt primer. Hygroscopic walls are treated with primers that reduce moisture absorption, such as Tiefengrund, which are allowed to dry.
- Sheets of drywall are marked, cut, and holes are cut out for sockets and switches. The height of the sheets should be such that there is a gap of 10-12 mm at the bottom. During installation, gypsum board scraps are installed in these places, and the cracks are closed with Saniter-Silicone sealant or similar. The edges must not come into contact with wet surfaces, therefore, gypsum plaster boards are placed on pads and the time required for the glue to set and water vapor to evaporate is waited. Then the linings are removed and the cracks are sealed. To be on the safe side, it is good to secure the drywall on the wall with 5-6 self-tapping screws.
IN last decades together with the concept of “European-quality renovation” entered our lives a large number of new construction and finishing materials. One of them is plasterboard sheets. Despite its relative novelty, plasterboard for walls and ceilings has become not only very popular, but truly indispensable. The durability of a plasterboard wall depends on the right choice material and compliance with all technologies for installing gypsum fiber board sheets on the wall. In this regard, it is necessary to take a closer look at what thickness of drywall is best for walls and how to attach it correctly to load-bearing surfaces.
Advantages and disadvantages of gypsum board sheets
Gypsum plasterboard (GKL) and its variety - gypsum fiber (GVL) sheets today occupy a leading position among wall finishing materials. Their great popularity is explained by a number of positive qualities, which favorably distinguish gypsum sheets from other interior finishing options.
- High technology and ease of installation. Do-it-yourself gypsum fiber board wall finishing is accessible even to non-professionals who have never worked before finishing works. With its help, you can not only produce, but also bring to life the most daring interior design projects.
- Lightweight design. Due to the low mass of gypsum sheets, this design does not exert excessive pressure on the foundation and interfloor ceilings.
- Fire safety. Gypsum is a non-flammable material that can withstand open fire. In this regard, plasterboard finishing can be used to create fire-resistant partitions.
- Environmental friendliness of the material. Since gypsum board does not contain any impurities harmful to humans, it can be used in any residential premises, including bedrooms and children's rooms.
Among the disadvantages of this material are:
- Low strength. A wall covered with plaster cannot be used for hanging massive objects - bookshelves, wall cabinets, plasma panels, etc.
- Fear of dampness. Gypsum is highly hydrophobic and gets wet when exposed to moisture, losing its shape and rigidity. In this regard, sheets or gypsum boards cannot be used for exterior finishing work.
Due to the high hygroscopicity and poor resistance of gypsum to dampness, any gypsum board panels are intended exclusively for finishing interior spaces. This even applies to so-called moisture-resistant plasterboard sheets.
Types and technical characteristics
Modern industry produces several types of gypsum sheets. They all differ in their operational and technical characteristics. To choose the right drywall for a particular room, you should become more familiar with its properties.
Purpose
- Standard drywall, also known as basic. It consists of a sheet of pressed gypsum, covered with cardboard on both sides, and is designated by the abbreviation GKL. The most common type of plasterboard sheet, widely used for finishing rooms with normal level humidity.
- Moisture-resistant drywall (GKLV) is designed for use in rooms with high levels of humidity. The moisture-resistant sheet contains special water-repellent additives that reduce its hygroscopicity. In this regard, gypsum plasterboard sheets can be used for cladding bathrooms, toilets, and kitchens.
- Fire-resistant sheet - designation GKLO. Intended for finishing rooms with an increased risk of fire. Thanks to the treatment with fire retardants, such sheets are able to withstand the effects of open flames twice as long.
- Fire-moisture resistant plasterboard (GKLVO). It has a whole range of improved properties - it can be used in both wet and flammable areas. For example, it can be installed in kitchens with gas stoves.
Gypsum fiber sheet
Gypsum fiber sheets (GVL) are a special group of gypsum finishing material. GVL slabs made from a mixture of gypsum and cellulose fibers in a ratio of 5 to 1. The distinctive quality of gypsum fiber sheets, compared to gypsum plasterboard, is their increased strength. Thanks to this, fairly heavy suspended structures can be attached to the wall.
One self-tapping screw, screwed in, can withstand up to 30 kg of load.
GVL can be installed either on a pre-assembled frame or directly on a leveled load-bearing base. In the first case, using self-tapping screws, and in the second, using construction adhesive compositions. GVL adhesive can be either silicone sealant, or “liquid nails”, and to brick and concrete surfaces sheets can also be fixed using tile adhesive on a cement or polymer base.
Dimensions
To more fully answer the question of which drywall is best to use in a particular case, Special attention should be given to the size of the sheet. Standard dimensions of drywall are presented in the table.
To optimize material costs, it is advisable to select the size of the plasterboard sheet that is a multiple of the length and width of the surface to be sheathed. In this case, the amount of non-target waste will be minimized.
Sheet thickness
One of the most important indicators is the thickness of the plasterboard sheet - the scope of its application and installation technology depend on this. On modern market finishing materials presented widest choice gypsum sheets: their minimum thickness is 6 mm, maximum - up to 50 mm. First, most thin material, intended for covering surfaces with low external loads - for example, ceilings.
Also thin sheet Great for making various decorative elements interior design - arches, niches, curved structures. This is due to its low rigidity and ability to bend, taking the required form.
The most massive gypsum boards up to 5 cm thick are used to level floors as a basis for finishing floor coverings that require a perfectly flat surface: laminate, linoleum, parquet. The thickness of the plasterboard for the wall is selected depending on its functional purpose.
In rooms with an increased likelihood of mechanical impact on the walls (hallways, staircases, children's rooms), it is advisable to use thicker sheets. For decorative finishing In the interiors of living rooms or bedrooms, thinner varieties of drywall can be used.
The most popular thickness of gypsum plasterboard for walls is 12…15 mm, which allows for the most optimal use of the material. Such a sheet can withstand significant physical exercise, impacts and pressure, while it does not weigh down the wall structure and has a low cost.
To improve resistance wall plasterboard To external loads, different design solutions are also used when installing partitions. According to the provisions of SNiP, in construction they use the following types partitions made of gypsum plasterboard or gypsum fiber board.
S-111
This design consists of a single frame, sheathed in one layer on both sides with plasterboard sheets. The inside of the wall can be filled with insulation or soundproofing materials, most often - mineral wool or expanded polystyrene. The thickness of such a wall depends on the width of the frame profile and the thickness of the gypsum board sheets used. Weight 1 cu. m of wall S-111 is about 25 - 30 kg.
S-112
It is a wall made of single metal frame and two-layer sheathing on each side. This design has increased soundproofing properties, up to 50 decibels. In addition, it is often used to create fireproof screens to isolate potentially flammable rooms. In this case, the frame is filled with non-combustible material and sheathed with fire-resistant sheets. Weight of 1 cubic meter - from 50 to 55 kg.
S-113
This wall is intended for use in finishing rooms with high humidity. It has a single frame and is sheathed with a triple layer of moisture-resistant plasterboard. To improve thermal insulation and sound absorption, drywall can be used in combination with mineral wool filler. The mass of m 3 walls is about 75 kg.
S-115
To create the S-115 wall, a double frame is used, sheathed with two layers of gypsum board. This increases the strength of the partition, and, depending on the brand of plasterboard sheet used, increases fire or moisture resistance. As an option for wall C-115, each layer of the double frame can be separated from each other by an additional sheet of plasterboard. The mass of such a wall ranges from 55 to 70 kg/m3.
S-116
Such a wall is structurally similar to type C-115, but unlike it, it has spaces inside for laying communications - electrical wiring, pipelines, ventilation ducts. The thickness of the S-116 wall largely depends on the dimensions of the communication lines. The mass of a cubic meter of S-116 can be up to 60-65 kg, the noise absorption rate is up to 50 decibels, the resistance open fire in the gypsum board version - about 1.5 hours.
S-118
A wall with a higher class of resistance to mechanical stress, designed to prevent unauthorized entry into the room. It consists of a single frame, similar to walls S-111...S-113, sheathed with three layers of gypsum plasterboard. To enhance strength, a sheet of galvanized steel is inserted between each layer of drywall. At the same time, this increases the wall’s resistance to open flame and moisture.
The video below shows the installation procedure plasterboard partition with your own hands.
Having familiarized yourself with the main operational and technical characteristics of gypsum plasterboard sheets, you can imagine which drywall is best to use in a particular case. Also, based on the purpose of the room, you can choose the most suitable type of wall construction.
This material is often used to level base surfaces. This construction material has become in demand and popular due to its positive characteristics. And before deciding which drywall to use for the construction of partitions, you need to understand the types and sizes of the material that are presented on the construction market.

Types of gypsum boards
Manufacturers try to take into account all the wishes of customers, and therefore they currently produce several types of drywall: 
Watch the video review existing species drywall.
Interesting! IN Lately You can find material with a thickness of 25 mm, and it may also differ in the shape of the edge.
GKL partition – installation technology
A plasterboard partition can be installed without the help of professionals; it is enough to know some of the nuances. Typically 12mm material is used.
To assemble the structure you need to prepare:
Step by step steps installation of an interior partition The tools and material are ready, let's start installation.
Frame for partition
The profile for plasterboard partitions is selected depending on the purpose of the structure. If this is a simple partition that will not be subject to increased load, then a 50x50 mm profile is suitable.
Options for constructing a plasterboard partition frame 
There will be .
In this case, high-quality sound insulation is necessary, so you need to buy 75x100 mm profiles.
The guides must match the rack elements.
Drawing with dimensions of the partition frame Algorithm for performing the work:
- apply markings on the ceiling, floor and walls using a level and plumb line;
- fasten the guide profile along the line. Attach the element to the strip and screw it, do a similar action on all surfaces;
- cut the wall profile into sections according to the height of the room and insert it into the guide and secure it. Advice! If the plasterboard partition does not need reinforcement, then the profiles are mounted in increments of 60 cm;
- cut the crossbar from wall profile, which will be installed for, fix it with “seeds” to the height of the opening;
An example of a door opening design from a profile 
- cut elements 70 cm long - these will be jumpers;
- form ears on the jumpers to secure them to rack profile;
- lay or pipes.
Stages of installation of a plasterboard partition frame The sheathing is ready, let's proceed to the sheathing.
Installation of gypsum boards
Which drywall is best to use depends on the purpose of the structure. Some professional builders It is recommended to buy gypsum fiber board with a thickness of 9 mm and lay it in two layers. We'll consider step by step instructions single-layer wall cladding:
Important! If a two-layer partition sheathing is used, then the second layer of plasterboard coating starts from half so that the seams of the previous layer are covered with the whole slab.

Partition finishing
Before you start final finishing, on both sides, then perform the following actions:
Option finishing plasterboard partitions 
The installation of the plasterboard partition is completed. Which drywall is best to choose for a partition? It is impossible to answer this question unequivocally; it all depends on the purpose of the structure and the room in which the partition will be located.
Using such plasterboard panels, you can quickly level walls, redesign a room, or assemble the necessary structures (boxes, suspended ceilings).
However, they are produced Various types sheets having a wide variety of characteristics, and the main purpose. This should be taken into account when drawing up a project repair work, and most importantly, estimates.
Which drywall is best for walls to choose from a huge variety of materials?
The use of gypsum plasterboard in combination with a frame and a large number of attachment points makes it possible to create structures with a significant margin of safety.
The material itself consists of two parts: a filler, which is gypsum, and a cardboard shell.
The usually common size of plasterboard is: width 1200 mm, length 2500 mm, with a thickness of 12.5 mm. However, before choosing drywall for walls, it is worth understanding the standard sizes and purpose.
Companies produce panels with thicknesses: 6.5, 9.5, 12.5, 15, and up to 24 millimeters. The length of the sheets ranges from 2000 to 4000 mm, and the width can be 600, 900, 1200 mm.
However, when choosing a material, you need to understand why certain types of panels are needed, and how to distinguish them.
Classification of plasterboard by purpose
The premises intended for different conditions operation: kitchens, bathrooms, living rooms and basements. And everywhere the finishing is susceptible to various influences: humidity, temperature, mechanical stress and others. To solve these problems, companies produce plasterboard panels that can withstand certain types of influence.
GKL
The most common types of sheets, most often referred to as wall sheets. They are used for finishing living rooms, as well as assembling the walls between them.
The material is installed on the frame, or frameless way. This allows you to create durable wall finishing in the shortest possible time.
Marked gray on planes.
But, for use in a humid microclimate, a different type is needed - moisture resistant.
GKLV
Has green markings on the front side. The main purpose is to decorate walls and ceilings in rooms with high levels of water vapor in the air ( plasterboard sheet moisture resistant).
This a good option for finishing the walls of bathrooms or semi-basement rooms, the filler contains an antiseptic additive that prevents the formation of fungus and mold.
In other respects, the slab does not differ from its wall counterpart, except for the price. Such panels are somewhat more expensive.
GKLO
The plasterboard sheet is fire-resistant - it is able to withstand and maintain an integral structure even when exposed to an open flame (for a limited period of time!). The effect is achieved by adding fire retardants to the composition.
The main specialization of the panels is the assembly and finishing of specialized structures: boxes ventilation ducts, fireplace trims and others.
Marking by front side red or pink. Like other types of slabs, they are more expensive compared to wall analogues.
Other specialized types of plasterboard sheets are also produced.
- GKLVO is a moisture- and fire-resistant sheet that combines both properties.
- Acoustic plasterboard - provides sound insulation of rooms and proper acoustics.
- Arched - the purpose of creating curved configurations, a more plastic material.
- Laminated - has a PVC coating, not intended for living rooms.
What thickness of drywall is best for walls?
Everything is clear about the purpose of the material; the type is selected according to the basic conditions, but questions may arise with the thickness of the slab (you can choose from 6.5 to 24 mm). What options to choose for wall decoration?
Typically, in the cladding of residential premises, a sheet thickness of 12.5 mm is used; such panels are able to withstand basic loads, and when using appropriate fasteners, even the hanging of massive objects and household appliances.
Thicker plasterboard is used for structures that will be subject to overload: shelves, stands, niches, seats and others.
Thick slabs from 15 to 24 mm are used exclusively in structures subject to significant loads. However, their installation is possible only on a reinforced metal frame.
IN self-cladding walls with such material should not overpay for specialized types. They should be used only for their intended purpose, but there is no need to save money, do not buy cheaper panels with minimum thickness for basic finishing, otherwise in best case scenario will have to do restoration repairs.
