Chipboard grooved moisture resistant: pros and cons

The name of the moisture-resistant tongue-and-groove chipboard was given to the plates, the characteristics of which are improved with the help of moisture-resistant polymeric materials and a four-sided tongue-and-groove system (tongue-groove). Thanks to these features, the material, which can be recognized by the green blotches on the surface, has the following advantages:

easy recovery;
resistance to decay, fungus and mold;

Mold on boards that will never be on moisture resistant tongue and groove boards

low thermal conductivity, which provides savings on room insulation;
environmental friendliness, which ensures the use of chipboard in schools, kindergartens, hospitals and other premises and buildings with high hygiene requirements;
long service life;
moisture resistance, the value of which is the highest for materials of the P5 class, which retain their geometric dimensions and structure even after a long stay in water.

Differences between ordinary and moisture resistant chipboard

Painted and laminated boards can be used as a topcoat. And among the few disadvantages of laying grooved chipboard, it is worth noting the need for additional protection of its ends from moisture and a small content of formaldehyde resins, which are used for pressing chips... Also, this material weighs more than similar-sized wood panels and is not suitable for installation on curved structures.

Application of chipboard with tongue and groove

The scope of application of the material is residential and office buildings, office premises, sports facilities, warehouses and shopping centers. At the same time, tongue-and-groove chipboard is suitable for the following structures:

ceilings. To do this, it is worth using plates of a minimum, 12 mm thickness, which are easy to connect and easily replace drywall... They are also used to level the ceiling surface before applying topcoats;
foundations. The slabs themselves are not included in the construction of the bases, however, removable formwork is made from them;
walls and partitions. Plates increase heat-shielding properties and level the surface before painting, wallpapering or installing panels;

Laying materials on walls

floor coverings. Dry prefabricated screed, "floating floors" and raised floors are made of grooved chipboard for the floor. With its help, coverings of sports grounds, tennis courts and podiums are also strengthened.

Floor scheme on logs using chipboard

Another way to use the material is to perform roofing work. Due to the increased density and ease of installation of the slabs, they are the best option for roof insulation. A relatively small mass allows you to reduce the load on the rafter structures and save on their manufacture.

Moisture-resistant tongue-and-groove chipboard: dimensions, price, brands

With standard thicknesses from 12 to 22 mm (and non-standard ones used by some manufacturers of 10 and 38 mm), tongue-and-groove plates have two main standard sizes:

600 x 2440 mm;
600 x 1830 mm.

Due to its small dimensions, the weight of one slab is small and reaches only 5 kg for a 16 mm thickness. Ceiling elements weigh even less - up to 4 kg. This feature increases the ease of installation of structures.

On the domestic market, you can find products from different manufacturers. The assortment of each company differs in both the cost and the thickness of the sheets - only the length and width of the sheets are the same. If you are going to buy chipboard for furniture, the price per sheet is indicated in the table below. The most common slabs of the following brands:

Brand	Material	Minimum price, rub.
QuickDeck	Chipboard 12 mm	270
QuickDeck	Laminated chipboard 16 mm	324
"StroyExpert"	Chipboard 12 mm	335
"Sphere"	Chipboard 12 mm	340
"PlitTorg-S"	Laminated chipboard 12 mm	580

The most popular brand, which can be found in almost every building supplies store, is QuickDeck. The material retains its characteristics for at least 6 years when used for floor coverings in rooms with high traffic of people. And the walls finished with it do not require major repairs for at least 20 years.

QuickDeck Products

Important! Chipboard of the domestic brand QuickDeck is distinguished by the best ratio of cost to quality and fully complies with European standards. However, the products of several other brands are represented by a large assortment.

Material reviews

The reviews left about the tongue-and-groove chipboard are mostly positive. The only drawbacks that consumers notice are the small assortment of standard sizes and the relatively high cost of the material. Reviews of chipboard can be presented in the form of the following table:

Consumer	Feedback	Benefits	disadvantages
Alexey, St. Petersburg	Used standard 16mm wall and floor tiles. I got an excellent floor with a pitch of 300 mm between the lags. However, the painted walls made of grooved chipboard disappointed - the paint cracked at the seams and the walls had to be additionally putty.	Ideal for floors.	Not suitable for paintable walls.
Sergey, Voronezh	He made clean floors from this material, covered with one layer of varnish. There are no problems with the floor, it looks great, it washes well, it fits quickly - 30 sq. m laid in one working day.	Good laying speed, affordable price. The material is not as echoing when walking as laminate flooring.	When used, I did not find it.
Nikolay, Khimki	Used the material about a year ago for the construction of the floor. Used daily. Doesn't creak like some brands of inexpensive laminates. When laying, it was conveniently cut, but when water got from the shoe, the seam swelled a little.	Simple assembly and processing. Quite good moisture resistance.	The seams require additional processing, since water falling on them can damage the chipboard.
Maxim, Nizhny Novgorod	This is the second time I have been using tongue-and-groove chipboard. I get a solid and even floor. After accidental water ingress, nothing happens to the surface. Even the leaking ceiling and the puddle that formed on the floor did not swell the material. And, thanks to the tongue and groove, a minimum of time is spent on installation.	The presence of a tongue. Satisfactory moisture resistance.	It did not work to dock with sheets of the same size (600x2440x16) from another manufacturer, left over from the last repair.
Alexey, Moscow	Easy to lay on the floor on logs with a distance of 400 mm. I got a very flat surface on which I laid linoleum. However, water falling onto the untreated floor caused a loss of smoothness.	Fast installation of a quality subfloor.	High price. Inability to use to get a good finish floor.
Oksana, Saratov	With the help of grooved slabs of different thicknesses, the builders made in my apartment the floors, the walls, and the ceiling. It turned out to be a good replacement for both drywall and flooring	Convenient, practical, affordable	Small assortment. When buying, we faced the lack of the required thickness in some stores.
Andrey, Moscow	Good stuff, I recommend it to everyone. He sheathed them a hallway in the country and a relaxation room in a bathhouse.	Convenient dimensions - easy to transport even on your own car. Perfect joint compatibility, easy installation.	The same small size, which is a plus for transportation, can be called a minus for finishing.
Mikhail, Arkhangelsk	I made the floors in a private house alone. I was pleased with the result - the floors do not creak, do not deteriorate from moisture.	Convenient size for single mounting - easy to carry and install.	The joints of the sheets are not perfectly flat in the plane.

Features of the choice of tongue-and-groove moisture-resistant chipboard for the floor

When choosing slabs that play the role of a rough floor covering, pay attention to their moisture resistance:

the PA brand has the maximum resistance to moisture, however, the price of moisture-resistant chipboard per sheet is much higher;
the PB slab is less moisture resistant, which is why it is less often used in rooms with high humidity.

Important! Choosing between the relatively expensive first grade and the more profitable second one, you should pay attention to the absence of unpolished areas and chips. Such slabs are used for finishing floors and have a high surface quality. The second grade can only be used to obtain a finishing surface.

Another factor is taking into account the concentration of formaldehyde. Class E1 has no more than 10 mg of substances per 100 g of particle board, E2 - up to 30 mg, E3 - up to 60 mg. The lower the indicator, the more environmentally friendly, and, therefore, safe to operate the plates.

Installation recommendations

Due to the dimensions of the tongue-and-groove chipboard, the installation of the subfloor using it is easily performed alone without the involvement of third-party helpers. Although, to obtain a satisfactory result, a strict sequence of work must be followed. The installation steps can be summarized in the following table:

Installation phase	Picture	Description
Installation of a lag before laying chipboard		Work begins with laying logs (wooden beams of a suitable section), the distance between which is chosen according to the thickness of the plates. For a 16 mm chipboard, 300–400 mm are sufficient. For 22 mm, take 500-600 mm.
Filling the space between the logs with insulating material		When laying sheets, a distance from their edge to the wall of about 20 mm is left. The space under the beams is covered with sand, and between them - with insulating materials.
Checking floors with a level		The horizontalness of the plane is checked by the building level.
Fastening plates to the base		Sheets are stacked from the wall opposite the entrance. The first is fixed to the logs with self-tapping screws, the distance between which is chosen from 200 mm at the edges and 300 mm in the middle. The hats are sunk into the floor by a couple of millimeters.
Installation of grooved slabs one into another		The edges of the edges of the plates are sealed (with mastic or PVA glue). Each next is inserted into the groove of the previous one, trying to keep the seams on the logs.

The installation process for floating floors is different from conventional work. At the same time, the moisture-resistant chipboard for floors replaces the dry screed. A "floating" structure is called because there is no rigid connection between the coating and the concrete base. It consists of several layers of material, the last of which is chipboard. And the laying process itself looks like this:

Installation phase	Picture	Description
Vapor barrier for "floating floors"		First, a vapor barrier is laid on top of the concrete base, which can be used as an ordinary polyethylene film.
Sound insulation backfill for "floating floor"		Expanded clay or expanded polystyrene sheets are laid in the second layer.
Chipboard substrate device		Another layer is a substrate made of a membrane, plastic, and other materials.
Tongue-groove installation method used for grooved slabs.		The work is completed by the installation of grooved chipboard.

With the same materials for ceilings, partitions and walls, work gets done even faster. Due to the fact that the installation of sheets on vertical structures does not require the manufacture of lathing, installation becomes easier, and the cost of repairs is reduced. For fastening to the wall, use standard self-tapping screws, the distance between which should be within 300-400 millimeters. The thickness of the ceiling slabs should be no more than 12 mm, and for their fastening, not a crate, but a rack frame is installed.
