If you decide to purchase plywood, then first you need to familiarize yourself with its varieties. This material is a canvas based on wood. Sheets are made by gluing peeled veneer. In one product, the number of layers can vary from 3 to 23. As a rule, the described material is manufactured using a technology that involves the arrangement of wood in adjacent sheets mutually perpendicular. However, on sale you can find options in which the veneer is located in one direction. The thickness of the outer layers is 3.5 millimeters, while the inner layers are 4 millimeters. The technique may involve the use of varnishes and resins of various properties, this gives the final product certain characteristics.

General Description

Depending on what kind of mechanical surface treatment was used, some types of plywood can be distinguished. Thus, on sale you can find polished, unpolished material or one that is subjected to similar processing on one or two sides. These canvases can be made from different breeds.wood, among them poplar, birch, needles or aspen can be distinguished. You can also find a combined material, which has several varieties of wood material. Birch plywood is considered very durable. This is due to the significant physical and chemical properties of wood, which is supported by the multi-layered structure. As for the coniferous variety of canvases, they are made of pine, which provides high strength with little weight. Such types of plywood are successfully used in the construction of houses. The grade of material is determined by the number of knots per square meter. Thus, four varieties of the described material can be purchased on the building materials market.

FK grade plywood

Considering the types of plywood, you will probably pay attention to this variety, which belongs to moisture-resistant materials. In the production process, carbamide resin is used to glue veneer sheets. These sheets are intended for indoor use. The material is not capable of cracking through, and is also quite easy to process. This applies not only to sawing, but also to drilling. For work, you can use a saw or an electric jigsaw. The canvases are quite easy to attach to each other, and if necessary, they can be strengthened to any surface using self-tapping screws. This material is called universal, since it can be used both for private construction work and in the manufacture of furniture. Considering the types of plywood,you, first of all, pay attention to FC, in its production spruce or birch veneer is most often used. When comparing material from birch and softwood, it can be noted that the canvases will differ in density, the first option has this indicator within 650 kilograms per cubic meter, while spruce and pine show a density equivalent to 500 kilograms per cubic meter.

The types of moisture-resistant plywood described above are used in the decoration of walls and ceilings. When carrying out these works, canvases are used, in which one of the sides has the highest grade. You can also find this material as a rough base for laying laminate and parquet, while sheets are used, the thickness of which varies from 5 to 15 millimeters. To do this, you can purchase low grades, since the sheets will be sawn, which indicates the possibility of getting rid of defective elements. Using canvases in tandem with a substrate, you can improve the heat and sound insulation qualities. If you will purchase plywood, types, the use of this material, you can consider in the article. It should be noted that FK plywood is used in the production of drawers, shelves, back walls of cabinets, as well as some components of armchairs and sofas. This material has also found its use in the preparation of stands, as well as signboards, however, these elements can only be used indoors.

FKM grade material

Considering the main types of plywood, you should pay attention to the brand mentioned. It has improved water resistance qualities and is manufactured using a technology that involves the use of melamine resins. This variety is unique, as environmentally friendly materials are used for the manufacture. Due to these characteristics, the material gained the opportunity to be used in furniture production. Among other things, FKM is used for interior finishing work.

The above material is made using melamine, which is a colorless crystalline substance. It is almost insoluble in water. Such resins, unlike phenol-formaldehyde resins, practically do not decompose when exposed to room temperature, therefore they are widely used in the production of various household products. Among the distinguishing features of this material is increased moisture resistance, which is sometimes compared with that possessed by PSF.

FSF brand plywood

This material is made by gluing veneer sheets together using phenolic resin. This type of plywood has increased water resistance. It is not recommended to use it when carrying out interior decoration, due to the fact that phenolic resins are harmful to human he alth. As a rule, these canvases are used when carrying out outdoor finishing work.

Manufactured using pine, beech or birch veneer. Among the qualitative characteristics, one can single out high wear resistance, as well as resistance to mechanical stress. Most often this material is used in concrete and roofing works, in car building and in the automotive industry.

Pros and cons

Considering the types of plywood for the floor, you should not choose the FSF brand, but it is great for the needs of industry and, if necessary, external work. This material is characterized by flexural and tensile strength. At the same time, these characteristics remain almost unchanged with changes in humidity and temperature. Cloths are quite easy to process and drill, they hold screws and nails well. In addition to toxicity, these sheets are flammable. When exposed to flame, the material will support combustion, while fumes will be released into the environment, which are quite dangerous to human he alth.

Features of laminated plywood

Laminated plywood, the types of which differ in grades and base materials, contains PSF. This layer is covered on both sides with a special film. This type of material is used when it is necessary to make formwork. The material can be used repeatedly, which is its great advantage. These sheets are distinguished by the qualities of moisture resistance due to the presence of a film as the upper layers. Adhesive is used in the production processwhich is highly water resistant. The technology involves the use of pine, birch, larch or poplar. Among other things, on sale you can find combined options. This material is most common in the automotive industry, aviation, when carrying out railway work, in shipbuilding, furniture production, as well as in the trade and advertising field. In private construction, such laminated sheets can be used to fill a monolithic foundation. The material is relevant when arranging the floor, roof, walls, as well as when sheathing the external and internal surfaces of buildings.

Advantages of laminated plywood

Cloths are distinguished not only by moisture resistance, but also by high strength. They can be used in the most difficult conditions, such as elevated temperatures, humidity, as well as constant mechanical stress. The surface of the material can be affected by aggressive chemical substances that are not able to change the qualitative characteristics of the material. Additional advantages include long life, affordable cost and ease of installation. Among other things, the material is quite easy to process, it is wear-resistant and environmentally friendly. Consumers choose laminated plywood also because of its attractive appearance. When buying, you can choose the color of the film and density. Manufacturers offer options for sale, the surface of which can be smooth or embossed.

Sheet thickness

Types of plywood and thickness described in this article,help you make a choice. For example, the last parameter can vary from 3 to 30 millimeters. In this case, the layering varies from 3 to 21 units. So a material that is 27mm thick will have 19 layers, while 9mm plywood will have 7 layers.

The maximum deviation can vary from 0.4 to 1.2 millimeters. This indicator grows in direct proportion to the thickness of the sheet. You should not overpay if there is no need to use plywood of impressive thickness, such expenses will be inappropriate. That is why it is recommended to familiarize yourself with the assortment presented in the store before purchasing.
