What plywood is needed for the floor under the laminate

When choosing plywood for a laminate, it is necessary to consider not only the size and thickness of the sheets, but also the material from which it is made. After reviewing all the necessary characteristics, you can choose sheets suitable for decoration.

The choice of plywood for the laminate

It is necessary to choose the highest quality plywood. The most important options when choosing sheets are as follows:

1. Size and thickness of sheets.
2. Strength.
3. The number of layers.
4. Type of processing.

Therefore, when choosing, it is important to pay attention not to the appearance, but to the quality of the product.

Thickness

To choose the right thickness, you need to determine on which base the boards will be mounted, and in which way we will do it. There are several bases on which the choice of thickness will depend:

1. Concrete screed. About 1.5 cm. Sheets are folded in one layer.
2. Plank floor. At least 1.8 cm. You can also do with one layer.
3. Lags. It is recommended to make two layers with a total thickness of 3.5 cm. You can make both layers the same, but the best solution is to make the lower layer (about 2 cm) and the upper one (about 1.5 cm). When choosing a thickness, check the seams between the lags. The larger they are, the thicker the laminate will be needed.

Thickness is determined by the number of layers of wood from which it is made. The average thickness of each layer is from 1 to 1.5 cm. This indicator also depends on the manufacturer (they make a different number of layers and a different material size).

Note! If the plywood sheet is very thick, this does not mean that it will be tough and strong. When choosing the most important thing to pay attention to the number of layers. A thin tile with several layers can be stronger than a thick one-layer tile.

Sheet size

Regarding size, plywood is formatted and more formatted. The first type has a maximum size of 1525x1525 cm, the second - 3000x1500 cm. Each species has its pros and cons. For example, in smaller plywood there will be more joints, which will make the material less rigid. But at the same time, it’s more convenient to work with him. When choosing the size, it is necessary to take into account the features of the room itself, since the selected material provides for the presence of a minimum number of amendments.

What material to choose

To create plywood use pine, spruce and birch. For the inner layers use cheaper and affordable wood. It is very simple to distinguish the material, the coniferous wood has rich colors and patterns, and the birch is light.

Strength and resistance to deformation are higher for birch material (approximately 10%). Therefore, birch is more suitable for rooms where floor loads are always large. But the density and weight are greater than that of conifers. This will make installation more difficult. The price of birch is higher.

Needles are more practical. She has the following advantages:

1. The price is lower than a birch.
2. Less weight.
3. Protection against fungus, rot and mold, as wood contains oils.

Reference! This material is more suitable for rooms with a small floor load, and rooms with a high percentage of humidity (for example, a bathroom).

When choosing plywood for a laminate, the thickness of the sheets is also taken into account, but also the material from which the sheets are made. These options will help you choose the product that suits your room.
