As a rule, in the construction market, finishing materials are offered for purchase as a package - complete with related materials and necessary equipment for repairs. Among them is a substrate for parquet - a coating that can not be avoided when arranging the floor.
What are the functions of the underlying material?
Agree that manipulation is done for a reason. Moreover, the substrate for the parquet board is supposed not only to the parquet, but also to a number of other similar coatings. The gasket must compensate, strengthen and perform a number of additional functions, namely:
- Improving thermal insulation performance.
- Improving the heat level of the floor.
- Providing excellent sound insulation.
- Simplification of installation of a parquet board or a laminate.
- Isolation from moisture penetrating from the base.
- Slight leveling of the surface.
Each of the above functions is significant, and the choice of the right type of material helps to improve the quality of the installed flooring and its lifespan.
What are the substrates for the laminate
What construction and repair materials you will not find in the market! A wide range of products are presented regardless of industry, especially in the market for linings. The most common such variations of laying for parquet:
- polyethylene foam;
- foil;
- cork;
- bitumen-cork;
- composite.
Polyethylene foam substrates
In the rating for sales of related materials for parquet, it beats all ratings. This is the best substrate for a parquet board. Most often selected by the client and most actively sold. It copes with its task perfectly, which means it greatly facilitates the work and eliminates the possible problems associated with laying the floor:
- easily and quickly laid on the floor;
- maximally absorbs vibration from walking, compensating for them;
- helps to increase the level of heat;
- creates a reliable insulating layer that protects against moisture.
Thanks to a special impregnation and a dense film layer, the material is not damaged by small pests: rodents and insects, and bacteria and fungi on the surface of the polyethylene foam die immediately.
The material is inexpensive, and laying does not require special preparation, it is enough just to roll the roll and cut the canvas to the required length.
Among the disadvantages of such a lining, a short lifetime is allocated - up to 10 years, after which it completely breaks up.
Foil pad
This type of coating is a modification of any other flooring taken. In this embodiment, take one of the above types and paste one of its sides with foil, which contributes to an additional increase in all its properties by 3 times. The most common version of foil foamed polyethylene.
Laying the covering film is an important point. It is important to ensure that the foil is on top. This will allow the sheets to be glued with a tape made of stanyol.
Do not know which substrate for parquet board to choose? Uniquely foiled. Such a substrate is suitable for the installation of any type of floor on which it is supposed to install a parquet board or laminate, but best of all it shows its functions on wooden surfaces with a holistic and rigid structure.
Cork bedding
This is the best material for laying under the parquet. Compared with polyethylene foam, it will last at least 40 years. Of the positive qualities, the function is distinguished:
- excellent heat preservation;
- quick warming up of a parquet;
- isolating noise from steps.
Cork underlay for parquet board is different:
- elasticity;
- quick adaptation to operational conditions;
- moisture resistant;
- natural composition, which, in turn, makes them completely safe and hypoallergenic;
- high strength, which allows the use of cork substrate on a variety of surfaces.
Cork - the best material for installation under the laminate, according to experts.
Cinder layer
It is better known under another name - a park lag. This is a high-quality and widely used coating, used in conjunction with many floor coverings, and characterized by:
- high rates of heat and sound insulation;
- vibration absorption property;
- high strength
- moisture resistant.
The only but significant drawback of the coating is the bitumen resin in the composition. When the permissible temperature is exceeded, this substance begins to release substances with an unpleasant tarry odor - formaldehydes, which are unsafe for human health and life. For most residential type premises, the use of such a substrate option for a parquet board or laminate is strictly prohibited.
Along with the disadvantage - a significant advantage due to the lack of the need for waterproofing in the process of laying parquet.
Composite materials
Such a substrate consists of several components that form three layers and continuously interact with each other. As the base, foamed polyester is used, which easily transmits moisture, but perfectly muffles noise and transforms under the base, especially if there are surface irregularities.
In the middle layer, forming a flat surface, special balls. There is a constant circulation of air, contributing to the easy neutralization of penetrating moisture.
Duplex - the perfect base for a parquet board
Duplex is another type of substrate with a three-dimensional structure. The lower layer is made in the form of a porous film that transmits moisture in a small amount, filled with foam crumb, forming a dense layer that constantly maintains its shape. Between the second and third layers is the ventilation space. The last layer looks like a protective coating of plastic film. The thickness of the substrate under the parquet board is 2-3 centimeters.
Using a Tuplex backing will prove to be effective when the floor is laid on a wet screed or there is condensation due to temperature spikes in the room.
Moisture, falling into the structure of the lower layer, rises upward with air currents and evaporates efficiently, and excess steam goes out through the gaps formed between the parquet board and the wall in the baseboard.
This is the best option for the substrate, preventing damage to the floor covering from moisture. The coating is expensive, but in comparison with the parameters, price and quality are no worse than the cork lining option for the laminate.
The only negative is the delivery features. It is possible to purchase a substrate for a tuplex parquet only in the form of large rolls that are supplied to the market, and this is not always convenient and practical.
What and how to choose
Having become acquainted with the main options for lining for parquet, it can be argued that each of them is characterized by its advantages and disadvantages. The choice of a certain type of material depends not only on the substrate, but also on the purpose of the repair. To choose the best option, focus on the following criteria:
- thickness
- ability to level the base;
- type of delivery (plates or rolls);
- cost.
Lining Thickness
The maximum quality and appropriate substrate material should not be thinner than 1 centimeter. Some of the species reach a thickness of up to 3 centimeters. Foil lining does not exceed a thickness of 0.5 cm, cork can reach 3 centimeters, and coniferous substrate under the parquet board - at least 5 centimeters.
Surface Alignment Property
Remember that laying the substrate on an old base, you should choose the option that compensates for bumps and adjusts as much as possible, leveling the surface. So you will save on materials for bulk floors, and if you counted on a screed from the very beginning and planned this stage, then this criterion can be overlooked.
Plates or rolls
Quality does not suffer in any way from the form of delivery of the goods, but it significantly affects the speed of installation of a parquet board or laminate. The plastic form makes it possible to tightly fit the interlayer to the base and the coating that is laid on it. Before laying the parquet, spread the cork backing on the floor and leave it for at least 24 hours so that the coating is leveled.
Minimum and maximum price
Considering the cost of materials, they form an idea of the minimum cost, which averages 45 rubles per 1 running meter, and the maximum price - from 350 rubles per running meter of the substrate.
A substrate for a parquet board is an insulating material that creates a barrier between the parquet board and the base, it is thanks to it that the coating does not come into contact with the concrete surface.
The main functions of the layer include thermal insulation and sound insulation. Please note that the correct choice of material depends on the performance of the floor covering.
Now you know what a substrate for a parquet board is. Which is better, choose for yourself, based on the advantages and disadvantages of the options for flooring described above.
