Geothermal heating is more and more popular, but geothermal heating has many requirements on the floor. The "ground radiant floor heating standard" has already been issued. The standard has relevant provisions for the relevant floor heating source, floor covering and product selection. The use of geothermal heating to buy the floor must be "prescribed for the remedy," materials, thickness, cushion and other aspects have certain requirements.

â—†Bamboo floor and pure solid wood flooring are heat-resistant and easily deformed
Geothermal floors are laminate flooring and solid wood multi-layer flooring. For bamboo geothermal flooring and pure solid wood flooring can not be "competent" this "work". From the perspective of the amount of deformation, the deformation of ordinary bamboo flooring is smaller than that of solid wood flooring, but it is much larger than that of reinforced composite flooring and solid wood multilayer flooring. Therefore, in geothermal environment, the use of ordinary bamboo flooring has certain risks.
If pure solid wood flooring is used in geothermal environment, the floor should be installed as much as possible, to prevent the seal coating at the floor lock from being damaged during the repeated installation of the floor, and to cause the floor to deform due to changes in the air humidity. In addition, it is necessary to check whether the surface of the ground is smooth and smooth before installation. If any convex sand particles are to be disposed of, prevent the moisture-proof coating of the moisture-proof film and the floor from being damaged due to sand particles.
â—†The best thermal conductivity is 12mm~15mm thickness
In general, the smaller the thickness of the floor, the greater the heat flow. The greater the thickness of the floor, there is indeed a certain influence on the conduction of heat, but "the impact is not great." But the thickness is best to choose the thickness of 12mm to 15mm, compared to 12mm floor heat conduction faster than 15mm, but in a continuous heating environment, the difference between the two heat conduction is not obvious; floor thick foot feel better, The cost is high. For areas with continuous heating, if the heating system can guarantee the basic requirements of room temperature, you can choose a slightly thicker floor. In addition, under geothermal conditions, the floor withstands relatively high temperatures. As the temperature rises, the release rate of formaldehyde on the floor accelerates, so floors with low formaldehyde emission should be selected as much as possible.
As a geothermal floor, it is best not to choose a floor that is too wide or too long. The larger the floor size, the greater the gap in the geothermal environment. In particular, a three-layer solid wood composite floor with a wide surface, if the moisture content of its surface layer should be controlled below 8%, otherwise there will be floor cracking. Cracking can also occur under geothermal conditions. Therefore, when producing three-layer solid wood flooring for geothermal heating, the moisture content of the surface layer must be strictly controlled.
Under geothermal conditions, when the moisture content of the local slab changes, the amount of slat expansion is different, and rib-like ripples appear on the floor surface of the floor. If the thickness of the three-layer parquet flooring surface is more than 3mm, this phenomenon is not easy to appear. Therefore, three-layered solid wood flooring with a thickness of 3 mm or less is not suitable as a geothermal floor, and 7- to 11-layer solid wood flooring is more suitable for geothermal heating.
â—† moisture pad is better to use tin foil
The moisture-proof pad is made of tin foil and has good heat conduction. If the floor mat is too thick, it will cause the floor to move up and down, causing the locks to rub against each other, making it easy to produce noise, and it will also hinder the volatilization of thermal energy. In addition, it is also possible to select a 2 mm plastic floor mat, which can act as a buffer and dampen moisture.
