In recent years, with the gradual improvement of people's quality of life, floor heating wooden flooring has been favored by consumers at home and abroad. But what kind of wooden floor is more suitable for floor heating? This is the concern of our floor manufacturers and consumers. In recent years, there have been a lot of comments from various media, and we suggest that everyone discuss it together.

First, briefly introduce what we have learned about the use of underfloor heating in the world. Our company has been exporting solid wood composite flooring for more than ten years, and our products are exported to more than 20 countries.

1. Exported to Europe, Britain, France, Italy and other countries with higher quality of life, their hardcover room floor chooses the solid wood composite floor with three layers as the main and multi-layer as the supplement. Among them, the proportion of floor heating floor is about 70%, the total thickness of the floor is 10~14~15mm, and the thickness of the surface layer is 3~4mm.

2. Because Japan and South Korea exported to Asia are relatively cold in winter, more than 90% of them use floor heating multilayer solid wood composite flooring. The total thickness selected is 9~10~12mm, and the surface layer is generally 2~3~4mm.

3. The United States and Canada, which are exported to North America, mainly use multi-layer solid wood composite flooring with three layers as a supplement. The thickness is 12~15mm, and the surface layer is 2~3~4mm.

On the whole, the general trend of floor heating in developed countries in the world is solid wood composite as the main body, and pure solid wood flooring or laminated wood flooring is rarely used.

According to the characteristics of floor heating solid wood composite flooring popular in developed countries in the world, we have analyzed and summarized the following points for everyone to discuss:

1. Good stability: Wood expansion and contraction caused by environmental dryness and humidity changes are its natural attributes, but after drying treatment, the product made by longitudinal and transverse gluing, its performance is relatively stable, and it is not easy Expansion, contraction and not easy to deform. Therefore, it has been loved by developed countries such as Europe, the United States, and Japan.

2. Save high-quality resources: We are a large country with a population of 1.3 billion. The high-quality wood resources that can be used for flooring have long been cut down and are on the verge of exhaustion. In the past ten years, more than 99% of high-quality tree species have relied on foreign imports, so it is urgent to save resources. Many countries in the world have adopted various measures to protect high-quality tree species. The surface layer of the solid wood composite floor is selected from medium and high-grade tree species such as oak, walnut, teak, etc., and 0.6~2mm thin veneer is commonly used in China. For those with high quality requirements at home and abroad, the thickness of the surface layer will be 3~4mm, and its design and use can be up to 100 years. as long as. The base materials are eucalyptus, pine, Italian poplar and other tree species, which grow fast and are cheap. In general, by improving the comprehensive utilization rate of wood (for example, cutting an 18mm thick pure solid wood floor slab into 3mm slices can increase the utilization rate by four times), and more use of fast-growing wood to achieve the purpose of saving resources.

3. Comfort: The surface layer is made of high-quality tree species, and the wood has high density and strength, which is beneficial to resistance to abrasion, compression, impact and collision. The substrate is made of medium and low-density wood. Such a wood configuration not only does not affect the strength of the wood floor, but on the contrary it will bring a more comfortable foot feel.

4. The floor heating floor should not be too thick: wood has heat insulation and resistance to electrical resistance is also its natural property. Therefore, the thickness of 9~15mm is generally adopted for underfloor heating in the world. If the thickness is 18mm, it will seriously affect the heat conductivity and increase the cost of electricity and gas. Northeast and North China adopt central heating and charge on a quarterly basis, which does not have much impact on consumers. In Eastern China and other regions, each household uses gas and electricity for heating independently, which will not only cause waste of electricity and gas, but consumers will also spend more money, but will also seriously waste wood resources.

5. How to further reduce energy consumption and provide rapid heating

Our company has applied for two patents (with photos) for heating grooves and heating holes for underfloor heating to reduce energy consumption. For the underfloor heating floor for customers in Italy, South Korea, etc., a heating groove is opened on the back of the 10mm thick floor, and for the floor of 14~15mm, a heating hole is opened on the back to achieve a rapid heating effect. The following is the experiment done in the floor heating experience room of our company: room 6*8=48㎡, choose teak floor heating solid wood composite floor, its specification is 910*125*10/4mm, the back of the floor is 30mm spaced, 3mm wide, 5mm deep. Warm tank, use Korean electric heating film to conduct warmth. At 8 am, the indoor temperature is 6°, and the floor heating thermostat is set to 20°. After 25 minutes, the floor surface temperature reaches 16°. After 45 minutes, the floor surface temperature rises to 26°, and the room temperature has reached 18° Around, it feels warm like spring.

6. Choose environmentally friendly adhesives

1. The amount of formaldehyde released by environmental protection standards in Europe, the United States, Japan, and China

European standard E1 (≤1.5mg/L), E2 outdoor (≤5.0mg/L) (E2 is only used outdoors)
Japanese standard F☆(≤5.0mg/L), F☆☆(≤1.5mg/L), F☆☆☆(≤0.5mg/L), F☆☆☆☆(≤0.3mg/L)
American standard E1≤9mg/100g, E0 (≤0.5mg/L)
Chinese standards E1 (≤1.5mg/L), E0 (≤0.5mg/L) (E0 is only used for laminate flooring, E2 is only used outdoors)
2. The use of high-quality adhesives is the key to making solid wood composite flooring, which not only requires good bonding strength, but also ensures that the environmental protection meets the standards. Such as imported Tyre glue and Casco, Japan's national starch glue, the price of these glues is about three-quarters higher than the domestic price, but the glue viscosity and formaldehyde emission are guaranteed. For more than ten years, our company has never complained about environmental protection failures. If the domestic adhesive manufacturer has a certain scale and holds a responsible attitude to customers, it should be no problem for the adhesive to reach E1 and E0 grades, and meet the national standards to meet consumer requirements.

3. In the floor heating solid wood composite floor, the three-layer solid wood structure is only rolled with two-layer glue, which should be the one with the least amount of glue, so it has always been the most favored by European consumers.

7. Suggestions for the use of floor heating temperature control

1. The temperature of the floor heating room is controlled at 18-20°. Because it is cold outside in winter, the temperature inside and outside should not be too different, otherwise it will easily cause discomfort such as colds.

2. When using floor heating floor for the first time or changing seasons, the temperature should be 2° per hour, and the temperature should be within 10° on the same day, and it can be set to within 23° after three days. If the temperature rises too fast, it will cause the floor to shrink quickly, crack, twist, tile or deform.

3. After the interior decoration is completed, it is recommended that the customer should open the two sides of all windows by about 3cm to allow air circulation and prevent rain. All the doors of the house are opened. After three to six months, all kinds of unhealthy gases such as indoor paint and paint are basically eliminated, and you can move to a new house.

(The above are the suggestions and opinions of our company, I hope everyone will participate in the discussion)
