Why does SPC core flooring factory need to calculate shrinkage joint size?
Jul 27, 2021

In recent years, SPC core flooring factories rely on environmental protection, formaldehyde-free and waterproof flooring, which has become popular at home and abroad, especially in some developed countries such as Europe and the United States. In recent years, the domestic market has gradually become hot. According to the increasing consumption concept of domestic users, it can even be said that the popular market has been finalized, and the rest is only a matter of time.

Although the installation method of the SPC latch floor is the same as that of the wood floor, the grasp of details in the installation process is different from that of the wood floor. According to the existing market research, different brands of SPC floor in the individual site pavement, there will be edge warping, arch, expansion joint, and even snap fracture phenomenon. Through the analysis and investigation of the SPC core flooring factory, the following conclusions are drawn

1. The raw materials of the SPC floor are thermally compounded by PVC and calcium carbonate with advanced technology. The production process is different from that of wooden floors, so the thermal expansion and cold shrinkage are also different. The existing paving masters are basically done by wood floor masters, and the "general paving method" is adopted. The shrinkage joint size is not calculated according to the thermal expansion and cold shrinkage parameters provided by the SPC core flooring factory. If the room is slightly large, but the reserved gap is too small, especially when the temperature difference between winter and summer is too large, it is very easy to have no space to expand and cause arching and warping phenomena.

2. In order to reduce the cost, an SPC floor with poor quality and low price is adopted, which has poor stability and a high rate of thermal expansion and cold shrinkage. And the loss caused by the "general paving method".

3. The problem of accessories selection is also to reduce the cost. Choosing a thinner skirting line or narrow specification, right angle, and layering virtually limits the space of the contraction joint and brings unnecessary loss.

There's no object in the world that doesn't expand with heat and contract with cold, so does the floor. No matter the shrinkage ratio of large or small SPC floor, as long as according to the floor shrinkage performance adopted bySPC core flooring factory, site environment, room size, winter and summer temperature, to calculate the shrinkage joint size, even the floor with poor stability can also minimize the problem rate and reduce unnecessary losses.
