First, common types and characteristics of SPC floor thickness

The thickness of SPC floor is generally 3.2mm, 4.0mm, 5.0mm, 6.0mm and so on. Thinner floors usually have the following characteristics:
1. The price is relatively cheap, which can reduce the cost of decoration.
2. It is more suitable for some Spaces with strict restrictions on the height of the ground, and will not occupy too much of the height.

Thicker floors may have the following advantages:
1. Foot feeling may be slightly better, giving people a more comfortable walking experience.
2. To a certain extent, it may be more durable and relatively strong impact resistance.

Second, the thicker the better

1. Cost factor
- Increased thickness leads to increased costs, including purchase costs as well as transportation and installation costs. If the budget is limited, too thick floor may bring greater economic pressure to the renovation.
2. Stability considerations
The stability of SPC flooring mainly depends on its substrate and production process, rather than the pure thickness. Excessively thick floors may be more prone to deformation problems in different environments, especially in areas with large changes in humidity.
3. Ground requirements
- Thicker floors may require a smoother ground base. If the ground flatness is not enough, the thick floor may appear empty drum, warping and other problems after installation, affecting the use effect and life.
4. Installation difficulty
- Thick floors are relatively heavy, which increases the difficulty of construction when installed and may require more manpower and time. And for some complex installation environments, such as small Spaces or places with more obstacles, the installation of thick floors may be limited.

3. Suggestions for choosing the right thickness

1. Select based on the application scenario
- If it is a family bedroom, living room and other areas with higher daily use frequency, you can consider a slightly thicker floor, such as 4.0mm or 5.0mm, for better foot feeling and durability.
- For commercial places, such as offices, stores, etc., need to consider the flow of people and the intensity of use, you can choose a medium thickness of the floor, such as 3.2mm or 4.0mm, both to meet the needs of use, but also to control costs.
- For some temporary sites or projects with higher cost requirements, a thinner 3.2mm floor may be a more suitable choice.
2. Consider ground conditions
- If the ground flatness is good, you can choose a slightly thicker floor to obtain a better use effect. If the ground is not very smooth, it is recommended to perform ground treatment first, and then choose the appropriate thickness of the floor according to the actual situation.
3. Refer to brand and quality
- Different brands of SPC flooring may vary in quality and performance. When choosing the floor thickness, you can refer to the brand's reputation and product quality, and choose products with reliable quality and stable performance.

To sum up, SPC floor is not the thicker the better, need to consider the actual situation according to the use of scenarios, ground conditions, costs and other factors, choose the appropriate thickness of the floor.
