Humidity and temperature are two environmental factors that have a huge impact on the performance and stability of an assembled indoor basketball wooden floor, and understanding their effects is essential for proper assembly and long-term use. Wood is a natural hygroscopic material, which means it will absorb moisture from the air when the humidity is high, causing it to expand, and release moisture when the humidity is low, causing it to shrink. If the assembly process does not take these natural properties of wood into full consideration, changes in humidity and temperature will cause all kinds of problems, such as gaps between planks, warping, or buckling of the floor surface.
During the assembly process, it is crucial to make sure that the moisture content of the wooden planks is balanced with the normal average humidity of the indoor space where the court is located. This is why the acclimation step is so important: by storing the planks in the venue for a period of time before assembly, the wood can adjust its own moisture content to match the local environment. For example, if the venue is located in a region with very humid summers, the planks should be acclimated to a slightly higher moisture content before assembly, so that when the summer humidity arrives, the planks will not absorb too much extra moisture and expand excessively. If the venue is in a dry and cold region, the planks should be adjusted to a lower moisture content, preventing them from shrinking too much in the dry winter and creating large gaps between each other.
The expansion gaps reserved during assembly are designed specifically to accommodate the expansion and contraction of the wood caused by humidity and temperature changes. The width of these gaps must be calculated according to the total area of the floor and the local climate conditions. In regions with very large seasonal humidity changes, wider expansion gaps need to be reserved, to give the planks enough space to expand without pushing against each other. After the basketball wooden floor is fully assembled, it is also recommended to keep the indoor temperature and humidity as stable as possible throughout the year, using air conditioning or humidification/dehumidification systems when necessary. This will minimize the movement of the wood, keeping the floor surface smooth and stable for a very long time.
