Remember that different hardwood flooring would have different acclimation periods. This is because hardwoods are extracted from a variety of environments and processed in different ways. Thus their adaptability capacity differs.
3 Factors Affecting Hardwood Flooring Acclimation Time
Now you have to remember that acclimation time varies for a few reasons. If you want to know why the duration of acclimation varies and how long a particular wood needs to acclimate, learning about these factors may help.
1. Wood Species
The very reason why hardwood flooring acclimation time varies is the wood species you are using. For instance, a tree growing in a tropical area would require more time to cope with the moisture content in a cold area. Similarly, it would take less time to acclimate when installed in a tropical climate.
2. Humidity Level In The Area
The humidity level in a particular area is the most crucial thing in determining the acclimation time of the hardwood flooring. This is why measuring the moisture content of the room is very necessary before installing hardwood flooring.
3. Lack Of Moisture Regulation
If you are living in a condition where the weather fluctuates, you have to have a temperature regulating system. What I mean is to adjust to the changing conditions, the indoor condition should be kept constant. For example, if your room doesn’t have a heating system in winter, the planks may need more time to acclimate .
