Wood is hygroscopic, i.e., it readily absorbs moisture from the air and condenses it into water. So be sure at all times to maintain relative humidity between 45% and 50%, which is also ideal for human health, and temperatures between 18o and 24oC (65 and 75oF). Major variations could cause irreparable damage to your hardwood floors.
In addition to the above recommendations, we suggest you follow the instructions below:
Humidity levels play a key role in the upkeep of hardwood floors. If the level is too high, the wood expands and swells. If the level is too low, the wood contracts and shrinks. Therefore, it is important that you control the relative humidity level in the ambient environment.
Hardwood floors may expand and shrink depending on the seasons and heating cycles. Even when installed according to our instructions, floors may shift slightly at different times of year, causing small gaps to appear. Some gaps may self-correct with seasonal humidity or temperature variations or if ambient conditions are maintained as described above, others may not. These gaps are not covered in the warranty.
Heating with electricity or wood can decrease ambient humidity levels. We recommend using a humidifier during heating season when the air is dry to keep the wood from contracting. On the other hand, if the air is humid or very humid, a dehumidifier and air conditioner can help prevent the wood from expanding. Another way to lower humidity levels is to turn the heat on for short periods of time.
