Humidity Monitoring for Wood Floors

We all know that water can be damaging to your wood floors, but did you know that humidity can be just as harmful? With proper maintenance from relative humidity (RH), your hardwood floors will look ageless for years to come while others will begin to warp, twist and crack. RH is the amount of water vapor present in the air compared to what the air can hold at that temperature. With wood being a hygroscopic material, it exchanges moisture with its surrounding environment. If you own wood floors, then moisture is your worst enemy.

Problems Facing Wood Flooring

Wood reacts to the environment it is in. With the changes in the seasons and fluctuations in temperatures wood gains or loses moisture due to the air’s temperature and RH. Air is everywhere filling every crack and tiny space, and infiltrating your hardwood floors. While only a small amount of moisture will get into your wood boards, over time the effects can be detrimental.

The RH condition at the floor level is what’s important for monitoring flooring. Wood flooring is affected by the air directly next to it, not feet or inches above it. We are most familiar with the environment above the floor, which is typically controlled to make us comfortable when indoors. It is also recommended to monitor the RH immediately under the floor if you have a basement or crawl space.

Adapting to Seasonal Changes 

Those warm and humid months can raise your indoor humidity up to 90%. With high RH levels, your wood flooring will absorb moisture and expand. As a result, this will cause your wood flooring to expand, which causes cupping. Cupping is when the edges of the boards are higher than its center. Cupping will cause the neighboring boards to press against each other, which can lead to cracked boards. Avoid your floor from cupping by maintaining an indoor RH level of 40-60%. Never allow the indoor RH level to go over 65%.

Heating our homes during the colder months causes the air to dry. The wood flooring then loses some of its moisture and contracts. When removing moisture from the air, thin gaps can appear between the boards, which is normal. Most of the gaps will close up in the spring when humidity levels rise again. Try to avoid these deficiencies from occurring by maintaining RH levels from 40-60%. No gaps will transpire if the indoor RH levels don’t go lower than 40%.

The IoT Solution

Humidity control is necessary regardless of where the wood flooring is installed. Floor damage is becoming more common for home and business owners. Some of these problems may affect the resale value of your property, or become expensive to repair. For a long time, the available solutions were too expensive, inconvenient, or inaccurate to use, which lead many people to become complacent, considering these damages as unavoidable. That is no longer a problem thanks to the Internet of Things!

The Internet of Things (IoT):  the network of physical objects (“things”) embedded with sensors, software, electronics, and network connectivity, which enables them to collect and exchange data.

How to Protect Wood Flooring

With Monnit’s affordable remote monitoring system in place, you will be able to monitor the humidity levels in your home and maintain the significant value to your property. Monnit’s wireless sensors allow you to place the sensor anywhere to get the most accurate reading, and with their small size, no one will notice them. Whether you’re a homeowner, property manager or business owner, you can monitor your humidity levels from anywhere, at any time via computer, smartphone or tablet and receive alerts via text, voice and email the moment there is an issue.

Remote monitoring systems are still relatively new, so most homeowners don’t know about them, or just haven’t implemented them yet (primarily because they haven’t found a cost-effective solution that meets their needs). Maintain your property with Monnit Solutions!
