With Fall and Winter coming sooner than we think, it is time to start thinking about changing humidity and wide plank floors. Today we take an excerpt from Northern Wide Plank’s helpful article which can be found HERE

CHANGING HUMIDITY AND WIDE PLANK FLOORS

Being a living product that is crafted and finished to enhance its natural beauty, a NWP specialty wood floor is best suited to a consistent relative humidity in order for ultimate performance and lasting beauty. What is meant by a natural living product is that, even once crafted and finished, these wood floors have the abilities to still take on and emit moisture resulting in expansion and contraction of the plank. This is why it so important that the environment these floors are installed in, are controlled and monitored for a healthy relative humidity.

As we shift into fall, and then winter, the cooling weather itself leads to lower humidity, and this shift is enhanced further as indoor heating, in-floor radiant heating etc takes more moisture from the air. In contrast, the summer sees increased humidity both outdoors and indoors.

Wide plank floors especially, by nature, will always expand and contract as the seasons change. In controlled conditions, this is barely noticeable, but under extreme conditions or excessive shifts in moisture it can cause unsightly—and even unsafe—damage that requires expert repair.

WINTER AND WIDE PLANK FLOORS

NWP wood floors are aptly dried to suit the changes in season we see, especially in the Northeastern regions of North America, but when these floors are exposed to extreme dry conditions for extended time, they can dry out causing the top layer to shrink beyond what the engineered substrate allows. This can cause a number of issues including unwanted cracks and splitting along the grain of the hardwood top layer, cupping and crowning of planks, especially on ultra wide planks and gapping* between planks.

*small gaps between planks are normal to see during the winter months, especially with in-floor radiant heating, but excessive gapping and large gaps should not take place in a properly controlled environment.

PROTECTING YOUR NWP WOOD FLOOR

Here are some important steps to take that will protect your NWP wood floors from changing humidity we experience in the 4 seasons and also help to create a more healthy and comfortable indoor living environment.

  • Proper floor installation methods and procedures that allow natural expansion and contraction of wood floors
  • Maintain a relative humidity of 30-55% in your home. Evening having a hygrometer in the main areas of your home helps to easily monitor the relative humidity
  • Install proper humidification/dehumidification systems for the climate you live in
  • High quality windows and proper insulation values play a large role in maintaining relative humidity levels
  • When turning on in-floor radiant heating, do so gradually so the wood floor can safely adjust – please refer to our radiant heat guide for this

More information on installation methods and installing over radiant heat can be found in our installation guides.

Caring for your wood floors by maintaining relative humidity will also protect art pieces, wood furniture and cabinetry and pianos.
