Additional Technical Information: General
Just as too dry an environment can cause damage to wood floors, an environment that introduces too much moisture into the wood can also cause damage.
- Subfloors, whether they are cement or gypsum based products or other wood products, must have moisture contents that are within National Wood Flooring Association guidelines. Moisture barriers must be used when moisture content exceeds guidelines.
- Too much moisture can cause planks to swell and then change shape as they are restricted in their movement.
- Humidity systems must have the ability to control humidity within a specified comfort zone for the wood. That is generally considered to be between 30% and 50% relative humidity.
- Systems such as “swamp coolers”, which do not have humidity controls must be monitored to prevent too much moisture being introduced into the environment.
- If high volume humidifiers, such as “swamp coolers” are used, a polyurethane finish would be suggested to delay as much as possible the effect of the humidity on the floor.
- Owners who heat wood floors with no thermostat control, do not have adequate humidity in their homes, or are not using the required cleaning solutions may have damage to wood flooring products. Such damage is at the owner's sole cost and risk and is not covered by warranty.
