Engineered hardwood flooring has become the popular choice for most homeowners and companies, since it offers many advantages. Firstly, it is available in a wide variety of textures, colors, and sizes to suit almost any type of décor. Interior designers prefer this flooring as it gives them almost unlimited flexibility in providing the required ambience and looks.

Another major advantage of engineered hardwood flooring is its resistance to moisture damage, and it being suitable for areas with light moisture such as kitchens, basements, and bathrooms. However, quality of engineered flooring will differ between manufacturers, and if you were looking for all the advantages of this type of flooring then it would be best to open the door towards quality products such as those available at sequoia-ltd.com.


Even with the best quality engineered hardwood floors, there are certain important points you need to consider during installation. If you want to avoid complications, pay attention to the RH (Relative Humidity) levels of your concrete sub-floor and the engineered floor product. Even though engineered flooring can be installed in areas, which is unsuitable for solid wood, you need to be cautious of extreme conditions. The breakdown of engineered floors is possible when you have not considered excess moisture, swings in humidity levels, and the absence of climate control.

Importance of Ambient RH Range

The area where engineered flooring has to be installed must be conditioned according to the guidelines provided by the manufacturer. One of the most important aspects is the ambient RH range specified by the manufacturer, and this will vary according to the quality of the product. For instance, certain flooring might need 30 to 50% RH while others may provide a wider range of 40 to 60%.

Therefore, while installing engineered hardwood floors, it is important to have control over the climate so that you do not go below or above the specified ambient RH range. For instance, if you are living in Nevada where the RH is around 30%, and lower range specified is 40%, you will have to bring the RH to 40% during installation and later, with climate control. You also need to be aware of the weather, as RH can fluctuate widely between summer and winter.

If you do not have climate control and do not keep to the RH range mentioned by the manufacturer, you might face issues such as end-gapping, de-lamination, and face splitting. In such instances, the warranty will be voided since you have not followed the manufacturer’s specifications.

You also need to be alert to changes in RH levels between floors and even between rooms. An increase in humidity can occur in places where there are steam radiators, humidifiers, stoves, showers, or any appliance that generates moisture.

Important Tips

Firstly, choose a quality product that provides a wide ambient RH range, If your area still does not fall into this range then you will need humidifiers or de-humidifiers to maintain the ambient range. Better still would be to have a humidification system for the whole house, which controls the RH automatically.

When the RH of the place is lower than the specified range, then are increased chances of ending up with a cupped floor. The wear layer that is on the top will dry faster than the internal core layers, and it will start to separate from the core material. This will result in lifted or curled corners. Your floor could also end up with splits or smaller openings and ruptures.
