The effects of UV light on wood cabinetry.

Although it’s not something you might think about, did you know that ultra violet (UV) light rays found in natural sunlight could affect the appearance of your wood cabinets over time?  Here at Merillat, we’ve already thought of it!  In addition to finishes that enhance strength and durability, smoothness, and general protection, Merillat applies UV inhibitors to all wood cabinetry as part of our finishing process. The finish on your cabinets will not change, but the wood may, depending on its natural characteristics. Factors that impact UV exposure include the amount and direction of light exposure and the portion of the cabinet that receives light.

We’ve tested our wood species and finishes so that you’ll be able to determine the approximate effect that UV rays may have on the cabinetry in your home. The tests we use follow the American Society of Testing Materials (ASTM) standards for quartz ultra violet light (QUV). The actual results in your home will vary depending on these three factors:

1. Exposure to light (for example, direct from the south, east or west, or indirect from the north).
2. The portion of the cabinet that receives the light (top, base, etc.).
3. The wood itself. While the finish does not change in color, the wood itself will.

Examples of UV Exposure

Below are examples of wood cabinets in several finishes and the effects of sunlight on the unfinished and finished products. These images demonstrate the tested effect of 24, 175 and 400 hours of UV exposure equal to that experienced at noon. The differences are quite noticeable!

To ensure that you are pleased with the long term look of your cabinetry, be sure to discuss the unique characteristics of each wood species and the natural daylight exposure of your room with your kitchen design specialist before making your selection. UV exposure on Cherry wood species will yield the quickest changes.  While it is difficult to protect cabinets from the effects of UV, please keep in mind that this is the natural aging of wood and it also affects other furniture, flooring, and wall coverings.
