Natural Variations in Wood

Part of the inherent beauty of wood is the natural variations that occur being that it is an organic material. Grain, pinholes and knots, are all characteristics that tell the story of the tree that becomes your window or door. But these variations are not to be considered defects. Some of the natural characteristics of wood that you can expect to see with your new Weather Shield Windows & Doors are:

Color Variation

The varying attributes of wood lend themselves to color variation. The application of stains or clear finishes can enhance these variations. End grains can absorb more stain and appear darker.

Grain & Character Marks

Character marks such as pinholes, knots and resin canals along with the natural grain of the wood all add to the warmth and richness of the product. These character variations are not considered defects.

Aging

The color of wood evolves, typically darkening over time, and is not a defect. Certain species such as cherry, will continue to mellow and darken over time. The application of stains and/or clear finish does not prevent this natural process. Color change may be more noticeable in woods treated with a clear coat or light-colored stain.
 

Environmental Factors

  • As wood ages, the appearance of the finish may change or darken over time due to environmental factors such as interior lighting, sunlight and humidity.
  • Finishes react to prolonged exposure to tobacco smoke, resulting in discoloration, which is especially noticeable on lighter finishes.

Joint Lines

Wood is in a constant state of expansion and contraction. This normal movement may cause some hairline cracks at the joints in the finish surface. This is a natural occurrence and does not weaken or diminish the strength of the joints. Factory finishes are primarily applied prior to assembly and are not intended to cover the joints.
