Why Does Wood Warp?

Proper Storage
Good storage plays a significant role in protecting wood from warping and maintain its functionality. A good practice is to store wood ina dry, well-ventilated area. Limit exposure to direct sunlinght and ensure you boards are lying flat and slightly off the ground to prevent water damage. Additionally, place weights on wood boards to keep them straight, and put stickers-1-by-1-inch between the boards to allow for better ventilation.
Adequate Drying
Ensuring adequate during is one of the kye ways to prevent wood from uneven drying. Instead of relying on natural drying, some manufacturers use the kiln drying method to control the during conditions. Manufacturers can control factors like humidity and temperature over a even time in a kiln oven, ensuring even drying.
Space Acclimation
Even after drying, wood may still be affected by the humidity of its installation environment. A good warping prevention technique is to acclimate wood to the climate of the area where you will use it. Depending on the project, you can place wood within its final resting atmosphere for several days to get accustomed to the humidity level within the space.
What Type of Wood Is Best to Prevent Warping?
Choose durable wood to avoid malformations. The most durable wood:
-
Is stable under changing humidity, such as fir or pine.
-
Is dense, such as cedar.
-
Has a straight grain pattern, such as redwood.
The most stable doors are solid all the way through without a core and veneer. However, solid wood doors are usually more expensive and still do not guarantee you will entirely avoid warping.
We recommend a few other options:
-
Plastic laminate doors: Commercial plastic laminate doors have a composite core and are covered in durable plastic instead of a veneer, so there is no reason to worry about why wood warps with these door designs. Plus, you can still achieve a wood look through customization.
-
Metal doors: Installing high-quality metal doors have many benefits. They can help protect an interior from fires and break-ins, and their hollow core allows for great insulation and soundproofing. Metal doors are the most secure, durable and cost-effective option for many applications.
