Protecting Wood from Seasonal Temperature Changes

Temperature may be the main factor affecting wood, but it is far from the only one.

Wood expands when it's warm and contracts when it's cold. Naturally, these changes can cause cracks or warping. However, there are ways to protect cherished wood from weather.

Please keep reading to learn more.

Moisture and temperature

Temperature may be the main factor affecting wood, but it is far from the only one. Temperature changes create moisture. When it's hot and humid, wood absorbs the moisture and expands. In cold and dry weather, it contracts. This constant cycle exerts significant stress on the wood.

Keep conditions stable

The best way to protect wood is to create a stable environment. Use a humidifier in winter to stop the air from getting too dry.

On the flip side, a dehumidifier in summer makes the air less humid, so hot air won't be as effective in harming the wood. It's even better if the environment around the wood is reasonably air-conditioned.

Wise wood selection

Some woods handle temperature changes better than others. For example, teak and cedar are sturdy in different weather conditions. If starting a new project that involves wood, pick a variety naturally resistant to temperature changes, especially in climates with vast differences in seasons and weather extremes.

Finish the wood properly

The finish shields the wood by locking moisture out and keeping the wood's moisture stable despite changes in the air. Many finishes are available, such as oils, waxes, varnishes, and polyurethanes. Each has pros and cons, and different types work better on different types of wood.

Repair and care

Even the best-protected wood needs a little care now and then. Check it periodically for damage like cracks or warping. Catching them early means that a simple repair may be all that's needed.

Don't forget to reapply finish when necessary for ongoing care of the wood.

Store when not in use

Some wooden objects, like lawn ornaments, must be stored away during winter. When in storage, please keep the item off the ground and cover it up. This way, it will be more resilient to moisture and temperature extremes. A shed or garage is great, but even a breathable cover can help if no indoor space is available.

Embrace the change: design for movement

Finally, design something from wood with movement in mind if you're making something from wood. Allow for expansion and contraction in your joinery. This doesn't just prevent damage; it can also make the wood's natural movements a feature.

Protect the wood!

Seasonal temperature changes can be harsh on wood. Therefore, home elements, like cabinets, must be designed with expansion and contraction in mind. Talk to an expert carpenter or cabinet installer for more info about how to best protect wood in any season.
