Preparing for Autumn/Winter: The Effects of Cold Weather on Wood
Wood absorbs moisture and warmth from the air. It swells with heat and moisture in the summer and heavy rainy simply worsens the effects. Wooden garden furniture especially is prone to contract and expand as the temperature changes. As the summer ends and autumn arrives; it is all the more important to protect your wooden furniture from the cold.

The daily cycle of expansion during warmer afternoons, and contractions during cold nights can ruin your furniture for good by affecting its lustre, shine, shape and sonorous qualities. Outdoor furniture, such as a wooden garden bench, is especially prone to damage and needs strong protection measures.
How to Protect Outdoor Wooden Furniture From the Elements
Wood preserver is a chemical solution that protects wood from woodworm, dry and wet rot, and halts the daily cycle of expansion-contraction with temperature variations.
Wood preserver is applied to furniture either at the time of manufacture, or later on, and is vital to prolonging the life of wooden garden furniture in particular.
Wood preserver is mainly available in three varieties, depending on the primary chemical used:
- Organic solvent preservatives
- Copper chromium arsenic
- Alkaline copper quaternary
These chemicals fill the microscopic gaps present in wooden furniture, and suitably expand and contract with temperature changes. Organic solvents are preferable to the other two varieties because they are non-toxic and can be more efficient at preserving wood.
You can also buy natural wooden preservatives from most hardware stores these days. Unlike the above mentioned chemical preservatives, these natural preservatives, such as linseed and tung oil, are completely non-toxic.
