It is made of long, thin boards. These boards often overlap one another. This helps the building stay dry. In the United States, people call it clapboard. In the United Kingdom, Australia, and New Zealand, people call it weatherboard.

Some people also call it bevel siding or lap siding. It can be used on walls or even roofs. This material helps protect a house from the weather.

There are different ways to make these boards.

Long ago, people split wood by hand. This process is called riven. It made boards with a thin edge and a thick edge. This shape is called a feather edge. Later, mills used saws to cut the wood. One way is to use a radial saw. The log turns 360 degrees while being cut. This creates a taper and a vertical grain. Another way is flat-sawn. This method cuts across the growth rings. Flat-sawn wood can cup or bend more easily.

History tells us where these names come from.

An old meaning of clapboard refers to small pieces of oak. These pieces came from Germany to make barrels. The name is a partial translation from Middle Dutch. In Australia, people use a special type called chamferboard. This uses tongue-and-groove joints to link the boards. This makes the outside of the wall look flatter. In New Zealand, weatherboard was very popular before 1960. After big earthquakes in 1855 and 1931, wooden buildings were seen as safer.

Many different kinds of wood are used for siding.

In North America, people used oak, pine, or spruce. Modern clapboards often use red cedar or pine. Some people leave the wood raw. It turns grey as the tannins wash out. Others use paint or stains to protect it. Traditional colors were black or white. Today, there are many more colors because of chemical pigments. You can find clapboard on cottages, windmills, and shops.

Today, you might see different materials that look like wood.

Some siding is made of vinyl or aluminum. Other types use fiber cement. These are lightweight alternatives to real wood. You can see these styles in many places. Some houses are Dutch Colonial Revival styles. Others are Victorian terrace houses in Australia. Whether it is old or new, this siding helps shape how our towns look.
