It acts as a first line of defense against the elements. This includes the sun, rain, snow, heat, and cold. By blocking these things, siding helps keep the inside of a home stable and comfortable. The material used also changes how a building looks.

While masonry walls do not need it, any wall can be sided. Walls made of wood or steel beams must always have siding.

Most siding is made of small pieces rather than one huge sheet. This is done so the material can expand and contract. This movement happens because of changes in moisture and temperature. One common way to join pieces is called clapboard, or lap siding.

In this style, planks are laid horizontally starting from the bottom. Each board overlaps the one below it to keep water out. Another style is board and batten. This uses thin strips of wood to cover the joints between panels.

People have used many different materials for siding throughout history. Wood is a very versatile choice that can be painted any color. In colonial North America, many people used Eastern white pine.

Shingle siding was used in early New England buildings. This style became popular again during the late 19th century. Other materials include stone, slate, and even stucco. Stucco is a plaster-like material applied over a lattice. However, stucco can crack because it does not have joints to allow for movement.

Modern builders also use plastic and metal for many different reasons. Vinyl siding is a type of plastic that comes in many colors. It is often made in units twice as high as wood clapboards.

Metal siding is often seen on industrial or modern buildings. Aluminum is great for coastal areas because it forms a hard coating when it hits air. Steel is a good choice for places with severe storms. This is because steel is very resistant to dents from hail.

Newer technology has created insulated siding to help save energy. This siding has expanded polystyrene foam, or EPS, fused to the back. This foam fills the gap between the house and the siding. It can reduce energy use by up to 20 percent. These products are often Energy Star qualified by the U.S. Department of Energy. Manufacturers say this type of siding can last more than 50 years. It is also breathable, which helps prevent rot and mold.
