räystäisiin

Räystäisiin refers to the eaves of a building in Finnish. The eaves are the lower edges of a roof that extend beyond the exterior walls of a building. They serve several important functions, primarily related to weather protection and structural integrity.

One of the main purposes of eaves is to protect the building's walls from rain and snow. By extending outwards, they direct water away from the foundation and siding, preventing moisture damage, rot, and erosion. This also helps to keep the building drier and more comfortable, especially in climates with significant rainfall or snowfall.

In addition to water management, eaves can also provide shade during the summer months, reducing the amount of direct sunlight that enters the building. This can contribute to lower cooling costs by keeping the interior cooler. In winter, their design can allow sunlight to penetrate and warm the building, depending on the angle of the sun.

Structurally, eaves can help to support the roofline and provide an area for attaching gutters and downspouts, which further manage water runoff. They can also contribute to the aesthetic appearance of a building, with their design and materials varying greatly depending on architectural style and regional influences. The term "räystäisiin" encompasses these functional and often decorative elements of a building's roof.
