lumisuojia

Lumisuojia is a Finnish term that translates to "snow guards" or "snow retainers." These are devices installed on the roofs of buildings to prevent the sudden and dangerous shedding of snow and ice. When snow accumulates on a sloped roof, it can become a heavy mass. As temperatures fluctuate, this mass can slide off in large chunks, posing a significant risk to pedestrians, vehicles, and the building itself. Lumisuojia are designed to hold the snow in place, allowing it to melt more gradually or to break off in smaller, less hazardous pieces.

There are several types of lumisuojia. The most common are snow fences, which are typically made of metal bars or mesh and are installed in rows horizontally across the roof. These fences create a barrier that disrupts the smooth slide of snow. Another type is snow combs, which have a series of angled projections that catch and break up the sliding snow. Some systems incorporate a combination of different elements to enhance their effectiveness. The specific design and placement of lumisuojia depend on factors such as the roof pitch, the typical snow load in the region, and the building's architectural style. Their primary purpose is to enhance safety by mitigating the hazards associated with snow avalanches from rooftops.
