3. Application
Roller shutters have many applications, including doors
for vans, garages, kitchens, schools, prisons and warehouses.
In some parts of the world, roller shutters are subsidized by local
governments due to the inherent security benefits.
In areas that are frequently exposed to inclement weather, roller
shutters are used as a method of insulation and can protect
windows against hail damage.
