A sunshade is a device or material used to block or filter sunlight, protecting both interior spaces and individuals from the harmful effects of excessive sun exposure. Sunshades can come in various forms, including physical structures (like awnings or pergolas), fabric-based solutions (such as blinds or shades), or integrated systems in vehicles and buildings (such as solar control glass). These shades help reduce glare, lower indoor temperatures, and protect furniture, flooring, and occupants from UV radiation.
