I make two variants of roller shutters: with visible and hidden boxes. You can choose plastic or aluminum lamellas. Besides manual handling, motorized variants are available as well, optionally with smart home system. Roller shutter have role in air conditioning, can be used as a security device, and are main parts of the facades of buildings. They can be equipped with insect screen.
How much does it cost? E.g. a 90x150 cm size costs 17,280 HUF (54 EUR) +VAT/pc (aluminum).
