Hörmann´s Flex strip curtains are especially suitable for use as inexpensive doors for large warehouse openings. The durable UPVC strips seal to a large extent and only open up to the width of the vehicle or load. This reduces temperature loss to a minimum, even with heavy through traffic, thus saving energy. The first-class transparency of the Flex strip curtains improves lighting conditions and reduces lighting costs. Suitable for use in production of foods or medication and in cold store areas.
