The roof is made of easy-care, completely water- and windproof, UV-resistant 500D PU-coated polyester fabric. All fabrics are also fire-resistant (fire classification B1 DIN 4102-1). The roof is attached to the frame with sturdy corner adhesive loops and all sides are reinforced with quick locks to withstand even heavy wear. It is possible to conveniently attach the walls to the ceiling with Velcro, and the corners can be tightly closed with zippers. The corners of the roof have durable metal rings for fastening. There is a very comprehensive range of colors for ceilings, e.g. very popular striped fabrics!
