Valance top cover is the recommended and preferred covering material for all party tents. Our valance covers are heavy-duty tarps with an extra flap on all four sides to go over the edges of a canopy frame. The valance cover provides a little extra coverage and allows you to create a full enclosure when used with sidewalls and front and back walls. Each tarp features grommets every 18 inches and pull ties at all four corners, which tighten the cover for a more secure fit. Valance tarps are waterproof, rot-proof, and UV resistant.
