The curtain is mounted on external walls, doors or windows. It protects rooms in houses, hospitals, hotels or offices from penetration by insects, while permitting ventilation. It is a gauze curtain with a bar-type roller and with draw-cord and housing case, horizontal sealing batten, and two side guide-rails, each with a sliding groove on the narrow side facing the curtain. The curtain can move in rails in front of the window or door frame, in front of, or inside, the soffits with the rails in the same plane as the case opening slot.
