The invention is a horizontally operated door barrier which presents virtually an impenetrable doorway barrier while maintaining ease of personnel access through the portal. The invention consists of a movable vertical spool upon which is wrapped a material or screen for covering the doorway. The spool moves laterally across the doorway, rolling or unrolling the screen wrapped thereon, thereby uncovering or covering the doorway. The barrier can be used to prevent passage of insects, moisture, heat, dust and like environments.
