Safe ventilation of cellar space with simultaneous screening against rain and insects: this is the perfect task for the RESi lightwell cover from Neher. Just like its colleague, LiSA, it is suitable for covering practically all lightwells made of plastic or concrete without gaps. The Neher RESi is available in two versions: diagonally mounted on the wall for maximum air intake and flat on the existing grating in a design which can be walked over.
