This fabric dust-door separates the work zone from clean rooms so daily life can continue during renovation. The nonwoven polypropylene sheet helps limit airborne dust from sanding, cutting and drilling, reducing transfer into adjacent rooms and shortening post-job cleaning. A full-height, two-way C-path zip runs on the right-hand side and operates from either face, giving a generous opening for buckets, vacuums and tool cases without removing the barrier. A clear viewing window allows quick visual checks from the clean side, improving safety and reducing unnecessary entries into the work area. At 110 x 220 cm, the curtain fits most standard UK doorways in homes and offices. When a smaller aperture is required, trim the material to size and seal the cut edge with tape for a neat finish. Installation is straightforward: apply adhesive tape to a clean, dry frame, position the sheet, press firmly around the perimeter, then test the zip path for smooth travel. When the work is complete, peel away and dispose of the tape. The curtain rolls compactly for storage and reuse, subject to condition. Use it to separate living rooms, halls or kitchens while you paint, sand plaster, chase cables or drill fixings. For best results, keep the zip closed when not passing through, minimise draughts, and maintain ventilation within the work zone in line with safety practice. This is a dust-control aid rather than a sealed containment system. Performance depends on correct installation and local conditions. Tape is not included unless stated on the pack.
