Grey Duo Smart Louvre Vent with Fly Mesh, 140mm x 210mm

This grey Duo Smart louvre vent with integrated fly mesh measures 140 mm × 210 mm (5.51″ × 8.27″), offering backdraft prevention and insect protection in a contemporary, low-profile grille. The built-in damper automatically seals shut to block unwanted airflow, while the fine mesh screen keeps out flies, dust and debris without impeding ventilation.

Constructed from UV-stabilised plastic with a sleek grey finish, this vent resists weathering, corrosion and impact for years of dependable performance. The screw-fix frame enables quick installation into new or existing openings, and the neutral tone blends seamlessly with both modern and traditional décor.
