White Duo Smart Louvre Vent with Fly Mesh, 135mm x 135mm

This white Duo Smart louvre vent with integrated fly mesh measures 135 mm × 135 mm (5.31″ × 5.31″), combining backdraft prevention and insect protection in a compact, low-profile grille. Its built-in damper automatically seals shut to block reverse airflow, while the fine mesh screen keeps out flies, dust and debris without impeding ventilation.

Constructed from UV-stabilised plastic with a clean white finish, this vent resists weathering, corrosion and impact for years of reliable performance. The screw-fix frame allows for quick installation into new or existing openings, and the crisp white tone blends seamlessly with any interior or exterior décor.
