Securit White Plastic Louvre Vent 9 x 6 Inch - Fixed Flyscreen

This Securit white plastic louvre vent is a 9 x 6 inch (approximately 229 x 150mm) ventilation cover designed to fit into an airbrick opening, plaster vent frame, or door to provide background ventilation for suspended timber floors, sub floor voids, utility rooms, and outbuildings. The angled slats let air pass freely in both directions while shedding wind driven rain and stopping larger debris and leaves from entering the wall or floor void.

Made from durable white plastic, this louvre vent will not rust, rot, or corrode, making it a popular low cost option for domestic ventilation compared to metal or terracotta covers. It is fitted with a fixed flyscreen that is riveted permanently into the vent body. This keeps flies and other larger insects out while still allowing you to wipe the mesh clean from the front when needed, though the screen itself cannot be removed or replaced. This louvre vent cover is not suitable for venting gas appliances or flues, it is intended purely for background wall and floor ventilation.

How to Use / How to Fit

If you are simply replacing an old or damaged airbrick cover, unscrew or unclip the existing louvre vent from the airbrick or terracotta frame and fit this vent in its place using the same fixing holes, no cutting or drilling of brickwork is usually required for a straight swap.

If you are fitting this louvre vent into a brand new opening in a solid wall, first mark out and chase or drill away the mortar to create an opening of the correct size, then bed the vent into fresh mortar, tap it flush with the surrounding brick face, and point around the edges to match the existing brickwork once the mortar has gone off. Always keep the slats angled downward and outward so that driving rain is shed away from the opening rather than channelled inside.

Frequently Asked Questions

What is a louvre vent used for?
A louvre vent is a ventilation cover with angled slats fitted into a wall, door, or airbrick opening. It allows a steady flow of background air into a room or sub floor void, which helps prevent condensation, damp, and musty smells while keeping out larger debris.

Do louvre vents leak in heavy rain?
A properly fitted louvre vent should not let rain in under normal weather. The angled slats are designed to shed wind driven rain away from the opening. Leaks are usually caused by a vent that has not been bedded and pointed correctly, rather than a fault with the vent itself.

Will a louvre vent keep out mice?
No. The fixed flyscreen fitted to this vent is designed to stop flies and larger insects, it is not fine enough to keep out mice. If rodents are a concern, a dedicated fine rodent mesh should be fitted behind or in place of the standard flyscreen.

How do I fit a louvre vent to an existing terracotta frame?
Simply unscrew or unclip the old cover from the terracotta airbrick frame and fit this plastic louvre vent using the same fixing holes. It is designed as a straightforward like for like replacement for a damaged or discoloured cover.
