Product Information

Full details

This Rytons Airbrick Cowl in white is designed for homeowners and builders needing to protect external wall openings from harsh weather. Its primary benefit is preventing excessive rain and wind from entering cavities, while also mitigating air blasts. A potential consideration is that its '9x9' nominal size is larger than the opening to ensure coverage, so confirm measurements for your specific application.

FAQs

What does '9x9 nominal size' mean?

It refers to the standard size designation for air bricks and similar openings. The Rytons cowl is designed to cover these standard openings, but its actual dimensions (274mm L x 235mm H) are larger than the nominal opening to ensure it can overlap and cover the surrounding area effectively.

What materials is the cowl made from?

The cowl is made from a durable, U.V. stabilised plastic with a textured roughcast finish.

Can I paint the cowl?

While the cowl is U.V. stabilised, painting it may affect its appearance and longevity. If painting, use a paint suitable for exterior plastics and test in an inconspicuous area first.

How much airflow does it allow?

The cowl offers a free area of 23,900mm² (239cm²) per unit, ensuring sufficient ventilation while protecting against weather.

What is the purpose of the textured finish?

The textured roughcast finish helps the cowl blend in with common exterior wall finishes like rendered or pebbledash walls.

Does it come with fixings?

No, the Rytons Airbrick Cowl does not typically include screws or wall plugs. These should be selected based on your specific wall construction.

What are the overall dimensions?

The total dimensions of the cowl are approximately 274mm in length, 235mm in height, and 103mm in depth.

Troubleshooting

Cowl appears loose after installation

Ensure appropriate fixings (screws and wall plugs) are used for your wall type and that they are tightened securely. Re-check that the cowl is properly seated against the wall surface.

Water ingress despite cowl installation

Verify that the cowl is correctly positioned and sealed around the edges. Check for any cracks in the cowl itself or the surrounding wall. Ensure fixings are watertight.

Excessive debris accumulation

Clean the cowl regularly. The free area is designed to allow airflow, but blockages can still occur. Manual cleaning may be required periodically.

Pros and Cons

Pros

  • Provides excellent protection against wind and rain ingress.
  • Helps to improve building energy efficiency by reducing drafts.
  • UV-stabilised material ensures longevity and colorfastness.
  • Textured finish offers a discreet aesthetic.
  • Oversized design accommodates variations in brickwork or existing openings.

Cons

  • Requires careful measurement to ensure correct fit despite oversized design.
  • Primarily designed for external surface mounting.
  • White color may show dirt more readily in some environments.
  • Weight of 0.35 lbs, while light, should be considered for mounting security.

Setup, Compatibility & Care

Setup:

  1. Ensure the mounting surface is clean and dry.
  2. Position the cowl over the existing air brick, grille, or vent opening, ensuring it overlaps sufficiently on all sides.
  3. Secure the cowl to the wall using appropriate screws and wall plugs (not included), ensuring a firm and watertight fit.

Compatibility:

  • Designed for 9x9 nominal openings, suitable for standard air bricks, grilles, and vents.
  • The larger dimensions (274mm L x 235mm H) allow it to cover openings up to this size, plus a margin.

Care:

  • Clean periodically with a damp cloth to remove dust and grime.
  • Avoid using abrasive cleaners that could damage the finish or material.
  • The U.V. stabilised material requires no special maintenance against sunlight.
