Let’s get into it…
Understanding Air Bricks and Their Purpose
To maintain a healthy ventilation system in a home, air bricks circulate air beneath floors and within cavity walls, preventing damp and condensation. While essential for air flow, their open design can inadvertently provide an entry point for rodents seeking warmth and shelter. It is a challenge for homeowners to secure these openings without compromising their primary function.
It is evident that there is a need for a solution that can deter pests while maintaining air circulation. This is where The Mesh Company’s air brick covers come into play, offering a solution that protects homes without restricting ventilation.

Why Choose 304 Stainless Steel?
When it comes to selecting material for air brick covers, 304 stainless steel stands out due to its corrosion resistance and strength.
304 stainless steel is known for its strength and resistance to corrosion, making it a durable choice for outdoor use. 304 stainless steel maintains its integrity and aesthetic appeal over time, unlike other materials that may rust or degrade. Durability, maintenance ease, and environmental resistance make it superior to alternative materials


Features of Perforated Air Brick Covers
Air brick covers from The Mesh Company are meticulously crafted from SS304 stainless steel. The covers feature 2.5mm round holes set in a 4mm triangular pitch, with a thickness of 0.6mm, ensuring robustness while maintaining a sleek profile. This design achieves a 36% open area percentage, which strikes an optimal balance between preventing rodent access and allowing sufficient airflow. Perforated covers play an important role in preventing pests from entering homes because the holes are precisely calibrated to block entry without hindering ventilation, which is crucial to preserving a home’s air quality and moisture content.
In terms of installation and maintenance, ease of use stands out as a key advantage. SS304 ensures not only longevity, but also low maintenance, corrosion resistance, and easy cleaning, requiring minimal maintenance to maintain their appearance and functionality. Combining these features underscores the Mesh Company’s commitment to providing homeowners with practical, durable pest control solutions.


Installation Guide for Stainless Steel Perforated Air Brick Covers
Here’s a concise guide to installing these panels, available in various dimensions including 100mm x 250mm, 170mm x 250mm, and 250mm x 250mm.
Preparation: Measure your air brick to determine the size of the cover and select the mesh sheet size that best covers this opening, allowing a little space on either side to secure it to the brickwork. . Make sure the area around the air brick is clean and free of debris or dust before installing it.
Selecting the Fixing Method: You can either screw the cover into place or use silicone adhesive. For external applications, screwing is recommended, while silicone adhesive can be used for a less invasive installation, suitable both for internal and external applications.
Positioning the Cover: Check the fit by holding the cover against the air brick. Mark through the 2.5mm holes on the wall or air brick where you’ll need to drill if you’re using screws. On the back side of the panel, apply a silicone bead around the perimeter.
Securing the Cover:
- For Screwing: Drill any pre-marked holes, then align the cover over the air brick and screw it into place. To prevent warping, tighten screws snugly but do not overtighten.
- For Adhesive: The panel should be pressed firmly against the air brick, ensuring even contact with the silicone. To secure the bond, hold it in place briefly.
Final Inspection
Check around the edges to ensure there are no gaps or loose areas where pests may enter. Ensure the silicone has cured according to the manufacturer’s instructions before considering the installation complete for adhesive installations.

Protecting Your Home Beyond Air Bricks
To safeguard your home against rodent intrusion, it’s essential to adopt a comprehensive pest-proofing strategy that includes air bricks. There are many vulnerabilities around your home that rodents can exploit, including gaps under doors, cracks in foundations, and openings around pipes and cables. Consider adding additional protection measures such as door sweeps, sealants for cracks, and mesh covers for other vents and openings to your home to make it impenetrable.
In addition to physical barriers, environmental strategies can also be used to deter pests. Keep the exterior clean and free of debris and nesting sites, secure rubbish bins, and trim vegetation away from the house. Identifying and repairing potential entry points promptly requires regular inspection and maintenance of your home’s exterior.
When combined with a holistic pest-proofing strategy, stainless steel air brick covers can significantly enhance your home’s defense against rodents. In order to secure every possible entry point, The Mesh Company offers a variety of mesh products suitable for different applications.
