Product Overview
Plastic Air Brick in a black finish, measuring 229mm × 76mm (9" × 3"), designed to provide permanent ventilation for subfloor voids, cavity walls, and general building applications.
Manufactured from robust polypropylene for strength, weather resistance, and long service life with no risk of rust or corrosion.
Lightweight, easy to handle, and simple to install into standard brickwork openings. Ventilation grille layout delivers consistent free airflow while preventing ingress of debris and pests.
Suitable for both new build and refurbishment work, offering a practical, low-maintenance alternative to traditional clay air bricks.
Neutral black finish suits contemporary brick and render finishes for discreet ventilation detail.
Features & Benefits
- Durable plastic construction: Resists corrosion, frost, and weather exposure without deterioration.
- Precision-moulded grille design: Provides consistent airflow and prevents blockage by debris or vermin.
- Standard brick size: 229mm × 76mm format fits standard 9" × 3" coursing for simple integration.
- Lightweight and easy to install: Slots directly into masonry with minimal preparation or tools.
- Maintenance-free finish: Requires no painting or surface treatment for long-term performance.
- Colour finish: Black colour coordinates with surrounding brickwork.
Applications
- Subfloor ventilation: Provides airflow beneath suspended floors to prevent damp and timber decay.
- Cavity wall ventilation: Ensures circulation within wall cavities to minimise condensation.
- Outbuildings and garages: Suitable for general-purpose ventilation in non-habitable spaces.
- Refurbishment and replacement: Ideal retrofit option for upgrading corroded metal or clay vents.
- New build integration: Compatible with plastic ducting and extensions for continuous airflow paths.
Installation Guidance
- Preparation: Fit within standard brickwork openings at required ventilation spacing.
- Fixing: Mortar into position or secure with mechanical fasteners where appropriate.
- Alignment: Maintain unobstructed airflow; align horizontally for even ventilation.
- Combination: Can be paired with cavity sleeves or telescopic underfloor vents for extended air paths.
- Maintenance: Inspect periodically to ensure grille openings remain clear of debris.
Compliance & Performance
- Material specification: Injection-moulded polypropylene.
- Dimensions: 229mm × 76mm (9" × 3") standard air brick format.
- Ventilation design: Grille profile provides consistent free area airflow.
- Durability: UV- and frost-resistant; suitable for external use in UK conditions.
- Important note: Ensure clear airflow paths and appropriate spacing for required ventilation rate.
