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.
