The Redbank 351 square hole air brick in red clay measures 215 x 140mm and is designed for controlled ventilation in building projects. The square hole pattern assists in maintaining consistent airflow into internal spaces while also offering a neat appearance in brickwork.
This air brick is typically installed in external masonry walls to ventilate underfloor voids, suspended timber floors, or cavity walls. Its robust clay material and standard sizing make it suitable for integration into both new builds and refurbishments where dependable ventilation is required.
