Product Overview
Square Hole Clay Air Brick in a buff finish, with a 65mm height and 215mm length, manufactured from high-quality fired clay for permanent, maintenance-free ventilation.
Designed to provide efficient airflow to underfloor voids, cavity walls, and structural spaces, preventing moisture build-up and condensation. Precision-moulded square perforations allow consistent airflow while maintaining structural integrity and weather resistance.
Natural clay composition ensures strength, frost resistance, and colour stability for long-term exterior use. Suitable for traditional and modern brickwork, coordinating with standard masonry coursing and aesthetic finishes.
Standard single-course height for typical subfloor ventilation and cavity wall airflow. Light buff colour suited to contemporary and lighter brick façades for visual continuity.
Features & Benefits
- Durable clay construction: Fired at high temperature for long-lasting strength and weather resistance.
- Square hole design: Ensures free airflow while maintaining stability and protection against ingress.
- Colour-stable finish: Natural clay pigmentation resists fading and blends seamlessly with facing brickwork.
- Frost and weather resistant: Suitable for external exposure in all UK climates.
- Easy to integrate: Matches standard 215mm brick lengths for quick alignment during installation.
- Size and ventilation capacity: Standard single-course height for typical subfloor ventilation and cavity wall airflow.
Applications
- Subfloor ventilation: Allows consistent air circulation beneath suspended timber floors to prevent damp and decay.
- Cavity wall ventilation: Provides continuous airflow in wall cavities to reduce condensation risk.
- General building ventilation: Suitable for garages, outbuildings, and structural air spaces.
- Restoration and heritage work: Matches traditional clay facades and coursing.
- New build integration: Fits modern cavity wall and insulation systems with standard coursing dimensions.
Installation Guidance
- Positioning: Install evenly along wall base or ventilation line for balanced airflow.
- Alignment: Maintain brick coursing; avoid obstructing openings with mortar or debris.
- Combination use: Can be paired with plastic or clay ducting to extend airflow paths.
- Weather protection: Fit with compatible grilles or cowls where required to prevent water ingress.
- Maintenance: Inspect periodically to ensure openings remain free of obstruction.
Compliance & Performance
- Material specification: Fired clay, frost-resistant, colour-stable.
- Dimensions: 215mm standard brick length with 65mm height.
