Timloc's 9x3 Through Wall Cavity Sleeves for 1 Airbrick are engineered to establish consistent ventilation between your building's interior and external walls. Specifically designed for a single Airbrick (9" x 3"), they provide unrestricted free airflow. With a lightweight and easy-to-handle design, they boast excellent durability and resistance to decay.
Each sleeve is suitable for walls with a thickness of 275mm. For thicker walls, you can easily connect two sleeves by joining the ends and trimming them accordingly. With a maximum area per cavity sleeve of 6170mm², they are a practical and reliable choice. It is essential to pair these sleeves with Timloc's Airbricks.
If you require a wider cavity application, you should use a telescopic extension. To prevent any unwanted water intrusion, it is highly recommended to install a Horizontal Cavity Tray above the Airbrick and Cavity Sleeve, ensuring comprehensive protection for these accessories.
