Description

The Timloc 1201XL+ Telescopic Underfloor Vent is a versatile, high-performance solution for ventilating beneath suspended ground floors. Its adjustable telescopic design accommodates 5 to 7 courses of brick (375-525mm), adaptable to a wide range of construction needs.

Compatible with cavity widths from 50mm to 150mm or more, it suits both domestic and commercial applications. Constructed from durable, injection-moulded polypropylene, it resists decay for long-term use. Installed without an airbrick, it delivers a free airflow area of 8000mm2; paired with the 1201AB airbrick, it provides an effective airflow area of 6500mm2, ensuring compliance with Building Regulations and NHBC standards.

Proper spacing of no more than 2m between vents is recommended for cross-flow ventilation. It fits cavity walls with external leaves of 100-102.5mm and aligns with the ground-level DPC. Fully compliant with BS EN ISO 9001 and 14001 standards.
