Provides cranked air-duct route from cavibrick to area at different level.

Introduction

The Telescopic Adjustable Underfloor Ventilator extends or contracts like a telescope. It extends to a maximum of five brick courses.
It is designed to accommodate the high performance cavibrick, or may alternatively be used with a conventional air-brick.

Airflow can be directed to a specific area of the structure,at a different level.
Where a greater variation is required beyond five courses, an intermediate sleeve is available to extend the range.

The Type TAV offers an unobstructed airflow route to promote best practice. An accompanying DPC cavitray is also available to order, to provide damp proofing integrity as defined within the Building Regulations.
