Provides cranked air-duct route
from cavibrick to area at different
level.
introduction
The Telescopic Adjustable
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.
