Tectherm 400 is manufactured using Tecflex
400 as the inner core, wrapped in a 25mm
thick high density fibreglass blanket which
is overlapped to ensure continuity of
thermal insulation (50mm thick fibreglass
blanket also available). The insulation is
then covered by a tough scuff resistant,
reinforced aluminium and polyester
laminate which acts as a vapour barrier.
The use of Tecflex 400 as the inner core
completely shields the airstream from the
fibreglass insulation. This, together with
highly automated insulating machinery
ensures consistency of product quality. The
exceptionally smooth inner wall of the
ducting provides for excellent friction loss
characteristics and reduced levels of noise
generation.
This construction results in a highly flexible
duct in which bends of 1.2 D radius can be
produced.
Specification
Insulated flexible ducting for joints or
connections shall be TECTHERM 400. It
shall be manufactured using Tecflex 400 as
the inner core and wrapped in an
overlapped high density fibreglass blanket
25mm (50mm optional) thick and covered
with a tough scuff resistant reinforced
aluminium fabric jacket acting as a vapour
barrier. The duct shall meet the
requirements of BS476 parts 6, 7 and 20. In
respect of part 20 the duct shall have a fire
resistance of not less than 30 minutes.
Packaging
Each 10 metre length of duct is individually
cartoned and labelled. This production and
packaging configuration ensures that
wastage through scrap is kept to a minimum
and dramatically reduces the chance of
damage in transit or on site. Storage space
required is also kept to a minimum with a
10 metre length being compressed to
1160mm.

Installation
Fully extend ducting, then cut to exact
length required using a sharp knife and
pliers/wire cutters. To fix Tectherm 400 to
spigots we recommend the Tecfix banding
or clip system. When
installing Tectherm 400, securely clamp the
inner core first and then tape or clamp the
outer jacket and inner core to the spigot.
Taping the outer jacket to the spigot will
prevent any fibre migration.
