Description
Installation
The XT sealing system comprises an elastomeric
modified butyl rubber adhesive laminated to a 40
micron thick malleable aluminium foil and covered with
a silicone treated paper for ease of application.
The XT sealing system combines the quality of
solvented sealants with the speed of application
provided by tapes in a single product. It is suitable for
both internal and external duct joint sealing and
provides a high initial tack with a bond, which increases
in strength over 24 hours!
Due to its flexibility, duct runs may be assembled on
the floor and then lifted into position without the tape
cracking or peeling.
The XT sealing system can also be used for roof
flashing and repair jobs. No special application skills
are required and drying or heating is not needed - Just
press the tape down firmly into position by hand!
Trim tape to required length allowing for an overlap of
50 - 100mm dependent upon duct diameter. Peel back
release paper and press tape firmly into position by
hand, especially into seams, etc.
The joint will be airtight immediately.
Surfaces to be sealed must be clean and dry moisture will seriously affect adhesion.

Lindab XT sealing system has been tested by BSRIA
(Test Report 17875/1) and was found to have a leakage
rate less than class C in accordance with DW144.
The XT sealing system is also ideal for jointing and
sealing flexible duct connections without the need for
clips. For this application we recommend that a
minimum tape width of 75mm is used. Care must be
taken to ensure that the flexible duct is adequately
supported.
