TXTHeavy duty Tectape

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!
