Swifix Extension Tube (Pack of 10)


The Swifix Extension Tube is designed for extending the full range of Swifix fittings. The Extension tube is ideal for use where the insulation system exceeds 120mm in thickness – simply attach the tube to the Swifix fitting. This offers users the ability to secure fixings to EWI systems without causing thermal bridging and damage to the system.

Swifix Extension Tube

A cost effective, maintenance-free way of fixing items back through your EWI system, whether it’s before or after the insulation system has been installed. Swifix insulation fixings are designed to eliminate the risk of cold spots and water ingress when installing insulation fixings; this ensures that the system remains functioning optimally and the thermal efficiency of the system is maintained.

Manufactured from high quality plastics, the insulation fixings have been designed to provide an aesthetically pleasing appearance and enhance the property’s new exterior. The insulation board fixings have been tested by the BRE (British Research Establishment) for strength, compression and load bearing capabilities.
