Description

The GT55 commercial door system gives the option of both thermal and non-thermally broken doorsets. The doors can be integrated with AluK ground floor treatment systems and are suitable in high traffic environments. They can accommodate both double and triple glazing.


The GT55 TB is a thermally broken aluminium commercial door system provides exceptional security and performance. It delivers high levels of energy efficiency due to its thermally broken profiles and it has been designed in a ladder frame construction to provide a flexible solution for low-rise glazing applications. The GT55 NI door provides high security and is suited to high traffic environments where no insulation is required. The system has been fully tested with full glazing, no use of steel reinforced panels, as well as with semi-glazing.
