Dualframe SI 75 Casement

Dualframe 75 Si Tilt Turn window suite is the first in a new generation of window and fašade products. Utilising advanced polyamide thermal break technology, Dualframe 75 Si provides high thermal performance without the need to resort to complex and costly sealed unit specifications.

Drawing from the tried and tested design principles of Dualframe, the Si designation will be progressively rolled out across all of the main Dualframe window and fašade configurations.

The tilt/turn hardware now includes a switch barrier which prevents the unit from being left in turn mode. This is particularly important in applications where the window may be misused or damaged by unauthorised operation. Hinges are concealed within the frame, which eradicates colour matching issues and ensures a deep plaster line finish.
