The Dualframe 75 Si Tilt-before-Turn aluminium window uses advanced polyamide thermal break technology to provide thermal performance without the need to resort to complex and costly sealed unit specification.

The Dualframe 75 Si Tilt-before-Turn aluminium windows are the ideal solution for high-rise or commercial applications, combining ventilation with large span openings and easy cleaning facilities.

The specialised profile range adds great flexibility when constructing windows where inward and outward-facing rebates have to be combined, without the need and expense of coupling sections or dummy frame to fixed lights. Universal frames can be used to create the most complex of screens easily combining casement, tilt before turn, and reversible opening lights, as well as inside and outside glazing. Combined with the option of having different finishes inside and out, the Si suite will give you endless choices.
