Dualframe Si Balcony Window

High Performance Windows
Developed upon the Dualframe 75 Si Tilt-before-Turn window, the Dualframe 75 Si Balcony window offers inward and outward openings with single and double door options. Ideally these windows are suited to the increasing use of Juliet balconies alongside the traditional full balcony. Available with standard and low thresholds, this system provides exceptional performance thermally and for Air, Wind and Water Resistance. The Dualframe 75 Si Balcony Window is suited for Juliet and other standard balcony applications. As with all Dualframe 75 Si windows, the aluminium Balcony window system was designed to achieve high thermal performance without foams or resorting to costly and complex sealed unit specifications. 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.
