Bay Windows
Light, depth and a place to sit
A bay window projects beyond the wall line to create genuine depth in a room — extra floor space, a window seat, and daylight arriving from three directions instead of one. Bays are also one of the defining features of Melbourne's period housing stock, and replacing a tired timber bay with double glazed uPVC is one of the most transformative upgrades available. Each bay is drawn to the specific opening, with the angles, structural head detail and sill returns confirmed before anything is made.

Profile accreditation
Northstar uses uPVC profile systems accredited under the uPVC Windows Alliance Industry Code of Practice.
The accreditation relates to profile performance and suitability for Australian conditions.
We can also supply selected uPVC window and door systems rated to Passive House standard.
