Flush Windows

Our uPVC flush windows offer up-to A++ rated energy efficiency and come with Q-Lon weatherseal gasket and shootbolt locking as standard.

Furthermore, we offer a wide selection of foil and finishes, and a range of handles, accessories, and glazing. Whatever the style and character of your home, Northdown Windows has you covered.

Worried about rising energy prices this winter?

Our windows are rated up-to A++ for more energy efficient use, meaning you could save hundreds a year on your energy bill.

Already have double-glazed windows?

Did you know that most double-glazed units are only guaranteed for 10 years? Gradually, the seal breaks down and this allows condensation to get inside the glass unit resulting in misting.

Broken sealed units are leaking expensive energy out from your home – but not to worry, with our team of expert fitters, replacing broken down seal units couldn’t be easier! You don’t even need to change your window frame, just the glass unit itself!
