Royale Putty-Line Heritage Windows

The Royale Putty-line is one of the slimmest thermally broken Aluminium windows on the market. Designed specifically to replace traditional putty glazed Steel windows - featuring a 45¡ putty-line detail, they look almost identical to the windows they replicate. They exceed the new build and replacement building regulations. With high security locking, the latest in-line polyamide thermal break and high performance Krypton gas filled sealed units, they will provide a huge improvement on your old steel windows.

The aluminium frame is just 33mm deep, allowing for a quick and easy like-for-like replacement, without the need to cut back Plaster, brick work or existing Timber sub-frames. They will provide a quick, easy and sympathetic solution, without the compromise, and yet cost far less than replacement steel windows. Our Royale Putty-line windows are the perfect aluminium steel replacement window system.
