The Royale Putty-line is one of the slimmest thermally broken aluminium windows on the market (just 33mm deep). Designed to replace traditional putty glazed steel windows, with a 45° putty-line detail. Featuring high security locking, the latest in-line polyamide thermal break and high performance Krypton gas filled sealed units, they exceed the building regs. for both new build and replacement projects.
A quick and easy like-for-like steel window replacement, without the need to cut back plaster, brick work or existing timber sub-frames. A sympathetic and vast improvement over steel, yet costing far less than any replacement steel windows.
