Royale Steel Replacement Windows

At just 32.5mm front to back, our new Royale Steel Replacement Windows are the slimmest thermally broken aluminium window system on the market. With such slim profiles replacing steel windows has never been easier - with no cutting back of plaster, brick or wooden sub-frames, speeding installation and reducing costs.

Our Royale Windows use the latest polyamide thermal break, which makes them highly thermally efficient. They exceed the current building regulations with excellent thermal values.

The window is not only thermally efficient, but it is also highly secure with the accreditation of Secured by Design, with modern high security locking.

We also can provide a range of authentic hardware which includes modern multipoint locking or Cockspur locking with peg stays.
