Homeowners with Listed properties, or houses that fall inside Conservation Areas and Areas of Outstanding Natural Beauty, will often find their local planning authority is happy to approve the use of Crown windows and doors due to the super-slim frame design.

Our Crown windows use ‘True Dual-Colour‘ technology affording a palette of over 400 colours for the inside and outside of your windows, to blend or contrast with your home as you wish. The finish is a high performance, non-fading, hard and durable coating that is baked onto the frames. Being low maintenance, it needs only an occasional wipe down to stay looking as good as new.

Finally, your Crown windows can be finished with an inspiring array of Georgian, leaded, patterned or stained glass to highlight distinct aspects of your home, add character or control privacy. A long working life and the greenest credentials

Designed and manufactured to high quality industry standards, Crown windows and doors won’t warp, twist or swell and will never rot or rust. Whilst nothing is completely ‘fit and forget’, the maintenance required to keep your Crown windows and doors performing and looking as good as the day they were installed, is genuinely minimal.

The latest UK Building Regulations for windows and doors place high demands on thermal efficiency, which is why the integral thermal efficiency of the Crown system not only meets, but exceeds the required standard, saving you money on your energy costs every single day.

Aluminium is something of a wonder material which is why it is used in so many different ways. Once it has come to the end of its useful life it can be recycled again and again and again – in fact it can be re-used infinitely, which makes it one of the greenest building materials available.

Maintenance-free Frames

  • 75% of all aluminium produced since the 1880s is still in use
  • 70%-98% of aluminium used in today’s buildings will eventually be recycled
  • The fundamental properties of aluminium do not change after recycling – a unique property compared to other materials
  • Primary source is Bauxite, one of the earth’s most abundant natural resources
  • Mined from resources close to the surface
  • 50% of aluminium smelting from bauxite uses hydro-electric power.

Secure by design

Exceptional quality and good looks require exceptional security. Our windows and entrance doors meet crucial industry and police approval standards, to give you total peace of mind.

Security has always been at the forefront of Monarch window and door design and we understand that security equals peace of mind. This is why we incorporated high performance, multipoint locking AS STANDARD into all of our windows and doors, which meet and exceed two crucial industry security standards – BS7950 for windows and PAS24 for hinged entrance doors. Your insurance company will be satisfied as our Crown system fulfils the Police Approved Specification as ‘Secured by Design’.

Our security features coupled with the inherent strength of aluminium makes Crown windows and doors a truly secure choice for your home. Your home is simply and effectively secured through high strength, multipoint locks engaged with one simple handle action and a central key.

Crown hardware fits with anyone's personal living or furniture style

Styling is all about taking care of the details, and the handles of your windows and doors have been as carefully thought through as every other aspect of the Crown system. Designed and manufactured for us, by one of Europe’s leading brand of door and window handles, we offer an extensive and imaginative range of handle colours to complement or contrast with the frame colour you choose and, crucially, all of our handles are colour matched so your windows will always match your doors – we know it’s only a small thing, but we believe it’s this attention to detail that really counts.


Crown windows and doors have been developed by Sapa Building Systems who are part of the worldwide Sapa Group with over 13,000 employees in 30 countries, with over 50 years researching and developing window and door systems. The passion and commitment for exceptional quality is assured through the many professional accreditations, certificates and licences that we have been awarded and is your guarantee of the finest windows and doors.
