Choose Clement and you will gain a number of advantages:

Incredible strength and security

Steel is the strongest material on the market for windows and doors, incomparable to supposedly similar products made of aluminium. Our robust hot dip galvanised steel frames have the life expectancy of the building they are fitted into.

A number of Clement windows are available with our pioneering multi point locking system - tested to BS7950, this will enhance the security of your home.

Longevity and low maintenance

All Clement premium galvanised steel windows are hot dip galvanised and are available in a choice of fabulous Akzo Nobel powder paint colours. Akzo Nobel are rightly acknowledged as the global leader in advanced performance surface coatings.

Offered with a 10 year warranty these windows provide an average paint coating in excess of 100 microns – the industry standard is 60 microns. Requiring minimal maintenance Clement windows and doors will look stunning for many years to come!

Versatility and elegant sightlines

The elegance of steel is unsurpassed. Clement galvanised steel windows have the slimmest possible sightlines on the market, bringing lots of light as well as a beautiful appearance.

High thermal performance

At Clement we are continually developing and updating our window ranges, so that we can deliver to clients a choice of products that are designed for modern living and meet the exacting standards required by Building Regulations. The inclusion of only very high quality, thermally efficient glass units teamed with innovative steel frame design and weatherproofing result in high performing windows and doors that will reduce your energy bills.


Around the world more steel is recycled every year than the total of paper, aluminium, glass and plastic combined and so you will not be surprised to learn that our steel windows, doors and screens are made from 98% recycled steel making them the ‘green’ window of choice for your project.
