The aluminium profile which we use is suitable for both domestic and commercial applications, for either new build installations or as replacement windows.  Our energy efficient windows have all been developed to deliver the perfect combination of stylish looks, outstanding performance and to reduce heat loss from your property.

CMC Aluminium windows are constructed from aluminium alloy, which are designed to offer excellent weather resistance. They feature a polyamide ‘thermal break’ between the inside and outside frames to provide excellent insulation properties. All our aluminium window profiles allow you to enjoy the comfort of improved insulation as well as lower energy bills.

The range of colour and finish options of the aluminium window which we offer, provides inspiration for all types of properties. The frames are powder coated to a colour of your choice and can be a different colour inside to outside, called dual colour. From contemporary homes to traditional Peak District cottages, we have the perfect colour to suit every project. Whilst Black window frames are becoming increasingly popular, the most requested colour at the moment is anthracite grey Ral 7016.

How much do aluminium windows cost?

By purchasing from CMC Aluminium you are dealing direct with the fabricator. This cuts out suppliers in the chain. CMC Aluminium are specialist glazing and aluminium fabricators, and we have been in business for 25 years, with an excellent reputation.

The fewer suppliers involved, the less times the window frames are marked up and hence represent better value for your money.  Many installers in the market place buy from a fabricator and then mark up the aluminium windows. The more companies that are involved in the supply chain the more  margins are added to the final price. Why not check out our prices, we do offer a no obligation quote.

Do I need planning permission to install aluminium windows?

It’s unlikely that you’ll need planning approval to install replacement windows and doors, but if you do, we can utilise specific systems to meet the requirements of sensitive new build or refurbishment projects – even for buildings that are listed. We are happy to discuss your individual project and offer advice on the most suitable options.

Order directly from us.

By dealing directly with CMC Aluminium you are dealing with the fabricator of the aluminium windows. We will fabricate and install the aluminium windows into your property.  Your window frames are made in our unit in Dronfield, Derbyshire. It cuts out a trader buying the windows and put their margin or commission on before supplying them to you.  In addition when we supply the windows to a domestic buyer they come with a 10 year guarantee.  So it makes sense to deal direct. You can come along to Callywhite Lane, Dronfield to see where the windows are made and discuss your project. We have many years of experience of projects in the Peak District, Sheffield South Yorkshire & Chesterfield, Derbyshire.
