CMC Aluminium are glazing specialists and aluminium specialists. Our windows are windows constructed from aluminium alloy, which are and designed to offer excellent weather resistance and featuring a polyamide ‘thermal break’ between the inside and outside frames to provide excellent insulation properties. All our aluminium window systems will allow you to enjoy the comfort of improved insulation as well as lower energy bills. Our range of colour and finish options 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. From contemporary homes to traditional Peak District cottages, we have the perfect colour to suit every project in any location.

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.  The less suppliers involved the fewer times the products is marked up and hence cheaper to you.  Many installers in the market place buy from a fabricator and then mark up the aluminium windows. The more companies involved the more profit margins are added to the final price. We do offer a no obligation quote.


Aluminium_WindowDo I need Planning Permission?

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 and refurbishment projects – even for buildings that are listed. We are happy to discuss your individual project and offer advice on the most suitable options.

What does cut out the middleman mean?

windows made to orderBy 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.  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.




The windows are internally beaded for security purposes and have multipoint locking systems. Internally beaded top hung and side hung sashes have successfully tested to BS7950.  PAS24 - you can find out more about security.
