"Constructing Solutions Together"



CMC Aluminium undertakes maintenance works, domestic projects and small to medium sized commercial projects.  CMC Aluminium is now firmly established and retains a dedicated maintenance service for re-glazing and door repairs.  In the new unit CMC Aluminium is now also capable of larger projects whilst still keeping a personal touch. We are in our 24 years of business, so are an established supplier, with whom you can deal direct - no middle man adding their margin.

You will deal directly with the Directors - Mark & Nigel who care deeply about getting it right for the customer.   What ever your project entails you can be sure of the very best of our help and experience.  If you have works being done by a builder or through an architect we are happy to liaise with them too.

We employ our own team of fitters, so you can be sure that we will see the job through from start to finish.

The showroom is currently being fitted out - we do have a limited display which includes a bi-folding door if you wish to visit. If you are planning a visit, please can we ask that you call first. We are a small team and want to ensure we dedicate time to you.  Shortly we will also have a range of other doors, aluminium profiles, colours, blinds in the glazing and  sliding patio doors, which have become more popular recently.

We also get searched on the internet as CMC Windows, CMC Glass, CMC Manufacturing & CMC Systems ...

Our full company name is CMC Aluminium Systems Ltd.


We are based in Dronfield, Derbyshire

All products are fabricated bespoke to your requirements.  There are over 200 colours to choose from, so if you are looking to add character to your property or match a corporate image on a shop front we can assist.  If you are in a conservation area we can help ensure the colour meets with the regulations.

“Just wanted to express my thanks for the excellent work done by your installation team at my property today. I missed them leaving so was unable to thank them in person. We’re delighted with the product! The windows look great and I’m hugely impressed by the quality of the build and finish, the appearance and the installation. Your men were polite and courteous and worked to a very high standard.

It really has been a pleasure doing business with you.”
