About CMS Window Systems

Our ethos

'We are committed to the continual improvement of the quality of our products and services and seek to minimise adverse environmental impact whilst doing so.'

Since our inception in January 2006, at CMS we have enjoyed significant and continued success and are now listed as being one of the top companies designing, manufacturing and installing PVCu and aluminium windows, doors and curtain walling systems.

Our premises

At CMS, we employ over 300 full time staff at specialist manufacturing and recycling facilities in North Lanarkshire, South Lanarkshire and Fife. Our first class workmanship, customer care and product excellence have ensured we remain at the forefront within our industry.

Our products

Our product range is manufactured in resource efficient factories using systems from world leaders including Yale, Duraflex, Liniar, Glassolutions Saint-Gobain, Metal Technology and Kawneer – and is designed to maximise energy performance in use and be of exceptional quality.

PVCu has a Green Guide ‘A’ rating, reinforcing the material’s place in sustainable construction and with our state-of-the-art manufacturing and recycling facilities we are set-up to produce first-class, sustainable products to suit any size of project.

Our clients

We work directly and on a subcontracted basis with many local authorities and housing associations on refurbishment and new build contracts. In the house-building and commercial development sectors we work with some of the biggest names in UK construction.

We also provide a wide range of windows and doors for trade installers, perfect for residential new builds or replacement projects.

Our commitment to exceptionally high standards of quality, service and aftercare ensures we build long standing relationships with our diverse client base.


Together with our supply chain partners we have been at the forefront of innovative developments and award-winning practices within the building and housing industry to create energy efficient and environmentally friendly products and systems that not only benefit our customers but have minimal negative impact on the environment too.
