Armstrong supports investment in CMS Window Systems by Maven Capital Partners

Armstrong has provided CDD for Maven Capital Partners’ MBO of CMS Window Systems.

The business is an end-to-end provider of premium window and door solutions, and one of Scotland’s fastest growing manufacturing businesses.  CMS specialises in designing, manufacturing and installing energy-efficient and environmentally-friendly products, including PVCu and aluminium, windows, doors and curtain walling systems.

The Company undertakes contracts for some of the largest housing investment programmes and commercial build projects in the UK and has long-standing relationships with many of Scotland’s local authorities to refurbish their social housing stock, and has recently extended its reach to local authorities in the North of England. CMS commands a strong market position, with the business possessing the capabilities and experience to undertake large and complex projects across all commercial, social, and private housing markets.

Armstrong provided full buyside CDD, including interviewing customers accounting for over 60% of revenue and producing upside/downside growth cases, strategic and operational recommendations.

This work built on Armstrong’s experience of 20+ transactions in the windows (e.g. Performance Timber Products, Synseal), doors (e.g. John Porter Doors, Komfort/Leaderflush Shapland) and social housing markets.
