Case Study

Established in 1980, Customade is a specialist manufacturer of high-quality aluminium and PVCu windows, doors and conservatory roof products. Best known for its proprietary and market-leading REAL, Atlas and Fineline aluminium brands, the company operates from 100,000 square foot, state-of-the-art production and storage facilities near Gloucester. In 2016 it employed 320 people and achieved turnover in excess of £35 million.

Following earlier investments in Polyframe, WB Group, and Stevenswood’s manufacturing facility, the Customade acquisition was Cairngorm Capital’s fourth proprietary, off-market transaction in the window and door manufacturing sector since July 2016.

Customade subsequently merged with these three other Cairngorm Capital businesses, to create Customade Group – the UK’s largest independent trade windows and door manufacturer with the industry’s most comprehensive product offering, over £100m revenues, 900 employees and 10 manufacturing sites.

This development of the Customade Group is consistent with Cairngorm Capital’s strategy of investing in well-performing UK companies to support ambitious management teams in driving transformation, introducing new technology, broadening customer offerings and extending geographic reach.
