Operating well-established and recognised brands including K Rend and K Systems, Kilwaughter operates one manufacturing facility near Larne in Northern Ireland and employs about 200 people with a strong focus on technical expertise and system specification. It generated revenues of around £50 million in 2024 (fiscal year ending April) and will be consolidated into the Northern Europe Region.

Closing of the transaction is expected in the first half 2025 and is subject to the satisfaction of customary closing conditions.

Saint-Gobain said the acquisition is in line with its strategic plan, “Grow & Impact” which aims to both strengthen the group’s leadership and accelerate its growth by enriching its range of solutions for light and sustainable construction.

Mike Chaldecott, CEO Saint-Gobain UK & Ireland, said: “The acquisition of Kilwaughter, which is now subject to competiton clearance, is a great fit for Saint-Gobain. Kilwaughter will provide us with an even greater range and capacity to provide our customers with lightweight construction solutions for lightweight building facades and envelopes that make buildings better for occupants and the planet.

“Kilwaughter has a wide range of systems and a strong reputation for quality and great brands in K Rend and K Systems. They also share many of the same priorities of Saint-Gobain: a focus on technical expertise and quality; innovation; supporting customers with training and specification support; a deep commitment to sustainability and; as an employer, providing great careers where personal development and well-being are prioritised.”
