Sentry Doors Limited has announced the acquisition of E. & S. W. Knowles & Company Limited in a bid to accelerate its growth and become the UK’s leader in timber fire safety and security doorsets.

This acquisition will add new products complementing Sentry Doors’ product range, focused on the specialist fire doorset requirements of the social housing, public sector, commercial and residential markets.

Established in 1923, E. & S. W. Knowles manufactures specialist timber internal doorsets with fire rated, acoustic and PAS 24 security certification. Knowles employs approximately 100 people and in 2021, achieved revenue of £10m.

Both companies are set to benefit from the possibilities offered by their new market sectors and an expanded range of products and finishes. The enlarged business continues to be headquartered in Doncaster.

Ty Aziz, Sentry’s Chief Executive, said: “I am delighted to welcome Knowles to Sentry Doors – they have a fantastic manufacturing heritage, an exceptional team and a superb product range so we can learn a lot from one another.

“This partnership will help us to respond to the surge in demand for our products, as well as providing our customers with a fully comprehensive range of fire safety and security solutions, and a greater choice of features and finishes. It marks a key milestone in the growth strategy for our businesses and advances our collective ambition to be UK leaders in this sector.”

Martin Wright, majority owner of Knowles, added: “Next year Knowles celebrates its centenary and while I am extremely proud of all that we have achieved in the last 99 years, I know that the company has the capability to achieve much more in the future.

“I believe that this is the natural point for me to pass the company to new, trusted custodians who can deliver on its future potential. Knowles has a perfect partner in Sentry and together, the companies should achieve great things.”
