Backed by over 120 years' experience in manufacturing Caldwell delivers quality, design-led hardware solutions to PVCu, timber, aluminium and composite window fabricators.

We manufacture a comprehensive range of products including traditional sash window hardware and balances, and hinges and restrictors for more contemporary window styles such as pivot.

Our window hardware can be manufactured for all materials and systems, and can be incorporated in windows for installation in a variety of projects from domestic through to heavy-duty commercial applications.

Caldwell offers standard and customised options but most of our solutions are made bespoke to the client through our in-house design process and manufacturing facilities.
