What we do

At Trident we specify and supply high performance windows and doors, sourced from the leading European fenestration manufacturers, for architecturally designed projects throughout England and Europe.

With a firm belief that life should be about choice not compromise, excellence over mediocrity, Trident exists to offer architects an unbiased independent service that delivers unprecedented choice to create ultimate glazing packages that express, impress, protect, perform, and secure.

Passivhaus Products

The growth of the passivhaus movement challenged manufacturers to design and develop glazing systems that met the demands of Passivhaus standards and methodology. For high performing passivhaus and passivhaus plus properties, Trident can advise on the best glazing systems to use and the way in which to use them.


Windows are one of the most visually expressive and integral features of any building design. They can be blended seamlessly into a structure or to make a bold statement. Trident is proud to be official partners of Rationel, and together with longstanding partnerships with Velfac, Schuco, Solarlux, Maxlight, and Skyframe, can create the ultimate glazing package for any bespoke project.


To welcome, walk through, or to simply shut out the world. Steeped in historical and metaphorical meanings, doors are often one of the most visual focal elements of any project yet more often than not the most difficult to get right. Attention needs to be paid not only to aesthetics but security, durability, accessibility, and often the most difficult element… the colour!
