Save time and manufacture excellence with the enhanced Tritus™ flush casement window system


As ideally suited to Retro-fit projects as they are in new builds, flush casement windows are an increasingly popular choice with homeowners across the UK.

Getting the exact finish and feel, time after time can be challenging and time consuming. But thanks to the launch of our enhanced Tritus™ System not only can you manufacture consistently high quality flush casement windows, but you can save valuable time in the process.

In fact, we believe our enhanced Tritus™ system is the most efficient way to manufacture traditional flush casement windows today.

With greater choice and performance, our extended Tritus™ System features:

  • A range of new keeps in stainless steel finish for added durability when used with acidic timber or in coastal locations

  • Bronze finish options for handles, hinges and screws*

Efficiency and Excellence Combined

Incredibly quick installation is achieved with the standard 17.3mm x 3mm groove in the sash and 12mm x 3mm groove in the frame. And with the timber sections able to be pre-processed, the system reduces manufacturing times significantly.

What’s more, all ironmongery and accessories are simply located into the grooves, increasing productivity.

The key benefits of the enhanced Tritus™ system include:

  • Speed and Simplicity - incredibly quick and easy window installation and easier to maintain thanks to the Lift off butt hinge option

  • Ideal for windows in Conservation areas with simple and traditional looking sections

  • Tapered Ear Hook Espag - delivers maximum weatherseal compression

  • Flexibility – manufacture multiple window configurations using the same 2-groove system

  • Available in side or top hung configurations and as single or pairs of sashes

  • Save 15 – 20 minutes production time per opening light during manufacture

In addition to the new Bronze finish, the FH70 Lift-Off Butt Hinge is also available in Satin Stainless Steel, Polished Stainless Steel, Polished PVD Brass, Silver, Black and White finishes. The Satin and Polished Stainless Steel, Bronze and PVD Brass finishes are made from blu's 316 Marine Grade Stainless Steel to further increase the performance of your window system - an excellent choice for use with acidic timber and in locations on or near the coast.
