The Optima System by Profile 22 is a fully-integrated, 70mm system for casement windows.

The system meets all requirements for thermal efficiency as standard. A wealth of intelligent design features plus double and triple glazing options mean thermal efficiency can be enhanced to meet your project’s specified standards, up to and including 0.8 W/m²K or A++.

It also offers market-leading structural strength and security. Secured by Design requirements can also be met where required.

Casement windows are suitable for almost any size or layout of casement window and the system includes all the components for bay and bow windows and conservatories. The French Casement Window option offers the ideal alternative to traditional timber window designs or windows with smaller apertures.

The system comes with the widest range of ancillaries in the industry so you can create perfect projects every time.

Traditional, outwards-opening styling is updated with modern, durable, easy-to-maintain materials, secure and reliable hardware and thermal performance that can reach the U-values required by Passivhaus standards – all this, in a system that has been designed for efficient fabrication and trouble-free fitting.
