Introducing our Optima

Casement Windows

Optima C is a 70mm system with a chamfered design, suitable for the production of casement windows, Tilt and Turn, French casements and residential and French doors. The slim, chamfered shape is clean, attractive and suitable for a wide range of projects.

The ever popular casement window is better than ever when made using Optima’s slim, chamfered profiles. Almost any size or layout is possible, and there are all the components required for bays, bows and conservatories. Frames can be customised to suit modern or period properties and the system is equally suitable for residential, commercial, education or healthcare projects.

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.

Casement Window Specifications 

These 70mm depth, integrated open-out windows are available in a variety of single or multi-light styles, using top hung vents, side hung casements and fixed lights, either internally or externally glazed, available in 28 colours with a variety of dual-colour options, fabricated to BS 7412. Round head, circular or lancet windows (Gothic arched) may be supplied depending on size, style and application.
