Perfectly balanced casements

With casement windows, balance is everything. Too much frame and that’s all a homeowner sees. Too little frame and there’s no strength. Optima has been engineered to provide the slim, aesthetically-pleasing look that customers want, but it’s strong enough to be made into almost any configuration. The central Eurogroove that adds to the window’s security also gives it structural rigidity. The extra overlap on the frame protects from the weather and increases the glass to frame ratio. And that’s not all – we’ve located our wall thickening in just the right places to make hardware positioning easy and improve screw retention. A 70mm depth outerframe means easier installation and less making good for the vast majority of projects and a great selection of purpose made ancillaries, mean that the basic frame can be customised to suit the job.
