Optima is an efficient to fabricate and easy-to-fit system designed and made in Britain for the British market.
It was developed to look better and perform better than any other system, giving you a clear competitive advantage whether you work in the domestic replacement, new build, refurbishment, commercial or public sectors.
Optima isn’t one system, it’s three: a Chamfered System, a Sculptured System and a Flush Casement System. All three are complete and are fully integrated. They incorporate features that other systems lack but don’t use gimmicks or quick fixes. They include all the refinements and improvements you would expect and some that take it to a whole new level. In short, we believe that Optima is the best PVC-U system available today.
The thermal efficiency is exceptional. The 6-chambered outerframe and 5-chambered sash can be used with RCM thermal inserts to increase the number of insulating chambers, delivering optimal thermal performance and structural rigidity. Revolutionary additional centre seals to the outerframe and sash give outstanding insulation and weather protection. The system has the widest range of glazing options on the market (24-44mm), including triple glazing in three sizes. Window sashes have a 10mm cover to improve weathering protection and thermal efficiency thanks to the increased size of the glass area.
It all means double glazed units made from Optima systems achieve a 1.2 W/m2K U-value as standard, which guarantees that you meet building standards. When combined with soft coat glass, low iron, warm edge spacer bar and Argon gas fill, an Optima double glazed unit achieves an A+ rating. When using a triple-glazed unit filled with Argon gas U-values as low as 0.8 W/m2K and an Window Energy Rating of A++ can be achieved.
The depth of choice is impressive. Optima window systems have the widest choice of ancillaries on the market. You can also open up a world of colour with our beautiful colour foil options.
The durability and weathering protection are second to none. Optima window systems incorporate deeper drainage channels and have the benefit of faster water drainage. This not only means fewer service call-outs but reduces ongoing costs in the long term.
Security and strength are unsurpassed. Optima window systems feature a central Eurogroove to give the sashes greater rigidity. We have also implemented strategic local wall thickening for 35% better screw and hardware retention. Our secure bead system passes security tests without glazing clips and is ready for proposed enhancements to PAS24.
Design flexibility is assured. Optima window systems are designed to fully integrate with other Epwin Group products. Whatever the project, the products you use will suite perfectly and be fit for purpose.
Optima is a step-change in advanced window design for the 21st century. It’s why it’s the market leader. Choose Optima and it will change your expectations of what a modern window system should offer.
