No home is the same, each having its own unique character. Why should your windows be any different? Our casement windows are made bespoke to suit your needs.
Choose from either the slimline OW-70 or premium OW-80 system.
Choose how your windows open and the direction they fold in.
Choose from a selection of stunningly designed handles from our ranges.Our Casement windows can feature left, right or top openers, and can be specified as a side hung, top hung or dummy sash – or a combination of all of these to suit your needs and your windows' desired function.
Because everything we do is bespoke, we can manufacture your window in a configuration that works for your home. This can include a combination of different openers and fixed frames, and thanks to an ultra-slim aluminium profile, the OW-70 can offer the some of the slimmest yet most energy efficient windows on the market today, so you can be assured of the best view of the world outside your window.
For an added touch of classic yet contemporary elegance, we offer the option of adding Georgian bars to your Casement windows. Right on trend, this style is often referred to as a steel look, and can be styled however you choose – horizontally, vertically, or both, based on your preference.
A truly unique window with an industry-first internal and external flush casement, the OW-80 Casement Window will not disappoint.
Completely bespoke, OW-80 casement windows can be manufactured in a huge array of configurations. With large maximum sizes, it also offers the option to couple windows next to each other to ensure that we have a window solution for any size aperture. Individual side hung casement windows on the OW-80 can be made up to 1,800mm in height by 1,000mm wide.
Whether a premium metallic or one of Origin's industry-unique colour-coordinated options, you can be sure of a contemporary handle which offers the same faultless performance as the window itself – and you can colour-code the gaskets to match.

Maximum dimensions of 1,400mm in height and 950mm in width on the side hung window.
Like the window, the handles are made from aluminium, but also feature a Hardex Electro finish for complete durability. Therefore, with the OW-70, you're guaranteed a handle that offers flawless operation, outstanding quality and an exceptional finish. For a colourcoded finish, our offset handle (used on the OW-80) can help create a unique look.
