Flush aluminium casement windows

Origin windows

A wide choice of styles underpinned by exceptional performance. Origin aluminium windows by Cherwell Windows.

Origin windows offer two ranges in aluminium. A single and consistent focus on quality and performance.

We can offer you access to two distinct Origin aluminium window ranges: Origin OW80, Origin’s premium residential aluminium casement window range; and Origin OW70, Origin’s ultra slim sightline aluminium casement window.

The Origin OW-70 Aluminium Window

The Origin OW-70 window delivers ultra-slim sightlines of just 65mm, maximising the glass area.

It’s available as either an opening casement window, bay window or fixed-light, with either a contemporary square-edge or traditional chamfered/sloping bead to the double-glazed glass unit and a flush external finish between the opening sash, and the frame.

The Origin OW-80 Flush Aluminium Window

The Origin OW-80 window brings additional design flexibility to Origin’s energy efficient aluminium window range defined by an internal – as well as external – flush finish.

Available in standard casement, Origin french window, Bay window and Origin gable end window options, the use of a unique polyamide thermal break with Aerogel technology boosts thermal performance to the highest possible Window Energy Rating of A++ or a u-value (the measure of heat loss) of as low as 0.8W/m2K

It’s also ultra-secure and fully PAS24 tested. Origin OW-80 aluminium windows by Cherwell Windows also use Yale’s police-approved and Secured by Designed closer locking system.

Tested to 50,000 cycles, it’s made to last with a 20-year guarantee.

Origin Aluminium Slimline Windows

A perfect blend of visual style and energy efficiency with our Aluminium slimline windows. These windows are specially designed to seamlessly integrate ultra-slim sightlines with cutting-edge thermal performance. Crafted from premium-grade aluminium, our slimline windows not only enhance the appeal of your space but also elevate its energy efficiency.

Aluminium windows offer an unobstructed view of the outside world with their remarkably slim sightlines, creating a sense of openness and connection to the outdoors. Their technology ensures that your home remains comfortable year-round while reducing energy consumption. With no drafts or high utility bills, your space becomes comfortable while remaining environmentally responsible. Improve your living experience with Aluminium slimline windows, where aesthetics meet innovation.

Frequently Asked Questions

How energy efficiencient are origin windows?

Origin Windows achieve 0.9W/m²K with aerogel, 1.1w/m²K with triple glazing, 1.5W/m²K with double glazing. Origin Windows have an energy rating of A++. Therefore, Origin Windows exceed current building regulations by 0.1W/m²K with double glazing.

OW-70 offers the slimmest sightlines at just 65mm wide, ideal for those looking to maximise on natural light and views. OW-80 may not offer sightlines as slim as OW-70, however, it offers an internal flush casement, which OW-70 cannot provide.
