This is our slimmest window yet. It combines strength with sleek design to deliver the finest aluminium window on the market today.
Available as either a casement or a fixed window, the OW-70 is ideal for spaces where it is important to maximise the size of the glass and the amount of light it allows in.
What’s your type?
Our OW-70 window, in contrast to the OW-80, offers the slimmest sightlines at just 65mm wide, making it ideal if you are looking to make the most of your natural light.
The windows are durable and low maintenance, and come with an industry-leading guarantee of up to 20 years.
Benefits of slim sightlines
The ultra-slim sightlines mean there is less frame and more natural light, allowing you to enjoy the view from your home while enjoying a truly modern appearance.
Despite the slimness of the sightlines, the OW-70 is available in sizes up to 4.8 square metres as either a casement or a fixed window.
Sleek, flush external finish
Whatever the style or age of your property, the OW-70 adds a touch of class and makes it a joy to look at as well as to use.
Our windows are expertly designed to feature no overlapping external frames. The Slimline Window will add a trim and elegant appearance to your home.
All of our orders are fully bespoke, ensuring you take delivery of a window that is perfect for your home – and that includes the handles.
The OW-70 comes with either an inline or crank handle. The choice is yours, but either will deliver a finish that fuses elegance and efficiency.
Origin windows can be manufactured in more than 150 RAL colours, so you will be able to choose the style that is right for you. If you choose one of our 11 most popular colours, we will be able to deliver them more quickly.
Should you prefer a traditional wood effect, our woodgrain options offer a wonderful authentic finish.
Configured your way
When you invest in an Origin window, you can be sure you will receive a creation that is truly engineered to your exact specifications.
The OW-70, available as a casement or fixed frame window, can be delivered in most sizes – and it comes with our industry-leading guarantee of up to 20 years.
Safe & Secure
Origin products use premium grade aluminium to deliver strength, durability and quality – and the OW-70 is no exception.
This window may be slim, but it is also strong. It has been tested to the highest standards and also features a stainless steel multi-point lock for extra security.
Our windows, combined with a polyamide thermal break within the aluminium profile, not only meet thermal efficiency building regulations – they exceed them.
Your home will be cool in summer and warm in winter, and as a bonus you will be able to look forward to reduced energy bills.
