Information about Origin OW-70 Windows.

The Origin slimline window provides sight lines of 65mm wide, giving homeowners a window with thin aluminium profiles. As a result glass sizes are bigger with a less visible window frame.

Unlike the Origin Twin Flush, OW-80 Premium windows, the thinner Origin OW-70 Windows provide a different visual appearance, most noteworthy being no flush casement detail on the inside. Just like the entire Origin Home range of products, there is an industry-leading guarantee of up to 20 years.

Features and Benefits of Origin Slimline Windows.

The Origin OW-70 window is suitable for all types of old and new dwellings. Use this window to replace old timber, aluminium or PVCu windows.  It is also one of the most suitable windows for newly built window openings.  Therefore this window is comparable with all other windows on the market.

Slimline and Minimalist Aluminium Windows.

For homeowners wanting minimalist aluminium windows, Origin OW-70 is one of the thinnest.  When used with the standard outer frame you also benefit from a more discreet aesthetic than other windows on the market. Furthermore, this window is substantially slimmer than any PVCu or timber window.

Almost every version of this window offers a way to fit new contemporary windows, modernising the property as a result.

Flexible window styles.

Origin slimline windows come in several window versions. The benefit is a versatile and flexible window. Use this window either as a stand-alone product or to create combination glazing.

Sleek flush external finish

One of the unique features found in Origin aluminium windows is the flush casement. The flush casement means no overlapping frames on the outside, typical of most aluminium windows. This expertly designed feature means a more elegant, streamlined looking window, looking visually better than others.  Consequently, these windows work with old or new dwellings, cottages or townhouses and other property styles.

Furthermore, Origin windows come at bigger opening vent sizes than other brands. Top hung opening lights at sizes up to 1200mm wide and 1200mm high. Side hung windows at sizes up to 130omm high and 700mm wide.

Up-to-date window security and performance.

The OW-70 comes with insulated premium grade aluminium profiles. The benefit is a slim window with excellent durability, strength and quality.

Window security comprises a stainless steel multi-point lock with secure keeps. As a result, the windows engage securely in their locking points. Windows also come with bi-directional bolts. Window components include premium quality stainless steel, also extensively cycle tested. Window hinge guards, secure corner construction excellent joint sealing are other standard features.

Similarly, the window lock meets BS EN 1670:2007 Grade 4, measuring against corrosion and contaminants. Every window has excellent compression providing superior weather rating as a result. Finally, the Nemesis lock works with the locking window handles in a choice of styles.

Windows achieve the latest security ratings such as PAS24:2012.  Furthermore, they provide low U-Values, meeting current Building Regulations.

Origin Home products also provide a single point of guarantee. Finally there is the peace of mind of products available through a professional network of Origin installers all over the UK.

Comparing Origin OW-70 Slimline and OW-80 Windows.

Although both types of Origin aluminium windows have the key features and specifications Origin is well-known for, there are differences between the two. Overall, the key difference is how they look. The original OW-80 comes with more configurations options. The OW-70 is cheaper, slimmer and simpler to order, coming only as a fixed or casement window style.

I contacted Nick @ ATS for guidance on what aluminium sliding door systems would be suitable for an opening in an extension that is going to be both wide and tall. He came back really quickly with very detailed and incredibly helpful advice. He is clearly extremely knowledgeable about the systems on the market and their respective features and capabilities. If you’re feeling a bit lost by the overwhelming range of choices out there, I’d definitely recommend contacting him.

After a lot of research to find doors that would meet our unusual size requirements and feeling increasingly uncertain about the best way to spend our small budget, I stumbled on the ATS website, and I'm so glad I did! I contacted ATS to request advice and Nick promptly replied with a wealth of information, providing us with options and relevant contact details. I only wish I'd found them sooner!

I've been so confused about how to achieve the look I'm after, and going round in circles with various window/door companies, trying to get away from the huge chunks of plastic currently around my windows. I didn't expect an email to a company found through a Google search to really help - but I was desperate, so I tried. I'm SO glad I did. Finally I have clear explanations from ATS of where I've been going wrong, exactly what I'm looking for, and a list of local companies that might be able to provide it! The response has excelled my expectations and I feel as if I'm finally inching closer to a home with which I'll be happy and comfortable: thank you.

It is rare that I write reviews, however after my very positive communication with Nick - enquiring about suitable slim sash aluminium windows for my project, I felt that a review was definitely warranted. I can reinforce the many positive reviews posted so far, Nick was very quick to respond, providing comprehensive detail, with excellent independent advice.In summary, great service, thank you Nick.

I dropped Nick at Aluminium Trade Supply an email re high security slim sightline bi-folds and their alternatives and he responded that quickly (and so comprehensively) that I felt bad I’d not paid him for his time!Nick Sir your product knowledge is outstanding and you are providing a level of service that goes wayyyy above and beyond expectations. I’ll definitely make sure I mention Aluminium Trade Supply to anyone I encounter looking for a fenestration solution 🙏🏼

We are looking to replace some old UPVC patios doors with aluminium ones. The ATS website is a great source of advice in an area where clear information is sorely lacking. Having used the website, I then followed this up with a number of specific questions relating to our search, and Nick came back very quickly with clear, detailed and very useful advice.I have been very impressed with both the website and with Nick's advice. My only regret is that I didn't come across ATS before replacing various windows in 2021 - I'm sure it would have saved me a lot of grief and money! Thanks again Nick.

My experience with this firm was exceptionally good and this is notalways the case as a female, dipping a toe into technical waters.I was spoken too with courtesy and at a level that helped me consolidate what was needed .On top of that I was given a list of companies and places where I could obtain the type of product I needed.I could not thank them enough and would certainly go there again and reccommend others do too.
