Introducing OS-44 / OS-77

A modern take on the traditional patio door, the Origin Patio Slider OS-44/OS-77 is the perfect fit for any type of home. Made completely bespoke, there are two sightline options available.

The OS-44 is the smaller of the two, with sightlines of just 44mm, maximising glass and the level of natural light which can flood in. With sightlines of 77mm, the OS-77 has slightly larger sightlines and brings a nod to the more traditional style of patio system, with an injection of effortless elegance.

The slimmest sightlines, more light

At 44mm and 77mm respectively, the two sightline options available on the Patio Slider OS-44/OS-77 are some of the smallest in the industry for this type of door – making it aesthetically stunning while flooding light into the home.

Glass options

When it comes to glass the Origin Patio Slider is completely bespoke, you are able to choose what type of glass works best for your space. This could be laminated, toughened or reflective, depending on your needs. No matter which you choose, you can rest assured that they have all been engineered to deliver the best levels of thermal efficiency, safety and security.

Up to 20 years

Origin pride themselves on providing meticulous attention to detail at every stage of the products’ design and manufacture, and oversee everything from their Buckinghamshire based factory. This allows them to offer an industry leading guarantee of up to 20 years on every part of the door which supports the panes – so the running gear, gaskets, frames, locks, levers and seals.

Thermal efficiency

Whether it’s for a new build or a retro fit, both the OS-44 and OS-77 beat British Building Regulation requirements for thermal efficiency. The systems are thermally broken and made with a polyamide thermal break, meaning heat loss is drastically reduced and the temperature is regulated, so the space can be enjoyed all year round. Both systems deliver a U-Value of 1.2 for triple glazing and 1.8 for double glazing.

Stunning and secure

Toughened glass combined with premium billets of aluminium makes for an incredibly strong Patio Slider system, and the OS-77 takes this even further by conforming to the strict security standards of PAS 24:2016. No matter which handle and lock configuration you choose, you can be assured that testing has taken place on all of our barrels to ensure they are resistant to common breaking and entry techniques such as drilling, picking, snapping and bumping.

Bespoke to your needs

Available in up to three door sets, the patio slider OS-44 and OS-77 can be made to measure in a space as small as 1.8m and as large as 11.8m. You can choose whether you have all doors sliding or one fixed, depending on your needs. It really is a door system, made for you.

The Patio Slider OS-44 and OS-77 features a stainless steel finish handle which can be operated from both the inside and the outside, with some options on the way that they work.
