Security & Performance

High security comes as standard both in the design of the windows and the locking systems used.

The OW-80 window range feature the Encloser lock from the trusted and familiar Yale brand. This security lock offers the best levels of window security. Cylindrical cams engage into secure window keeps.

The OW-70 slimline window also has a multipoint lock from the quality Nemesis brand, offering secure locking points in all the critical window areas. Both windows come tested to PAS 24 security standards.

The window hinges also offer security at the hinge points of every opening window having built-in hinge guards. Also available are fire-escape hinges for first floor windows.

Energy efficiency is excellent with both windows exceeding the thermal requirements of current building Regulations. The OW-80 also comes with the Aerogel upgrade, offering even better thermal insulation and an A Window Rating.

Both Origin OW-70 and OW-80 windows come engineered for superior weather performance thanks to built-in seals and gaskets throughout the window.

Product Features


Both Origin OW-80 and OW-70 windows use crafted window components creating either a distinctive flush casement window or a modern casement window. Internally and externally flush casement.

The window hardware comprises window hinges of high-grade ferritic stainless steel, conforming to British Standards and having excellent corrosion resistance. Origin window hinges come cycle tested to 50,000 cycles and resist metal to metal also providing minimal wear. Added to this are hinge guards protecting prising the opening sash open from the outside.

The OW-80 uses the well-known Yale locking system having adjustable and bi-directional cams. These tighten and secure the window while keeping it neat and symmetrical within its frame. Window corners are double crimped for extra strength.

Restrictor hooks, trickle vents, fire-escape hinges are all additional components and hardware giving you added functionality, safety and security.


Origin windows come with energy-efficient units comprising a soft-coat low-emissivity coating, warm edge spacer bars and argon gas fill. We toughen this glass in your home where your new windows sit beside doors or at a low level.

Also available is laminated glass for enhanced security and forming part of many security tests. This glass holds together when broken thanks to a layer between each sheet of glass. So in the unlikely event of an intruder breaking the glass, they're unlikely to get through it.
