Premium OW-80 Window

Our OW-80 window is the ideal installation if you want to allow more natural light into your home and enjoy a greater sense of space.

The aluminium structure weighs one-third of a steel equivalent and brings strength, durability and flexibility to your windows. Whatever your requirements and expectations are, we can meet and exceed them.




Why choose aluminium from Multifold Doors?

Aluminium is lightweight but extremely strong. It will not flex, warp, or corrode in hot or wet weather, unlike timber or uPVC. It is reliable, robust, and environmentally friendly; aluminium windows could even add to the value of your Buckinghamshire and Home Counties home.

Windows like the OW-80 are so low maintenance that all they require is the occasional wipe with soapy water.

Flush casement window

The OW-80 features an industry-leading internal and external flush casement. This sits perfectly in line with the frame to offer an elegant finish, both inside and outside.

Multifold Doors windows are stunningly designed and expertly made, as the high- quality aluminium we use gives you less window and more natural light.




Configured to your needs

The OW-80 is a totally bespoke window. Multifold Doors’s expert team will survey your property and ensure that the installation we create fits perfectly with your home and your vision for it.

Among the popular configurations in which the OW-80 are available are top hung, right hung, left hung, French windows and fixed frames.

High quality locking system

All Multifold Doors Windows by Origin are designed to offer the highest levels of security. The OW-80 uses top-quality handles, locking system and hinges to give you and your family complete peace of mind.

Even the hinge guards feature anti-slip and lock technology as standard, while all our window hardware is covered by our 20-year guarantee.




Your Colour

Multifold Doors windows by Origin 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.

This vast range of options ensures that, whatever your choice, you have artistic licence to come up with a colour scheme that is right for you.

Wide range of handles

It is reassuring to know that the handles of the OW-80 have been given the same level of attention as the frames and glass. This ensures they are the perfect finishing touch.

All Multifold Doors’s handles offer an elegant, stylish design that is a pleasure to look at and touch – and they can be colour-coordinated to match the frame.




Lower energy bills

Multifold Doors OW-80 windows, combined with a polyamide thermal break within the aluminium profile, not only meet thermal efficiency building regulations – they exceed them.

This ensures 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. Ideal for your Buckinghamshire and Home Counties home.
