ALUMINIUM CASEMENT WINDOWS ACROSS SOUTH YORKSHIRE

At Global Windows, we install both OW-70 Slimline and OW-8- Premium ranges, aluminium casement windows that combine traditional design, advanced manufacturing, and versatile premium grade aluminium for high levels of security and thermal efficiency to complement any kind of property.

The OW-70 Slimline window range offers more natural light thanks to a super slim sightline – if you’re looking for more customisation and configurations, then we recommend the OW-80 Premium range.

For an added touch of classic yet contemporary elegance, we offer the option of adding Georgian bars to your casement windows. Right on trend, this style is often referred to as a steel look, and can be styled however you choose – horizontally, vertically, or both, based on your preference.

    VERSATILE WINDOW OPTION

    THE BENEFITS OF ALUMINIUM CASEMENT WINDOWS

    The subtle strength of aluminium provides your home with warmth and security, while supporting the current popular designs of vast window spaces. Using 28mm sealed units and polyamide thermal break technology, we ensure that all our windows conform to the Building Regulation requirements. Not only does this make for a highly contemporary looking window, but one that is equally at home in both older and traditional properties.

    Our contemporary aluminium windows are available in bespoke designs and sizes to meet any customer specifications. All our casement windows are double glazed and the glazing is internally beaded for extra security. With this window design from Global Windows, your home will be lighter, brighter, and noticeably more energy efficient.

    Windows & Doors

    Brilliant company from all we’ve dealt with, right through to the fitters, to the follow-up emails making sure everything was ok. Having used you before and after having work done to my property, I thought you the only obvious choice to return. Was a little worried as I’d had insulated render fitted and was concerned about the removal and refitting into the same size opening, and the damage it would cause. No worries, it seems. Each to their own trade as they say, and I’m glad they managed it and left me in no doubt, another great job done. Many thanks to you all. And see you in 15 years again?

    Windows And Door

    After a fair few months of looking for a good window provider we can say we are one hundred percent happy with Global. They exceeded our expectations from start to finish. Michael with the quote, the lovely ladies from the office and Andy and Josh who fitted our seven windows and front door. Very professional, good quality, quick and efficient work. A pleasure to work with such a team. Our next step is the conservatory with Global. Thank you and well done to all.

    Excellent Service

    My mum wanted to say thank you so much for the fantastic service Global windows have given her following her burglary. From start to finish they reassured her the replacement patio doors would be robust and fitted as quickly as possible to ensure the property was secured. On the day of fitting the fitters arrived promptly and installed the doors with no mess. The gentleman who organised this from Global (sorry she couldn’t remember his name) came out to check the doors and to see mum was happy with them brought her a beautiful bunch of flowers. Mum was over the moon. Thank you so much.

    Doors And Windows

    We decided to re-use this Company despite moving house and County. Global were helpful and very professional at all stages of the installation. We found all their staff friendly and knowledgeable. Dates given, returning phone calls etc. were all met. The price was very competitive, the quality of their products was excellent with a good range of colours and styles. The fitters were very hardworking, managed to get the work done in one day rather than the expected 2, mainly due to the fact they worked as a team, didn’t take breaks and clearly knew their job. Great company.
