uPVC Sliding sash windows in Sheffield infuse traditional aesthetics

Our uPVC sliding sash windows deliver the perfect way to retain your home’s traditional character with all the advantages of 21st-century technology. Comfortably replacing a wide range of vertical sliders with ease, our expertise stretches to splay, box bay, arched and swept head sliding sash windows.

Delivering all the original features, including astragal bars, sash horns, and traditional style hardware, sash horns were originally used to support the glazed panels. Our sash horns, although decorative, faithfully replicate the traditional period aesthetic. Georgian bars were also used to separate the glazed sections. Our external Georgian bars are attached to the exterior of the windowpane to create a realistic interpretation. Alongside the period detail, they are glazed with argon gas filled ‘A’ rated sealed units for the ultimate thermal efficiency.

Sash window finishes and features

Replicate the look of timber box sash windows with your choice of finish, whilst tastefully reproducing the original look with white or cream. Or for a more natural finish, we have a range of realistic woodgrain effect coatings which are durable, attractive, and easy to maintain.

Alongside your choice of frame colour and style, the type of glass you choose can make a huge difference to the overall look of your sash windows. Clear glass is the most popular choice, but if you want something a bit different, at Global Windows we have a range of glazing options. Choose from our selection of obscure glass for extra privacy or, if safety is your main concern, opt for toughened safety glass.

    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.

    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.
