Sash windows from Global Windows are sure to complement your Sheffield home, regardless of whether it's a modern or period property. If your Sheffield home is in need of ventilation, our sash windows excel in this thanks to the vertical sash system allowing for a wide opening.

Modern performance and traditional aesthetics for your Sheffield home

Featuring all of the original features such as astragal bars, sash horns, and traditional style hardware, our sash windows are able to retain your Sheffield home’s traditional character whilst bringing the advantages of 21st-century technology. Our sash horns faithfully replicate the traditional period aesthetic whilst still being decorative. To separate the glazed sections, we utilise the Georgian bars. To create a realistic replication, these external Georgian bars are attached to the exterior of the window pane. The ‘A’ rated sealed glazed units filled with argon gas allow modern benefits to work alongside the period aesthetic.

Sash window features and finishes

Your choice in finish can change the entire visual appearance of your sash window. Give them a natural finish with a wide range of realistic wood grain effect coatings, or replicate the original look with white or cream colour options.

Beyond your choice of frame, we have plenty of options when it comes to glass. There are popular options like clear glass, as well as more niche choices such as toughened safety glass and obscure glass, which allows for more privacy.
