uPVC Sliding Sash Windows

First created in the 18th century, wooden sash windows were once considered something of a status symbol on properties of the era, offering, as they did a better alternative to the windows of the day. However, their design and manufacture in softwood with old fashioned paint treatments leaves them susceptible to wood rot, issues with the weights and panes causing the windows to stick or rattle and they require considerable ongoing maintenance. 

Heritage Vertical Sliding windows provide a modern alternative to outdated sash windows and are perfect for period properties and houses within conservation areas which require the more traditional look. 

The Heritage Rose window has a slim profile maintaining many of the original design features typically found on timber sash windows, such as a deep bottom rail, run-through sash-horns and authentic external putty lines. However, the windows are built from long-lasting uPVC available either in white or in a choice of wood-grain foils giving the look of timber, but with none of the maintenance requirements, all they need is a quick wipe down to keep them looking as good as new!
