uPVC Vertical Sliding Sash Windows


Vertical sliding sash windows are the ideal choice for maintaining the period look of a heritage property. However, they are equally at home in a modern setting as well. In fact, uPVC vertical sliding sash windows are a great way to add modern functionality with a traditional look.

How does that work?

uPVC windows offer the clean and classic wooden joinery look because of their chamfered profile. This, combined with a wood finish, gives you windows that look just like authentic wooden windows.

However, the uPVC chamfered profile of these vertical sliding sash windows also makes them great at retaining heat. Additionally, all are installed with seals and insulation, making them much more weatherproof than their traditional counterparts.

Because they open by sliding up, these windows are also quite suited for houses where opening space might be a problem. They don’t require a swinging space, which leads to optimum space utilisation. What’s more, the superior quality of our accredited suppliers gives you smoother sliding action for years.

Optional Sash Horns

Sash horns were added to heritage sliding sash windows to provide strength and support. These aren’t needed now, but they add an authentic look to your vertical sliding sash windows. This is why we include optional sash horns in our price comparison to give you the right appearance for your heritage property.

Spring Balance Mechanism

Instead of using the old-fashioned weights and pulley system, uPVC vertical sliding sash windows use the modern spring balance mechanism. As a result, these windows operate much more smoothly, without any visible and unsightly gearing.

Concealed Gaskets

Unlike the old, leaky, draught-prone windows, uPVC vertical sliding sash windows are better at weatherproofing your home. They are equipped with concealed gaskets that effectively seal your home from the unpredictable British weather and noise.

Safety Restrictors

If you have children in your home, you don’t want windows sliding down and trapping their little fingers! This is why many suppliers offer you optional safety restrictors. These safety restrictors don’t allow the window sash to slide down fully. As a result, little fingers and even paws are safe from injuries.

Enhanced Security

All windows offered by our accredited suppliers come with the option of extra security features in addition to the default ones that come with them anyway. In fact, our suppliers have security options especially designed for vertical sliding sash windows. As a result, you can upgrade your windows to get improved security.

Tilt Operation

Traditionally, sliding sash windows have been notoriously difficult to clean. This is especially true for the outside panes. However, we allow for optional tilt operation to be included in your deal during our price comparison process. This allows your windows to tilt in like tilt and turn windows for easy cleaning of both inside and outside panes.

Vertical Sliding Sash Windows

uPVC vertical sliding sash windows offer numerous advantages that traditional windows don’t. These include weatherproofing, insulation, and enhanced security.

We have a colour selection ranging from traditional to modern colours. If you have a heritage property, you have a selection of wood finishes to choose from, including Golden oak and Cedarwood.

Wood needs regular sanding and polishing as the colour fades, or peels and flakes when exposed to the elements.

Unlike wooden vertical sliding sash windows, uPVC windows are exceptionally easy to maintain. All you need to do is wipe them down with a wet cloth.
