Add period charm to your home with sash windows

Our vertical sliding windows are the perfect replacements for those used in Victorian and other period style properties. Although, it is common for them to be seen in new builds and traditional red brick houses too. Here at T&K Home Improvements, our vertical sliders are available in 2 different materials: uPVC and timber. However, they can also be customised with a range of authentic sash window furniture, numerous colours and more.

Low maintenance uPVC sash windows in Luton, St Albans, Cambridge and Bedford

Although uPVC is not the traditional material used to build vertical sliders, ours are strictly built with original sash window design in mind. So, you can still enjoy an authentic appearance. Combining the natural insulation qualities of uPVC with draft-excluding wool pile and seals, they keep in the heat and keep out the draughts too. Therefore, leading to a comfortable home.

Even though uPVC is super easy to clean already, it is even easier to clean our uPVC vertical sliders because the window sashes can be tilted inwards, allowing you to clean them from inside the home. They also feature locking cam catches and a reinforced meeting rail, so they do not compromise home security either.

Therefore, you can enjoy quiet and warmth throughout the year.

How to secure sash windows?

Sash windows come with their own distinctive selection of hardware, which helps to keep the home secure from forced entry attempts. This includes:

• Reinforced meeting rails – this is the top rail of the bottom window sash and bottom rail of the top window sash.
• Sash fasteners – these secure the 2 window sashes together.
• Sash stops – these work by preventing the window from being fully opened.
