Frequently Asked Questions
What is a sliding sash window?
Sometimes referred to as box-sash or vertical slider and is usually made up of two large panels (called sashes). Depending on the design style, one of the sashes will usually slide past the other, but some sliding sash windows allow both sashes to slide.
They’re a good option for decks and patios where an outward-opening sash would get int the way or for bathrooms and windows around the side of the house. Their neat, minimalist look paired with easy-to-use functionality makes them a popular option for homes in the UK.
The two main types of sliding sash windows are horizontal sliders (which slide from side to side) and vertical sliders (which slide up and down).

How do they work?
Vertical sliding sash windows are made up of two sashes that slide up and down, and the sashes will usually be the same size. To ensure that the sash remains in place after you slide it up, the sash contains a counter-balance mechanism to keep it in place, without the need for sash weights, cords or pulleys.
Horizontal sliding sash windows are mounted in such a way as to slide past each other horizontally. They can be single sliders, where either the right sash or the left sash can move, or double sliders where both sashes can move.
How long do uPVC sash windows last?
uPVC sliding sash windows are designed to last for decades, even in more extreme weather conditions such as coastal regions. Sliding sash windows that have been professionally installed, well looked after and not subject to extreme weather can be expected to have a lifetime of thirty years or more.
Are sash windows safe?
uPVC sliding sash windows are designed with your security in mind. You can specify the locking mechanisms with our comprehensive range of security upgrades, making them a safe, secure sliding sash window choice.
Are timber or uPVC sliding sash windows better?
With the benefits of modern manufacturing, uPVC is considered the better option as they are more durable, require very little maintenance and have a much lower price point. Wooden sliding sash windows, in comparison, need frequent attention, are liable to rot and peel over time, and have a much shorter lifespan even if they are well cared for.
