Sash Windows


Our bespoke sash windows maintain the old craftsmanship beauty while using modern day technology. These windows are perfect for your traditional properties where you want to maintain the looks but higher security, soundproofing and energy saving to your home. All our windows come in standard as double glazed with a slim double-glazing option possible where you minimise the thickness of the glass for a cleaner look while maintaining good energy efficiency results. All sash windows are open by sliding either upward or downward. This makes it extremely functional as it doesn’t take up a lot of space compared to a casement window which opens inwards or outwards.

Types of Sash Windows

There are two types of sash windows, balance and counter balance which are systems that use springs or weights respectively. The counter balance tend to have a more traditional look due to the visible rope and pulley that mechanise the window. This tends to result in a thicker frame compared to the balance sash windows as the mechanism takes up more space. On the other hand, balance windows are operated by a spring system that is hidden inside the sash frame and as it takes up a smaller amount of space. This results in the frame being thinner, giving you a wider area of natural light entering your property.
