Effortless sliding action for generous light entry and ventilation

Sash windows are known for their unique ability of letting their sash to slide upwards into the frame, allowing homes to enjoy a better sense of the open feel of nature. If ever you’ve previously failed to fully enjoy the natural light and air the outside has to offer, sliding sash windows from Jack of Glass offer you the best of both worlds, being great in design as well as function.

As well as letting in an appreciated cool breeze, uPVC sash windows from Jack of Glass are capable of delivering impressive levels of heat retention and thermal efficiency. Boasting an inventive multi-chambered design means that any heat generated in your home have a tougher time escaping from your property, unless of course you wish to slide open your new sash windows and enjoy the natural open air. Warm or cool, you have complete control.

A traditional design with modern ease of use

Although inherently classic in terms of aesthetic design, our range of uPVC sash windows have successfully evolved with the times, catering to the specific needs of the modern homeowner. For increased child-safety and effortless cleaning for example, each sliding sash boast an easy-clean tilt feature which allows the window to be tilted towards the user, meaning they can be cleaned without ever leaving the comfort of your own home.

Once installed, you’ll be able to enjoy a low-maintenance, rattle-free and modern constructed sliding sash window that never fail to deliver eye-catching visuals and impressive year round performance.

We have recently had our front door and windows replaced by Jack of Glass. They were great. The communication was amazing, we knew every step of the way what was happening and they left place spotless. Our new door and windows have completely changed the house.

Jack of glass have recently replaced all my windows efficiently and to a high standard. The price was also very reasonable. The customer service was outstanding along with the services they provide. Highly recommended.

Mr Bennett

I had to replace a small double glazed panel in a window. I though it would be difficult to get anybody interested as it was such a small job. However, Jack of Glass did the work. They visited the house to take the measurements, ordered the replacement glass and fitted it all very efficiently and at a reasonable cost. I will use them again.
