Double Glazed Sash Windows

UPVC Sash Windows

Our UPVC sash windows provide all the character and appeal of traditional timber sash windows, but incorporate modern, up-to-date technology for outstanding performance with minimal maintenance.  When you’re replacing sash windows, we’ll provide a replacement window that’s just as handsome as your original window. Our double glazed sash windows are reliable and sturdy, and with gorgeous UPVC and wooden sash window frames, they’re sure to be ideal for your home.

Say Goodbye to Draughts and Noise

Brush gaskets eliminate draughts and noise, while the clever tilt mechanism on our sash windows allows you to clean the outside of the window from inside. When you buy box sash windows from us at Mark Robbins Improvements Ltd, we’ll fit the sash windows and sash window locks for you swiftly and without fuss. We pride ourselves on the reliable and professional service we provide for all of our customers, and we work with our customers to ensure that the windows they want are fitted swiftly and securely.
 
Our sash windows are manufactured locally in factories in Somerset. There is a range of finishes for these windows so that when they’re installed, they will be perfectly suited to your home. As well as a selection of beautiful finishes, there’s a choice of numerous decorative and practical glazing options that can be included in your window.
 
We use the very best hardware and top-of-the-range operating mechanisms which ensure smooth operation, and our mock horn and external Georgian bar options make our sash windows virtually indistinguishable from the timber sash windows they may be replacing.
