Double Glazing
Our double glazing solutions enhance thermal efficiency and reduce noise pollution. Using advanced units filled with insulating gas, we help homeowners lower energy bills while maintaining aesthetic appeal. Available in uPVC, aluminium, and heritage designs, installations meet current building regulations and come with long-term warranties.

Projects include structural support, roof replacements, and custom glazing options to maximise natural light and energy efficiency.

This is third time I've used Novaglass because they are excellent. Professional and knowledgeable about their products; superb quality of workmanship; excellent quality finish and very reasonably priced. This time they've installed a new front door and bay window - which have significantly improved the exterior of my new home. I chose the door design I wanted and they sourced the door for me. I would highly recommend them to anyone keen to install new double glazing windows/composite front door.

Would recommend Novaglass highly. I recently purchased a set of French Doors and windows from them and am delighted with all aspects of the quality & installation. Delivery was as agreed & the fitters were efficient & polite. Good communication throughout, very helpful and a professional finish.

We had aluminium windows fitted across the front and pvc across the back all completed in three days as per schedule. Professional service with a very well organised team providing a very high quality product. Would definitely recommend them.
