We've been using Granada Glazing products for about 4 years now on all of our secondary glazing installs (City Insulation Ltd). The range of styles is excellent so they discreetly match primary windows and the effectiveness at reducing external noise pollution is fantastic. Our customers are amazed at the level of noise reduction achieved, not to mention increased warmth within their homes which is so important as energy bills are rising at such rates. We wouldn't use anyone else!

We have used Granada Secondary Glazing as our supplier for over 10 years. The service and product has always been of a high standard which we are extremely pleased with and so are our customers. Delivery has always been on time and the price is very reasonable. We have used their products for both Domestic and Commercial contracts. Their technical help is fantastic too. I am sure we will continue business for many more years. Hadrian Window Systems Ltd

We've been using Granada for a few years now and really can't complain about anything. They deliver when they say they will and they are always helpful with technical info and advice for surveys etc. The product is top quality but they are always looking to make improvements to make it even better. We would certainly recommend them.

We've just had some secondary glazing installed by Granada Secondary Glazing and the results are far better than we could have ever imagined. The whole team were fantastic, professional, courteous and efficient and I'd highly recommend them to anyone looking to get secondary glazing installed. The difference in sound and heat insulation is already obvious and the quality of the installation is evident. Highly recommend!

We have purchased secondary glazing hinged frames from this company before and they were the best we have installed the customer was delighted it was a quality product. We purchased another 2 for the same customer but Granada has changed the hinged units, the 2 we received were so cheap and nasty looking i don't think they are fit for purpose. A flap for a handle no espag handle or lock to keep it tight to the frame to cut out the noise what secondary glazing is suppose to do

Granada Glazing produces an excellent secondary glazing system, which is not only highly effective in reducing external noise, it also keeps the heat in and draughts out. The secondary glazing panels are really good quality and have slim frames, so once fitted, they are virtually invisible. They offer a professional service and I would certainly recommend the company.

We have had the pleasure of working with the team at Granada on multiple occasions, providing a variety of Video Production Services, from Case-Study Testimonials, Installation Videos and Promotional Content. When shooting on location to editing the projects in post-production, our collaboration with Granada has been a hugely positive experience. From the testimonial projects we have been involved with, we can clearly see the quality of the products and customer service shine through after hearing it directly from genuine customers. We look forward to continuing our fantastic working partnership with Granada.

Placed an order on the basis that the units would take 2-3 weeks to be delivered, they took four weeks and when they did arrive some of the units were the wrong size! Due to the mistakes of Granada our company lost a project and refused to refund us for the order and tried blaming us. Terrible company with no complaints procedure and poor attitude towards paying customers.
