"After seeing Channelglaze's full hopper thermal break windows at the Crick Boat Show, I knew right away my boat needed an upgrade — and I couldn't be happier with the decision. These windows are, hands down, the best I could have chosen. Compared to my old single-pane top hoppers, the difference is night and day: far better insulation, cooler in summer, excellent soundproofing, improved security, unbroken views, and premium aesthetics. I'm absolutely delighted with the investment, and my partner was so impressed, he upgraded all of his windows too. Channelglaze is a friendly, family-run business and it shows. Dave was incredibly helpful, answering all my questions and even resolving a minor issue with one of my portholes by designing and 3D-printing a custom component. That kind of service is rare. If you're looking for high-quality, thoughtfully designed boat windows — look no further!"

"Had a great experience with ChannelGlaze from start to finish. Dave P was very helpful over email at the design stage, patiently explaining all the options to me until I'd selected exactly what I needed. The windows were made on schedule and delivered on time. I've come back nearly a year later just to reiterate the same — it's important to know whether your window will last, and happily my windows (Thermal Break, full hopper, anodized frames) seem to be in just as good a condition as the day they went in. The difference it makes to the quality of life here on the narrowboat in winter is truly astonishing — I have no doubt I saved hundreds on heating costs this winter just gone. Highly recommended still, after a year."

"The single glazing and lack of thermal break window frames on my Sea Otter would unsurprisingly give the condensation problem. After many a conversation with Dave at Channelglaze, I decided on the full hoppers and portholes, double glazed and thermal break. Matt oversaw the measuring of the not so easy to measure arch windows and the subsequent fitting. I was pleased that the removal of the old, and fitting of the new, was achieved carefully without damage to the existing paintwork. They certainly look very smart and very well built and I am confident that all the benefits theories will be proven. I was very pleased and comfortable with all the exchanges with Channelglaze. My thanks to all concerned. Yes I recommend."

"Excellent service from Channelglaze. The new windows have transformed our narrowboat — warmer in winter, cooler in summer, and the build quality is superb. Dave and the team were a pleasure to deal with throughout. Highly recommended."

"First-class windows and first-class service. Channelglaze made the whole process easy from quote through to fitting. The thermal break windows have made a noticeable difference to the comfort on board."

"Great quality windows and a friendly, knowledgeable team. Would happily recommend Channelglaze to any boater looking to upgrade."

"Lovely family-run business with attention to detail. Our new windows look fantastic and the boat feels noticeably warmer. Thank you Channelglaze!"
