A design we pride ourselves on, Channelglaze arched top windows are the most elegant and desirable windows for use on Dutch barges and wide beam boats. In addition to the Bottom Hopper there are other opening options available within our arched top range and for an extra charge we offer a Make To Template service wherever possible or can supply templates and/or drawings of our standard arched dimensions.
Relatively new on the inland waterways, they became popular with the trend for Dutch barge conversions. Many such boats are a source of great pride to the owners, and to this end we offer the highest quality arched top windows available.
The Bottom Hopper is a very high-quality, functional window and is classed as our standard opening type for the arched top range in both double and single glazed options. The fundamental differences between the Bottom Hopper and its Top Hopper counterpart, lie in the location of the 4mm toughened hopper pane on the Bottom Hopper: at the lower section of the window rather than the upper. Utilising a 4mm toughend fixed pane above the hopper, both panes are separated by a horizontal central bar.
The size of the drop back vent on the single glazed Bottom Hopper is approximately 12” high (15” on 24” high windows). It can be removed for storage to allow for extra ventilation. An aluminium top glass bead is fitted across the top of the 4mm toughened hopper glass and tilts inward on release to rest on a pair of roller arms. High-quality, durable, easy to operate sash locks are located on the top glass bead and their respective keeps are located on the main frame of the window, which hold the hopper in a locked position.
Located around the perimeter of the opening section on the main frame of the window is a neoprene foam weather seal, which provides a solid barrier against air infiltration and water penetration and significantly reduces noise transmission. Attached to the main frame is our rubber flipper gasket, located along the bottom edge of the opening, which the hopper pane sits on. The fixed panes of glass fit into the frame of the window by utilising an odd leg gasket or wet sealed, depending on options and application.
Condensation channels are built into the main frame of the window with drainage slots to the outside. These are protected from the elements by an aluminium drainage cover.
As with all windows across the Channelglaze range this design is custom made to fit your aperture.
Thank you so much for the efforts that you and your team have gone to in order to sort out my window. They are very much appreciated.
David Bennett
We are delighted with our new windows and are currently attempting to persuade another boat owner on our mooring to purchase from you.
David & Maureen Titchener NB “FINGOLFIN”
Please convey on my thanks to [your fitting team] for doing such a good job of fitting the windows in NAIAD.
Chris Agar NB "NAIAD"
I’d like to say the biggest thank you for our windows, they were so easy to fit and look better than we had ever imagined... I wrote a sign and put it in the window, telling everyone who read it how good you were.... we are back where we belong and its all thanks to people like you... without you we would have given up and for that we thank you from the bottom of our hearts. We will never forget you and your kindness.
David & Julie (and Milo) NB “EM II”
It has been just over a week since my new windows were fitted and I am thrilled with them. I want to say a big thanks to you and everyone in your team involved in the organising, making and fitting of them. It has been a very efficient process all round and Channelglaze has lived up to its reputation for quality and good service.
Alison French NB "Mayer"
Many thanks, excellent service, very impressed and I would highly recommend.
John Sealy
I would like to pass on our sincere thanks and appreciation of your company’s fast and efficient repair of my narrow-boat’s 20 year old double glazed window. The repaired window is now re-fitted and all within a week of its removal. It is really reassuring to know that there are still companies out there such as Channelglaze who really do care for their customers.
Tim Wooding
Thank you so much for your help yesterday and showing us round your factory. We have decided to use your company for our windows. We look forward to hearing from you in due course.
Gloria & Derek Phillips
All our double units are now fitted. Thank you again for all your help and encouragement. It was an absolute pleasure to meet you all and we look forward to a warm and cosy winter later in the year. But before then we have some serious cruising to do.
Peter Thornton
I felt I must write to you about my windows you manufactured for me over 8 years ago. They have been a great success, far beyond my expectations. Even after more than 8 years of the gruelling use of a "Liveaboard" boat, the windows are in almost showroom condition today... It has been solely due to the high standard of materials, workmanship and the personal pride of every single operative in your factory, during the manufacture all those years ago. I am so glad, that after seeing other manufacturers, I decided that you were my choice of company. I was looking for a well-made window, with lasting qualities... Your staff were interested in giving me exactly what I wanted, and after visiting [your factory] a couple of times, you gave me the confidence to place my order with you. A big, big, BIG, Thank You! For your personal service and outstanding window design and manufacture.
Allan Cazaly NB "PENGALANTY"
A belated message to thank you all for the excellent service while providing our new boat windows. We are at present sat here in a howling gale and pouring rain, completely snug and dry and couldn't be happier. We are still trying to get used to getting up in the mornings and not having to wipe condensation from the glass, the windows are all you promised.
John & Diane Finlayson NB "Our One"
I just had to write to you to say what superb windows you manufacture! I don't think I'll ever be forgotten as a customer, because I was so fastidious to achieve perfection in quality and the exact colour red I wanted. [Channelglaze] excelled itself and over-delivered! I have never seen windows as perfect as mine... Now there's a compliment for you! The statement is true and I am so pleased and grateful that I decided to give my order to you company all those years ago.
We are really pleased with the windows and it was amazing to watch the lads at work. We couldn’t believe how quickly the old windows came out and the new windows went in... As the weather has been so warm since the new windows have been fitted we don’t know what the insulation benefits will be yet. However, they are definitely more soundproof. We are very pleased and very impressed.
Jackie & Ted Vowles NB "The Answer"
The fitting went well. Very professional job that we beat the worst of what turned into torrential rain that has lasted all night. However, the upside is that I know for sure that at this stage there are no leaks.
Terence Simmons
Whilst on the subject of windows, I would just like to say how pleased I am that I have your double-glazed units throughout my boat, which enables me to lead a warm and comfortable life in the wintertime. The company, who built my boat, entered it in a competition run by the I.W.A in 1992, the year it was commissioned. The builder had taken a lot of trouble to use only the best materials for the boat and I have benefited from his choices. The windows have retained their looks, strength and shape since that time. Thank you for your kind help in the past and more recently.
Lynne Leys Richardson
We thought it was about time to write to you to thank you for your excellent service in providing us with the windows for our boat. The double glazing works exceptionally well in reducing condensation and noise reduction (we moor under the flight paths for East Midlands Airport!). Once again thank you for your service and hospitality you showed on our visit to the factory.
David & Catherine Waters NB “Baloo”
The pictures don’t do them justice… They improve the looks of a boat and not to mention the dreaded condensation! I am really pleased with them, well worth the money. Thank you for your service and we both wish yourselves and the company's future success.
Su & John Mills NB “APRIL LADY”
The canal cruising season is here again and our boat “Muskrat” looks very smart with the new windows your people installed so quickly on a short winter day last December. It’s wonderful to have no leaks anymore and the cabin is noticeably warmer on chilly evenings. The boat looks years younger and has been much admired. We certainly recommend your windows to all the boaters we meet. Best wishes and thanks
Torence Boughton NB “MUSKRAT”
Forget Me Not, our narrow boat, is now back on her mooring. Friends who know her, or thought they did, have been suggesting a new boat is on our mooring. She looks lovely, just like a new craft. Thank you not just for making the windows for us, but the speedy turnaround. You certainly put my mind at ease, when things had to be done so quickly.
Paul & Ursula NB "Forget Me Not"
I inspected the trims and the windows last night. I am delighted with the end result. I would like to thank you all for being thorough and addressing the problems we had. Thank you to Matthew for his excellent work and dedication to getting it right so as to make us happy; which he well and truly did. I will enjoy showing my fellow boaters the new windows and trims and will have no problem recommending your windows in the future. May I wish your business great success and thank you for your excellent windows.
Jason Richards NB "Emma"
I just had to thank you for such amazing service. We will certainly ensure that the efforts you team have gone to, will be announced to the canal boating fraternity via our website and hopefully the guys at Saltisford.
Martin Lawson The Swift Organisation
Just a short note to thank you and to say how pleased everybody is with our double glazing. We have only recently been on Phoenix since the job has been done and, as a result, canvassed everybody for some feed-back which, I have to say, has been outstanding. If, in any way, we can be of assistance in driving your company forward - please do not hesitate to ask.
Alan Longhurst
Just to say [a member of your team] was asking today if we’d been pleased with the windows and if we thought it worth the extra for [Channelglaze] double glazing and the answer is, absolutely, without a doubt. It’s one of the things we regularly say was worth it. Fantastic all through last winter when we were iced in for 8 weeks... of course, we’re not foolish enough to think there will never be any condensation – but it was minuscule. Our last boat was a nightmare.
Jan Swatridge NB "QISMA"
Just a thank you for completing my order within the estimated time. My wife has seen and approved so I will not ask the lads to put the old ones back!!! The windows are very smart and done much to improve the appearance of the boat. Thanks to the lads who did a good job fitting them.
Pat & Shirley Mason
With regard to the quality of the Channelglaze windows, we are very pleased with them and their energy saving advantages. We would also hope that you have had further enquiries from [our boat builder], as they are a quality item that befits his boats. Thanks again for your reply and advice.
Mike Christian
The new windows look absolutely fabulous with the frame colour being absolutely perfect against the deep maroon of the cabin side. I'd like to thank all of you for your co-operation and patience in producing these windows... it really was worth it in the end! The whole process was truly a family effort; we are still admiring the end results and would recommend your services to anyone seeking to replace their windows.
Derek Vale NB "Rosan"
Nice to know there are some companies that know what 'customer service' means. That is why we chose Channelglaze at Crick. The other window companies answer to any questions was 'take a leaflet'. Your people answered all questions politely and helpfully. They were interested in our potential order without pressure selling. Pleasure to do business with.
Peter Kirchoff
Just to thank you very much for sending a replacement window rubber for our boat. It is now installed and fits perfectly. As mentioned previously, we are very pleased with our windows (barge type, with cream powder colour, supplied in 2001), and they have been much admired by other boaters.
M. Maynard
I would like to confirm that the window liners are just perfect. John is a very happy bunny now and we shall be pleased to tell other boaters that they were provided by Channelglaze. Thank you very much for your help and co-operation.
Chris Bowyer NB "Plover"
We think [the windows] look very nice and we have had many compliments on them.
Richard Shields & Kathy Williams NB "Le Premier"
We had our windows supplied, for our boat builder to fit in 1996, and wouldn’t have hesitation in recommending Channelglaze windows to fellow boaters, boat builders and others. The glass was coated with a treatment that allowed rain to run off without marking or smearing, and we would confirm that it has worked effectively for the past thirteen years. Therefore we would be very pleased to allow interested customers to view our windows by arrangement with [your team] at Channelglaze.
Mike & Sue Turner NB "Shotterybelle"
We completed our fit out last June and launched the boat at King’s Lynn docks. She is moored at Denver Sluice on the River Great Ouse. We leave next week for a four month exploration of all the northern waterways. Your windows have already been much admired. We hope that business is going well.
Andrew & Sally Rawnsley NB “The Puzzler”
The delivery date was as originally promised, and the standard of fitting, attitude of your fitters was excellent. We are more than happy with the finished result. The windows are well made, well finished and expertly fitted. This has made our boat now look stunning. We would have no hesitation in recommending your company to any other boaters out there, who are looking for a company that believes and practices in customer service and satisfaction.
Rob & Sue Kealey NB "Tangled Up In Blue"
You will recall our order for 11 large windows at the end of last year. I am pleased to say that they look great, we have completed the installation of the frames and will be inserting the trims this week.
Rob Shackleford
Have just returned after 3 weeks out on “Jenanme” – not a drip from the hatches! Many, many thanks for all your efforts.
Mick & Jenny Hill NB “JENANME”
I just wanted to say thank you and your team for a wonderful job you completed on my N/B "Callisto" earlier this month. The windows are of high quality and the fitting has been first class. The result has truly transformed my boat and will beneficial for my future comfort when I am 'on tour' of the UK canal network.
Ian Drinkwater NB "Callisto"
We would like to thank you for your excellent service and care in the provision and fitting of replacement windows to our 55ft narrow boat ADAGIO. We spent some time looking at various potential suppliers and were pleased with your prompt response. We made a request to visit your works where we were given a no pressure explanation of the various styles and features of you range. We received excellent value for money and have no hesitation in recommending Channelglaze to any who might ask.
Roger & Jean Evans NB "ADAGIO"
Just to let you know how I’ve got on with the double glazed windows you supplied for my narrowboat. Once again thanks for doing this in double quick time. The windows have been excellent, warm in winter, cool in summer, just what I wanted from double glazed units. The sound dampening is great too.
Craig Marshall
Thank you so much for your help and excellent service in getting the replacement window to us so quickly. The windows are always admired and we will continue to recommend you and your excellent service to those who ask. We have just returned from 3 weeks away on the Canal du Centre and the river Saone temperature of 44 [degrees Celsius]!! Thank you once again.
