Channel Glaze - Narrowboat Windows


Frame Options


Narrow Boat, Canal Boat, Barge, Dutch Barge – Whether Your Pride and Joy, Channelglaze has Frames for you!

Channelglaze Ltd offers a wide range of marine window frame options in both single and double glazed glass. These frames range from face-fixed to clamp-in and are manufactured in aluminium. We are continuously developing new profiles and gaskets for use with our applications and designs.

When ordering windows from Channelglaze Ltd, notes should be taken on a few technical details, in order to ensure that the frame is fit for purpose. A choice of frames are available for most windows, however be sure to check that the marine windows you are interested in are available in the glazing and frame options you require.

When updating your windows, be aware that some manufacturers’ technical details are different to ours and may require us to find alternative solutions. For instance, if you would like to upgrade your old single glazed windows from a different supplier to our purpose built Jubilee clamping double glazed windows, then you would have to check your current radii against ours - along with its flange size, its fitting method and its protrusion into the boat (in case you have inner window liners). This may seem and awful lot of measurements to be taking, but at Channelglaze we have years of experience and deal with this kind of enquiry on a regular basis. To help you, below are some brief descriptions of our frames and their technical details.

SINGLE GLAZED HEAVY DUTY - Click here to view frame

Channelglaze’s Heavy Duty frames are the standard frame type for our single glazed option. They are the cheapest available frame and provide a durable, modestly priced window. These are face-fixed with visible fixing screws on the outside frame, pre-drilled and countersunk for no. 6 screws and ready to fit. To enhance the aesthetics of our Heavy Duty frame, fixing screws can be powder coated to match your desired finish. For more information on powder coated screws please see our Fixings and Trims page.

SINGLE GLAZED DELUXE - Click here to view frame

When a more luxurious single glazed window is required, we recommend our Deluxe frame. Like the Heavy Duty frame, the Deluxe is face-fixed. The difference is in thr concealed fixing channel around the window, where the screw holes are located. Providing that the screws are fixed flat into the countersunk holes, the concealing gasket will also lay flat, though care needs to be taken when inserting the concealing gasket. For more information please see our Fitting Instructions.

SINGLE GLAZED SWIFT FIT (CLAMPING)… Click here to view frame

For luxurious single glazed windows, this frame certainly meets the standard. Although more costly than our other single glazed windows, a matching, complete clamp frame, foam sealant tape and fixing screws are included in the price. These clamping windows are fitted on the inside by means of an inner clamping frame, which is pre-drilled & assembled together with the main frame to ensure that all fixing holes are in alignment. The clamping ring is formed to match the entire outside frame, ensuring a tight fit and reducing the risk of leaks. There are no fixing screws visible from the outside, leaving the frame looking tidy and professional and also allowing the finish to be unaffected by screws or gaskets. No fixing holes have to be drilled to the hull, saving on labour time & reducing the risk of the corrosion to the steelworks at a later date. Please ensure that the clamping ring is accessible in case a re-glaze is required.

DOUBLE GLAZED DELUXE… Click here to view frame

Channelglaze’s Deluxe frames are our standard double glazed option. They are face-fixed with visible fixing screws on the outside frame.

²   The frame is built with a slopping inner condensation channel to accommodate for the tumblehome (inward incline) on the sides of the boat.

²   The condensation can then drain freely and easily to the exterior of the window by means of its drainage slots.

²   At no point is the double glazed unit itself sat in water, due to a raised flat aluminium platform.

²   The condensation channel traps approximately 90% of the condensation that can form on the glass and the frame. The drainage slots are positioned on the bottom of the main frame and sometimes to a horizontal centre bar, depending on which opening you chose.

All of our frames are pre-drilled and countersunk for no. 6 screws and ready to fit. They have a concealed fixing channel around the window where the screw holes are located. Providing that the screws are fixed flat into the countersunk holes, the concealing gasket will also lay flat. Please note that care needs to be taken when inserting the concealing gasket - for more information please see our Fitting Instructions.

DOUBLE GLAZED FLUSHLINE… Click here to view frame

This frame is exceedingly luxurious, and yet it is not one that many are familiar with. It is very similar to our double glazed Deluxe frame, but, as its name suggests, this frame sits more flush to the steelwork of the boat. The concealed fixing channel is also slimmer than its Deluxe counterpart. This profile is used when it is preferable to manufacture double glazed arched top windows as an alternative to double glazed clamping.

DOUBLE GLAZED JUBILEE (CLAMPING)… Click here to view frame

This clamping, double glazed frame really is a cut above the rest. The whole development of our Jubilee window was designed from the Jubilee frame, and consequently the window is entirely devoted to this frame. The frame is fairly similar to our single glazed, Swift Fit frame, as they are both fitted from the inside by means of an inner clamping frame. This is pre-drilled and assembled together with the main frame, and no fixing holes have to be drilled into the hull. The Jubilee frame looks so professional and well-designed that heads will be turning. There is however only one Opening Option available, though by no means is this a bad thing: quite posibly the finest opening we offer, the fulll hopper with a removable pane for hot summer days comes as standard with this fantastic window.
