Glazing Options
The extensive range of glass products that is available in today’s market grows every few months. Architects and specifiers alike use this wide range to offer to their customers ideas sorted by benefit, solution and performance, in an attempt to find the options that best suit. At Channelglaze, we believe that we also can offer a huge amount of advice in this area.
Channelglaze offers an extremely broad range of glazing options. These include: textured glass (please see the available single and double glazed textured options below); coloured tinted glass; differing thicknesses of glass; Pilkington ‘K glass’; laminated glass; sandblasted glass; polycarbonate; leaded stain glass designs and etching. There are in addition a number of films available on the market for controlling heat, glare, privacy, security, safety, anti-graffiti and decoration. We also offer ClearShield (see double glazed notes for further details) at an additional cost.
Any combination of the above can be utilised in our windows in order to tackle any combination of solar control, thermal insulation, fire protection, noise control, safety, security, self cleaning and decoration.
As standard, the entire Channelglaze range is glazed utilising 4mm toughened glass. In doing so, we ensure that our windows comply with Category ‘D’ of the Recreational Craft Directives (RCD) 1994 and the Recreational Craft Regulations (RCR) 2004. We can and have manufactured windows to comply with Categories ‘B’ and ‘C’ of these directives and are happy to offer additional advice on such projects.

Single Glazed…
As standard, Channelglaze Ltd uses 4mm toughened clear glass to glaze its single glazed windows. This can be changed to suit your needs when placing your order. Most boat builders incorporate a couple of privacy windows utilising Stippolyte textured glass for bathroom windows and such like. By incorporating textured or decorative glass, you can add privacy and meet requirements both aesthetic and practical.
Other bespoke projects we have undertaken have included the utilisation of tinted glass for increased solar control and slight privacy where possible. When choosing your desired glazing options please check the Pilkington website (
www.pilkington.com
) for ideas and we will let you know the availability of your choice. Below are some of the more common glazing options seen on the canals today.
Toughened G
lass
Overview
Our standard ‘Clear’ single glazed windows use our 4mm toughened clear option. Toughened glass is up to five times stronger than ordinary glass of the same thickness. Because of its increased strength, toughened glass allows architects and builders far greater scope in their use of glass in buildings. It meets world-wide safety standards for glass subjected to accidental human impact at the highest level of severity. Wherever the benefits of ordinary glass need to be combined with extra strength, safety or heat resistance, toughened glass can offer a complete and proven solution.
Toughened glass is manufactured by subjecting the desired size of glass to a heating and cooling treatment whereby high compressive stresses are set up at the surfaces with balancing tensile stresses in the centre. The high compressive surface stresses give the toughened glass its increased strength.
Benefits
Offers a complete and proven solution for impact safety and strength:
²
Up to 5 times stronger than ordinary glass of the same thickness.
²
Conforms to the requirements of BS 6206: 1981 Class A as well as European Standard BS EN 12600 and many worldwide safety standards.
²
Is suitable for double glazing.
²
Ideal for use in countless applications, from windows to barriers, interior design, curtain walling etc.
²
When broken, toughened glass shatters into small, blunt-edged fragments which reduce the risk of personal injury.
Textured Glass
Overview
Channelglaze uses 4mm toughened glass as standard for our basic textured glass option. Available in a variety of shapes and designs, our standard textured glass is ideal for use in those parts of the boat requiring a little more privacy. In addition, textured glass simply looks attractive – from inside and out – and in addition brings extra light into rooms.
Available in five levels of obscuration, chosen depending on the level of privacy you desire, our variety of shapes and designs gives you total control over the look of your window. All our toughened panes are suitable for use in double glazed windows.
In particular, glazed doors, and glazing adjacent to doors, should use toughened glass adhering to EN 12600 standards. Low level glazing and bathroom areas are
Premimum Collection
Overview
Our premium collection offers the absolute finest in decorative glass. In a choice of several designs and aimed at customers looking for a luxurious, highly attractive window, our premium collection of glass offers you and your boat the chance to go that little bit further. With the extra lighting provided by a window from our premium collection, you'll be happy you chose Channelglaze.
Sophisticated and stylish, the premium collection perhaps offers less privacy than our standard glass. But where it may therefore be less suitable for bathrooms or other private boat areas, it is perfectly designed for those important rooms you want to look their best – both inside and out.
We will toughen any design if you desire, for purposes of safety or noise reduction. Be sure to see a simple of your chosen glass design prior to confirmation of your order.
Tinted Glass
Overview
Our body tinted glass, available in a choice of colours, is visually appealing and highly practical. Reducing glare or offering good solar control, tinted glass offers the boat owner interior and exterior solutions, whilst also being distinctive and attractive.
With a range of thicknesses available, our tinted glass can also provide enhanced strength and spans, as well as noise reduction and better lighting during the daylight hours.
Laminated Glass
Overview
An alternative way to ensure impact safety onboard, laminated glass will break after impact, but simultaneously stay in place. This means of preventing injury is sometimes seen as preferable to simply toughening the glass.
Though possessing the same strength as ordinary glass, it is the 'sandwich filling' of a plastic interlayer, placed between two pieces of glass, which gives laminated glass its particular quality.
It is this interlayer which hold the whole window in place should the glass be broken: there will be no shards that can injure a person, and no hole to provide access for an intruder.
Laminated glass is produced by combining two or more sheets of glass with one or more plastic interlayers. Reducing the risk of injury in accidents, and suitable for double glazing, laminated glass might be particularly useful in doors on your boat, and fonforms to BG 6206: 1981 Class B standards.
Double Glazed…
For our double glazed windows we offer a range of double glazed unit combinations and utilise Super Spacer
®
as our space cavity system. These unit combinations can be utilised to find solutions for a number of requirements, including solar control, thermal insulation, fire protection, noise control, safety, security, self cleaning and decoration. Double glazing, compared to single glazing, cuts heat loss in half due to the insulating air space between the glass layers.
At Channelglaze Ltd we also apply ClearShield Glass as standard to our double glazed windows. Working just like a ‘non-stick’ cookware layer, ClearShield acts as a lasting protective barrier on the surface of the glass. It stops grime and other residues from bonding with the glass. Its unique ‘non-stick’ action makes it difficult for dirt to build up quickly and bond to its surface.
Below is some information about the spacer system used in our double glazed windows, some information on the ClearShield treatment that our double glazed units receive,
and some examples of unit combinations commonly used within the boating industry.
Super Spacer®
The world’s first all foam, NO-Metal spacer system
Super Spacer’s all foam, NO-Metal formula provides:
Thermal Performance
Windows lose and gain heat by conduction, convention, radiation and air leakage. Conduction is the movement of air through a solid material – touch a hot skillet and you feel heat conducted from the stove through the pan. Heat flows through a window in much the same way.
Unlike metal-based spacers, the all foam construction of Super Spacer is non-conductive, blocking heat flow through the window. By blocking the heat escape path, Super Spacer provides one of the best thermal performances in the industry.
Durability
Unlike metal spacers, Super Spacer can bounce back when put to the test against winds, temperature fluctuation, rain, snow and UV light. The foam construction of Super Spacer allows it to expand and contract as needed, but it always return to its original shape. Without Super Spacer’s 100 percent memory formula, windows can eventually crack and lead to seal failure.
Super Spacer’s durability is proven by its outstanding performance in the industry’s toughest durability test – the P1 Chamber. Super Spacer units withstand 140-degree Fahrenheit temperatures, 95-100-percent humidity and constant UV bombardment.
Mould Prevention
The fact that Super Spacer is non-conductive means that it also protects a major household threat: mould. Window condensation can lead to moulds that increase the likelihood of allergens, including fungi, viruses and mites that could cause respiratory infections, allergies and asthma.
Mould needs moisture to grow. To keep condensation off of glass, windows need to have the warmest inside surface temperature as possible – and the world’s warmest edge occurs with Super Spacer.
Sound Absorption
The closed-cell polymer foam in Super Spacer transmits very little sound compared to conventional metal spacers. Another reason you’re more comfortable at home with Super Spacer.

ClearShield…
The multi-award winning ClearShield System has been specifically developed for protecting and maintaining glass surfaces. Unique solutions for renovating glass already installed are also available. The innovative ClearShield System offers customized solutions to all glass users.
ClearShield, the protective element in the System, works like a ’non-stick’ cookware layer applied to glass surfaces.
What does it do?
²
Keeps your glass looking like new
²
Always easier to clean
²
Resists staining and discoloration
The Problem: Glass Corrosion
Just as metal rusts, glass suffers corrosion. This is caused by exposure to its environment as well as the physical and chemical properties of glass.
While glass may look smooth, it actually consists of microscopic peaks and valleys.
Depending on the type of environment, such as showers, decorative, architectural, windows/sunrooms, marine and airports/train stations, different contaminants fill these valleys and chemically react with the glass, firmly bonding to the surface.
Left untreated, these conditions can permanently damage the glass.
The Solution: ClearShield
ClearShield prevents contaminants from bonding to the surface and limits further damage caused by corrosion and chemical attack. Glass can be kept looking like new and easy to clean using normal cleaning methods.
Glass is a sensitive material that reacts with its environment. Dirt can quickly build up on your windows. Over time unprotected glass suffers permanent bonding of these residues, causing staining and physical damage. Often, washing does not mean cleaning. This is why when windows look dull it becomes very difficult if not impossible to bring back the shine, no matter how hard you try! Regular washing will simply not be effective spoiling the appearance of your windows.
Using ClearShield really does make a difference. Award winning ClearShield has more than 20 years of experience worldwide. It is the only glass that is both easy to clean and provides durable protection.

Toughened & Laminated
Double Glazed Units
Overview
Channelglaze utilises two panes of 4mm toughened clear glass as the standard throughout our double glazed windows range.
It is highly recommended that when ordering our units you incorporate into your design at least one pane of laminated or toughened glass. When choosing bespoke units, please ensure that you pay due consideration to this requirement. Laminated or toughened units offer heightened safety and security and are designed to break safely or remain intact on impact, reducing the risk of injury. Toughened and laminated glass can be partnered up with a number of different glass types, depending on the desired purpose of each unit. The below unit suggestions are just a small handful of the possible options open to you.
For the individual characteristics of both toughened and laminated glass please check the Single Glazed Glazing Options or ring us for further details.
Textured & Patterned Double Glazed Units
Overview
Channelglaze utilises two panes of 4mm toughened glass as the standard throughout our double glazed windows range. Our standard ‘Obscure’ double glazed windows use the 4mm toughened ‘Stippolyte’ pattern from Pilkington’s Textured glass range and 4mm toughened clear glass.
Textured double glazed units can incorporate a pane from the Pilkington range of Textured glass and the Oriel
™ Collection giving your home a look all of its own. These can also incorporate etched glass designs, Leaded and stained glass styles, sandblasted glass, Bevelled glass and other such bespoke designs. It is recommended to partner these designs with toughened or laminated glass.
For the individual characteristics of toughened, laminated and textured glass please check the Single Glazed Glazing Options or ring us for further details.
Tinted Double Glazed Units
Overview
Our standard tinted unit uses an outer tinted piece of 4mm toughened glass, whilst the inner layer is 4mm toughened clear. Bronze and grey tinted glass products are similar in energy performance: the primary purpose of the bronze or grey tint is to reduce solar heat gain. In addition, they reduces visible light transmission compared to
double glazed units with clear glass
or even other standard tinted glass products, such as green and blue tints, which offer significantly higher visible light transmission.
The tint has no effect on the
U-factor
,
but reduces solar gain - which may be a benefit in the summer and a liability in the winter, depending on local climate conditions. Importantly, this is the point at which low emissivity glass benefits the entire unit: tinted glass is useful in controlling glare, though solar heat gain and visible light transmission may be reduced relative to the performance of alternate glazing options, such as the low emissivity Pilkington K Glass™.
By incorporating tinted or coated glass into a unit, you can reduce heat in glazed areas during summer months, whilst maintaining a high level of natural daylight.
For the individual characteristics of toughened, laminated and tinted glass, please check the Single Glazed Glazing Options or ring us for further details.
Pilkington K Glass™ Units
Overview
If you are
thinking about using Pilkington K Glass™, we recommend incorporating 6mm toughened tinted glass as the outer pane. It reduces the amount of heat lost through your windows and it also controls the amount of heat (energy) from the sun going through the window.
The
Pilkington K Glass™ usually forms the inner pane of a K Glass™ double glazed unit. The coating reflects heat back into the room whilst also letting in free heat from the sun known as passive solar gain. Pilkington K Glass™ helps windows to achieve high Window Energy Ratings
Benefits
Recognised by the Energy Saving Trust as a significantly effective measure for achieving energy efficiency hence savings on fuel bills.
Helps to achieve high Window Energy Ratings when combined in a suitable framing system
Easily helps to meet and exceed the requirements of regulations concerning energy efficiency
Can be toughened or laminated for safety and greater security.
Can be combined with other Pilkington products such as tinted glass
How it Works
The glass in your windows absorbs heat and then radiates it again on the colder, outside, surface. Pilkington K Glass™ has a so-called low emissivity coating which is positioned on surface 3 (counting from the outside) of the double glazed unit.
The low emissivity coating is a poor radiator of heat. So the heat absorbed by the coated glass does not travel across the air gap to the outer pane and the cold outside world. Instead the coating reflects the heat back into the room.
Windows incorporating Pilkington K Glass™ allow heat from the sun through and keeps heat inside, making it easier and more cost effective to keep buildings warm.
