Glass Partitioning

Glass Partitioning and Dry Joint Frameless GlazingGlass partitioning provides a modern and sophisticated solution to providing internal enclosures and wall partitions for a variety of applications.One of the clear benefits of using glass partitioning is that light can still pass through, thus creating a feeling of space and a light airy environment. The glass panes require a system of jointing to give strength to the overall partition where each abuts the other (discussed below), and for this Switchglass uses the latest in Dry Joint systems.

There are many different options when choosing the right glass for your partitioning project, which will vary according to your individual and legislative requirements. When you need absolute privacy you might choose sandblasted or diffused laminated glass. The latter will afford some degree of acoustic baffling; double glazed panelling will provide increased soundproofing.  For partial privacy, there are many very attractive, decorative adhesive films that may be applied; enquire about our range.

Alternatively, simple decorative designs or your company branding can be sandblasted on to the glass.

For clients who would like to embrace the latest in technology, Switchglass’ advanced Switchable Privacy Glass can be used to provide absolute privacy at the flick of a switch or touch of a button.

 

Single Skin Glass Panels

The maximum recommended height for single skin (as opposed to double glazed) toughened or laminated glass partitions are:

 

Thickness (mm) Height (mm)
10.00 2400
10.88 2400
12.00 3000
12.88 3000
15.00 3500
16.80 3600
19.00 4200

 

It is also recommended that glass is embedded at least 12mm into its supporting channel to hold the glass securely in place. For most applications the glass edge is flat polished with a standard back arris (bevel) for silicone butt jointing.

 

Dry Joint Frameless Glazing

Utilising our crystal-clear, easily installed acrylic dry jointing channel as a low-profile integral connector, we affect a discreet join that is virtually invisible between the panels achieving an overall, seamless finish.

Where required, we also produce edgework in the form of a precise size and/or angle on the back arris for specific dry joint systems such as angled or curved layouts.

Full height partitions will often require some form of manifestation or mark to meet current regulations and prevent people from walking into them. This can be achieved by sandblasting the surface of the glass with a manifestation of the customer’s own design, or by adhering some visible emblem on the door or partition at eye level.

 

Windows

Are you confused?Secure Glass Men At Work

Smart glass, electric glass, heated glass, energy efficient glass, tinted glass, toughened glass, tempered glass, insulated glass units, double glazed units, privacy glass, switchable glass, glass sliders (when did a sliding glass door stop being a window?), patterned glass, art glass, skylights . . . But who talks about WINDOWS anymore?

We seem to be losing the usage – let alone the true meaning of the word. Most people today are more likely to immediately connect the word to a popular computer operating system. Or the more romantic will connect it to the phrase ‘window to the soul, or heart’. Those who are busy would more likely reflect upon ‘a window of opportunity’. You see, a window is basically a hole in a wall. And because we can see through that hole, see beyond it, we ignore its significance and nomenclature. We look out, or through, and ignore the fact that there is a specifically constructed frame – perhaps made from wood, aluminium or even UPVC (Un-plasticised Poly Vinyl Chloride), and that frame holds a pane of glass over the hole. Even a ‘skylight’ is but a framed window in a roof – another hole.

Windows did not always hold glass however. If we go back far enough, the derivation of the word ‘window’ described only a hole in a wall to let air in or smoke out, and it would be shuttered in inclement weather. It was the Romans who first started putting glass in these holes to keep the weather out. We do have a lot to thank the Romans for, and for more than just glass, of course. But it was a rough glass they had used, and not all that transparent.

The improvements in the clarity of glass over the centuries brought with it a new set of problems however. Privacy was threatened – if you can look out with clarity, others can look in with equal clarity. This instigated another development – shutters. Shutters are still widely used in houses all around the Mediterranean today, but in the more northern climes they chose to develop something more easily pulled aside: drapes and curtains. This spawned a whole fashion industry which exists to this day and has maintained its popularity in most of the former British colonies (including, and especially, Australia). Next, came the development of blinds; another big industry that is growing even as I write.Today, however, technology has given us such vast improvements and innovations that we have panes of glass that are in and of themselves able to become obscure or transparent at the mere flick of a switch – Switchable Privacy Glass. Polymer-Dispersed Liquid Crystals entrapped between two panes of glass with a power source to activate it. Amazing! But then, we are, after all, in the age of microchips, satellites and nanotechnology. Whiz-bang stuff!

I think it will be a while before we see the total demise of blinds, drapes or curtains, principally because of their potential, decorative nature, but the day will soon be upon us when the simple affordability and effectiveness of electric glass products such as Switchglass’ Switchable Privacy Glass will see it as being the glass of choice to afford privacy. And remember – next time when you gaze vacantly out through that apparent hole in the wall at the world beyond – what you are looking through is a real W-I-N-D-O-W. Nothing to do with Microsoft, but perhaps, conceivably, a space laden with opportunity.

Hollow Glass

Glass doors and windows are the primary means through which we commune with both the inside and the outside of a building, permitting light to flow into the interior (in daytime) and allowing us expansive views.

 
They can also be decorative, but the natural indoor and outdoor heat exchange means a great influx of heat in summer and a great outflow of valuable energy, through generated heat, in winter. This, traditionally, has led to wasteful energy consumption through the heating and cooling of buildings.

Insulating glass is the solution, providing energy-saving, environmental protection and comfort (noise reduction), yet still enabling us to commune clearly through our glass.

Insulating Glass, usually referred to as Double Glazed in Australia and New Zealand, also comes under the category of Hollow Glass, though this intriguing name refers also to a much broader category of glass products including bottles, glass spheres or bubbles.

Energy conservation of buildings is arguably a more important topic today and Hollow Glass (the IGU and Double Glazed Unit) continues to play an important role in this field. Over 30% of energy inside buildings flows away through doors and windows. This nagging fact alone ensures that the energy conservation capabilities of doors, windows and glass curtain walls will continue to be an important topic in the glass industry.

Double Glazed units need not be dull: spacing bars, made from fire-resistant macromolecule plastics or colourful aluminium, can be embedded within the hollow glass and can be different in colour and shape.

Low-E insulating glass filled with inert gas: Low-E coatings on glass effectively block heat radiation. Low-E Hollow Glass filled with inert gas can further reduce the direct transmission of heat energy and reduce the thermal transmission coefficient of glass. Hence the ‘Energy Efficiency’ tag I often apply to the product.

 

Laminated Glass - Double Glazed

In order to achieve different effects, Hollow Glass units can also be combined with coated glass, toughened glass or laminated Switchable Privacy Glass to form various desirable composite products.

Trends In Glass

Glass Design and Lamination

Here we have another product designed to aesthetically improve the appearance of glass partitioning and glass-clad buildings, this time from SEFAR:

SEFAR Architecture Vision Screen

SEFAR ARCHITECTURE VISION

SEFAR Architecture VISION is a fine black precision fabric that can be coated with aluminum, copper, aluminum/copper, chromium, titanium or gold: the metalised fabric side can have a special design printed on it.

SEFAR Architecture VISION is laminated in glass when used in façade elements, whereas in double glazing it is stretched between two panes and fastened to the frame. If only the exterior surface is coated, the view in from outside is reduced and the fabric is also given outstanding energy-transmission reduction values. The rear surface (the side facing inwards) of the fabric is black and therefore neutral in color. From inside and from further away than 3m the fabric cannot be seen.

In addition to its aesthetic features, SEFAR Architecture VISION also reduces the incidence of birds flying into the glass. Furthermore, for indoor applications SEFAR Architecture VISION can also be laminated in plastics materials or used to create textile surfaces having a very special and unique look.

How the outer surface of the metallized fabric looks depends on how the light is reflected from it, whereas the black inner surface has little optical effect and so does not hinder the view to the outside.

LAMINATION INTERLAYER CHOICES

In addition, Eastman is also in the process of launching new solar interlayers for the architectural market. The line was introduced last year for the automotive market and offers UVA and UVE blocking features thanks to nano particles that are mixed into the interlayer.

Also featuring a line of interlayer choices, Bridgestone, which is based in Germany, offers decorative selections that can include imagery printed onto PET film that’s laminated to glass with EVA film. Its material can also be laminated with a range of materials including stone, fabrics, etc. The EVA is created to offer high-quality durability and will not bubble or yellow over time.

On the coatings side, Ferro features its S1de ONE enamels, which are new for the United States, but have been in use in Europe for some time. Most enamels are applied on the second surface as they do not have the weather-resistant features to be used on the external side one. Now, however, with this company’s new system the enamel can be used on the first surface.It is suggested that architects like this because they can build texture, create a matte effect, etc. because you’re not seeing the glass, but what’s on the glass. And color continues to be an architectural glazing trend, as does digital printing.

FROM THE GLASS AND GLAZING EXPOS

Trosifol is featuring PVB options for laminated glass. The two newest colors for the company are a 30-gauge completely opaque black and a 30-gauge completely opaque white. According to Christian Amad, director, these are already being stocked and sold. While North America compared to Europe typically does not use as much laminated glass, Amad says he has seen growing interest.

“We’ve seen more interest in the United States with custom glass, different thicknesses, etc.” he said, explaining that much of that interest is coming from the value-added benefits that laminated glass can offer. “We’re continuing to see companies start up laminated lines,” he added, “even in challenging markets.”

While glass companies are featuring examples of digitally printed glass, machinery companies are busy demonstrating the lines used to create these displays.

Shlomit Niva Tevet, director of marketing for dipTech, said they were seeing much traffic in their display booth as interest has been growing around the world. She said more and more companies are purchasing the line as digital printing can provide so much creative design freedom. Her company debuted two new inks, a conductive product that runs electricity to the installation as well as a skid-resistant ink for applications such as flooring, walkways and stairs. She said they also have plans to work more with architects directly in the future.

Glasstec also recently featured a number of special shows and exhibits, and “glass technology live” was again a major highlight. With the topic “Innovative Glass Functions,” Prof. Stefan Behling and his team from the Stuttgart University’s Institute of Construction Design showcased practical products for the near and distant future. These included a window incorporated into glazing without any visible frame construction, bent but still stable glass, organic, building-integrated photovoltaics as well as large-format façade elements. Together with the “Competence Center Glass, Window, Facade”, which combined know-how from various associations, these façade mock-ups formed the “Facade Center”. The “glass technology live” show was accompanied on all days by a free symposium on a variety of topics attended by numerous visitors.

All very interesting stuff as I think you will agree.

Glass Progress

So you think glass is just glass?
 

Well think again.

While you have been staring out your plain old window for the last decade, Glass has been undergoing a technological revolution.

This progress has been driven partly by man’s insatiable desire to ‘improve, and improve again’, but the key driving factor has been the building industry’s acknowledgement and embracing of the need to use better, safer, more durable – and most importantly – more Energy Efficient products in their construction. Yes, the glass industry is going Green – in a big way. And it is ironic, is it not, that glass has always had a slightly green tinge to it when viewed on its edge.

While the building industry throughout the western world has been constantly up-grading and improving Safety Standards, there has been a parallel drive in the Glazing Industry to improve its products safety performance and thermal loss and gain: old-style glass being notoriously bad at preventing heat and cold from passing straight through it – both ways.

Don’t worry ‘help is on the way’! A collaboration of scientists and technicians working on all these above problems over the years have come up with practical solutions. Even the earlier solution to the problem of heat loss and gain, Double Glazing, has been improved out of sight; I was wowed the other day on seeing venetian-style blinds within the glass of a sealed, double glazed unit. Do you realise what this means? You would never have to clean the blinds! Fabulous.

In respect to Safety: The improvements have been primarily in the strengthening of glass; prevention of shattering and breaking into dangerous shards; heat resistance in the face of fire; and the withstanding of high wind loads – ‘hurricane proofing’ in climatically challenged zones, but equally applicable in curtain walled (all glass) high-rise building.

In respect to Energy Efficiency: Besides the use of smart, tinted films being laminated into windows the scientists have moved towards thermochromics, a passively responsive technology where the optical properties of the glass change in response to heat (appearing to darken in the sun), and electrochromic glass that requires voltage to similarly create a gradual tint to dark grey. This latter system allows the glass to be controlled by a ‘smart’ building system, or overridden by an actual human.

Clever stuff, all of which has devoured billions of dollars in research and development funds over the years, and all, ultimately, to better our comfort in the buildings in which we spend so much of our time. Maybe we should just get outdoors more!

Sand and Our Glasses

HourglassWhat Is Glass?
 
As you kick your feet along Perth’s soft and white sandy beaches this summer, spare a thought for the glass maker of old as he shovelled tons of the silica sand into a raging hot furnace.

Processes have been modernised, but basically glass is still sand – a very high quality silica sand to which other materials are added. The resulting mixture is called a batch. Some of the other materials included in the batch are salt cake, limestone, dolomite, feldspar, soda ash and powdered cullet.

Cullet is broken glass. It can be left over from a previous batch or from the edges that remain after a batch of glass has been formed and cut to size. Adding cullet helps the batch melt more easily.

 
 

How Is It Made?

Glass is made by melting and cooling the batch. As the batch cools, it becomes solid without forming crystals. Crystals are three-dimensional building blocks that make a substance internally rigid. The lack of crystals makes glass technically a liquid, or an amorphous solid, but also benefits its transparency.

Much of our window glass is imported, but closer to home, one of the more significant deposits of silica sand in Australia is to be found in South Australia. This pale cream sand is processed here to manufacture colourless container glass for the wine, brewing, food, and soft drink industries.

“I Contacted You After a Home Invasion”

To:  May

Subject:  Thank you

 

Hi May,

Don’t know if you remember me, but I contacted you early on the morning on 27 June after a home invasion. I would just like to thank you personally for the wonderful way you helped me with my emergency. I had a huge pane of glass smashed in and needed to be at work for urgent business. I was very impressed (and grateful) for your obvious concern and the way you managed to get someone out to repair it so quickly.

I was also very impressed with Lee who came out to do the repairs. He did a great job and helped greatly with clearing up an enormous amount of small-sized glass fragments.

I only got to your company after phoning several other firms who were pretty unconcerned and unhelpful. I hope that Secure Glass appreciates the great job that you and Lee do and should I be unfortunate enough to need to replace any more glass, your company will be the first one I call. Keep up the good work.

Kind Regards,

Lyn
