Double Glazed Performance at Half the Price

Safetyline Jalousie is introducing a very unique Energy Saving Glass to its range to offer architects, building designers and facade engineers the thermal performance of conventional double glazing.

Pilkington’s Spacia is the world’s first commercially available vacuum glazing. Only a quarter of the thickness of double glazing, it offers an attractive solution to the problems of resolving building conservation with modern comfort as well as fulfilling modern requirements.

How it works

A vacuum glazed window unit consists of an outer pane of low emissive glass and an inner pane of clear float glass, separated by a micro spacer grid of small pillars each measuring just 0.5mm diameter and set 20mm apart. This grid ensures that the two glass panes are kept a fixed distance apart. The edges of the unit are welded to achieve an airtight seal.

During the course of vacuum glazing manufacture, the air in the space between the two panes of glass is extracted to create a vacuum via the extraction point (as opposed to filling the space with air or gas). Even a small vacuum is effective in reducing the conduction and convection heat losses, so the gap between the two panes can be reduced to just 0.2mm. The result is an excellent thermal performance from a unit that is only slightly thicker than a single pane of glass.

Why incorporate vacuum glazing into Safetyline Jalousie louvre windows

There is no doubt that louvre windows provide more airflow than most other windows so are an obvious choice to provide ventilation and cooling. Due to the continued evolution of standards and regulations around energy efficiency, improvement to construction methods and greater consumer expectations, the demand for double glazed louvre systems has been growing in recent years.

There are only a few double-glazed louvre windows available to Australian consumers at present. Unfortunately, all are manufactured offshore, come with a very high price tag, and while they offer excellent thermal performance, they do not necessarily meet other requirements such as balustrade compliance and fall prevention. Safetyline Jalousie’s vacuum glass louvre window will provide an alternative solution at an affordable price, with the ability to improve energy efficiency all year round and with the same design capabilities as the original JX Safetyline Jalousie louvre window.

Overall Performance

An analysis has been undertaken by Inhabit Group to assess the overall performance of the Safetyline Jalousie system with multiple products and panel sizes. Using THERM 6.3, the Australian Fenestration Rating Council (AFRC) total U Value and Solar Heat Gain Coefficient (SHGC) of the vision panels has been calculated based on actual sizes.

As can be seen from Table 1 below, the calculated U-Value and SHGC are outlined.

 

Benefits of vacuum glazing windows

  • Thermal performance equal to or better than that of most low-e double glazing but in the same thickness as single glass
  • Improved sound reduction performance when compared to a standard double glazed window (35Rw when incorporated into the Safetyline Jalousie system)
  • Cost effective alternative to double glazing
  • Vacuum glazing is a proven solution; installed successfully in the UK and the Netherlands and used in Japan for over a decade

Project Examples

IT Umeda Tower, Osaka Japan

This striking 22-storey tower is located in front of Osaka station. 1400m2 of Spacia Vacuum Glazing is installed in the northern facade called “Zero Energy Space”. Vacuum Glazing was selected for its superior energy and acoustic performance.

 

 

Mita Parkside Tower, Tokyo Japan

For this 25-storey high rise condominium standing alongside a busy highway, the high sound reduction performance was a key feature.

As the most recent addition to the Safetyline Jalousie family, Ali is still coming to terms with the fact that a typical telephone conversation will often be answered with “You’re calling from Safety what”? followed by having to sound out and spell the name “ja-lou-sie” (it happens to us all). Born in Lebanon, Ali has moved around a lot over the years, living in Cyprus, Sydney for most of his Schooling, as well as China and Hong Kong. He currently resides in Melbourne where he spends a lot of time in his garden or doing some sort of work around the house. (Not too dissimilar to many other Melburnians following the onset of Covid). With a very obvious cultured background, Ali is warm and talkative and he’ll get you talking too.

One of the Safetyine Jalousie originals, Rom (often mistaken for John) holds a great passion for the product. He says its “its innovative, a market leader and ever-evolving, very much like the company itself”. When you meet Rom, it is apparent that he is well-educated and well-travelled. Coming from a family of medical professionals, they moved around extensively and often. Last count was 125 countries. So nearly all of them! It’s really no surprise that Rom has mastered packing a weeks-worth of clothes and necessities into a carry-on bag. And when we say clothes we actually mean meticulously prepared outfits and accessories. When Rom enters a room, you’re sure to know it!

Adam is our strategist and big ideas generator whose somewhat reserved nature could have some mistake him as a bit of an introvert. But that’s only until this quiet thinker is given a whiteboard and a marker – and then there’s no stopping the dialogue! 7 Years in at Safetyline Jalousie, Adam is continually expanding on his knowledge of the construction industry and is incredibly driven in his pursuit to help create better buildings via the use of better products. When Adam’s not on his quest to improve Australia’s built environment he’s spending most weekends escorting one of his 4 young kids to birthday parties, sometimes multiple parties. He has some stealth survival tips for other parents currently in the same predicament.

Michael has become recognised at Safetyline Jalousie for his continually changing hairstyles (facial hair included). Buzz cut, undercut, dreadlocks, even a mullet. We’ve see it all. His current man bun could even be gone before we finish this sentence. Always up for a laugh, friends and colleagues love a chat with Michael, and his easy-going and approachable nature has earned him the respect of all staff. In fact, he even has a cohort of followers on the factory floor sporting his same hairstyles. Outside of work Michael has recently turned his attention to mountain bike riding. His very first ride ended with a pretty serious accident resulting in a deep puncture wound to his leg– it’s been a sore topic for his leg and his ego.

Our South American Native, Jonathan is more simply and better known as “Chilli” (no need to try and guess his country of origin). After 16 years of military service, Chilli joined the Safetyline Jalousie team for what he describes as “a change of pace”. Although his average work day might look very different these days, there’s no doubt that Chilli’s previous experience has contributed in shaping a culture of commitment, community and comradery within the production team – the very important engine room of our company. Driven by a sense of accomplishment, in addition to running Safetyline Jalousie’s production line with military precision, Chilli has recently been studying hard to complete his Master’s Degree in Business and Logistics.

Mandy has been with Safetyline jalousie since day one so would technically be considered a geriatric in “Jalousie years”. Whilst her role has changed and evolved over her time with the business, one thing that hasn’t is the happy and fun, team culture that she says “continues to make each day at work a joy”. As a mum of two little ones, Mandy thrives on new challenges and a little bit of chaos. Although, as a self-proclaimed clean freak, she ensures that all forms of chaos are kept in a very neat and tidy manner. We’ve also observed that Mandy appears to have an inherent fear of colour and will almost only ever be seen in black or white (or sometimes grey if she is being really out there).

As a busy mother of 4, Lisa is highly skilled in organising, delegating, and troubleshooting – the proficiencies which she also demonstrates in her daily management of the Safetyline Jalousie office. Lisa tells us that she lives by the saying “What doesn’t break you makes you stronger”. (No doubt she’s had to use this little piece or personal encouragement from time to time to deal with our infinite requests)! Always on the go, Lisa has a very active lifestyle and starts every day with a walk to the beach with her husband and two dogs. Of an evening she still has the energy to spare for star jumps and squats in her makeshift gym/ (our office) before heading home to her other full-time job as “mum”.

The younger brother of the co-founding sibling duo, “Nath” is the go-to for just about every technical, install, and manufacturing enquiry that comes via the business. Very early on, Nath’s product knowledge and problem-solving ability saw him organically take on the role of Operations, overseeing the design and management of Safetyline Jalousie’s behind-the-scenes work. When he’s off duty (and not answering a million questions), Nath enjoys spending time with his wife and 3 young kids. You’ll find him cheering on his son at weekend sports, enjoying the water somewhere along the Northern beaches and this lover of food is generally always planning his next big meal. Preferably a Lebanese banquet if anyone can suggest a restaurant he doesn’t frequent already.
