SJ Espacer

SJ Espacer is a premium, thermally broken large-format glass louvre window with 235 mm blades — designed for architectural façades that demand maximum vision and ventilation with minimal sightlines. It maximises ventilation when open and provides thermal performance and weather protection when closed, making it a practical, high-performance alternative to awning-style windows on technically demanding buildings.

Safetyline Jalousie SJ Espacer

Overview

Built for the façade where the window is the design statement, SJ Espacer is engineered to integrate seamlessly into the building envelope — fitting curtain walls (stick or unitised) or standing alone in traditional concrete façades. It suits commercial, multi-residential and architectural projects where a clean, expansive glass line and genuine ventilation both matter.

Key Differentiators

Largest blades in the range — maximum vision

235 mm glass blades (vs 135 mm on other SJ systems) reduce horizontal lines for a cleaner, more open façade.

Best-in-range air-tightness

air infiltration as low as 0.03 L/s·m² — the tightest of the SJ systems.

Highest acoustic rating — up to 37 Rw

the strongest sound reduction in the range, for the most noise-exposed sites.

Thermally broken frame

minimises heat transfer, supporting energy-efficiency targets.

Façade-tested for high-rise

AS4284-tested with high structural capacity; integrates into curtain walls or concrete façades.

Recycled, low-carbon aluminium

made from Hydro CIRCAL (min. 75% post-consumer recycled content).

We have a window of opportunity to build a greener future. Introducing a new low-carbon, recycled aluminium to help clients meet their sustainability goals.

Aluminium can be used over and over again without any loss of quality. As a lightweight, strong and highly versatile material, it plays a big role in everyday life.

SJ Espacer is constructed from Hydro CIRCAL – recycled aluminium made with a minimum 75% recycled, post-consumer aluminium scrap. Hydro uses the most advanced sorting technology in the industry to provide one of the highest recycled content in the market. Hydro CIRCAL 75R is guaranteed to have generated a maximum of 2.3kg Co2 per kg of aluminium produced. The global average is 16.7kg. The production process is fully traceable, and the product is certified by an independent third party.

The higher the recycled content, the lower the carbon footprint, and the better it is for the environment.

Watch the video below to learn how Hydro CIRCAL recycled  low-carbon aluminium is made.

Sustainable Aluminium

SJ Espacer is made from Hydro CIRCAL recycled aluminium — a minimum 75% post-consumer recycled content, guaranteed to a maximum 2.3 kg CO₂ per kg of aluminium against a global average of 16.7 kg. Fully traceable and independently certified. Watch how Hydro CIRCAL is made →

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.
