Penguin Parade Visitor Centre

With the new Penguin Parade Visitor Centre opening last week, it’s a good time to look back on this spectacular project.

Celebrated as an “environmental star on the horizon” by Phillip Island Nature Parks, the structure is full of sharp angles and dances with light. The centre features retail and dining spaces, a theatre, and a dedicated science and education wing.

In February, a member of our team headed down to Phillip Island for pictures of the centre as installation of the window and door systems was wrapping up.

The Phillip Island Important Bird Area supports up to 32,000 penguins and the Visitor Centre, located inside the IBA, welcomes about 700,000 human guests a year, all of whom are eager to view the fairy penguins.

Architects from TERROIR began talking with members of the EDGE Architectural team in early 2017. They needed window and door systems that could meet specific performance requirements and accommodate the unique design of the building, particularly, “large triangulated openings with increased complexity”.

U-MAX™ SG150 and U-MAX™ Door thermally broken suites were chosen due to their U-values and SHGC, and the design freedom the EDGE suites offer.

Kane Constructions was appointed to coordinate construction of the project and ensure strict controls in the environmentally sensitive area. IND Window Fabrications handled the glazing and install of the EDGE systems.

The Penguin Parade Visitor Centre project has been highly anticipated by our team, and we plan to head south to Phillip Island soon to enjoy the splendor and capture new photographs to share with you.

Penguin Parade

The Penguin Parade on Phillip Island is the most visited tourism destination in Victoria, with up to 3800 people every evening coming to see the penguins come ashore in a spectacular but sensitive landscape. At the same time, Phillip Island Nature Parks has become a pre-eminent authority on care for penguins and development of penguin habitat. The new Visitor Centre for the Penguin Parade has to carry the ambitions of this tourism and conservation program across iconographic, experiential and functional contexts.

Just released: new EDGE catalogues

It’s been a while since our last complete EDGE™ catalogue update in late 2017. So much has changed within the U-MAX™, MAX™, and GEN™ ranges, and we’re eager to share it all with you.

Eager to start exploring on your own? Click on the button below for the range you want to check out first. Or, if you prefer a guided overview of the new products and product updates, scroll on down the page.

A review of changes across the ranges

  • The updated catalogues feature fresh project images, illustrating new and relevant applications. More project images are featured on in the project gallery.
  • You’ll find assembly procedures with illustrative photos and explanations in all three catalogues, including how to seal a frame joints and how to fit a watershed. The appropriate sealing of a product and the redirection of water is a critical part of any long-term performing system.

The MAX™ catalogue

New and updated:

  • MAX™ 100 Front Double Glaze – 20 degree splayed coupler added to the range
  • New MAX™ 150mm Front Double Glaze 40mm pocket, internal glazed sill/transom
  • MAX™ 150mm Truth head/sill, which can be used on both front glazed and offset glazed suites
  • SG182 Rocket Mullion added to the range
  • New MAX™ Sliding Window, complementing the U-MAX™ version released in 2018
  • Change to the Bifold Door, a new Pivot Set conceals head machining and makes it simpler to load rolling gear into the head
  • MAX™ Sliding Door, Glaze-in Frame Option allows “zero threshold” sill and reduces assembly costs and metal costs
  • MAX™ Sliding Door acoustic door panel is more elegant, cheaper, and functionally superior at achieving the optimum glass separation for acoustics compared to the typical practice of a two-panel door fitted inside a two-panel door to create a 100mm airspace. Our new arrangement uses a fixed panel which improves the function and appearance of the door significantly, together with resolving roller adjustment issues and the inability to clean between the “sandwiched” sliding panel
  • MAX™ Sliding Door 100mm deep door rail, with two screw flutes for visual appearance and strength
  • New Curtain Wall bracketry, extending the use of these brackets with our three curtain wall systems
  • New Heavy Duty 150mm sub head because the nature of our projects tend to be larger buildings and engineers are more closely scrutinising sub frame strength
  • Rationalisation and redevelopment of 100mm and 150mm sub framing for more versatility and strength
  • SG182 sub head introduced which can be used unbroken and thermally broken
  • Sub Framing, new expressed 70mm and 200mm rectangular box sub jamb/sub sills, as shading and privacy is becoming more important these offer a unique way to “frame” a window
  • Tilt Only and Turn Only hardware options added to the tilt and turn window

The U-MAX™ Catalogue

New and updated:

  • The addition of SG182 thermally broken structural glazed as a framing system; SG182 has a 40mm rebate and is coming into its own in dealing with large spans and acoustic IGU makeups of 32-34mm
  • New CW142 thermally broken curtain wall; our versatile Polyamide beaded curtain wall creates a number of rebate depths, reaches less than 1.8Uw ratings, and tested to comply with Passive House air infiltration ratings; as NCC 2019 takes effect, our industry will require significantly improved window systems to comply with the more stringent energy requirements
  • Added a Sub Frames section in the catalogue
  • Added a Glazing Adaptors section to allow thermally glazed adaptors to be more easily found
  • Change to the Bifold Door, with a new Pivot Set which conceals head machining and makes it simpler to load rolling gear into the head
  • U-MAX™ Sliding Door redesigned door stile to Polyamide which improves the appearance of the product and easier adaption of mortice locks
  • Tilt Only and Turn Only hardware options added to the tilt and turn window.

Dissecting the EDGE DNA: true metric footprint

Commercial window systems go metric

Aluminium commercial framing systems originally came to Australia in the early 1960s from North America. They were released as an imperial dimension frame and other suppliers adopted the same footprint, with maybe a slightly different glazing pocket. The name “400 series” came from “4 inches”.

Australia metricated in 1966, yet today, that same product developed in the 1960s is still mostly imperial dimensioned. Here we are, 50 years later, and they’re still selling the same product. The choice to stick with the past is mostly attributed to the legacy of existing systems. It was simply too hard for companies to redesign decades worth of old product.

When given the opportunity to develop legacy-free suites, our R&D team decided to break free from 50-year-old technology and engineered the EDGE Architectural ranges with a true and complete metric footprint. Our systems offer a complete range of metric products, scoped from thermal break to double glazed and back into single glazed.

The EDGE Architectural ranges break free from the thinking of the past. This innovative and fresh design allows for energy efficiency, visual unity, design freedom and interchangability of U-MAX™, MAX™ and GEN™ frames across a façade.

Our metric footprint makes EDGE Architectural Systems better by units of 10.


Dissecting the EDGE DNA: external screw

The EDGE Architectural external screw: small and mighty

The form and function of the U-MAX™ and MAX™ front glazed suites get a major boost from an innovative assembly design utilising a humble, unassuming piece of hardware, an external screw.

Support where it’s needed

external_screw3We took a screw with a square drive head and moved the glazing pocket marginally further back. The glazing pocket is set at the perfect distance to get the best strength, stop transom rotation, support the load and drain water. No other front glazed system supports transoms as well.

Frame fixing external to the glazing rebate provides structural support of the frame and glass without interfering with drainage. The joint won’t open up and allow water in.

Break from tradition

Traditionally, systems either didn’t have a front screw at all or the screw came through the glazing pocket.

  • Often meant the split mullion needed to be wider than horizontals, losing visual unity.
  • A countersink operation was required to allow the mullion to mate.
  • The screw was placed central in the pocket and didn’t deal as well torsionally under wind load or take the dead weight of glass.
  • Without blocking off the glazing pocket, this scenario invited water to land on the screw and track underneath the pocket on top of the glass, making weathering suspect.

By breaking from tradition, we addressed all the above issues and delivered huge benefits with a little screw.

The unique frame assembly of EDGE Architectural differs from what everyone else does with a front glazed system. It’s just one more neat little difference with our front glazed system. All these little differences add up to a major difference in performance and aesthetics.


Dissecting the EDGE DNA: High Performing Gaskets

Applying the core principles of drainage for better window systems: the best practice gasket

Very few companies have seriously addressed the issues related to “controlled leakage” of architectural window systems. Commercial windows are designed to leak. Vertical members (jambs and mullions) are down pipes and horizontal members (especially transoms) are gutters. This core principle of drainage through the frame into a subsill is what all commercial framing systems are supposed to do.

Unique in Australia, EDGE™ framing gaskets are top loaded into the window frame and made from co-extruded Santoprene™ with a rigid backing. This rigidity results in audible feedback, a click, when the gasket is fitted. These gaskets can be used on both sides and treated either as a captive or roll-in wedge in one. It fits relatively flat into the pocket and does not detract from the sightlines. It is easily fitted in the factory or on the job site.

Together with proper care and manufacture, and our Watershed methodology, EDGE Architectural provides a high performing, durable and aesthetically pleasing glazing system.

An example of shrinkage in a non-EDGE Architectural system.

Traditional “roll-in” wedges have been used in our industry since window manufacture began. Usually manufactured from PVC, roll-in wedges are commonplace in the residential window industry, but have a poor reputation in the commercial market. As PVC shrinks, a roll-in wedge can quite easily roll back out.

In many markets, especially in Melbourne, commercial products are silicone glazed. This practice contributes to poor manufacturing processes. Dry butted frame joints leak – don’t believe anyone who says differently – and silicon attempts to mask this poor manufacturing. Silicon glazing quite often is used to stop water entry (to treat a window like a fish tank), but it only serves to mask a larger issue. Eventually, service problems will surface.

Shrinkage is a common occurrence with traditional PVC gasket wedges; shrinkage leads to leakage. Best practice and sustainable construction demands using high performance, purpose designed seals. These better performing gaskets don’t shrink, stay UV stable and don’t fall out when properly fitted.

The EDGE Architectural DNA, the feature set and performance principles, ensures our thermally broken range, double glazed range and next generation single glazed range deliver better results for our customers.
