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.

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.

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.

Dissecting the EDGE DNA

The features of EDGE walk away from 50-year-old window and door technology to offer benefits relevant to today’s commercial building designs and standards. They’re so fundamental to the ranges, we call it our DNA.

The U-MAX™, MAX™, and GEN™ suites were designed and tested to meet needs both practical and imaginative. Reliability, longevity, and energy efficiency, combine with design freedom and system interchangeability. You choose the combination of frame and features to achieve your vision for your project.

In the upcoming months, we’ll take a closer look at each of the 10 elements in the EDGE DNA and review how they benefit your projects. Until then, get a quick refresher with the graphic below.

High performing gaskets: high performance, “top loaded”, co-extruded captive anti-stretch gaskets.

True metric footprint: not just imperial measurements converted to metric, the EDGE systems were originally designed in metric.

Mix-and-match framing systems: different framing systems of the same depth can be used together to alter the glazing plane.

Multiple glazing options: accepts 24-28mm dry glazed IGUs. Single glazed spandrel option available.

Internally or externally glazing: most suites can be internally or externally glazed.

Captivated glazing beads: one-way pressure secured glazing bead will not fall out when installed according to specification.

Thermally broken: Australian designed and manufactured thermally broken window and door frames.

Watershed: concealed transom drainage system directs water over and around the edge of the glass.

No unwanted drain holes: our Watershed system removes the need for drainage holes.

External screw: frame fixing external to the glazing rebate provides structure and support of the frame and glass.

Multiple framing options: 100mm and 150mm frame depths available.
