EDGE DNA feature set

DNA of EDGE Architectural framing systems

It’s not a window, it’s a system. A system with a DNA. The EDGE DNA instructs the development, form and functioning of all the EDGE Architectural framing systems.

By scoping U-MAX™, MAX and GEN™ with the consistent features, our ranges can be interchangeably specified for visual unity and consistent, reliable, excellent performance. You chose the suite based on a desired U-value and maintain a consistent sightline around the building even when you alternate between frames.

EDGE features: The DNA structure

Departure from traditional drainage

Into every life a little rain will fall. By designing the EDGE commercial aluminium window and door systems with this fact of life in mind, we incorporated a more practical and reliable solution to deal with water, be it from rain, humidity or condensation.


Another EDGE innovation is our frames rainwater evacuation system, Watershed. Watershed is designed to manage and direct the flow of rainwater through the frame system to the external perimeter of the building. The concealed transom drainage system directs water over and around the edge of glass.

  • The Watershed component is designed to be factory fitted during transom assembly, increasing quality control and decreasing costs.
  • Once properly assembled, Watershed ensures water cannot run from the end of the transom on top of the glass or the glazing wedge.
  • Watershed eliminates ugly external drain holes in the face of sills and transoms. Treating windows as “fish tanks” with silicone glazing doesn’t stop water entry and external drain holes actually become an entry point for water.
  • Good systems design allows water entry and effectively deals with drainage.
  • Watershed allows the safe passage of water in front of the glass, using vertical members (jamb and mullion) to direct water through the system for collection by the subsill.
  • Watershed can be fitted after frame assembly, a huge benefit if it is inadvertently forgotten during assembly. It can be snap fitted into the pocket above the transom and slid into place. This is not the preferred and recommended process, though and requires more careful caulking.

Where air goes, water will follow

The Watershed methodology ensures dry interiors and prevents the build up of still water, recurring condensation and even mould that can occur in standard framing systems.

More effective, more attractive window and door system drainage: no drain holes

Admit it. You think those drain holes in window frames are ugly. We agree.

Beyond being ugly, drain holes in the face of a sill leaves the system vulnerable to other things. Air pressure, water, spiders and insects, all sorts of things can get in there. Where air goes, water will follow.

That’s why when we designed the legacy-free EDGE Architectural framing systems, we did the research and testing to find a more effective, more attractive water drainage system.

Framing systems in general were meant to be gutters and downpipes, but many of today’s systems designers have forgotten this. We’ve taken a best practice approach with it.

Our solution delivers a better drainage result and allows us to eliminate the drain holes. The EDGE suites are premium systems with premium drainage.

Thermally broken windows: the EDGE thermal break methodology

Thermally broken window and door frames offer several advantages including energy efficiency, decreased condensation and reduced radiated cold, resulting in money saved and comfort increased.

After extensive research and testing, the EDGE team determined the best results could be attained for our clients by combining both Polyurethane and Polyamide strip technology in the U-MAX thermal break window and door frames.

Types of thermal break

Pour & debridge thermal break

The process of debridging removes a minimum of 5.5mm of metal, creating a break in excess of the requirements of the formal definition of a thermal break.

Polyamide thermal break

A Polyamide strip is crimped between two separate extrusions.

PBS curtain wall thermal break

A PBS curtain wall thermal break is a simple, efficient system with a thermal separator or spacer and external clamp bar which is through fixed to retain the separator and create the break.

Thermal break benefits

Long considered the “thermal wound” of a building, windows and doors notoriously allow outside temperatures inside, costing money, wasting fuels and reducing the usable space in a building. Thermal break offers a better way.

In colder climates, the thermal break reduces heating cost, as well as “cold spots” within rooms.

In warmer climates, the thermal break reduces cooling costs generated by the heat that transfers through a standard frame and radiates into a room.

In humid climates, thermally broken frames reduce condensation. Condensation on window frames results in water pooling on sills and often tracking onto walls and floors. Water damage and mould are the inevitable consequence of condensation on frames.

In contrast, condensation created by warmer, humid air inside a home contacting the glass made cooler by the cold air outside the home can be addressed by opening a window or running exhaust fans in the kitchen, bathroom or laundry area to allow the humid air to vent.

Increased energy efficiency in a building leads to lower energy costs and increased liability of a space. An environment with a more effectively controlled climate is more pleasant from wall-to-wall. The end user doesn’t find cold spots or hot spots they want to avoid.

Trump transom torque with the unique frame assembly of our external screw

The form and function of U-MAX and MAX get a boost from a seemingly insignificant little screw. An external screw.

Frame fixing external to the glazing rebate provides structural support of the frame and glass without interfering with drainage. Not very flash, and yet, very awesome.

Our decision for this unique screw placement means less stress on the joint, improved structural performance and ensured water tightness. The glazing pocket is set at the perfect distance to get the best strength, minimize tilt, support the load and drain water. No other Front Glazed system supports transoms as well as this.

The increased strength and decreased risk of transom torque prevents the joint from opening up and allowing 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.

A fresh look at glazing

Details. They’re your key. From little details, amazing projects evolve. The EDGE team understands this. We give attention to details often overlooked. By doing so, we can offer our clients options, options, options when it comes to glazing.

Captivated glazing bead

EDGE Architechtural’s one way pressure secured glazing bead: a glazing bead that won’t unseat

Encrypted into the EDGE DNA are captive pressure glazing beads, glazing beads that rock back rather than clip in and can’t unseat.

  • captive because it can’t jump out
  • pressure from the glass

Our captivated glazing wedge further secures the glazing bead and will not fall out.

To take that principle a step further in many cases, we can recommend the bead at the top of the light (instead of the bottom). From a performance viewpoint, systems can perform better this way.

Normal snap-in beads unclip due to poor glazing techniques or from being out of tolerance.

Our glazing bead locks into place by locating into a captive groove under pressure from a glazing wedge or foam rod in the pocket. Glazing beads can be used on the underside of transoms, ensuring water is better contained within the glazing pocket. The anti-drop out bead ensures the bead cannot dislodge. No other commercial aluminium window and door system offers this feature.

While the EDGE ranges continue to develop, all the suites rise from a foundation of international, best-of-breed features to ensure consistent performance and quality. The captivated glazing bead is one of these.

High performance gaskets

“Top Loaded” glazing wedge

  • Captive high performance gasket
  • Easily factory fitted
  • Factory environment allows for greater quality control and cost savings
  • Readily replaceable for reglazing or if damaged
  • Consistent appearance finished result over silicone glazing

EDGE glazing wedges are high performance, co-extruded Santoprene and are colour coded for easy identification. All are captive, meaning they don’t require a captive on one side and roll in the other.

The wedge gives an audible “click” as the co-extrusions keys into the pocket, ensuring the wedge is properly seated. Santoprene is the best material available for long-term durability and anti-stretch features.

The co-extrusion backing gives an easy identifier of thickness, an audible “click” when engaging and further enhanced anti-stretch capabilities of the wedges. Our top-loaded pocket was designed for fitting the glazing wedges. When glazing, the wedge cannot be dislodged.

The inner leg on the pocket is lower than the face of the frame. This gives a perfect detail to run a bead of silicone prior to fitting the inner wedge. With the leg lower than the face of the frame, there is less chance of ooze. Pocket design is clean and uncluttered with no restricting legs inside it.

The back of the pocket is 5mm wider than the gap. This make it easier to angle glass into the pocket.

Pocket depth is 28mm on deep and 17mm on shallow, allowing for a full 12mm glass bite and edge distance requirement as perAS4555 (insulated glass units) Table E5.1.

Internally or externally glazed

Most suites can be internally or externally glazed.

Aluminium window and door frames

EDGE Architectural Glazing Systems heralds a fundamental change in Aluminium Industries’ complete product range with an ongoing development of three separate product groups:

U-MAX™, the double glazed, thermally broken suite
MAX™, the double glazed suite
GEN™, a single glazed “generational change” encorporating a solid metric range and the EDGE design features.


Standard 60mm outer frame with optional 44mm frame.

Mix and match framing

Mix, match and marry for happily ever after. Different framing systems of the same depth can be used together to alter the glazing plane.

Multiple frame options

100mm or 150mm frame depths available.

Full metric footprint

The Australian architectural window market, largely has not redesigned its base commercial products since the first systems were introduced in the early 1960s. Those products followed imperial dimensions and many follow the same form today. EDGE departs from the old imperial standard. Incorporating frame and track systems, all EDGE products offer consistency in metrication.

Unique design principles

  • U-MAX thermal extrusions can be offered in non-thermal frames when thermal break is not required
  • Cost savings by choosing MAX frames when indicated compared to using U-MAX throughout
  • The same suite can be used on all facades, ensuring exactly the same appearance
  • U-MAX suites offer low profile 44mm face frames or 60mm frames
  • Common head and sill sightlines for consistent appearance and aesthetics
  • Products can be coupled together and mixed to change the glass plane or make manufacture simpler, especially with doors
  • EDGE Architectural offers both polyamide and polyurethane thermal break technologies to employthe correct system for the specific application and assure cost effectiveness or aesthetics
