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.

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.


Carey Baptist project, featuring EDGE Architectural systems, explored in episode of Sacred Spaces

Purposeful architecture of Carey Baptist College discussed in Sacred Spaces

In this episode of Sacred Spaces, Rod Beel, Aluminium Industries’ R&D Manager, joins the conversation to discuss the role our MAX™ 182mm Curtain Wall suite played in helping the architects at Hayball realise the vision for the Carey Baptist project.



Sacred Spaces is an architecture and urban planning TV show broadcast on Melbourne Channel 31.


Bigger, better, EDGE-ier: new EDGE architectural window and door systems and updated documentation

Breezing in this season, we present to you the spring 2017 edition of the EDGE technical manuals

Team EDGE spent their winter months deep diving into development and documentation of the EDGE systems and we’re eager to share the results with you. We’ve detailed all the changes for you below.

Or, dive in and start exploring on your own. Download the complete technical manuals for the three systems, or the section for a specific suite within one of the systems from our documents library.

EDGE technical documents: new products, new designs, more benefits for you

Download the latest edition of our EDGE technical catalogues

The 2017 EDGE technical documents deliver the latest, greatest information on our GEN single glazed, MAX double glazed and U-MAX thermally broken ranges. The technical manuals are available for download from our digital library.

EDGE technical documents


The most recent versions of the EDGE technical catalogues feature a robust collection of updates and refinements. Just a few include:

  • New framing suites, like the MAX Centre Glazed
  • New window systems, like the EDGE Tilt & Turn and Multi-Locking Sashes
  • Updated diagrams and product details
  • Updated project photos across all sections, illustrating our systems in application
  • Louvres, fins, partitions, glazing adaptors and standard extrusions can now be found in the GEN catalogue
  • PDFs for individual suites are also available for download

We thrive on positive design evolution

The EDGE ranges are dynamic and constantly evolving. Along with our strategic schedule of new product development, many additions and changes featured in these editions come from collaboration with EDGE clients and stakeholders. The EDGE team remains nimble and creative in designing solutions to achieve the design intent of architects, facade engineers, and fabricators.

Details of the changes in the EDGE technical documents:

  • The previous four catalogues have been condensed into three: GEN now features louvres, fins, glazing adaptors and partition systems
  • “400 Centre Single Glaze” is available as a PDF download, as well as in the “EDGE Fast Find Index”
  • We reorganised the order of suites: 100 Centre, 150 Centre, 150 Offset, 100 Front, 150 Front
  • MAX Centre Glazed suite added
  • U-MAX 150 Centre Glazed suite added
  • U-MAX Sliding Window added (MAX coming in the future)
  • Tilt & Turn and Multi Locking features added to many suites, where they are compatible, within MAX and U-MAX (the development of tilt & turn and multi locking will expand in the future)
  • Using the “drained transoms” as a value add in other areas of 100 framing in MAX and U-MAX systems
  • New feature pages on Bifold doors and MAX and U-MAX Sliding Doors into suites, where compatible
