AC-35: 35mm Awning / Casement

Envirotech Façade Solutions has started our design process with a blank sheet. Instead of short cutting the process and utilisingthe traditional shop-front and window suites of the 1960s, EFS has designed a range of commercial suites to suit todays’ requirements, standards, codes and architectural trends.


The AC-35 awning systems are designed to be used in most commercial and semi commercial applications. These suites also cater nicely to those looking for a more robust, cleaner looking design option for upmarket housing applications. The AC-35 offers the added benefit of being capable of taking a 25mm IGU when higher performance is required. These design inclusions translate to designers and fabricators being able to glaze thicker and therefore larger pieces of energy efficientglass than many of the other suites currently on offer to the market.


This new design integrates with all the EFS commercial suites from the 101.6mm, 150mm through to the 200mm framing as well as our high performance curtain wall systems.


From a performance perspective, these features mean that designers need not compromise their designs in order to achieve performance requirements for thermal, acoustic, structural and water ratings.


Please contact our friendly sales or technical staff for help with your design requirements and if required, we can help customise a solution for your next project.
