The EasyscreenTM Window System
Suitable for outside screen applications
Easyscreen is an aluminium framing system that is specifically designed for use with Altair Louvres. The system complements the full range of Altair features including Powerlouvre, Stronghold, IGLU, handle options and keylocks as well as fixed light bays, externally fixed screening*, security bars, sub framing system, bushfire compliance and a high strength design for cyclonic regions.

Easyscreen Window System 3D Models
Online viewing of 3D models is a relatively new technology. Please note the models shown below are rendered animations only. For more technical detail please view the CAD and BIM model section below. Viewing 3D models requires a fast internet connection and reasonably high speed computer processor. Viewing may not be possible on some older computers. We recommend Google Chrome for the best viewing results.

Easyscreen Window System Dimensions
Easyscreen Sub Framing
For projects where sub framing is the preferred installation method, Sub Framing is available for the Easyscreen Window System.
For Window heights ≤ 791mm:
Combined Window and Sub Framing height = Window height + approximately* 45mm
For Window heights ≥ 792mm:
Combined Window and Sub Framing height = Window height + approximately* 30mm
Combined Window and Jamb Angles width = Window Width + approximately* 24mm
*To be confirmed by installer. The above calculations include Window System and Sub Framing only. No additional materials or elements.
Easyscreen Security Bar System
Security bars are an effective barrier when the louvre is open, that unlike screens do not reduce any air flow.
Breezway has security bars available to fit 152mm (6”) blade heights with 16mm diameter solid aluminium bars fixed to the window frame to the outside of the blades and positioned to allow the window to open fully.
Altair Security Bars will have a moderate effect on views with 16mm solid bars and 124mm vertical spacings between bars.

Easyscreen Standard Heights
While Altair Louvre Windows can be manufactured in any size specified, the wind and water rating for the building project will affect the maximum allowable window height and bay width. Please refer to the Altair Product Performance Warranty for technical information.
For standard heights in the Breezway Easyscreen Frame please see the size chart on the right. For IGLU Louvre standard heights in the Easyscreen Frame please refer to the IGLU System page.
Off Standard heights are available but this will add cost and result in a fixed louvre blade to act as a filler piece. The sizes for Altair Powerlouvres in an Easyscreen Frame are also highlighted on the right.
Please note:
- Standard Heights are measured from the lowest visible metal to the uppermost visible metal of the frame and excludes fins.
- Off Standard Heights that are more than 5mm greater than or less than a Standard Height will have a top fixed blade to achieve the specified height. Off Standard heights that are within 5mm of a Standard Height will not have a fixed top blade.
- Some off-standard heights are unavailable when using the 102mm Altair Louvre Galleries with the Stronghold System. For the Easyscreen System these include: Standard Height + 26mm to Standard Frame Height + 36mm.
- Off-Standard frame heights between 6mm and 42mm above a standard frame height are not available for 152mm Powerlouvre in the Easyscreen Frame.
- Off-Standard frame heights between 1mm and 5mm below a standard frame height are not available for 102mm Powerlouvre in the Easyscreen Frame
- Off-Standard frame heights between 6mm and 44mm above a standard frame height are not available for 102mm Powerlouvre in the Easyscreen Frame.
- Refer to the product performance warranty on possible height restrictions for different blade types.
- Standard sizes will save money and improve lead times.
Easyscreen Widths
There are no standard Altair Louvre widths. The maximum width of a single continuous window with multiple bays is 4000mm. Maximum widths greater than 4000mm are possible through coupling two single continuous windows on site or at the window fabricator’s factory. The bay width may be affected by Building code rules. Please discuss with your Breezway fabricator and builder.
Altair Powerlouvre Windows
- Maximum width = 4000mm (frames over these dimensions will need to be coupled on site or at a window fabricator’s factory)
- Minimum bay width for 2-9 blade high windows = 400mm
- Minimum bay width for 10-18 blade high windows = 500mm
- Up to 6 galleries (bays) can be included in a single surround frame
- Combination louvre and fixed light bays are available
