 Louvre Windows - Narrow Configuration
Narrow Windows

Tall, narrow windows are great for smaller areas within the home that require natural light and ventilation.

Size Restraints: The minimum width toughened glass blade is 300mm wide.  Louvre windows can achieve heights up to 3000mm high.

 Louvre Windows - Floor to Ceiling configuration
Wall of Louvres

A wall of louvres can maximise ventilation and outside views.

 Louvre Windows with Fixed Lite Configuration

Louvres with a fixed lite help frame the view while getting good air flow into the house.

Size Restraints: The maximum square meterage of a fixed lite window is 4m2.

 Louvre Windows above a door configuration
Above Doors

Place short, wide louvres above doors to allow hot, rising air to escape quickly.

Size Restraints: The maximum width per blade is 900mm wide with 152mm blades and 750mm wide with 102mm blades.  Often we can line up the mullions of the louvres to match the mullions of the sliding door for a visually appealing look.

Standard Sizes

For louvre windows, the height is an important factor.  Standard sizes are determined by the number of full blades.  The standard sizes for louvre windows are very different to other styles of windows and are different depending on the frame type and blade size you choose.

For non standard heights, an extension blade is used.  This is a small, non-operating blade (glass, aluminium or timber) to suit the rest of your blades or an aluminium infill if the blade is less than 40mm.

Non standard height windows attract a 10% surcharge to the cost of the frame.

Blade prices are calculated depending on the width of your louvre, so there is no standard widths for louvres.  You just have to conform to the size limitations of the product (generally about 300mm to 900mm wide per bay).

Natural Ventilation

Louvre windows allow ventilation throught the whole window area as they open twice as wide as other window types. They offer ventilation no matter which direction the wind is blowing, in comparison to casement or awning windows

You can also restrict the flow of breeze by only opening part of the window or angling the blades

Cross Flow Ventilation

To create cross ventilation, openings are needed on opposite sides of a room to allow fresh air to enter, flow through the room and then exit.

Internal Ventilation

Ventilation openings are often needed in internal walls as well as external walls.

Thermal Chimney Effect

Another good way to naturally cool a room is to place some louvre windows up high.  This is effective because rising hot air is able to escape the room throught the high up louvres, helping to keep the room cool.

Sealing

Louvres keep the weather outWindows and doors that seal tightly minimise the amount of air that can leak out of them, helping heating and cooling systems to run more efficiently.  Tight sealing windows avoid cold draughts in winter and even play a role in sound insulation.

Altair Louvre Windows provide tight sealing due to:

              • •  The living hinge design that resists water and air penetration between the clips and the channels.
              • •  An over centre locking mechanism which applies strong locking pressure to blades when fully closed.

Breezway’s Altair louvres have undergone extensive testing in accordance with the Australian Standards for Windows (AS2047) and are cyclone rated to ensure maximum wind and water performance.
