Sizes

Altair® Louver Windows are custom manufactured to order, meaning there is a wide flexibility in sizes available.

Widths

 

There are no standard Altair Louver widths.

The desired window width can be achieved through multiple louver bays. When determining the bay widths possible a rule of thumb is the higher the wind and water performance required, the shorter the blade should be.

The bay width may be affected by Building code rules. Please discuss with your Breezway Dealer and builder.

Heights

 

Standard heights do exist and are based around the chosen blade size. Altair Louver Windows use blades that are either 4″ or 6″ high. Multiples of these blades give standard window heights. The type of window frame chosen will also affect the standard heights. Off Standard heights are available but this will add cost and result in a fixed louver blade to act as a filler piece.

For standard heights in Breezway frames see the size chart below. The sizes for Altair Powerlouver in Easyscreen frame are also shown below. Note: There are no changes to standard heights when using Altair Louvers with the Stronghold System in an ios or Makani Window System.

Proprietary frame height will be based on the sizes for Altair Louvers with weatherstrip below, plus an allowance for the outer frame type chosen. This is best discussed with your window fabricator and builder.
