Altair in Other Frames Standard Heights
For Altair Louvre Gallery standard heights please see the size chart on the right. Off Standard heights are available but this will add cost and result in a fixed louvre blade to act as a filler piece. Some off-standard heights are unavailable when using the 102mm Altair Louvre Galleries with the Stronghold System. For the Altair Component System these include: Standard Height + 19mm to Standard Height + 30mm.

Weatherstrip
Off Standard Height Galleries that are within 5mm of a Standard Height Gallery will not have a top fixed blade and will therefore require Standard Height Weatherstrip sets. Off Standard Height Galleries that are more than 5mm greater than or less than a Standard Height Gallery will have a top fixed blade and will therefore require Off Standard Height Weatherstrip sets.
Altair Weatherstrip does not require notching to accommodate the louvre gallery.
Weatherstrip, complete with seal, must be used in the head and sill to satisfy the Breezway Product Performance Warranty.
Weatherstrips to head and sill add 10mm to overall gallery height.
