Learn MoreCommon questions, answered.
Are awning windows good for ventilation during rain?
Yes — because the sash opens outward from the bottom, they can stay cracked open in light rain, letting in air while shedding water away from the opening.
How is an awning window different from a casement window?
Casement windows hinge on the side and suit taller openings; awning windows hinge at the top and suit wider openings, making them a common choice above kitchen counters or in bathrooms.
What glass and panel configurations are available?
Single, double, or triple-lite configurations depending on the opening width, with the same TEXGUARD coating and gasket sealing across all of them.
