They are taller than they are wide, with sizes up to 42″ wide × 90″ tall. Awning windows are hinged at the top and open outward from the bottom excellent for bathrooms, laundry rooms, and above counters where rain protection during ventilation is important. They are wider than they are tall, with sizes up to 66″ wide × 48″ tall. Both types feature triple-layer compression seals for exceptional airtightness when locked.
