Awning Double Glazed Windows

Awning windows are outward-opening windows that are hinged at the top and swing outward from the bottom. The design of these windows creates a small canopy that allows in fresh air while preventing light rain from entering internal spaces. The design also makes them highly energy efficient, as they shut tightly against the frame to seal out drafts. With double glazing, these windows incorporate two glass panes separated by an insulating gap of air or gas, keeping homes quieter, more comfortable, more cost-effective to keep cool and warm, and also more secure. 

Yes, compared to many other window styles, awning windows are highly energy efficient – even without double glazing, which increases the energy efficiency these windows deliver significantly. There are several reasons why awning windows provide high levels of energy efficiency, largely around the way that they seal when closed.

Awning windows feature a compression seal, which, when closed, involves the sash pressing tightly against continuous gaskets or weatherstripping. Combined with an airtight design in which a cranking mechanism and multi-point locks pull the window flush against the frame, and double glazing which features two panes of glass separated by an insulating gap of air or gas, and you have a window that provides exceptionally high levels of energy efficiency, as well as security – another important consideration for property owners.

Awning windows best suit rooms and areas that benefit from ventilation during light rain, or airflow above high walls and counters. This makes awning windows ideal for bedrooms and living rooms where they’re positioned high or above large high-level windows, bathrooms and en suites in which they’re installed behind the wall to let steam escape without compromising privacy, and kitchens in which they’re placed above the sink or counters where space is limited and/or reaching a sliding window can be difficult. 

Yes, you can open awning windows while it’s raining; however, there are some limitations. These include heavy storms and strong winds, which can blow rain sideways into the opening, and the opening angle – to prevent rain from entering, it’s advisable not to fully extend the opening to maintain the ‘canopy’ effect.  However, in mild rain conditions, awning windows are highly effective at allowing ventilation into interior spaces while preventing rain from entering. This is due to their top-hinged design, which creates a small canopy over the opening, combined with the angle of the window deflecting water so that rain falls and flows away from the window opening.
