. By reducing the need for artificial cooling and protecting windows from damage, Window Awnings support a future that’s more comfortable, energy-efficient, and resilient to extreme weather.
How Awnings Help Cool Your Home
In hot weather, windows become major heat sources—especially those facing south or west. Sunlight pours in, heating up rooms and overworking fans or AC (if you have it). Awnings offer passive solar cooling by shading windows and blocking direct sunlight before it reaches the glass.
According to the U.S. Department of Energy, awnings can reduce solar heat gain by 65% on south-facing windows, and 77% on west-facing windows. [1]
This not only cools your home naturally but also protects furniture and flooring from UV damage. Well-placed awnings also let in low winter sun, making them effective year-round in passive solar design.
Types of Awnings
- Fixed Awnings: Permanent structures that consistently block sunlight. Simple and effective for sunny windows.
- Retractable Awnings: Can be pulled in or out depending on the weather or season. More adaptable, but usually more expensive.
- Clamshell Awnings: Durable, hinged panels (often aluminum) that can be propped open for shade or dropped fully closed during storms.
Why Clamshell Awnings Deserve a Comeback
Clamshell-style awnings are a practical choice for anyone in storm-prone areas—or for those off-grid who want a multi-use, no-power-needed solution. When closed, they form a protective shell over the window, guarding against extreme weather.
Tips for DIY Installers
- Angle awnings to block the high summer sun but allow in low winter sunlight.
- Choose durable, weather-resistant materials like aluminum, treated wood, or fabric with UV protection.
- For clamshells, check salvage yards or second-hand stores—they’re often available for cheap and easy to repaint.
