8 Best Window Types For Hot Climates
1. Double-Pane and Triple-Pane Windows
These windows consist of two or three layers of glass with an insulating gas (like argon or krypton) sealed between the panes. They are also known as insulated glass units (IGUs).
Why They're Ideal:
- The multiple panes and gas layers significantly reduce heat transfer to keep your home cooler in the summer.
- They improve energy efficiency by reducing the use of air conditioning.
- Triple-pane windows provide even greater insulation for areas with extreme heat.

2. Low-E Glass Windows
Low-E (Low-Emissivity) glass has a special coating that reflects infrared heat while allowing visible light to pass through.
Why They're Ideal:
- Reflects solar radiation, reducing indoor heat gain and glare.
- Blocks harmful UV rays to protect your furniture and flooring from fading.
- Helps maintain a comfortable indoor temperature while reducing cooling costs.
3. Casement Windows

Casement windows are a classic choice but will require space for opening.
Hinged on the side, casement windows open outward like a door, allowing for maximum ventilation.
Why They're Ideal:
- Excellent for directing cool breezes into the home.
- Their tight seals, when closed, prevent air leaks and improve energy efficiency.
4. Awning Windows
Awning windows are hinged at the top and open outward, creating a slanted opening.
Why They're Ideal:
- Let air in while protecting against rain or direct sunlight.
- Work well in areas where airflow is needed without compromising energy efficiency.
5. Vinyl Frames
Vinyl frames are made from PVC and often include insulation to enhance thermal performance.
Why They're Ideal:
- Resistant to heat and UV rays, which makes them durable in sunny climates.
- Require little maintenance and do not warp or fade over time.
6. Fiberglass Frames
Fiberglass frames are strong, durable, and can be filled with insulation for better thermal performance.
Why They're Ideal:
- Highly resistant to warping or expansion due to heat.
- Provide superior insulation compared to aluminum or wood frames.
- Require minimal maintenance.
7. Skylights
With operational skylights you can vent hot air trapped near the ceilings.
Why They're Ideal:
- Allow hot air to escape during evenings while letting in natural light during the day.
- Can be covered during peak sunlight hours to make the space more comfortable.
8. Bay and Bow Windows
These windows project outward from the home and consist of multiple panels.
Why They're Ideal:
- Add aesthetic value while allowing natural light into larger spaces.
- When paired with curtains or shutters, they can help control sunlight exposure effectively.
Additional Window Features For Hot Climates
1. Low SHGC (Solar Heat Gain Coefficient): Limits the amount of solar radiation entering the home to keep interiors cooler.
2. Shading Devices:
a. External shading, like awnings, louvers, or blinds, blocks direct sunlight before it hits the glass.
b. Fixed horizontal shading (e.g., pergolas) for north-facing windows and adjustable shading for east- and west-facing windows.
3. Reflective Window Films: Reflect sunlight and reduce glare to improve indoor comfort.
4. Blackout Curtains: Block sunlight during peak hours to reduce indoor heat gain.
5. Proper Orientation:
a. South-facing windows for minimal direct sunlight.
b. Smaller windows on sun-exposed sides to limit heat ingress.
