When the summer sun is blazing, your home should be a cool, comfortable retreat. Unfortunately, windows can be one of the biggest sources of unwanted heat, causing indoor temperatures to rise and air conditioning systems to work harder.
We gathered some of the most common questions homeowners ask about staying cool and asked the experts for their best advice.
Q: How much of my home’s heat actually comes through the windows?
The Expert Answer: Quite a bit. One of the largest sources of heat gain in most homes is solar energy passing directly through the glass. Once sunlight enters your home and strikes floors, furniture, and walls, it converts into heat and becomes trapped indoors. This greenhouse effect can significantly increase indoor temperatures and energy costs. Addressing your windows is one of the most effective ways to improve comfort during the summer months.
Q: What are the best window treatments for reducing heat?
The Expert Answer: If keeping your home cool is the goal, certain window treatments perform better than others.
Cellular (Honeycomb) Shades are considered one of the most effective options. Their unique design creates pockets of trapped air that help insulate your windows and reduce heat transfer.
Solar Shades are specifically designed to block UV rays, reduce glare, and limit heat while still preserving your outdoor view. Lower openness percentages generally provide greater heat protection.
Blackout Roller Shades with thermal backing offer excellent protection against both heat and sunlight, making them ideal for bedrooms and west-facing rooms that receive intense afternoon sun.
Thermal Drapes can also be highly effective, especially when paired with shades. They add another layer of insulation while enhancing the look of the room.
Q: Does the color of my shades or curtains make a difference?
The Expert Answer: Absolutely. Color plays an important role in heat management. Dark colors absorb more solar energy, while lighter colors reflect more sunlight and help keep interiors cooler.
During the summer, lighter shades such as white, cream, and soft neutrals are often the most effective. If you prefer darker window treatments, consider products with a reflective or light-colored backing facing the window.
Q: Do I have to block all natural light to stay cool?
The Expert Answer: Not at all. The goal is to manage heat, not eliminate daylight.
Solar shades are a great solution because they reduce heat and glare while still allowing natural light into the room. Light-filtering cellular shades offer a similar benefit, creating a soft glow while providing insulation.
Another smart strategy is layering. A light-filtering shade can be used throughout the day, while heavier drapes can be closed during the hottest afternoon hours when sunlight is strongest.
Q: What are your top tips for staying comfortable during a heatwave?
The Expert Answer: The way you use your window treatments is just as important as the products you choose.
- Follow the sun. Keep shades or drapes closed on windows receiving direct sunlight. East-facing windows benefit from morning coverage, while west-facing windows should be covered during the afternoon.
- Keep hot air outside. If it’s hotter outdoors than indoors, keep windows closed. Open them only when outside temperatures drop in the evening or early morning.
- Consider motorization. Automated shades can be programmed to close during peak sunlight hours, helping maintain a comfortable indoor temperature even when you’re away.
The right window treatments can improve comfort, reduce glare, protect furnishings from UV damage, and help lower energy costs throughout the summer. A few strategic upgrades can make a noticeable difference in keeping your home cooler and more enjoyable all season long.
