10 Best Window Coverings To Keep Heat Out 2026 in the United States

The AOSKY Cordless Roller Shades are designed to block out sunlight completely with their blackout fabric made of 100% polyester and a thermal insulated coating. This material feels soft and is durable, making it easy to clean and effective in reducing heat loss or gain through windows. The white color helps keep rooms bright while still blocking UV rays, which protects furniture and reduces energy costs. The cordless design adds safety for homes with children or pets and allows smooth, adjustable positioning thanks to the spring system, which has been tested for durability.

Installation is supported by included hardware and clear instructions, including videos, helping most users set it up without hassle. However, the fabric width is slightly narrower than the overall shade size, so precise measuring is important to ensure full window coverage. The product is not water-resistant, so it’s best suited for indoor use in places like bedrooms, offices, or living rooms rather than humid areas. Adjusting the speed and stop positions of the shade requires manual screw adjustments, which might be a bit fiddly for some.

These roller shades provide strong insulation, UV protection, and a neat cordless design that fits well in many home or office settings where blackout and heat control are priorities.

The GoDear Design 99.99% Blackout Adjustable Sliding Panel Track Blinds are designed to provide superior light blocking and insulation, making them a great choice for those looking to reduce heat and maintain a comfortable indoor temperature. Made from a natural woven blend of 40% paper and 60% poly, these blinds offer a modern and sophisticated alternative to traditional vertical blinds. They are highly effective at blocking up to 99.99% of sunlight, which helps minimize heat loss in colder months and reduces energy costs throughout the year.

Additionally, the blinds offer enhanced privacy, making them suitable for bedrooms, nurseries, media rooms, and large windows. They also protect furniture and floors from sun damage and fading. The adjustable design allows for a custom fit with a track that can extend from 45.8 inches to 86 inches wide, and the panels can be trimmed to fit your specific needs.

The blinds are easy to install with multiple mounting options (wall or ceiling) and include a cordless system, making them safe for homes with children and pets. However, it's important to note that the blinds are not water-resistant and the actual color may vary depending on your display. The product requires assembly, but it comes with all necessary hardware and detailed instructions. They are ideal for anyone looking to improve insulation and privacy in their home.

These cordless blackout window blinds are a good choice if you want a simple, damage-free way to reduce heat and sunlight in your home. Made from a thick, non-woven fabric, they offer waterproof, dustproof, and breathable qualities, which help with insulation and long-term use. The cordless design is safer for homes with kids and pets, and the blackout feature plus UV protection effectively blocks out sunlight and helps keep rooms cooler.

Installation is quick and easy, using strong self-adhesive tape—no drilling or tools needed—and you can cut the blinds to fit your window size perfectly. They come with clips to adjust the height, adding flexibility. The blinds come in several colors, with darker shades like grey and black providing better blackout and UV resistance, while lighter colors allow some light through.

Since these are made of paper-like fabric, durability might be less than heavier materials like vinyl or fabric blinds, and they require careful spot cleaning. Their insulation won’t be as strong as thicker or multilayered blinds. For temporary or light-duty use in bedrooms, nurseries, or kitchens, they work well, especially if you want a no-fuss, removable solution that doesn’t damage your walls or windows.
