Best Curtains for Blocking Heat

Window treatments can be an easy heat-reducing solution. Here are four types of curtains that'll help you beat the heat.


1. Thermal-Insulated Curtains

Thermal curtains are lined with a thin layer of material that is designed to reflect heat. That's why they're considered the most effective heat-blocking curtains! The best part? These curtains also help lock-in indoor temperatures, so your space will stay cool and refreshing during the summer and nice and warm during the winter.

2. Breathable Natural Fiber Curtains

Linen and cotton curtains are two natural fiber options known for their breathability and cooling properties. Both linen and cotton curtains allow air to circulate while blocking sunlight, allowing your room to stay cool and airy. Trying to decide between the two? Linen curtains are known for their natural texture and muted color palettes. In contrast, cotton curtains can be manipulated to take on bright colors or patterns. It all comes down to your preference.

3. Sheer or Light-Colored Curtains

Sheer curtains are a good option for people who want to let in some light but limit the amount of heat and direct sunlight that gets through. These are usually made of translucent, lightweight fabrics. You can also opt for white or pastel solid-colored curtains because lighter colors don't absorb heat like darker colors do.

4. Light-Colored Blackout Curtains

Blackout curtains don't just block sunlight – they can also be used as thermal-insulating curtains! Be sure to choose a light color like white, beige, or pastels to ensure that they reflect the light instead of absorbing it. When shopping on Wayfair, you may notice that most blackout curtains with thermal-insulating properties have lighter color options.

Tips for Choosing Curtains That Block Heat

Here are some additional tips and best practices to consider when choosing heat-blocking curtains for your home.


1. Add a Thermal Lining to Existing Curtains

If you have curtains that you love, you can always add a thermal lining to enhance their heat blocking properties. Thermal lining is a thin layer of material that is designed to reflect heat. It can be added to any type of curtain, and it will make them even more effective at blocking heat.

Curtains that reach all the way to the floor will help to create a barrier against heat from the outside.
