The short answer is: yes! The longer answer is that blackout curtains do indeed keep heat out of your home—but only to a certain extent. They will keep the majority of light out, which can help save money on your electric bill by reducing the number of lights you need on in order to see at night. They’ll also keep heat from seeping into your room from outside—it’s not just about blocking light, but also about blocking temperature.

If you live in a warm climate or have an older home, you might want to consider using blackout curtains as a way to help keep the heat out during the summer. You can find them at our online store Nicetown.com, but make sure that you buy ones that are designed for keeping heat out.
