If you struggle with rooms that overheat or aggressive sunshine, the best thermal curtains to keep heat out are a smart investment, and can be a real lifesaver during sweltering summers or in consistently hot climates. In fact, they can even save you money by keeping your room colder without you having to purchase an air conditioner or fan.
While, yes, thermal curtains can reduce light by up to 90% and insulate against heat, it's important to note that not all thermal options are alike. For the best insulation, look for a thermal curtain that has at least two layers, triple-woven fabric, and blackout technology to eliminate light and even noise. And while it may initially seem like the bigger the price tag, the better the quality, that's not actually the case. There are plenty of high-quality curtains that are totally budget-friendly.
And, as you shop, don't forget to keep in mind the size and length of your window. Length will be particularly important, as you want to get heat-resistant curtains that match your space requirements, and many of the options on this roundup feature curtains that come in a variety of lengths and size options.
