    What is a Thermal Curtain?

    When it comes to warming up your home without breaking the bank, thermal curtains are often the best way to go. Thermal curtains serve as an added layer of insulation in your home that makes it more energy efficient. Since the glass on windows tend to be poor  insulators, thermal curtains are able to fix that. 

    Installing thermal curtains in your home also decreases the amount of money you spend on your energy bills each month because of their ability to reduce the amount of heat lost in the cooler months and reflect heat in the summer. 

    When it comes to sleeping well temperature is a key contributing factor.

    What are Thermal Curtains Made Of?

    Typically, thermal curtains consist of a double- or triple-layered heavy fabric with an added backing of insulate material. Plus, there’s often a polyester-film vapor barrier worked in there as well. 

    Thermal curtains are generally made from materials including wool, polyester, or cotton, and are coated on the window side with acrylic foam or aluminum. This extra coating protects you from UV rays.

    Can Thermal Curtains Be Washed?

    While some thermal curtains are machine-washable, it’s often recommended that you hand-wash them instead. To do so, hand-wash them in cold water, making sure not to let the thermal coating latch on to itself. While you wash them, make sure not to rub or wring the curtains as you could damage the material.

    In order to dry the curtains, gently squeeze them to remove excess water and hang them dry using the curtain hooks. Do not use clothespins to hang them and be sure not to fold the curtain over the line to hang dry.

    Do Blackout Curtains Insulate Like Thermal Curtains?

    Most of the time, thermal curtains are also blackout curtains, meaning they’re insulated like typical thermal curtains. In cases where curtains aren’t thermal, the blackout curtains will insulate, just not as well. 

    This is because the blackout curtain’s main purpose is to keep light out of the home, rather than insulate, while thermal curtains are solely for insulation purposes. But, both blackout and thermal curtains insulate in one way or another.

    What is the Difference Between Thermal and Blackout Curtains?

    One of the biggest differences between thermal and insulated curtains are their purposes. Blackout curtains serve to keep out light, while thermal curtains serve to keep cold air out and warm air in. When it comes to deciding which suits your home, it depends on what your biggest problem is. 

    If you’re home is already well insulated but you want to keep natural light out, go with blackout curtains. But, thermal curtains are the better choice if you have drafty windows. In the end, most thermal curtains will work as blackout curtains but most blackout curtains won’t work as thermal curtains.

    Things To Look For In Thermal Curtains

    There are tons of options available when it comes to finding the best thermal curtains for you. But, before committing to a purchase, there are a couple of things to look for throughout your shopping process.

    The Amount of Layers

    When it comes to finding the best thermal curtains, be sure to evaluate how many layers the curtains have. Single-layered curtains only provide thick fabric rather than an insulating layer, making them have poor insulation abilities. Instead, look for curtains with a foam core that look and feel extra durable.

    The Type of Material

    While layering is key for thermal curtains, so is material. There are multiple materials used for the lining of thermal curtains, each with their own benefits. There’s blackout lining, which gives good insulating value and light doesn’t pass through, as well as flannel-backed lining that’s proven to provide medium insulation and allows some light to pass through. 

    If you’re looking for a full blackout experience, the French blackout lining creates a full blackout effect and contains a highly insulating drapery treatment.

    Curtain Header Styles

    It’s important to make sure the thermal curtains you choose function properly, but it’s also important that they add to the look of your home. There are multiple types of header styles and the one you choose should fit with the look you’re trying to create. 

    Rod Pocket

    Rod pocket headers allows for the most versatility in the look of your thermal curtain, as you can add your own rings for a customized touch. Curtains that are hung this way have a casual and simple look.

    Grommet

    A grommet header is one of the most common curtain styles, as it allows for the opening and closing of the curtain to be simple and easy.

    Tab Top

    Tab top curtains feature exposed loops (tabs) on the fabric that are drawn through a curtain rod. These curtains are most popular in country style homes.

    Pinch Pleat

    Pinch pleat curtains are a common and decorative choice of heading that draws together lots of fabric for a fuller look. The header is typically tightly bound and stitched at the top and contains elegant folds flowing from the top down.

    Conclusion

    All in all, thermal curtains are the way to go if you’re looking for a cheap way to keep your home warm in cooler weather. Plus, there are thermal curtains that work for all seasons, making them a worthwhile purchase. Insulated curtains come in all different styles, colors, and fabrics, making them both a stylish and effective addition to your home.
