What Are Thermal Curtains? Choices Of Thermal Insulated Curtains For Your Home

Simply stated, thermal curtains, or thermal insulated curtains are curtains that keep the heat out in the summer, and equally important, they keep the heat in come winter cold.

In the old days, people used very heavy drapes, often velvet drapes made of heavy cotton or silk. Only royalty could afford them.

Today, the invention of plastic materials with insulating properties is allowing a much less heavy yet still thermally insulating curtain construction. Many of these materials you can even find at Walmart at a really good price. You will find faux-suede thermal insulated curtains, faux-silk thermal insulated curtains, even beautiful white velvet curtains. Any of these will help you save on heating costs.

Here are four of our reviews of different types of thermal curtain panels:

Best Thermal Curtains At Target, Walmart, IKEA, Lowes And AmazonBest Thermal Curtains At Target, Walmart, IKEA, Lowes And Amazon. It is amazing how these top North American retailers offer such completely different choices of their top thermal insulated curtains. None of them suggests the same top thermal curtain choices. It is also true that their product descriptions are rather short and generic. There are no color considerations mentioned for best insulation, no size recommendations, and no material preferences mentioned.

This makes it difficult to pick the right heat blocking curtain for your home.

That is why we provide our own opinion on thermal window treatments based on simple physics. Our reviews which will hopefully give you an additional guidance of what to look for to get a perfect set of thermal curtains for your rooms.

Thermal Curtain Linings Boost The Insulating Power Of Your Curtains

What do you do in the winter when it becomes extra cold and you have to go out into the cold? You add an extra layer of clothes! Same thing with thermal curtain linings. You can add an extra layer of curtain thermal lining to every single curtain out there, even the one that is already labeled thermal or energy efficient. Since windows are the biggest heat sink in your house, every extra layer of thick curtain lining will directly influence the temperature in your room, and, at the end of the month, your utility bill will go down. We find that, thanks to the fiber technology, thermal insulating curtain lining does not have to be all that thick after all (think Thinsulate!).

Two most popular thermal linings, Thinsulate Curtain Liner and Thermalogic Curtain Liner

Thermal Window Coverings - 3M Thinsulate Insulating Curtain Liner PairThinsulate Thermal Curtain Linings For Winter And Summer: This is a lining that fits any curtain style at all and increases thermal blocking on every window in the house. Thinsulate fabric, as the name reveals, is a 3M product that was designed to take advantage of micro fibers.  Micro fibers are ten times thinner than usual. This then provides super small air pockets that provide excellent thermal insulation. You will frequently find Thinsulate in gloves, caps, and thermal insulated clothes. And now Thinsulate is used to make Thinsulate curtain thermal lining.  The lining thus becomes relatively thin, flexible, and easy to work with. Best, Thinsulate curtain linings can be attached to most curtains via the variety of hooks. They can even be hung in parallel using a double rod.

Heat Reflecting And Heat Reducing Window Films

Thermal insulated curtains and thermal curtain linings is not all you can do to keep your biggest heat sink in the house, your windows, thermally insulated! Heat reflecting and heat reducing window films are a little known secret of further decreasing your heating costs in the winter, and AC costs in the summer. This technology was for the most part only used on windows of large corporate offices. However it is now available for house owners and apartment dwellers alike.

You will be surprised to find such a wide variety of window films that will all help you. Some create air pockets between the window and the film for insulation, others use the reflectivity of a metal (such as platinum or titanium) to reflect the heat and reduce heat losses that way. Heck, you could even use all three types of thermal window treatments below if you are a heat loss freak. Or you may just find that one of them will be quite enough. Don’t be afraid to experiment!

We review three ways you can use a heat reducing window film. These are: Indoor Gila Heat Control Platinum Window Film, Outdoor 3M Heat Reflective Window Film, and Duck Brand Heat Blocking Window Film. Check them out below.
