Search for a thermal curtain with at least two layers, triple-woven fabric, and blackout functionality to block out light and even noise. If you can’t find one, you can always have a Custom Made Curtain.

Even if the material used to make thermal curtains is essential in terms of how effectively they insulate the windows in your house, you must also consider other aspects like size, noise reduction, and aesthetics. This article will assist you in selecting the most delicate thermal curtain for your room.

The Advantages of Owning Thermal Curtains

The use of thermal curtains has several advantages. These curtains, with their many layers of cloth, offer an additional layer of insulation to your windows, saving you money on your energy costs.

The similar triple-layer construction that keeps cold air out and warm air in during the winter, or conversely in the summer, also reduces outside noise, providing a more tranquil atmosphere within your house.

Thermal curtains are also excellent at blocking out light. Darker curtains will effectively block all sunlight, enabling you to sleep in on those sunny weekend Sunday mornings. This thick material also ensures complete seclusion in bedrooms.

Thermal curtains protect your windows, enabling you to conserve energy while blocking sunlight, dampening outside noise, and providing the most privacy.

What to Consider In Choosing Thermal Curtains


Thermal curtains come in various styles, including essential classic curtains, Roman shades, hobbled shades, balloon shades, and side-draw shades, to mention a few. Thermal curtains are made out of insulating padding sandwiched between two layers of cloth hung by a curtain rod, stopping air from entering the room via the window.

Large windows, French doors, and sliding glass doors benefit the most from side-drawn shades. This traditional stacking design allows Roman blinds and crippled shades to open and shut. Balloon shades work similarly, except they collect the curtains as they ascend. Unlike traditional blinds, Roman and balloon shades are made of thick padded cloth that acts as an insulator.


Thermal curtains are available in various widths, varying from 36 inches to 52 inches and lengths extending from 54 inches to 108 inches. Curtains must be sufficiently large to cover the whole window frame to insulate effectively.

Aside from that, the size you choose is determined by the aesthetic you wish to create. Install the curtain rod for a classic appearance. Do it in the curtain drapes from 6 inches above the top of the window frame to approximately 3 inches under the base of the frame.

The curtains should typically reach 3 inches over either corner of the window—mount the rod near the ceiling for a contemporary look. Allow the curtains to stretch approximately 1 inch over the floor. You can also lay it on the floor to produce a puddled appearance.

If you use blinds or shades, make sure they fit firmly within the window frame to avoid air from escaping around the corners.


Insulated curtains, like regular curtains, are available in a broad range of materials, like cotton, polyester, silk, microfiber, and even velvet. Polyester and microfiber are the best materials for thermal curtains because they repel moisture, which may accumulate in the air trapped beneath the curtain and the windowpane.


While insulated curtains may conjure up images of ugly window coverings seen in cheap hotel rooms, they are available in a broad range of fashionable colors and designs. These curtains are more than just practical; they have appealing grommets and cuts that enable you to create conventional, contemporary, and classic appearances.

Noise Reduction

Thermal curtains may decrease noise in your house by up to ten decibels. The multiple layers of fabric in an insulating curtain not only reduce heat loss in your house but also absorb sound waves. This works in both directions, muffles the sound of your neighbor’s barking dog or crying kids while also muffles your loud music. 


Thermal curtains insulate by using several layers of material. The insulating layer comprises a heat-resistant substance such as foam, felt, thick cotton batting, or flannel in the middle layer. A thermal curtain must contain at least two layers, preferably three. They should also utilize blackout technology, which blocks up to 90% of light, for optimum insulation in the summer.

Insulation is assessed using the R-value, whether it is the insulation in your room walls or thermal curtains. The greater the R-value, the stronger the material’s insulating properties.

The R-value of a material varies from 0 for open-air to 60 for attic insulation. Windows has an R-value as well. Single-pane windows have an R-value of one, while Energy Star-rated windows have an R-value of three. When correctly fitted, an insulated curtain may raise the R-value of a window to as high as 6.


Particular curtains are machine washable, making them simple to keep clean. You may even dry several thermal curtains in the dryer. Others need a trip to the cost of dry cleaning. To prevent harming your curtains, always follow the supplier’s cleaning recommendations.
