Best Thermal Curtains

Do you need to buy thermal curtains?

To answer this question, consider a few things first.

The best thermal curtains are ideal for rooms which have huge exposure to sunlight. Their thickness allows them to dampen outside noises, hence making them equally perfect for rooms with loud sound exposure. Finally, if your home is centrally heated or cooled, thermal curtains, by denying air any inlet or outlet, will save both energy and money.

The Best Thermal Curtains

NICETOWN Thermal Insulated Grommet Blackout Curtains


For those people who want to have more control over the temperature and lighting of their rooms, the Nice town curtains are a must have. Even without a liner, these curtains are able to block 85-99% of light. Such variance in heat blockage draws from their color as light-shaded curtains block less light than their dark-colored counterparts.

The fact that they only use polyester in their fabrication enables these curtains to block outside noise. Add to it the triple weave fabric which they use – one which keeps both the winter chill and summer heat out, and these fabrics block all of energy, noise, and sunlight.

How exactly does the triple weave technology functions? The secret lies in the three layers. With a heavy density microfiber on top, which is supplemented by a high-density black yarn in the middle followed by another layer of the fabric at the bottom, the triple weave technology protects your privacy and prevents your room’s heat loss at the same time.

Lastly, if the last curtains in your room required constant ironing to look luxurious, these thread trimmed curtains are fabricated to be wrinkle-free. A simple steam-clean would be enough to take wrinkles off them. That said, they are machine washable as well if the dirt levels go out of control.

User Critique

These curtains aren’t lined which means if you choose light colors such as gray or pink, they won’t be able to blackout light.

PROS
  • Wrinkle-free and thread trimmed
  • Triple Weave Fabric to save energy loss
  • Dark colors block up to 99% of light
  • Machine washable
CONS
  • It is very loud.

Amazon Basics Room Darkening Thermal Insulating Blackout Curtain


For those of you who are in the market for only the best insulated curtains, you cannot afford to miss the ones from Amazon Basics. Made from 100% polyester, they will give you an incredibly silky and soft feel to touch. They come in various designs and lengths so selecting the drapers which complement your room won’t be a problem.

Just like their counterpart from Nice Town, the Amazon Basic Curtains use the triple-weave fabrication technology in their fabrication. Using this technology means that these fabrics will not only block light but also dampen outside noises.

An added benefit which these curtains are bound to provide is their role as an energy-saving barrier. The combined efforts put together by the triple weave technology and polyester fabric means that while in summer they would keep out, the reverse would happen during the winter season.

Lastly, if you want to hang these curtains in the kids’ room, rest assured that they are eco-friendly and contain no chemical coating. Rather, only polyester was employed which means the Amazon Basics won’t smell either.

RHF Wide Thermal Blackout Patio door Curtain


If you are willing to spend a bit over the odds, the RHF wide Thermal Curtains might suit you just right. For, there are reasons why they cost more than other thermal curtains in this review.

For starters, RHF have decided to forego the more in-fashion triple weave technology in favor of their very own sandwich technique. The results of this choice are there for all to see as the sandwich technique enables these curtains to keep out up to 99.8% of sunlight.

Energy saving is another area where these curtains are worth the extra price. The increased layer of microfibers, though they make the curtain heavy, allows it to block the heat transfer with ease. So if you have trouble paying the energy bills, these curtains are a godsend.

How Do Thermal Curtains Work?

Thermal curtains prevent the loss (or gain) of heat inside your room by keeping four types of heat loss at bay; namely: conduction, convection, radiation, and infiltration.

All these types of heat transfer flow one way – from cold areas to hot areas, and thermal curtains act as a barrier midway through their journey. They do so by providing insulation, which, in turn, comes from four protective films which every thermal curtain worth its salt needs to have.

These four layers are:

  • The outer layer – which is the first one – contains an inner lining to give the curtain its shape.
  • The second layer which is made up of high-density foam blocks sound and heat waves.
  • The third layer, which is known as the vapor barrier, prevents moisture from escaping.
  • Finally, there is that reflective film which makes sure that heat wanting to escape the room goes back in it.

When winter comes, these layers keep the heated inside air from escaping or being cooled. Conversely, on the arrival of the summer, the cooled inside air will not be allowed to either escape outside or being heated by contact with outside air.

Best Thermal Curtains Buying Guide

Yes, you may have selected the thermal curtain for your home from the list mentioned above, but you might still want to go through this buying guide. If nothing else, it will give you the information to make an informed decision before making the purchase.

Features That Are Important

For Light Control

If you want complete blackout in your room, consider investing in a thermal curtain which has a blackout lining. (Clue: these curtains will be the heaviest of the lot).

However, if you only want to limit the light exposure of your room, go for velveteen, velvet wool-blend or corduroy fabrics, as they provide maximum light control without making your room completely opaque.

For Noise Control

As you might guess, rooms which face the street or main road are the biggest recipients of loud noise. For such rooms, therefore, thermal curtains are NOT a luxury but a necessity.

Therefore, if you live in any such room, thermal curtains with deep pleats will come to your rescue. In addition to absorbing sound, deep pleats also improve the acoustic quality of your room.

For Heat Control

Heavy fabrics such as tapestry, velvet, suede, and damask are a must-have for rooms where drafts, particularly in the winters, sap the room’s heat through its windows.

If you find these fabrics to be expensive, consider a curtain which has an interlining. These curtains have additional blanked stitched between the lining and the curtain, hence providing better sound and heat insulation.

Color

Since your room gets a lot of sunlight – that’s why you are here, don’t you? – choose the color of the curtain carefully. Otherwise, sunlight will fade the curtain’s fabric in no time.

Therefore, if you ask us, we recommend avoiding bright colors – as they fade faster – and siding with the lighter ones. They might not add ‘style’ to your room, but light-colored curtains will certainly do their job for far longer than their bright colored counterparts.

Panels and Grommets

Especially true for people who live in a rented apartment, make sure your curtain offers more than one panel and grommets. In this way, no matter how many houses you change, you’d be able to install the same curtains in all of them.

Otherwise, with each house change, you’d have to spend extra on changing the grommets of your curtains.
