Buying Guide

Having large windows in your home or office is a blessing when you want to brighten things up and let natural light into the room. They can help your space feel cheery and lively, and pick up your mood as well. However, one of the issues many people have with windows is that they can affect the temperature of your room. When it is cold outside, the room can feel chilly, and when it’s warm the room can overheat. In order to keep your room at a consistent temperature no matter the weather, you need thermal curtains.

Thermal curtains are made from thick fabrics like cotton or polyester and have multiple layers. They are designed to keep your room at a stable temperature by preventing air from escaping through the window or coming in through the window. This means that regardless of the weather outside, your room will be a comfortable temperature.

One of the biggest benefits of thermal curtains is the cost savings you see on your energy bill. If you use thermal curtains on all of your windows that get a lot of natural light or are exposed to wind, you may see a drop in your energy bill. In the winter months, you can find savings on your heating, while in the summer you can save on your air conditioning.

In addition to helping you control temperature, thermal curtains can also help to dampen sound. If you have rowdy neighbors or live on a busy street with a lot of traffic, using thermal curtains on those windows can help you get a little bit of peace and quiet. If you have trouble sleeping, thermal curtains can also help you relax by creating a blackout dark space. Many thermal curtains are so thick that they block out sunlight completely. This is ideal if you require pitch dark to sleep.

The Best Bang For Your Buck

ECLIPSE Light-Blocking Energy Efficient Thermal Curtains

Key Takeawy

You can't go wrong with these curtains, which are available in more than 22 different colors. The contemporary-style curtains are constructed from a durable polyester that is thick enough to block 99.9% of sunlight. They are easy to set up and add a layer of insulation to make your home more energy efficient.

What to Look For

  • Ensure the materials the thermal curtains are made from are thick and durable. Good options include polyester and cotton. In addition to the type of material, effective thermal curtains typically have two or three layers of fabric. Sometimes, there is a filler in-between each layer of fabric to offer additional thermal protection.
  • Consider what kind of hanging fixture you prefer. Grommets are a common modern option, but you can also find thermal curtains that are hung with hooks. Another style is a full enclosure where the curtain rod passes through a top pocket in the curtain.
  • While thermal curtains are typically chosen for their functional qualities, they are also a great way to showcase your decorative style. You can find thermal curtains in block colors or with different floral or geometric patterns. Decide whether you want something muted like a grey or beige or a pop of color with navy blue or pink.
  • Depending on the style of thermal curtains you choose and the aesthetic of your room, you may want to tie back the thermal curtains to let in sunshine during certain parts of the day. An easy solution is to use a wide ribbon in a complementary color to tie the curtain in place. Create a large bow or let the ribbon dangle as is.
  • Cleaning and maintenance for thermal curtains is easy. Most varieties can be cleaned in the washing machine and tumble dried on low heat. If needed, you can also iron thermal curtains after washing to get rid of any wrinkles or dents in the fabric. Be sure to read the care and maintenance instructions for your curtains first.

More to Explore

Ensure you pick the right sized thermal curtains for your window. The size you need depends on the look you want to create and the size of your window. If you want to create a traditional look, then the curtains should hang around four to six inches above the window frame and four to six inches below the window frame. Allow for another three inches on each side of the window frame. A modern look is longer, and the curtains should come down to about an inch off the floor, regardless of how long your window is. For a formal look, the curtains should hang close to the ceiling and pile down on the floor.
