Blackout Curtains vs. Thermal Curtains: Which is Right for You?

Blackout Curtains vs. Thermal Curtains: Which is Right for You?

Picking the right pair of curtains for a room can significantly affect the space’s overall aesthetic appeal. Curtains bring warmth, comfort, and style to your home whilst being functional.

Two popular curtain options are blackout curtains and thermal curtains. They both have distinct and specific characteristics that distinguish them from ordinary curtains.

The Mill Shop is here to showcase both types of curtains, their benefits and drawbacks, and help you choose what’s right for you.

Blackout curtains


  • They block out light, making them ideal for bedrooms and spaces that need complete darkness. Blackout curtains can significantly improve sleep quality by preventing early morning sunlight from disturbing one’s rest, making them the ideal choice for children’s rooms and nurseries.
  • The thick material can help to reduce noise infiltrating from the outside, creating a quieter environment for relaxing.
  • Blackout curtains can help reduce the heat inside your home during the summer by blocking out sunlight. They eliminate the need for large fans, which use energy and increase your bills.


  • Blackout curtains made of thicker material suit only some decor styles.
  • They are great for light blocking but don’t always have thermal properties.

Thermal curtains


  • Thermal curtains provide superior insulation, helping keep your home warmer in winter and cooler in summer, increasing energy savings and comfort.
  • Like blackout curtains, thermal curtains can help reduce noise from the outside due to their thick fabric and insulating layers.
  • They are available in various styles, colours, and patterns, making it easy to find a design that complements your home.


  • Whilst they provide excellent insulation, they don’t block out light like blackout curtains do.
  • They can appear bulky to some people who may be used to having voiles or lighter curtains at their windows.

Blackout thermal curtains

Blackout thermal curtains offer the ideal solution for those wanting to mitigate some of the drawbacks and enjoy the benefits of both blackout and thermal curtains.

Many of our thermal curtains at The Mill Shop also have blackout properties, combining light-blocking capabilities with thermal insulation.

These curtains can enhance sleep quality by keeping your room dark and at a comfortable temperature.

By being both light-blocking and thermal, they can significantly reduce your energy bills throughout the year. The thick insulating material will help to minimise noise, ensuring a serene atmosphere.

With The Mill Shop, you don’t need to worry about cost. While many believe that thermal blackout curtains can be expensive, we always try to be competitive when it comes to pricing. You must also consider the energy savings and enhanced comfort that justifies the initial investment.

What to consider before ordering your curtains

When deciding between blackout, thermal, or blackout thermal curtains, take into consideration the following:

  • Their purpose: If complete darkness is crucial, blackout or blackout thermal is the way to go. However, if temperature regulation is your main concern, thermal or blackout thermal are more suitable options.
  • Suppose you’re decorating on a tight budget. In that case, it’s essential to consider that while buying cheaper curtains may be appealing, the long-term energy savings thermal curtains can provide may outweigh the initial cost.
  • Make sure thicker curtains are what you’re looking for. You can style them with sheer curtains or nets for the best of both worlds.

Carefully evaluating these factors will help you make an informed decision and ensure you get suitable curtains for your home. Whatever option you choose, investing in quality curtains can significantly improve your living environment, contributing to better sleep, energy savings, and overall comfort.
