Blockout or Triple Weave…What is right for you?

When choosing between blockout and triple weave curtains, consider your priorities—both offer benefits, but your choice depends on whether light control, insulation or machine washable is your main goal.

When the weather is cooler, it's time to look at ways you can insulate your home, keeping the warm air in and the cold chill out.  One of the most common questions we get asked is, "What is the difference between blockout and triple weave curtains?" 

Both types of curtains have similar qualities, however, there are some differences that you may want to keep in mind while shopping around for the perfect window coverings for your home.

Here is everything you need to know about choosing between blockout curtains and triple weave curtains for your space.

What are the Pros of Triple Weave Curtains?

  • Triple weave curtains help keep light out thanks to the three interwoven layers including a light-blocking layer
  • Triple weave curtains will effectively help control the room temperature. Warmth is contained in the room during the winter, while unwanted sunlight and heat is reflected out of the room during the summer months.
  • They will likely lead to lower energy bills! What’s not to love about being energy efficient!
  • All of our triple weave curtains are machine washable and naturally mould-resistant

What are the Cons of Triple Weave Curtains?

  • Some light can still filter through triple weave curtains – if you need a window covering to completley block out light, triple weave curtains may not be the right fit for your space. If you have chosen a triple weave curtain but still require further insulation, opt in for an attachable blockout lining or lining curtain on a separate track.
  • They are not as energy efficient as blockout curtains. Heat can still escape through them.

What are the Pros of Blockout Curtains?

  • Blockout curtains, also known as blackout curtains, block out light from entering a room, creating a darker, more restful space at any time of day.
  • They will provide great heat reduction properties – less heat will escape through your windows in the colder months, and in the warmer summer months your room will be cooler.
  • Blockout curtains have no separate linings.

What are the Cons of Blockout Curtains?

  • Blockout curtains, as the name suggests, completely block out light. This may not be suitable for some rooms, so keep this in mind when choosing this type of curtain.
  • They are not machine washable.

In summary, the right curtains for your home will essentially come down to your personal preference and priorities. If you are looking for a curtain that will completely prevent light from entering a room, we recommend blockout curtains. If you are looking for dim-out curtains and you do not have to overly insulate your windows, triple-weave curtains may be the right choice. If you are still unsure, our Design Consultants are here to help.
