Blackout Curtains

Block out heat with your windows!

How it works

  • Blocks light coming in from your windows. 
  • Reduces the heat coming in from your windows by up to 24 per cent! 
  • Keep the curtains closed when it’s hot outside to reduce the heat coming in
  • Keep the curtains open when it’s cool (especially at night) to let hot air to escape, and to prevent mould growth.


  • Energy Savings: Blackout curtains are cheaper to install than running an air conditioner, which can save you on energy costs in the long term. 
  • Privacy: Blackout curtains can block your space from outside view, giving you privacy. 
  • Sleep: Blackout curtains block out external light, promoting melatonin production in your body and giving you more restful sleep.


  1. Measure Windows: Use a tape measure and write down the dimensions of your windows. This will ensure you buy the right sized curtains. 
  2. Check to see if your windows have curtain rods. If yes, skip to step 4. 
  3. If not, you can install temporary adhesive wall hooks that can support a curtain rod. 
    • Use your windows measurements to find a curtain rod size that will cover your window area and purchase your curtain rod online or in store. 
    • Install your temporary wall hooks using the provided instructions. Ensure they can bear at least 5kgs of weight.
    • Make sure your curtain rod fits on your wall hooks and window dimensions, then you’re ready to install your curtains!
  4. Purchase blackout curtains suitable for your window dimensions. Make sure they are made of heavy, opaque fabric to block light and heat. 
  5. Once installed, keep your curtains closed before you go to sleep for the best results, and keep them closed during the hottest hours of the day (see tips). 


  • Block morning light: Closing your blackout curtains during the early morning, or before you go to sleep can prevent your home from heating up with the morning sun. 
  • Keep them dry: Make sure you check your windows for condensation and wipe them down. 
    • Blackout curtains are effective at blocking light, but like all curtains, they are susceptible to mould growth if condensation builds up on your windows. 

Buying Guide

  • Heavy fabric: thick materials like velvet are particularly effective at blocking light. Fabric is also a more eco-friendly and health-conscious alternative to PVC options.
  • Thermal Lining: Consider curtains with a thermal lining for added insulation 
  • Opacity: make sure curtains are labelled as “blackout”. Dark colours generally block light more effectively. 
  • Size: Curtains should be slightly wider and longer than the window to block light 
  • Detachable Linings: Some blackout curtains come with detachable linings, making them versatile for summer and winter. 
  • Customer reviews: always check reviews to find the best rated options for your needs.
