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! 
  • When it's hot, close the curtain to reduce heat coming in.
  • When it's cool out, open up the curtains to let hot air escape and avoid 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 shield 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. 
    • Ask your landlord for consent to make a minor modification
    • Using your window measurements, purchase a curtain rod to cover your window area, noting that the rod should extend past either side of the windows.
    • Install your temporary wall hooks using the provided instructions. Ensure they can bear at least 5 kgs 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.


  • 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.
