Decisions, Decisions :: Thermal or Blackout?

Sometimes a standard lining just isn’t enough for your home. You might be looking for something to keep your home a little darker, or maybe you’d prefer something to keep your home even warmer, either way, a decision needs to be made.

To help you make the right decision and ensure that you are completely happy with your choice, we’ve compiled a list of the pros and cons of both thermal and blackout linings, allowing you to compare the two and choose the right one for your home.




  • Gives your home an added warmth – the thermal linings are designed to help keep the heat in your room, making them an excellent choice as the winter begins to set in and helping to create a snug, cosy atmosphere in your home
  • Energy efficient – because more warmth will be trapped in your room, you won’t need to keep popping the central heating on, helping you to cut the costs of your energy bills
  • Thicker lining to keep room shaded – while it won’t block out the light completely, it will stop as much flowing through the fabric, helping to keep your room slightly shaded and protected against any glare
  • Controls temperature inside effectively in both summer and winter – in the winter, the warmth from inside your home will be reflected back into your room whereas in the summer, the unwanted heat from outside will be reflected away to help you stay comfortable in your home all year round
  • Adds volume and body to fabric – with the added thickness of a thermal lining, your blinds and curtains will appear even more full and sumptuous than before



  • Lining is usually off-white, ecru colouring – the lining can sometimes cause lighter, more white blinds to appear less crisp as the light shines through, giving them a more natural, almost yellowy tint
  • Light still filters through – while this may not be a problem to many, if you are looking for something to keep the light away from your room, a thermal lining simply won’t be up to the task as it will still let soft light filter through
  • May still see silhouettes in the evening – although your room will be blocked from view, the lining may still allow silhouettes to be seen from outside if you have your lights on, so be careful if you’re dancing around your bedroom late at night!




  • Keeps the unwanted light at bay – if you’re fed up of that streetlight keeping you awake at night then a blackout lining is the one for you, it will keep all light blocked from your home, allowing you to get the best night’s sleep possible
  • Protects your privacy – the blackout lining is so thick, it will completely block both the view from inside and outside your room, making it an excellent companion to bedrooms and bathrooms
  • Thick lining adds volume to material – due to the thickness of the lining itself, your blinds and curtains will receive an additional boost of volume, giving them an even more full and more sumptuous finish
  • Neutral colour of lining means no interference with fabric colour – the lining itself is white in colour so it can be paired with neutral, natural and patterned blinds alike without leading to any discolouration
  • Less heat will escape through your windows – the heat in your home will struggle to push it’s way through the thicker lining, helping to keep it feeling a little warmer



  • Light is completely blocked out – if your home is naturally quite dark, you may want to steer away from a blackout lining as it will stop the remaining light from filtering in, meaning that you’ll be fully reliant on your lighting
  • Won’t control the temperature in your room as effectively – although it may become slightly warmer, it won’t be as energy efficient for you as a thermal lining
  • All your windows will look the same with blinds lowered – although this may not be an issue for everyone, from outside, all your blinds and curtains will appear white and plain

The lining you choose will fully depend on what functionality you want for your blind.

If you want it to keep the light out completely, then a blackout lining is the best option for you.

If you’re more interested in controlling the temperature in your home and saving money on your energy bills, then thermal is the way to go.

  1. . Interesting information. Thank you. My question is, can you have both interlining to add warmth plus blackout to block out light on a pair of small curtains, (not blinds) let’s say 1.20 wide and 1.40 drop?
    thank you.
