Blackout or Thermal Curtain Lining? Which Should You Choose?
If you’re investing in made-to-measure curtains, you’ll probably spend plenty of time choosing the perfect fabric, colour and heading style.
However, one decision that often confuses is selecting the right curtain lining.
One of the most common questions homeowners ask is:
Should I choose blackout or thermal curtain lining?
Although these two lining options are often grouped, they are designed to achieve different things.
Understanding how each lining works will help you choose made-to-measure curtains that not only look beautiful but also perform exactly as you expect.
What’s The Difference Between Blackout And Thermal Curtain Lining?
At first glance, blackout and thermal linings may appear very similar, but they have different priorities.
Blackout lining is primarily designed to reduce the amount of light entering a room.
Thermal lining is designed to improve insulation by helping reduce heat loss during the winter and reducing solar heat gain during the summer.
Some curtain linings offer elements of both, but understanding your main priority will help you make the right decision.
When Should You Choose Blackout Curtain Lining?
Blackout lining is ideal when controlling light is your main objective.
It can help create a darker room by significantly reducing the amount of daylight entering through your windows, making it particularly popular for:
- Bedrooms
- Children’s bedrooms
- Nurseries
- Guest bedrooms
- Homes where shift workers need to sleep during the day
Blackout lining also provides an excellent level of privacy during the evening when lights are on inside your home.
It’s important to remember that blackout lining is designed to reduce light entering through the curtain fabric.
As with most curtain systems, small amounts of light may still enter around the edges of the curtains.
When Should You Choose Thermal Curtain Lining?
Thermal lining is designed with comfort and energy efficiency in mind.
By adding an extra insulating layer behind the curtain fabric, thermal lining can help reduce heat escaping through your windows during colder months while also helping reduce heat entering the room during warmer weather.
Thermal lining is often an excellent choice for:
- Living rooms
- Older properties
- Bay windows
- Large glazed areas
- Rooms that feel cold during winter
- South-facing rooms that become warm during summer
While thermal lining won’t replace your home’s insulation, it can help improve comfort throughout the year.
Which Is Better For Bedrooms?
Bedrooms are often where homeowners find it hardest to choose.
If your priority is creating a darker sleeping environment, blackout lining is usually the better option.
However, if your bedroom feels cold during winter, thermal lining may also be worth considering.
The right choice depends on what’s more important to you:
- Reducing early morning daylight
- Improving warmth and comfort
- Or finding the best balance between the two
Which Is Better For Living Rooms?
For many living rooms, thermal lining is often the more practical choice.
Living rooms are typically spaces where homeowners want to enjoy natural daylight while making the room feel warm and comfortable throughout the year.
If glare from the sun isn’t a major issue, thermal lining can help improve comfort without significantly changing the overall appearance of your made-to-measure curtains.
However, every home is different. Large south-facing windows may benefit from additional light control, while older homes may prioritise insulation.
Can You Have The Best Of Both?
Many homeowners assume they have to choose one or the other, but that’s not always the case.
Depending on the curtain system and fabric you choose, it’s sometimes possible to achieve both improved light control and improved insulation.
The most suitable option will depend on the room, your chosen fabric and how you use the space.
This is one reason why discussing your requirements before ordering made-to-measure curtains is so valuable.
A professional can help you choose the lining that best matches your priorities rather than simply selecting the most expensive option.
Which Curtain Lining Should You Choose?
The answer comes down to one simple question:
What do you want your curtains to achieve?
If your priority is:
✔ Sleeping in a darker room – Blackout lining is usually the better choice.
✔ Improving warmth and comfort – Thermal lining may be more suitable.
✔ Reducing glare while enjoying natural daylight – Your choice will depend on how the room is used and the orientation of your windows.
Every room in your home has different requirements, which is why there isn’t a single lining that’s right for everyone.
Conclusion
So, should you choose blackout or thermal curtain lining?
The answer depends on what matters most to you.
If reducing light is your main priority, blackout lining is often the ideal solution.
If you’re looking to improve comfort and help reduce heat loss during the colder months, thermal lining may be the better choice.
Both lining options offer valuable benefits, and neither is inherently better than the other.
The right decision comes from understanding how you use the room and what you want your made-to-measure curtains to achieve.
Choosing the correct lining will ensure your curtains don’t just enhance the appearance of your room—they’ll also deliver the comfort, privacy and performance you’re looking for.
