Conclusion | Tips to choosing the best fabric for curtain lining 

Functionality – If you seek total privacy and a total room darkening option, 100% blockout curtain linings are your go to option. 

Fabric for lining curtains: Your design consultant should assist you with this, but as a general rule, choosing more dense or thicker fabric will be much more effective at keeping cold air out and is an overall better energy saving option. 

Blackout effectiveness: Another areas your design consultant should help you with. Make sure that your curtain linings are labeled as “blackout” or “100% blockout”. This will ensure they effectively block the suns light from outside. 

Décor – If you have the option, opt for linings that matches your décor as best as you can. The main purpose of linings are for functionality at the end of the day. 

Price: Depending on your budget, opting for 100% blockouts and the 70% blockout (options 1 and 2 ) can be more expensive although in the long run, they can benefit by helping you save on your energy bills. Polycotton (option 3) lining are the most affordable but may not be as effective as keeping the cold air out.
