Frequently Asked Questions (FAQs)

1. Is thermal lining the same as blackout?

In short, blackout curtains are primarily designed to blackout a room by reducing the amount of light that can enter through the window. Thermal curtains, on the other hand, are primarily designed to reduce heat loss from a room's windows.

2. Do thermal curtain linings work?

Does thermal lining for curtains work? It certainly does! Thermal lining improves the R-value (the rating of insulation) while reducing the U-value (thermal transmittance).

3. Can you add thermal lining to curtains?

Adding a thermal lining to your existing curtains would go a long way in enhancing the functionality of your curtains. It would be a great use of your space time, as it will allow you to make big savings on your energy bills.

4. Do thermal curtains keep cold out?

While thermal curtains may not entirely keep cold out, they do raise the insulation level of windows, trapping cold air between the window and the curtain, preventing it from entering the room.
