Thermal Door Curtain or Weatherstripping: What Stops a Draught
They solve different problems. One seals a shut door, the other covers an open one.
Where the cold comes from
From gaps, mostly. Air moves through the cracks around doors and windows all winter, and the heating pays for it. ENERGY STAR describes the fix like this:
A well-sealed envelope, coupled with the right amount of insulation, can make a real difference on your utility bills.
Sealing is the first job for any door that stays shut. Weatherstripping costs little and stays in place all year.
What does a thermal curtain add?
A curtain works when the door is open, or when it opens twenty times a day. A FEGO Thermal Insulated Door Curtain hangs inside the frame and closes on 50 magnets after each pass, so the warm air stays in while people and pets go through.
It is padded: Oxford fabric on both faces with a thick cotton filling. It is a curtain, not a wall, and it does not replace the door at night.

A back door to the yard, a porch door, a door between the house and a cold garage, a French door that leaks. For a garage workshop, the Winter Garage Door Curtain does the same job across an opening up to 18 x 8 ft.

Which one should you choose?
Both, if the door is draughty and busy. Seal the gaps first. Then hang a Thermal Insulated Door Curtain, which closes on 50 magnets, on the door that people use all day, and take it down in spring.
