Garage door thermal curtain?

[Olivera]

Does anyone use a thermal/workshop curtain for inside a garage door in an attempt to keep more heat in? Seems to be a thing in the US but not very common here?

Just google "garage door curtain insulation". If you have a roller garage door it's a bit less convenient, but ours is a once piece up and over and I've glued black foam between the metal bracing - basically triangles of insulation.

I've also glued a garage door rubber strip along the bottom and a standard household weather strip to reduce the gap above the garage door - we don't park cars in the garage so no exhaust fume issues
