Garage Door Insulation Kits (?)

[tsorfas]

Came across one of those garage door insulation kits on Home Depot. Does anyone use them? Do they really make a differences? Some reviews report 10-15 difference after installing them but I’m find that hard to believe. They can be found for about $70 so the cost isn’t crazy but if it’s not going to do anything...
Wanted to see if anyone has tried them here

I've literally had tabs open for this for a while meaning to get back to look into it further

I'll share what I have open

I still haven't committed to doing it, but will likely do so soon. I think applying them mid June is ideal

Is it worth insulating my garage door if my garage has no heat source? : HomeImprovement

I'm sure it will help slightly. Considering heat/cold leaks in perpetuity from an area leaking insulation it's a good idea to put one in regardless to a garage thats connected to a house.

I'd only look into it if your garage doors have zero/minimal insulation already. When I got new garage doors I was told spending lots of money for nominally higher R-values in the highest trim wasn't worth it. I would look at air leaks; make sure your door is pressed up against the seals and the bottom seal is good.

If you mean 10-15* warmer just from adding insulation to a garage door...i'd be very skeptical.
