            It may help some. that's all we can say without knowing all about the location of the door and it's age and as far as recommending other products, we cannot help.

                  I needed some high density foam to fill the gap around my door frame. This product worked as expected. It significantly reduced the drafts that could be felt around the door frame. It was a cheap solution to making our house more energy efficient during the cold winter months. Easy to install.

                  Closing the gap.
                  Garage door had a gap. I could see the light coming in. I placed it on the threshold facing outward to fill the gap. I cant see the light from the garage anymore. Hopefully it helps with keeping my laundry room cooler here in Florida. My advice is if you see the light in a gap, the air is getting out. I hope it lasts. Either way an inexpensive easy fix.

                    The foam was easy to apply, and I used it between my sliding door and the fixed doggie door I also purchased some garage door seal and used it on the gap and now my house is cool or warm depending on the season.

                    Was great alternative for what i needed
                    i did not use this for weather stripping but used it to replace the foam strip on a paintball mask and it worked out great!!! I expected it to fall off after one use and was intended for a temporary fix but I've been using the mask every weekend for the past 2 months and it has been holding up great!

                      This was an excellent addition to the small quantity received with my new Freo AC. I’m so happy I initially purchased (2) because it’s slim enough to seal everything both inside and outside around the window air conditioner. I’m buying more just so I can always have these on hand!

                      Versatile and it holds up well.
                      I have used this foam weather strip in various sizes to help seal my attic access doors and the attic drop down ladder. It has worked well and has been installed for a couple of years. I have also used it for a couple of applications that are probably not recommend by the manufacturer. Such as to help seal the top of the door on my ageing electric smoker and to help seal the door on my chest type deep freezer; surprisingly enough it has held up well.
