M-D Building Products 91890 84 in. White Premium Rubber Top and Sides Door Seal for Doors with Kerf/Channel

First, surely it is ONLY for those who have a groove around the door frame for this type of insulation.Also, consider that there is one stripe of the material for one side of a standard door. You will need to buy three of those for one standard door or five for two doors (one stripe should be enough for two short upper sides, at least for my doors).So, if the above is agreeable - this is what I have to say on the product:The material is just soft enough to be somewhat compressible, and part of the compressibility is in the "coiled" construction itself. So I expect it to last better than soft sponges do. The big deal for me is the possibility do adjust thickness of insulation by easily inserting a thin and cheap sponge stripes sold in any hardware store in rolls of various thickness and width. This is a big deal of advantage if the distance left for insulation between the door frame and the door is not the same all around. I cut from the sticky soft sponge stripes narrow stripes to fit the inner side of the insulating "coil" and inserted just in those places where I needed better contact. Easy, quick. Also, you may take that sponge out just unfolding and then re-folding the folds.Do not expect to double the thickness this way, but for some adjustments, when and if your situation requires it, this is a great product I was looking for. True, now is June and I just installed it - so the big test is far ahead. But, on the other hand, I see what it is and the actual result depends on construction you have, on the application of the right product for the situation AND then on the quality of the product. I just removed a very nice different type of insulation material, which was of good quality, but not reaching far enough, thus doing a very bad job. Just a couple of millimeters gap - and a draft in Winter is guaranteed... So, assess you situation and see if this is right for you.

Worked great. Made a huge difference during a very cold winter. My house is 30 years old and has some original weatherstripping. I replaced it around the front door and the walkout door and immediately noticed a difference in the lack of draft and the temperature in the inside areas near those doors.I would give it a 5 except that it is so thick and substantial that I was unable to mount it on the hinged side of either door. When I did that I was unable to close the doors (and they are both metal doors so no expansion problems due to temperature). So I had to leave the old stuff on that one side or replace it with something thinner.It was also very easy to work with. It fits easily into the slot in the frame and cuts easily with a pair of scissors.

We had to replace old 30+year door seal from our new pups who chewed it up. Found a perfect fit in this product. Easy to install is working great. Highly recommend.

Installation is simple, just rip out the old seal and push in the new one. Simple but takes time until you get a knack of it. Also, after installation the door needs to be pushed in a lot to squeeze the seal in order to open the lock.

My dog wrecked the old foam based weather strip and I bought a new foam based one at Home Depot; however, the Home Depot weather strip would fall out whenever you opened the door. I found this all-rubber one at Home Depot but they only had it in black and I wanted the white so I ordered from here. The strip was really easy to fit, just slides into the jamb, you cut the excess off and it's all done. It's been in a few weeks now and hasn't fallen out and there is no light coming through the jamb so it looks like it's working.Note: this is not adhesive, it fits in a groove built into your door jamb.

I needed something wide enough to cover and close the gap at the bottom of my back door. For some reason the bottom half has a wider gap between the frame and door than the top and the other weather stripping was just too narrow. This closed that gap, however, since it is thicker you have to push the door pretty hard to get it to stay closed. I walked away after closing and came back to see the door had popped open by itself. It will take a little getting used to having to push harder to make sure the door is closed securely but I would rather do that than have a gap at the bottom that allows light (sun), heat and bugs easy access to my home.

This weather-stripping worked great for me! I needed to weather-proof the exterior door to my deck but the cheap adhesive-backed stripping from the big-box hardware was useless. We have several dogs who go in and out the door and, when they do, their bodies just peel the stripping off. My door has a kerf; so I thought I'd try it. It's a lot more expensive than the cheap weather-stripping but it's worth it! I had to order three packages of it because one package is enough to do only one side of the door. The first strip went in one side like a breeze and the top strip did too. The last strip was a bit more of a problem until I discovered I was trying to fit in backwards. I flipped it over and it went in smoothly, just like the first two. The dogs continue to go in and out the door but this weather-stripping stays in, anchored by the part that goes into the kerf. I'm going to order more to install on my garage door; so I highly recommend it!

A nice upgrade to the vinyl-covered foam insulation. This one seems much more durable and should last longer than the original builder-grade stuff did. Installs easily in the kerf space, the fins hold it in very securely. These come ONE strip per package. It takes 3 packages per door; or 5 per two doors-- IF they are average width and height. We have a wider 9' high door and need to buy an extra package to cover the additional run. I do wish this came in longer lengths so we don't have any gaps on the long edges.
