    4Works Great For Sealing Vinyl-Window Channel Gaps
    By HighExpectations
    Purchased this M-D brand of cord weatherstripping last year and used it to seal the pesky channel gaps on all my double-pane, single-hung windows.

    APPLICATION: After a few minutes of working with this stuff, I discovered that it helps to spend a moment or two kneading a small amount into a ball first. Doing so transfers the warmth of your hands to the clay-like weatherstripping material, making it much more pliable/workable, and therefore much easier to smush into oddly shaped nooks and crannies, such as those at the top corners of your single- or double-hung window sashes, where they meet the channels on either side (these are notorious energy-sucking gaps).

    It took me about five to ten minutes per window to install this in the aforementioned channel gaps, and along the top of every sash, including the tricky spaces around the window locks.

    THE RESULTS: This stuff performed better than expected last year through a rather cold Midwestern winter.

    Window drafts that had always been noticeable were all but eliminated, as was the condensation that used to form just above the window locks despite a moderate interior humidity level of about 40 percent.

    THE DOWNSIDES: There are two aspects of this product that I don't like.

    First, it's not pretty. No matter how much you work with it, it's still going to look like you crammed gray Play-Doh along the tops of your windows. It's light gray and my windows are white vinyl, so you really only notice it if you're looking at the window frame. Still, if I were to suggest an improvement, it'd be to figure a way to lighten the color to white.

    The second bummer turned out to be the springtime removal of the weatherstripping cord material from my windows. Of course, I had to remove this stuff before I could open any of the windows to which I applied it. Sadly, that turned out to be a bit more time consuming than the application process. Come springtime, I discovered that months of winter cold had hardened the clay-like material considerably. I used a plastic butter knife to pry it loose, but found flecks of it remained stuck to the vinyl window frames here and there. I ended up having to scrub it away with a mild solution of water and white vinegar, which doesn't sound like a big deal until you have to do it on 18 windows.

    LESSON LEARNED: This year I plan to use this same M-D brand weatherstripping cord again in the channel gaps on my windows, but not along the tops. Instead, I'm going to experiment with some interior transparent weather-sealing tape along the tops of the sashes and around the window locks. My hope is that the weather-sealing tape will be just as effective as the clay-like weatherstripping cord, but easier to remove come spring. We'll find out in five months, I guess … To be continued …

    The shelf life of M/D Rope Caulk never seems to dry out, as so many other brands do.

    4similar to Mortite, for less
    By Andrea Matthews
    My family has used Mortite for years - some years back the product changed to thinner, softer strips. Being softer makes it more flexible (but it sticks more to one's fingers, making it a little harder to apply), and being thinner makes it less easy to re-use, as it breaks into shorter strips. So I was a little more sensitized to the cost, which has been going up, of course. This product is very much the same, and the Amazon price is definitely less. So as a product, 4-stars, and in comparison to Mortite, 5-stars for price.
