    Not for intended use 🏆
    Installing new pocket replacement windows. The company has preinstalled foam connected to the window on three sides. Bought this to custom fit and foam the bottom of the window.For a few dollars this made installation of the windows a breeze and the seal simple. Less messy.The spray foam tube doesn’t fit into all sides of the window so using caulk to finish off those spaces and happy that on the bottom there’s a wider thicker seal than even the preformed sides have. Those are half the size of this and the density of the sponge like material is less, as well.Whether for an AC or a window install this is a win on all counts.I’ve noticed the material has improved over the years. Compared to a few years ago this foam appears more long lasting. I’ve repurposed my first purchase over the years and it’s began to shed little specks. Appreciating the upgraded material use to produce this product⭐️⭐️⭐️⭐️⭐️/ updateI’m using this for a vintage 1900’s house when a window is opened and I need to seal the space between windows up top for portable ac install. Works very well. Great price. Delivery was seamless and timely.⭐️⭐️⭐️⭐️⭐️💯

    Works Like You’d Expect!
    Works just like the stuff from the hardware store down the road but delivered to your door. Used for my window unit AC and was easy to cut, not sticky, easy to remove, etc. Happy!

    Hydroponic Gro-Sponges People!
    I am quite tired of those crumbly, peat-based, fall-apart, organic gro-plugs/sponges that the hydro. Stores sell at ridiculous prices. And if come pre-moistened you don’t use them all right away, you might just find them a little moldy the next time you need to use them. That’s why I started searching for a viable alternative. Something that was cheap, that wouldn’t fall apart while using them and that could easily be customized to fit any Hydro, DWC or Aeroponic type of system that I can build.This is an open-celled foam that allows water and nutrients to be absorbed and allows roots to navigate through it and give support to the stems of seedlings and clones, holding the plants upright until they grow out into the surrounding media of your system or they can be used as the only media for supporting your plants.1.) For seed starting–Just take a sharp serrated knife and slit your already cut-to-size plug down from the top to the desired depth for the type of seeds you are starting.2.) For clones–Just take a sharp serrated knife and slit your already cut-to-size plug down the side a little past half way through the center of the plug. Then you can open the slit and gently place your clone into the plug without losing most of your rooting hormone.Side by side this foam looks just like the open-celled foam plugs that come with certain “Hydroponics gro-kits” that have I have purchased for ridiculous prices in the past.I hope this review will help others whom are searching for this same solution.

    Does it’s job
    I have one of those portable AC units and don’t want to nail the A/C vent plate around the window so I purchased the wider size weather strip to plug around the window and pushed down to seal. Works well.

    Great but not for between windows
    I didn’t really know what thickness I would need to fill a gap between the windows after putting a dryer vent in. These will only sit on top of the gap, not go between like I wanted, but that’s my fault since I didn’t know the size, but I’m still using them. They have adhesive on one side so I stuck it to the window for now over the gap. If you’re looking to fill a gap between two windows, then this probably isn’t the product you need. See picture. It’s great quality though. Might use what I have left on my front door that leaks air. I really think it would be good for that.

    Working to fill in gap between sash and frame of window
    used this to cut small pieces to fill gap betweem sash and frame of window. My builder grade windows seem to have a weak point allowing in air and moisture. This seems to be doing the trick.

  11. Saturated Sponge

    It’s foam, to be used with installing window air conditioners. There really isn’t much to it. It arrived as described..Got it to replace the one I used the years prior as there was an incident with my old AC, dirty water spilled over and saturated, so had to replace.Works just as well, except that the new one is nice and dry. Fills the gaps perfectly and helped with what turned out to be an effortless AC install.
