CRL Clear Jalousie and Louver Slat Vinyl - 100 ft

this is the best! I moved into an old house with big gaps between all the slats and it was getting super cold at night cause I'm basically living with open windows. NOT ANYMORE! this fit my slats perfectly and closed up all the gaps. looking forward to the lower cost of heating and cooling. sound reduction is also a bonus.

Bought a roll of this material a couple of years ago and found it to work great. It was slightly stiffer material which allowed the "fin" to really extend out and seal out the water between the slats. Decided to go all in and just bought three more rolls. This newer batch seemed to be of a slightly softer material which I really liked at first because it was easier to handle. However, as I got in about 80 - 90 feet in the roll, it appeared that when they spooled the material, it was too tight. The material had gotten twisted, so the tension made it harder to install. Also, certain areas of the "fin" was either wavy, which affected the seal, or was smashed down nearly flat, which again negatively affected the seal. I'm hopeful that while its installed and straight, keeping the windows shut tight in the sunlight a couple of days will help to alleviate this issue. Overall, I would purchase the product again, but I would potentially factor in a 10-15% wastage for that last length of material on the inner part of the spool. I believe if the spooling was just a bit looser, it would improve the delivered product.

We installed these on some windows in an old building to stop the drafts. They worked great at stopping the draft and keeping the house warm during winter months. Our maintenance guy said that it was easy to install.

Believe the other reviews! I certainly should have before I purchased this. While in theory it would have been an excellent product to help seal the gaps between jalousie windows, in practice it’s not - mainly because, as the other negative reviews have stated, the material is all warped. The closer you get to the center of the spool, the worse it gets. I’d say about halfway through the spool the rubber is so warped that it’s impossible to put on your windows. The only way I got mine to stay was to use some type of adhesive and clips on each jalousie to keep them somewhat straight until the glue dried. It was a massive pain to use these.I would have returned this, but I’d already cut up the material.I think unless someone can find a way to have the spool unravel evenly and keep the rubber straight, this item is mostly useless.

Been looking for a solution that will close the gap between 6mm glass louvres. Appearance did not obstruct the clear view of the window. Easy to install and remove. Thick enough to look like it will last. The part that will connect to the upper slat would have been perfect if it were longer. The only challenge I encountered was when I was less than a quarter to the end of the roll. The strips were twisted making it difficult to measure and cut accurately. The lip that will connect to the upper slat was nearly folded so the seal was not tight and we’re with gaps. Overall, still value for money - helped with insulation and sound proofing.

There was a small portion of the order that was able to be applied to the window and stay put. The majority of the roll was kinked and rolled in such a way that it was unable to flatten out enough to be useable. I think the concept is nice, but it didn't work for us.

I did placed it on my windows, but due to the fact that it's all bended in a roll, it doesn't cover what is suppose to cover on the windows.

This is a great product to help keep your jalousie windows to close tighter. It sometimes gets very windy where I live so this helps keep the house cleaner during dust storms. The box came with no instructions for installation so it took me a while to figure out which side to slip over the glass but once I did they were fairly easy to install but a little bit frustrating for someone like me who has little patience. I have short width windows so had to cut them catefully. Word of caution: be sure to cut them carefully to the correct size. If they are too long they will fall off.
