COLIBYOU (4 Pack) Corrugated Plastic Coroplast Sheets Sign 4mm Black 48" x 24"

After a number of trying I came upon these plastic sheets and they ended up being the final solution. Maybe there are more effective anti light/noise barrier out there on the market but I'm not up to the price most retailer and/or manufacturer ask, so I started scouting other (cheaper) probable solutions. After feeding a number of searching engines with I don't really know how many research criteria I ran into these plastic sheets just by chance, I made some research on them and eventually purchased them..."Et Voila"! ... After taking measures of both the plastic sheets and the windows panels I succeeded in having these sheet cut to measure, it was fairly easy although a little bit messy at the beginning. Finally I managed to cover all the windows in my studio unit and the light/noise level went down to a tenth to their previous level...Or so... To be sure, I'm still able to hear the fuss and the noise coming from the night Club right in the corner but it comes soo attenuated... Well...I definitely would recommend this items.

I took a chance and picked this up after there was some uncertainty about the way the flutes run on these sheets in the Q&A section. It just arrived and I figured I would let anyone else wondering know that I can confirm the fluting runs the long way (48") on these sheets. So if you use a coroplast cutter you can get 48" strips from it. Hope this helps someone!

I mean it good but hard to cut through

Used this as a cover for a plastic shelving unit outdoors. Zip tied it to the top to cover the open grid and it keeps things below dry.

I used to make R/C airplanes out of it now I'm making aquarium hoods.

Perfect for the project. Disappointed that shipping was more $ than the product but I understand. It should have come faster for the $ paid for shipping. Over all great product.

These 2'x4' boards were as expected. They were packed well, arrived in good condition and were completely opaque.I would buy again.

I used these for window covers for a SUV. Once I measure and cut them they fit and stay in place very well they totally blocked out light. I also use these to block off air vents in HVAC systems. They are pretty much plastic cardboard sheets. There are multiple uses for the stuff. Highly recommend.
