Product clearly stated 12 in width multiple times. In reality the product is actually 11 5/8 inch wide, that's a significant difference. Don't recommend this supplier.

We used this to help keep our milking parlor warmer. It was easy to cut strips to length needed, and we also were able to attach them to a removable aluminum bar. This will allow us to take them down in the summer months when we need the parlor to be cooler. These worked great in the recent negative temperatures.

I used this product to build a air conditions stall for my horse that has COPD in the summer ( Florida)I took her only 4 days to understand it was ok to through the curtain. now she walk in there when she is feeling over heated.

These are heavy duty. I attached with screws and washers. These do block sound, but only a few decibels. Easily cut with scissors. I was disappointed that my roll was bowed, which caused each strip to hang in a curved manner. Otherwise they seem high quality and durable.
