Bought this to separate a small room off our kitchen that contains the washer/dryer, furnace and hot water heater. This thing makes a world of difference, especially with the sound. I didn't think it would do that much being plastic and only bought it for some temperature barrier from the back door in the utility room but when this is closed you can barely hear anything running in the room compared to when there was no door. Amazing! And it has helped with the temperature as well, keeping the kitchen warmer when it is closed. Worth the purchase.
