DONGPAI Thermal Insulated Door Curtain, Winter Thicken Cotton Windproof Soundproof Temporary Door Single Insulation Door Cover for Winter to Keep Warm

This is my second time purchasing this product. The first time the door covering looked like I had sewn it (it puckered.) I was still so thrilled to have something covering my door, I didn't care. My door is old and I would replace it, but a good front door is expensive! Anyway, the cover reduced the amount of wind and cold and heat coming in. I can really tell the difference. I don't think it does much to dampen the sound. I primed it like it was a canvas and I'm painting a mural on it. This purchase, I bought two, and both of them were expertly sewn. I'm hanging these on the stairwell to see it they can't help reduce my heating costs.
