Duct Mask, register sealing film 8x200 |
| 10/16/2012 |
| We had an energy audit performed on our 80+ yr old home. The staff used this duct mask film around all our window air conditioners. It is so easy to use, kept the hot air out and was so easy to remove. Now that winter is on its way I use it around some our drafty windows. It is an amazing product! |
