Insulation in your home is important to reduce heat loss and gain and save energy. How well a particular type of insulation works is determined by its R-value, which is a measure of the insulation’s resistance to the transfer of heat.
Install rolls or batts of faced insulation in an uninsulated attic, with the paper facing down toward the ceiling. For an attic that already has insulation, install unfaced rolls or batts of insulation on top of the existing insulation. Another option is to blow loose fiberglass or cellulose insulation on top of the existing insulation.

In the video, you said if you want to add more insulation to existing attics, they use this roll out material. It more of a insulation that looks like its in a plastic pick bag rolling out. What is that? THanks
I have a home located in the Mojave Desert in California. My home is approximately 1600 sq. ft. If I am going to insulate my attic, won’t the sq. footage be about the same as the house?
I have an old fashioned tile roof house. The tiles are nailed to strips of wood. There is no solid ceiling. The insulation I have is extremely dirty and has been wet. Can I remove it and clean the attic, seal the leaks before I put in new insulation?
maybe you can answer a question for me please, I live in n.j. zone 4 the building inspector wants me to put in a r-49 in the attic of a addition , r-49 is not available here so my question is can I put up a faced r-39 and then in the attic lay a unfaced r-13 the opposite way, will that then give me a r factor of 52 which is more then he wants, your help would be appricated
How much insulation between rooms & laundry to prevent from hearing?
Sometimes, it’s not so much about ‘how much’ than it is ‘what type?’
We recommend Rockwool’s soundproof insulation.
Thanks for your question!
Nice overview of attic insulation. I would recommend links to articles/vids about attic airflow (ballasts) and dealing with electrical wires & junction boxes, light housings (which should not be covered with insulation. As always, check your local community and state codes and ask questions when uncertain.
