The house was built in the 80's. The insulation is in the attic. It's a grayish color. It's fluffy

Hi, All! If you were to insulate the outside walls of an old wooden house, what kind of insulation would you recommend using in the walls? My home is an old wooden two-story, American Four-Square that has aluminum siding on it. Thanks!

hopefully I'm in the right spot. I recently purchased an old house and gutted the entire thing. The house has completely new blown in insulation in the walls and new batt insulation in the attic and the crawl space. This house is so old that the floors in two of the rooms have no subfloor. Meaning,...

I want to insulate under my house, I have a crawl space with dirt on the floor and my floors are wood. What can I use to keep out the cold air from coming up through my wood floors during the winter months?

Have insulation in walls and attic that is contained in a package that easily punctures and when opened reveals a brown kind of sawdust? Anyone know what this is? I think it is useless for the walls as it settles making it useful for only the lower 1-3 feet of walls. House was built in the 60's.
