Not sure if this the right category, but I'm remodeling my master bedroom and have insulation questions.
First some background. Older home, 1930 build, meaning-no insulation in the exterior walls. Bedrooms on second story with vinyl siding exterior and plaster/lath interior walls.
The masterbed room is cold in winter and drafty in some spots, so while I am repainting walls, fixing cracks I am considering blowing in insulation to increase the room's comfort. I am thinking of blowing from the inside. I am prepared to do some work on the walls, so the holes don't bother me. However, I don't want to replace all the plaster/lath with drywall.
My questions about blowing insulation revolve around moisture buildup. From what I can tell, there is no moisture barrier under the siding, and obviously by keeping the interior walls, I won't be able to put a moisture barrier under the interior surface.
If I were to blow in cellulose insulation, will that create condensation or moisture issues within the wall? And if so, is there a potential for mold in the cellulose insulation? Is there another insulation material that I should consider?
With my limited knowlege of this type of housing construction, I know that the airflow does a good job of keeping things dry within the walls, but not a good job of keeping the cold air out! And, I don't want to create more problems by adding insulation.
Sorry for the long post. Any advice greatly appreciated. I am considering kicking this part of the project off in a week or so. I may have a contractor handle the insulation, but since it is not a large room I am considering making it a DIY. Just want to be informed either way I go.
