We had our carpets removed a while ago and installed laminate flooring instead.As a result, the house is not as warm as it used to be.Will it help if I add R13 insulation in the basement ceiling ? Will it keep the living room floor (which is just above the basement) warmer ?On the same manner, will adding another layer of insulation to the attic help in the winter and summer as well ?As for the mositure barrier paper, if I understand correctly, it should be facing up both cases, right ?
A vapor barrier always will go the heated side. But in you situation, just use unfaced insualtion in both applications. DO NOT use any plastic to cover anything. This will only trap moisture.
Paper faces the conditioned space. Adding insulation always helps.
I post some insulation in my storage that's below my mattress room and that i do experience the version - I grew up in Philly and we live in a row residing house and our basement replaced into some what under floor so all we had to do replaced into insulate the residing house windows - yet once you have partitions that are dealing with the wind you are able to ought to post some thing there additionally - warmth will upward thrust some in case you are able to insulate your attic that's going to help - in case you have severe ceilings you additionally can decide to think of a pair of ceiling fan
Every home and layout is different so it's difficult to give the right answer. Adding insulation to the basement ceiling would help out and would not hurt anything but why is it so much colder in the basement? Yes basements always appear to be cooler but you might want to look into that. Typically in basements very cheap single pane windows are installed, box sills around the primeter should also have insulation in them. For your attic; at a quick glance if you can see the ceiling joists on the floor of the attic you need more insulation. Common fiberglass batts you would find are R-9 up to possibly R-19 for a single layer, you should have at least and R-28, if not add additional. In northern regions new construction they are putting in R-42. If you have a loose fill insulation the rule of the thumb is R-3 per inch of product, just a guideline if manufacture spec's are not available. Vapor barrier always goes towards the warm side; in the attic the barrier would go down or closest to the drywall on the ceiling below. Basement probably isn't has picky but technically would go up against the underside of the floor.
