We just bought our first home. This house is a back drop split, built in 1955. The thing is that the crawl space ceiling is not insulated. The rooms above are the living, dinning and kitchen. The crawl space has vents to the outside. What I want to know is:
Firstly, Do we need to insulate the crawl space ceiling; how much a difference does it makeómeaning insulating it, and in what way.
Secondly, since itís a vented crawl space do we need to insulate the side walls also or not?
A little off the topic is that the laundry roomís outer wall is of concrete bricks that were just painted over. It is kind of an unfinished room. Rest of the walls in that room is finished. Beside the washer dryer unit, the boiler unit is also in that room. Question is do I need to insulate that outer wall also, how can it affect us if we donít do it this year. (We plan to eventually do it but our budget doesnít allow us to do it for now. How much not fixing these problems will affect our heating bill, is the question)
Please note that I live in NJ and in winter it gets really cold.
Any comments will be helpful!!!
