yet another insulation question
Just moved in.
I have a small basement with an attached raised crawlspace. The crawlspace is accessed via a 54"x54" opening on the left of basement and my garage is on the right. (basement area in middle, house on a slight hill with garage under right side of home.) The basement has the washer, dryer, furnace and hot water heater in it and all ductwork in this area is unisulated. The garage is insulated on the basement side, ceiling and back wall that is also adjacent to basement.
My question: The crawlspace which is under the livingroom and kitchen has no insulation between the floor joists, would be benificial to insulate?
The ductwork in the crawl isn't insulated, but I assume it radiates off some heat thus warming the area between these two rooms. Additionally, the crawl has one vent to the outside. The livingroom has a hardwood floor and the kitchen has vinyl. So far we haven't noticed the two rooms being particularly cold, but it has just dropped to low 30's (NJ).
while I am posting this, attic has R13 insulation, no soffit or ridge vents, does have a gable vent at each end and an attic fan. Should I put more insulation down, add a ridge vent or other suggestions? House is around 2000sq ft. What are the savings?
Do you close the vent for the crawlspace in the winter?
Just moved in two months ago, so not yet, but I will close it.
