My basement has absolutely no heat and the basement door opens to the outsideThe part of the house up over it stays extremely coldThere is no insulation on the ceiling of the basement which is only the floor joists, etc for the house above itI am considering getting the fiberglass rolls to put inbetween the rafters since it seems to be the most afordable (I think)What thickness do I need to get for thisI don't understand the R-13, R-30, etc., or is there a cheaper, warmer route to go? Whatever I do, needs to be simple enough for ME to do it.
mom says its the weight of the fabric or thread count the higher the number the better the quality and cost
It is not cheap! but fibreglass is one of the least expensive! Thicker the better! If door opens to outside you have a walkout basement, insulate around doorjamb as well and windows if you have them? Measure to see if you have joist at 12 in on center or 16 in on center to get proper sizeYou need friction fit which means just that, slide it in and friction holds it in placeCut to fit more narrow voids 3/4 in larger than measurmentIf you have trouble in areas with insulation falling out because it`s not quite tight enough,you can zig zag sting across joist to hold it up! Then if you wish to drywall in future you can just board over string without any troubleI would install poly to contain fibreglass dust in basement.
