Answer:
Hi Marc, it sounds as if you want to keep the floor warm over a foundation, I would recommend not insulating the floor and insulating the walls of the foundation, or basement belowThe reason is that cold moist air will rise into that floor insulation and create mouldIf you insulate the foundation walls with about R-20 you will find none of the outside cold air will come through and your floor will be room temperatureAlso, if you have a sand base in that foundation, place vapour barrier (6mil) over the floor to keep cool ground moisture from passing throughCompanies can spray foam poly urethane insulation which is a bit pricey but exceptionally well sealed for about $2.50 per square footor you can apply dow blue foam with caulking to the foundationOutside walls, not the floor is the way to go!
Floor joists were on 12 centers for many years, also insulation is to slow heat exchange and heat rises so walls and ceilings are insulated floors are more rareHow you install the type of insulation you want is your choiceThe facing on the insulation is a vapor barrier to stop warm/moist air from reaching the insulation and getting wet thus loosing insulating properties You have a non standard situation and most items you want are a low volume turnover so they will either be special order or an online item Maybe a cut of the insulation will work, not the support wires since they are for a 24 space but are actually about 26 since they have a Z shape to install themA cold floor is no fun but you need to do more research about the type of insulation and the fire hazards involved.
I think this is what I would doI am from a much colder climate than MassIf in doubt, go for the maximum R you canI would buy the 24 unfaced batts and cut them lengthwiseThen I would, if your space underneath allows it (headroom or whatever or is it just a crawl space underneath?), apply 1 1/2 inch foil faced foam insulation boards on to the underside of the joistsThis stuff adds quite a bit of R value for 1 1/2 inches thicknessThis is what is also done in older homes that do not have 2x6 studs on the exterior walls but only 2x4'sIt makes up quite a bit for R value instead of basically rebuilding or replacing all the outside walls The 2x8's on 12 centers make up for 2x10's on 16 inch centersIt might be meeting codes in Mass but it is easy to checkIt is existing so you won't be changing it anywayDoes it seem solid to you or does it move a lot with regular use, walking across it, etc?
well the scientifical term for work is force times distanceand also the distance will have to be in meters (M) and the force will have to be in newtons (N)so in other works you are to convert 48 inches to meters and 18000 pounds to newtonsi am not doing it cuase i dont fell like working my mind off.
