Q:

As it starts to get cold outside, the foyer and kitchen floor (tiled floor and even other areas of the floor with hardwood) of my house is really cold. I can have the heat running at 70 degrees but the floor itself stays cold. Is it worthwhile to insulate the ceiling joists of my basement? Would this help? My basement is mostly above ground (I have full windows in basement) so I suspect the basement gets colder than a normal bsement. Or should I look into chaulking/spray foaming the area where the house sits on the cinder blocks, there's already insulation in those areas, not sure how well it's sealed though. Thank you for your help.

Sorry, I didn't see post earlier, was busy, but yes, R-30 is good for ceilings not to close to recessed lighting if you have any, about 6"-8" apart if you do.

Thanks for the great answers. So I purchased a few packs of faced R30 a few weeks ago. Would that not be good to use on the ceilings?
Thank you

Yes, you should insulate the ceiling joist of the basement, either an R-30 batt, or an open packet or high density foam if your budget can afford it. If you are insulating the floor joist of your house and the joist is sitting on a stem wall, batt insulation is not recommended because it is exposed to the ground or the elements. I am a huge proponent of polyurethane foam, with the price continue to come down, it will be the standard in a few years, replacing batt. It gives your home an airtight, waterproof seal, like a bubble against the elements.http://www.dimensionbuildlv.com
