Bvbasement
We are adding a 12x16 addition on our 45+ y/o house. The addition includes a basement area. My question is: Should we (or is it code) insulate the new basement floor and if so, with what? We live in Grand Rapids, MINNESOTA (not Michigan) where the average winter temp is COLD. The basement addition will be wood, not block or poured concrete. To the best of my knowledge the existing basement floor isn't insulated. Any assistance would be welcome, either thru this forum or email me at mpdavis55744@hotmail.com
Thanks for the help.

Hi mpdavis55744,

Are you asking about insulating the addition's floor, or the basement floor? I can understand that the addition's floor would be wood but is the basement floor a poured concrete floor??? And lastly, how much of the addition (and/or basement) is below grade?

OK, should have included that information. The entire addition's basement is below grade. It will be a poured concrete floor & foundation with frost footings. Does the floor in the new addition's basement area need some type of insulation between it and the soil under it?

Very good!

Make sure you have proper drainage when it comes to the gravel bed and, perhaps, drain tiling. Talk to the Pro about that. If your soil is 'damp', you may need a sump pump, center or corner drain, or whatever. A vapor barrier is a necessity too.

As far as insulation, you don't have to but if you want to, you can. Here is a decent look at what your slab may look like. In particular, pay attention to the cross-sectional diagram that's 2nd-from-the-bottom of the page, and the one above that. <a href="http://www.oldhouseweb.net/stories/Detailed/706.shtml">Slabs</a>

There are other ways to 'heat' a slab. You might want to look into a Radiant Heat System. It's a warm water based system that's 'snaked' , or weaved, over the slab or even built right into it, to warm the floor. IF your basement is used heavily, I'd consider this. If not, I'd consider passive insulation used in conjunction with electric heat or forced heat or a stove or whatever.

It's good you're looking into this before the job starts. Talk to a few contractors when you get your estimates about options. I suggest you get 10' high unfinished walls. This way, plumbing and electrical and duct work can be installed UNDER the joists AND your finished ceiling will still be 8' high. The additional cost is well worth it!

My best to ya and hope this helps. Oh, there are PLENTY of books out there that can help you with finished basement ideas. For the few $$$s they cost, it's a WHOLE lot cheaper to pay now than it is to pay later!
