Hello;
My front step is poured concrete on top of a cold room that is poured as an extension of the foundation.
It has a small door opening from the basement, and is about 2m2.
It is insulated 'out' from the main basement.
The cold room never worked well because:
-it had no vents and tended to get damp
-about 1/3 of the wall area, plus the room ceiling/step pad are above ground, leading to excess warmth in the summer and excess cold in the winter.
I just had the above-ground portion re-built (removed the old step, repoured the concrete, with a bond to the below-ground walls.
I got them to incorporate 2 x 4" vent ducts (4" PVC pipe) near the top of the wall, so I can now attach a thermo-siphon type venting arrangement.
I am wondering about insulating the inside of the above-ground concrete.
Would rigid foam insulation, attached directly to the concrete with adhesive ('liquid nail'?), be a good way to go?
I am thinking that insulting the above-ground concrete will buffer the winter and summer temperatures, so the room temperature is set more by the ground temperature.
Am I likely to get mold between the insulation and the concrete?
cheers, Doug
