Why thermally insulate a below-grade basement?
Please sheath your literary swords, put the pitch forks back in the barn, turn off those torches, I am well aware that every source I have reviewed recommends insulating a below grade basement, and doing it well. However, thinking out of the box, given my climate zone 7, where the below ground temp is like mid 50's all year round (my assumption), wouldn't it be welcome to have a basement in the low 60's while the outside temp is either 30 or conversely 85 degrees F? My current 1950's construction uninsulated basement feels great in the summer. I would think, if you can waterproof it, keeping the moisture out of the walls, so you don't have the efflorescence and constant dampness requiring running dehumidifier 365 days a year, like I have now, the temperature differential is a sort of primitive geo-thermal concept, no? So why bury all that foam/money?
