Energy Efficiency 101: From the Ground Up
Warm Floors Start with an Insulated Basement
Yep, I told you so. It does get cold in the winter. And yes, I do now wear shoes and socks when I go outside to get our newspapers. No more bare feet until next summer.
In last month’s column, we talked about cold floors and what to do about them if your house is built on a slab. This month, we will focus our attention on houses that have crawl spaces or basements.
Here’s a real simple fact for starters. If your crawl space or basement is never cold, the floor above is never cold. The way to keep a basement warm in the winter is very simple. Just insulate the basement wall and add a little heat to the basement. In nearly every case, it costs very little to heat and cool an insulated basement.
For insulating basements I prefer to:
The basement is now well insulated and can easily be finished into living space in the future. Warmer basement equals warmer feet.
If your house has a crawl space, we prefer to treat it much like a basement.
Again, our intent is to keep the crawl space from ever being cold. The way to accomplish this is:
This will prevent cold exterior air from getting under the house. As a result, the crawl space will always be about the same temperature as the normal ground temperature.
In fact, the crawl space will probably be warmer as the heat from the house and heat from your ductwork (if the ductwork is located under your house), may warm that area several degrees.
The foundation wall can be insulated with sprayed cellulose, sprayed foam, or foam-board panels. This solution often makes a crawl space drier and can solve mold and mildew problems.
While many in our country agree with what I’ve just written, there are some who don’t. Some codes won’t allow this and there are even pest exterminators who won’t offer termite contracts if your crawl spaces are sealed. Therefore, you should be absolutely certain that your codes and pest exterminator will allow this as a solution.
Many thousands of homes now have “sealed” crawl spaces (with termite contracts), including my house. Those houses have lower utility bills and the occupants have warmer feet. In fact, I feel better already just thinking about it. See you next month.
