I am worried about my first brew blowing out. I thought I would get something to protect my floors. My wife, being the pragmatist, pointed out a piece of aluminum about 2 and a half by about 4 and a half feet long to put in the closet floor. I keep my house around 72 degrees F and I know that fermentation raises temp of your wort. My wort is maintaining a temp of 72 and I feel that the big piece of aluminum is facilitating this stability. Since I am a Newb, is this good or should I move the aluminum out from my closet?
