Weatherproofing, An Ongoing
Although I have already done a
lot of work, I haven't yet finished the upgrades to my
house's insulation and weatherproofing. The first thing I did
was insulate my hot water heater with an aluminum wrap, which
cost only about twenty-five dollars and stops about five
percent of the heat loss. Then, I began work on finding all
the air leaks around my windows. To do it effectively,
however, I had to wait for a really windy day; on such days I
could easily detect the slightest leak. After locating one, I
used my caulking gun to fill the cracks with silicone caulk.
As I worked, I was able to feel the room get warmer, so that
made it seem all worthwhile. Other things I have done include
adding insulation to the wall behind my basement sink and at
the top of the walls in my furnace room. That's some of what
I've done so far, but it's not over yet! Still to come
is adding new insulation strips to my patio doors and
replacing two old plate glass windows in my kitchen. I've
already seen the results on my Hydro bill, but there's one
problem. Actually, there are two problems: my teenage kids.
Nowadays, they've decided that you can never be too clean and
so have at least one, and often two, showers each day. Oh
well, at least my bill has stayed the same, even after the
recent hikes in the natural gas rates.
