Hi Itchy,
I have determined that my
attic is under-insulated. Our town allows for a a free energy
inspection of your home, they pay the inspector, to give advice as
to how to make your home more efficient.
The inspector told me I need
more insulation in my attic. Not surprised, this house has always
been cold. But, he did say I have to be very careful as the
existing insulation, which is clearly not enough, is some stuff
called vermaculite. I guess this stuff has asbestos in it. I have a
respirator, Osha approved for working around asbestos, and except
for anticipating having to shove some insulation in the corners and
around attic baffles so I don't block soffit vents, and probably on
my stomach on plywood, it should be a matter of rolling the
insulation out. Before I get around this stuff, I wanted to ask
someone that would know, their opinion about working around this
vermaculite stuff.
Thanks in advance for your
opinion.

I have ran into vermiculite
insulation many times during my insulating career. It is a flaky
mineral that looks similar to mica.... read

A SPECIAL NOTE ON CONSUMER ENERGY TAX
CREDITS:
OK guys. I know last year I was
slacking and didn't get the tax credits listed on this website
until March and I heard about it from some of you. No need to gripe
to me this year because I have it posted earlier. But you might
want to bitch about the lack of credits available. In fact it
appears to be even worse!
Our fearless leaders in Washington
didn't do much of anything regarding insulation and weatherization
tax credits. In fact, according to U.S. Department of Energy
reports last years credits haven't been extended into
2012.
Here is what I know of so far. If I
learn any more I'll post it and if you find out of any additional
information please let me know:
If you bought any of the below items
before 12/31/11 you can take the credits for tax year 2011...

Hello,
We are in the process of
insulating a cathedral ceiling in our remodeled house. We had to
pony up to all the existing rafters with 2 x 8's as they were too
small (house was built in the 60's with rough sawn fir... good
tough stuff, but 2 x 4's don't allow much airflow, with
proper R value insulation!) We put in the "rafter buddies" in
every space from the very peak to the soffits. (We just had the
roof redone so there are many vents, and we just redid the soffits
with the alum kind instead of the vents in solid material that
was there before!)
My question: how do you
insulate at the very peak? Insulation is square, the peak is not...
do you just stuff more in that triangular gap? Like I said, we have
put the foam rafter vents in the entire length from the big peak
beam to soffit. I just don't know how much to stuff in that space.
Fill it up with scrap? If so, does it matter what direction
the scrap goes in? I would think the gap needs to be filled, but
want to make sure its done properly before my other half puts the
vapor barrier up!!
Thanks!!

Normally with vaulted
or cathedral ceilings you would start insulating from the top and
work your way down. The batt of insulation is butted against the
ridge beam (peak). Because of the angle you will have a small
triangular area that could use more insulation where the batt meets
the beam... read

I am insulating my garage and
need to know if I need to apply a vapor barrier between the
concrete walls and the wool batting. The walls are poured concrete
and have been framed out. I received a supply of wool batting but
although the manufacturer says it resists the moisture, I live on
Orcas Island in Washington and moisture is out life out here. I
will also be putting it in the ceiling. So I wanted to be sure
about the layering before getting started. I am doing it myself to
cut costs so I would appreciate any free advice you pass along to
me. Thank you so much.

Vapor barriers - to add on or not.
Everyone has an opinion on this one and that includes me. My
experience tells me that unless you live in a desert climate you
need a vapor barrier. Many builders don't add vapor barriers to
garage walls as they are not considered a living space. The purpose
of the vapor barrier on concrete garage walls is to prevent warm
air from condensing on the cooler garage concrete walls. If that
happens moisture can run down the garage concrete walls and you may
experience dry rot, mildew or mold...read

Hey Itchy
My old home has knob and tube
wiring in the attic floor. There is no insulation over it and I'm
am losing a lot of heat. What's the best way to insulate over knob
and tube wiring?
Marcus B.

Adding insulation over knob and tube
wiring can be dangerous and you have several issues to consider.
While I've insulated over knob and tube wiring a in the past (only
because the owner insisted) I wouldn't recommend it. They actually
had plywood boxes built to completely cover the old but but live
wiring and we were able to insulate over it. You would never want
to directly cover it with insulation though and I'll tell you
why... read
