a buddy ran 2 by 4s the other direction, added blown in insulation and

no home has enough storage space, at resale time attic storage is a

As far as FG dust, insulation made in the last hundred years has a

Where do these 2X8's come from? Most houses built in the last 50 years or
so use pre-engineered trusses and I don't recall seeing any (many?) that use
anything more than 2X4's.

I also have not seen this F/G insulation with the plastic sheet attached
that you talk about. Most F/G batts that I have seen and used come packed
in a big plastic bag but when you cut the bag open all you get are loose
batts, no foil, no paper, no plastic. Also what about rock wool insulation,
blown in F/G or blown in cellulose?

Storing stuff in an undeveloped attic is just a bad idea.

I also, have never seen plastic on FG insulation. I have seen paper
backing, but it would be down towards the ceiling. OH, and BTW, the 7.25"
of insulation you'd have with your 2x8's is only about half of what you
need.

Perhaps in this case a fan could be beneficial. But so could a white roof.
But you don't see many light colored roof anymore. Some people just create

I agree, the (newer) garage has a light tan/off-white seamed steel
roof, the attic fan in the garage was nonfunctional up until about a
month ago (I finally got around to replacing the thermoswitch.) Even
so it was always much cooler than the house which has a dark brown
aluminum fake-shingle roof. I wish they'd used the stuff that they
used on the garage on the house as well. I don't know how much
difference the color makes and how much is due to the garage being
shorter/more shaded, but it is significant.

Anthony: the fan does not necessarily have to be in the roof, although
many fans and vents are.
In our case we installed fan in the in the end gable of single storey
house.
It draws out hot air. Fresh air comes in via the soffit vents and a
vent in the gable at the other end of the house. During the winter in
this fairly severe climate we close off and/or remove the fan. Right
now it's on a switch but intend to put it on a thermostat so it cuts
in when the attic area gets hot!

You must not live in the south. Natural ventilation simply won't do
the job in some cases -- I have plenty, and my attic still reaches
150 degrees without a fan (which holds it to 120 +/-).

Hi,
I just had a whole house fan installed and what a difference it has
made. We have only used our ac 1 time and we get 90-100+ degees all
summer. It cools the attic and keeps the house cool. It can cost to
have it installed, but ours came with a life time warranty and we got
a $100 rebate from our electric company. The cost was about $900 to
install. We purchased it from the 'Home and Garden Show' in our
neighbor town. Good luck, Trax

An attic exhaust fan can help. Before we installed ours, we could
feel the heat coming off the upstairs ceiling, even though we have
reasonably good insulation (of course one can always use more, so
that's an alternative to reach the same goal). Now the ceiling is
cool. The downside is that the electricity to run the fan isn't
free. However, I think (haven't figured out how to prove, though)
that the decreased load on the A/C pays to power the fan, and the
A/C should last longer now that it isn't working as hard.

Remember, though, that typically only something like 20% of your heat
gain (as I recall) is through the ceiling.

It's all a big balancing act.

The facts are that heat enters the home via radiation, convection and
conduction.
Its better and cheaper to use passive measures rather than electricity-
which costs more every day.
A white or light colored roof reflects the heat away from the inside
of the home.
Polyurethane insulation is better by far than fiber glass , its also
best when sprayed in as it takes up the shape of the space and fills
all the holes.
Polystyrene fitted under the ceiling stops the the remaining heat
conducted by the wood frame.
