Here's the problem. These insulations are all rated R-13. Three of them
cost less initially than the forth. But the cheaper ones are made with
glass fibers, Or ground up newspaper with borax in them for a fire retardant,
neither are particularly good insulators and are useless at stopping air
infiltration. Which means that wind and cold air and pollen and dust and
humidity will leak around them and go through them...right into your house.
These days, with home energy costs up so dramatically, the
smart choice is no longer the cheapest insulation you can buy... but the
best insulation you can buy. Which also just happens to be the only one
that can stop your heated or cooled air from leaking away so easily...
With energy cost on the rise, choosing the best insulation for a new
home is more important than ever. But how in the world can we expect someone
to pay for an upgrade like foam when it can cost twice times as much as
fiberglass?
Let’s look at it a bit closer. Is Foam really more expensive
to use than Fiberglass or Cellulose?
Insulating your home or building with Fiberglass or Cellulose may be
cheaper than Foam up front, but are you really getting the same comfort
with the Foam that you would with the other’s? Not at all! With
Fiberglass you will get a product that does not really measure at the
correct R-Value that you paid for. It also can become airborne every time
you pressurize and depressurize your home. As far as an air barrier forget
it. This is the same product that you have put in your furnace for years
to filter the air. They can’t have it both ways. Cellulose is a
much better insulator then Fiberglass, but do you really want the dust
in your house? They have to put bleach on cellulose to make it fire retardant.
If you think you’re breathing this, your right.
So back to the money part. If you have to pay $12500 more for the foam
then this should add about $83.00 per month. Now let’s figure that
your energy bill is going to run $400.00 per month. If we can save you
40% on your bill then you just saved $160.00 Your net savings will be
$77.00 per month. Every month for the life of your home. Now here is where
it gets interesting. Let’s say you take that $77.00 and put it in
your retirement for the life of the mortgage. The 30 year average for
the Stock market is an 11% gain per year. This will grow to $141601.45.
If you think that these numbers are going to grow in the future then
you’re probably right. Energy is not going to get any cheaper.
So which one was more expensive?
Fiberglass or the Foam
