Builder has given us choice of either fiberglass or cellulose insulation
for walls in new house construction. Which is better? He told us the
cellulose has a slightly higher R factor and makes the walls air tight.
Does the cellulose settle more than the fiberglass? Is cellulose more
prone to having mold or insect problems?

any help would be appreciated

This is Turtle.

I would never put Cellulose in my house again. Before i put it on top of the
fiber glass this cellulose stuff my house was very dust free and had to dust
very little. I install it and everything in the house get's dusty every 3 to 4
days and my 90% media filter plugs up every week with the gray fiber dust which
looks just like the cellulose stuff. And yes i have made the attic area air
tight to the living area but very little help. It has been a nitemare but now
it has been about 6 or 7 years and it's slow down a good bit now. If given a
choice of Cellulose or nothing. I would take nothing. Hindsight is always better
than forsight.

which is better for you will depend on many factors

if one has a higher r value, you can always add more of the other to
equalize

some of the differences mentioned in some of my previous posts he

Cellulose:
settles and also causes *visible* dust in your house 24/7 when not entirely
sealed from the interior of your house (tough to do, hvac ducting
breaks down over time and breathes, then cellulose gets in it
and ultimately into your house);
cellulose is usually recycled newspaper with fire retardent added;
cellulose can be about a 30% radiant barrier;
cellulose seals against (stops) wind blowing through your house/walls
if cellulose gets wet it is destroyed
cellulose is not carcinogenic (doesn't cause cancer)


Fiberglass:
can cause *invisible* "dust" in a house (see links below - also, look inside
a fiberglass insulated attic at night with a flashlight, while wearing an
appropriate breathing mask - you will see millions of tiny particles
floating around in the air = fiberglass);
fiberglass is glass fibers;
fiberglass doesn't seal against the wind blowing through your house/walls;
fiberglass is not a radiant barrier;
fiberglass can be dried and reused if it gets wet;
fiberglass can be carcinogenic (can cause cancer)

potential carcinogen" http://www.nqinc.com/faq2.html
[carcinogen meaning it can cause cancer - some people in advanced stages of
cancer remove all fiberglass ffrom their homes and go back in with
cellulose, which is not a carcinogen]

according to dr. hulda clark (cancer expert, who has already been slammed on
this discussion group and by the medical industry in general) at:

http://www.drhuldaclark.org/therapy_cleanup_home.asp

"Fiberglass insulation has microscopically small bits of glass that are free
to blow into the air. When house drafts pull it into the air you will inhale
them. They cut their way through your lungs and organs like millions of tiny
knives, spreading through your body, since there is no way out for them. You
smell nothing and feel nothing. This makes it a very sinister poison. Your
body, though, recognizes these sharp, pointed bits and tries to stop their
spread by sequestering them in cysts.

Most solid malignant [i.e. cancerous] tumors contain fiberglass or asbestos,
another glass-like particle. In nearly all cases a hole can be found in the
ceiling or walls, leading to fiberglass insulated parts of the house. When
these holes are sealed in an air-tight manner the house air no longer is
positive for fiberglass. Covering with paneling is not sufficient. Check
your dwelling for uncovered fiberglass. Repair immediately. Search for small
screw holes intended for pictures, or electric outlet plates that are
missing.

Also remove fiberglass jackets from water heater and fiberglass filter from
furnace. Replace with foain or carbon. Best of all, hire a crew to remove it
all from your home, and replace insulation with blown-in shredded paper
[cellulose] or other innocuous substance.

Never build a new house using fiberglass for any purpose."

dr. clark also recommends against the use of galvanized pipe (pvc is
recommended) or copper pipe (or lead solder used to join copper pipe,
prevalant up until 1988 or so) in homes, as they can be poisonous to humans

After reading your post it appears fiberglass insulation is truly
something to bw corncerned about.

Get a second opinion here, Effi appears to be one of the fringe folks.
The web site she/he cited:

http://www.nqinc.com/faq2.html

is hosted by folks that use scare tactics to market there products.


From this site you can get an MSDS

http://www.guardianfiberglass.com/pr.../eng_msds1.htm

It reads:

SECTION V: HEALTH HAZARDS/PERSONAL PROTECTIVE EQUIPMENT
Primary Route of Entry: Inhalation. Fiberglass wool may cause mechanical
irritation of the upper respiratory tract. Use of a respirator such as 3M
model 9900 or equivalent is recommended. Operations which generate high
airborne fiber concentrations (over 10 fibers per cc) require additional
respiratory protection.
Skin Contact: Direct contact with the skin may cause mechanical irritation.
If irritation occurs, long sleeves, loose fitting clothing, gloves, and eye
protection are recommended. Wash exposed areas with soap and water after
handling. Wash clothes separately and rinse out washer after each use.

Following a thorough review of all the medical data available, the
International Agency for Research on Cancer (IARC) has classified glass wool
insulation as Group #3, "not classifiable as to carcinogenicity to humans".
IARC has stated there is "no evidence of increased risks of lung cancer or
of mesothelloma...from occupational exposures during the manufacture of
these materials, and inadequate evidence overall of any cancer risk."


------------------------------end
quote-----------------------------------------

While you are free to believe anything you want, I suspect that in this day
in age when toasters come with warnings not to use them in the bath tub the
companies lawyers would not sign off on the wording in the MSDS unless it
was the best known medical facts.

which is better for you will depend on many factors

What abt using SIP panels vs either cellulose or
fiberglass?

Just bypass the two all together?

Only seen them on tv, and they seemed like they were whole wall units,
not somehting you can put in later into an existing home.

All true, cellulose is treated to resist insects and mold as well as fire.
Cellulose is much less expensive 70sqft R12 3.2" is $11 vs $25 for 88sqft
fiberglass R12

Foam is best with the highest R value, Icynene is R 3.5" polyurethane
R6-7per". Cellulose is good if it is wet blown with a glue binder. Dry
it is a dust problem. Fiberglass is good but the lowest R value. Google,
there is alot to different insulations. It depends on what contractors
in your area offer.

Fiberglass takes a long time to settle compared to cellulose. Cellulose
can get into area that fiberglass can't. Just make sure you have proper
venting. There should not be a dust problem as long as the cellulose is
not disturbed and there are no ducts in the attic. One issue is an
attic fan or bathroom exhaust fans. They can disturb the insulation and
create dust. One way I solved this was to take a large duct tube and
put it over the exhaust fan in the attic (this also solves the problem
of keeping the insulation 3 inches from the fixture). You can cap the
tube to prevent additional energy loss and run the exhaust hose through
the cap or side.

The cellulose will settle eventually and I think you should go up
there in 5 years and add a couple inches. As far as the entrance to the
attic goes, I would section it off and lay down batting so when you go
up there, a ton of cellulose doesn't fall out and get everywhere. Just
make sure you have proper venting between the rafters before you spray
that stuff in!
