This house has blown insulation in the attic and has been
making the ceiling sag for quite a few years and now the
ceiling needs to be replaced in several rooms.
Can I just throw that insulation away or do I need to do
anything special with it?
Is it normal for this type of insulation to make a ceiling sag?
Some say 1/2" drywall on 24" centre ceiling joists/trusses
will sag on it's own. The inspector where I'm building said
1/2" is ok by code but recommends 5/8" on my 24" centre ceilings
You haven't given us much to go on. If it's not a moisture
problem like others have suggested and you are going to redrywall
then you may want to find out if I'm right.
