Blown in insulation

Is it worth having blown in insulation in the walls? Does it get
everywhere? Under the windows?
I've seen new construction on TV where they put up plastic mesh over the
studs and fill the walls with blown in insulation. Is this the same
stuff they use in old homes?

there is a fiberglass that is blown in with a latex spray on it that
stays suspended , the paper blown in stuff settles alot. getting it
inside the complete cavity depends on the experience of the installer.

Actually, if they use the wet spray, they don't even have to put up the net.
check out www.centralfiber.com . They wet spray it on, then shave it off
flush with the studs. In existing walls, they drill holes and blow it in
there dry. If it's done properly, there's no settling to worry about.

If you're referring to blown in insulation in an existing house, then a
plastic mesh is not required. Usually, new constructions and remodeling will
have the "expanding foam" type insulation installed between the studs, then
they shave off any excess.

Existing homes can have the blown in insulation. The most common type is
"cellulose". Cellulose insulation is composed of up to 85 percent recycled
newsprint. The remaining content is commonly a mixture of borate and
ammonium sulfate that functions as a fire retardant. These chemicals also
deter rodents, insects, and mold. The other two blown in insulation types
are foam and fiberglass.

If having insulation blown in, it's usually done from the exterior of the
house. They will drill a hole every 16 inches between the studs. This will
fill in every stud column and do under the windows, also. If the home has
siding, they will remove the siding to drill the holes, then plug the holes
and reinstall the siding to cover it. You'll never know it was done. For
brick homes, they drill through the bricks and plug with mortar. If a room
with exterior walls is being remodeled and in need of insulation, it's best
to have it blown in from the inside since the walls can be repaired easier.

Blown in insulation can also be used over/with existing fiberglass
insulation such as in the attic. It reaches areas which rolled insulation
cannot, therefore, being advantageous for proper insulation.

closed cell foam is now poured in walls, higher r value than cellouse.

if you have knob and tube wiring dont insulate it may cause a fire
hazard......

the wiring designed for open air could overheat and cause a fire
