What are the benefits of blown in insulation?
In the long run, adding insulation will lower your total energy bill. One way is to get blown insulation put into your home.
Blown in insulation is basically just an inflated version of the same old fiberglass insulation that has been around for decades. The difference with blown in is that it's pushed through a hose and then shot into crevices in walls and between joists in attics or ceilings.
The benefits of this type of retrofit include immediate noise reduction when you live close to freeways or airports; much faster installation than installing batt style natural fibers; less hazardous than open flame heating sources like gas hot water heaters; much safer form of insulating than using electrical wires if they are showing or framed without protective covering; blown insulation is blown into place, not stacked like batts (which can bow or sag); blown insulation can be installed over existing insulation to save money; blown in insulation provides more "custom" coverage than batts; blown in fiberglass removed from attics is less likely to be broken up by bats and other animals.
What are the disadvantages of blown in insulation?
Blown in insulation does cost between $0.60 and $1 per square foot depending on what type of blown in insulation you use, but it can run as high as $5 per square foot if using a foam insulating material. Also blown-in insulating materials will settle after installation due to settling or voids between joists or stud s. There are also lower R-value blown in insulation products that do not provide good energy savings or protection from moisture intrusion.
Is blown in insulation better than fiberglass?
Blown in is like fiberglass, but blown insulating materials are blown into place, not stacked like batts (which can bow or sag); blown insulation can be installed over existing insulation to save money; blown in insulation provides more "custom" coverage than batts; blown in fiberglass removed from attics is less likely to be broken up by bats and other animals.
These benefits make blown in insulating materials preferable to fiberglass for most homeowner applications. If you're doing your own project with blown-in cellulose, use only the

How does blown in insulation work?
The blown-in insulation is typically dispersed through a home or office by using some type of machine. It can be dispersed in a number of ways, such as open doorways and ducts, but it is most often done by shooting through metal coils that turns the air into an aerated spray.
The installation process starts with targeting the location and measuring out need for all insulation to be distributed evenly and customizing what type will suit the specified needs - if available - then start "shotgunning" walls with perfect timing so that no area goes without coverage. The wires draw themselves across ceiling joists which creates the best density than anything else on market today, keeping your pipes at constant temperatures where they're not prone to bursting from too much cold air.
The blown insulation can be any of the following:
Mineral wool (made from rock)
Fiberglass (glass fibers)
Cellulose (wood fiber)
Polystyrene foam (expanded polystyrene bead or XPS bead - blown in and sprayed in place or poured in place and expanded later with a blowing agent such as pentane, water blown polyurethane, hydrocarbon gasses blown polyurethane, HCFC blown foams.)
Hydrofluorocarbon blown foam. It's typically used to fill up note cavities that aren't already filled note complete rooms. All of the possible types of insulation that may fall into blown in insulation work equally as hard by providing the best air seal possible to protect your home from any related pests and an overall better energy rating.
Once blown into a room, blown in insulation does a great job of stopping air leakage - this means that a blown in insulation will satisfy all levels of insulation previously required without having to worry about dropping big bucks on top of it. Furthermore, blown in insulation can be installed more quickly than other types of insulating material, which is beneficial for those who want to get the job done as soon as possible. In some cases, blown-in insulation can reach R-values of up to R60 with just one application.
