Blown in insulation is a common type of insulation that can be installed in a home. It is made from several different types of materials, including rock wool, cellulose and fiberglass. Because this type of insulation is generally less expensive than other types, many building owners who are looking to better insulate their building without spending a fortune often choose this option. A Houston roofing contractor can always provide guidance when it comes to choosing the right type of insulation.
There are some major benefits to blown in insulation. Some insulation, such as cellulose and cotton, is made from recycled materials. This has less of an impact on the environment than other forms of insulation. Additionally, blown in insulation can be easily installed in both preexisting homes and new construction homes. It can also be used to insulate spaces that are already closed without disturbing the home's finish. When properly installed by a professional, the process is quick and not likely to cause problems for inhabitants who suffer from allergies.
No matter what type of blown in insulation is chosen, there are some general disadvantages. The major downside is that blown in insulation generally has a lower R value than rolled insulation. This is because it settles and often leaves gaps where heated or cooled air can escape.

The settling can also continue as the insulation ages. Essentially, the R value will continue to decrease throughout the lifespan of this type of insulation. There are some other downsides as well. For example, if homeowners plan to turn the attic into another living space, the blown in insulation can be extremely difficult to remove. Batt or rolled insulation can be easily picked up and discarded.
Finally, blown in insulation carries some potential health risks for home occupants. This insulation can be incredibly dusty when disturbed, and, if the area is not properly sealed, that dust can enter the building's ventilation system. The long term health effects of breathing these particles are not known and require more research. Due to this safety hazard, it is recommended that a professional be called in to install the insulation with the proper safety equipment.
While it seems like there may be more disadvantages than advantages when deciding on blown in insulation for a home's interior, this type of insulation is still a common choice for many building owners due to its ease of installation and low cost. An experienced roofer can provide further information for those who are considering blown in insulation.
