Blown-in insulation, also known as loose-fill insulation, is a type of insulation that is installed by blowing it into attics, walls, and other cavities using a special hose. It is made from tiny particles of Fiberglass, Cellulose, or Rockwool.

Blown-in insulation is a good choice for insulating hard-to-reach areas, such as attics with irregular shapes or walls with existing electrical wiring or plumbing. It can also help to seal air leaks, which can improve energy efficiency and comfort.

Here are some of the benefits of blown-in insulation:

Increased Energy Efficiency: Blown insulation forms a consistent layer that fills in all nooks and crannies, reducing air leaks and improving your home's overall thermal performance. This translates to lower energy bills as your HVAC system won't have to work as hard to maintain comfortable temperatures.

Better Conformity:Unlike batt insulation which can leave gaps around obstructions, blown insulation easily conforms to uneven surfaces and around pipes and wires, creating a more uniform insulating layer.

Reduced Noise Transfer: The dense, filling nature of blown insulation helps dampen sound transmission, making your home quieter and more peaceful.

Improved Indoor Air Quality: Some blown-in insulation materials, like cellulose, can help trap dust and allergens, contributing to better indoor air quality.

Fire Resistance: Certain blown-in insulation materials are treated with fire retardants, adding an extra layer of safety to your home.

Environmental Friendliness: Cellulose, a common type of blown-in insulation, is made from recycled paper products, making it an eco-friendly choice.

Blown insulation, while a great option for many homes, does have some drawbacks to consider:

Moisture susceptibility: Both cellulose and fiberglass, common blown-in materials, can absorb moisture. This can be a problem in humid climates or if there are leaks. Wet insulation loses its insulating ability and can lead to mold growth.

Settling: Blown insulation, particularly cellulose, can settle over time, reducing its effectiveness in those areas. This may require topping up the insulation in the future.

Installation complexity: Installing blown-in insulation requires a professional to ensure proper application and avoid issues like blocking vents or overloading ceilings.

Weight: Cellulose insulation, especially, can be heavy. In older homes with weak ceilings, blown-in cellulose might not be the best option.
