What is blown insulation?

Blown-in insulation, also known as loose-fill insulation, is a type of insulation material that is installed by blowing or spraying, and push insulation into wall cavities, attics, and other spaces in a building.

It is typically made of solid insulation material such as cellulose, vermiculite insulation, fiberglass, or mineral wool. Mostly used fiberglass batt insulation.

The process of installing blown-in, proper attic insulation involves using a special machine to blow or spray the insulation material into the desired area, as well as cellulose blown-in insulation.

The proper insulation is applied in a loose form, allowing it to fill the space and form a barrier against heat transfer. It can be used to insulate both new and existing buildings.

Attic floor insulation is known for its ability to effectively fill uneven and hard-to-reach spaces, providing better coverage and reducing air leakage compared to traditional batt insulation.

It can also be more cost-effective and efficient to install, as it can be easily applied to areas with obstructions such as pipes or wiring.

Overall, installing blown insulation, especially in attic flooring, is a popular choice for homeowners and builders looking to increase energy efficiency, reduce heating and cooling costs, and improve comfort levels in buildings.

Walk carefully and slowly

Step onto the plywood or sturdy board and walk slowly, being cautious to distribute your weight evenly. Take small steps and keep your balance in check. Avoid a blow in insulations.

Avoid stepping between the joists’

Stepping directly on the insulation between the joists may cause it to compress and lose its insulating effectiveness. Always walk on the joists or the temporary board you’ve laid down.

Use proper lighting

Ensure there is adequate lighting in the attic to see where you are stepping. If the attic is poorly lit, consider using a headlamp or work light to enhance visibility.

Blown insulation benefits

There are seven heat insulation performance factors:

  1. Blown-in insulation is highly effective in providing thermal insulation, reducing heat transfer, and keeping the home comfortable throughout the year. It helps to minimize the energy required to cool or heat the space, thereby reducing energy bills. The cloth-covered wiring is also a popular insulation.
  2. Blown-in insulation creates a barrier against air infiltration, preventing outside pollutants and allergens from entering the home. This can significantly improve indoor air quality, making it healthier for people. Also, use completely processed cellulose insulation on exterior wall too.
  3. Blown-in insulation carefully reduces the transmission of noise from outside sources or between rooms within the house. It creates a quieter and more peaceful living environment.
  4. Blown-in insulation can be easily installed in various areas of the home, including attic spaces, wall cavities, and hard-to-reach areas, as well as on ceiling joist. Its loose-fill nature allows it to be blown into tight spaces, ensuring complete coverage and effective insulation.
  5. Loose-fill fiberglass insulation is relatively affordable and cost-effective compared to other insulation options. It requires minimal labor and installation time, resulting in lower overall costs. Additionally, its excellent thermal performance can lead to energy savings and reduced utility bills in the long run.
  6. Blown-in insulation is typically made from recycled materials such as cellulose or fiberglass, making it an eco-friendly choice. It helps reduce waste and promotes sustainability by reusing materials that would otherwise end up in landfills.
  7. Blown fiberglass insulation materials are often treated with fire-retardant additives, making them resistant to flames and reducing the risk of a fire spreading. This can provide an added layer of safety and protection for the home and its occupants.

Overall, heat insulation performance is great and popular among private house owners.

Disadvantages of blown insulation

While blown-in home insulation can be an effective way to increase energy savings and reduce heating and cooling costs, there are some drawbacks to consider:

  1. Blown-in cellulose insulation may not provide complete coverage in all areas of the home, leading to spots with insufficient insulation and air leakage. Gaps or voids can occur if the installation process is not done properly or if obstacles such as wiring or plumbing are present.
  2. Blown-in cellulose insulation or insulation batting tends to settle over time due to gravity and air movement within the wall cavities. This can result in reduced insulation efficiency and the need for additional insulation in the future.
  3. If blown-in cellulose insulation is not properly installed or if moisture infiltrates the walls, it can lead to mold growth or dampness. Moisture-related problems can cause structural damage and health issues if not addressed promptly.
  4. Blown-in insulation is generally more difficult to install in existing homes compared to new construction. It can be challenging to access wall cavities, especially in older homes with narrow or obstructed spaces.
  5. Blown-in insulation typically requires specialized equipment and expertise to install correctly. While there are DIY options available, achieving optimal results may be challenging for homeowners without experience or training.
  6. Some blown-in insulation materials, such as fiberglass or cellulose, can create airborne particles that may irritate if inhaled. It is potentially dangerous materials. Proper precautions, such as wearing protective clothing and masks, should be taken during installation.
