Blown-in Insulation

What is Blown-In Insulation?‍

Blown-in insulation, as the name suggests, is a method where insulating materials are blown or sprayed into wall cavities, attics, or floors to insulate spaces effectively. Typically, it's made up of loose-fill particles of fiberglass or cellulose, which are produced using recycled materials like newsprint.

Key Statistics and Benefits of Blown-In Insulation

1. Energy Efficiency: Blown-in insulation can increase a home's energy efficiency significantly. Homes without proper insulation lose about 20-30% of their conditioned air through leaks, gaps, or inadequate insulation.
2. Cost Savings: According to the U.S. Department of Energy, homeowners can save up to 15% on heating and cooling costs (or an average of 11% on total energy costs) by air sealing their homes and adding insulation in attics, floors over crawl spaces, and accessible basement rim joists.
3. Environmental Impact: Blown-in cellulose insulation is typically made from 80-85% recycled paper, which means it's not only energy-efficient but also environmentally-friendly.
4. Soundproofing: Besides thermal benefits, blown-in insulation also provides excellent acoustic benefits, dampening sound and reducing noise transfer between rooms and from external sources.
5. Filling Gaps: Due to its loose-fill nature, blown-in insulation is perfect for tight spaces, irregularly shaped areas, and around obstructions where other insulation types might be less effective.

Installation Process

‍Blown-in insulation requires specialized equipment. A professional installer will use a machine to blow the insulation into the desired areas, ensuring an even spread and the right density to prevent settling over time.

Lifespan and Maintenance

‍When properly installed, blown-in insulation can last for decades. It's resistant to moisture, which prevents mold growth. However, it's always a good idea to have periodic checks to ensure no settling or moisture problems, especially after significant roof leaks or renovations.

Final Thought

‍Whether you're retrofitting an existing space or considering insulation options for a new project, blown-in insulation offers a flexible, efficient, and eco-friendly solution. With the potential for significant energy savings and a more comfortable living environment, it's an investment that pays off in both the short and long term.
