Fiberglass Blow-In
Loose-fill fiberglass insulation installed with specialized equipment for continuous coverage across interior attic spaces and appropriate exterior wall cavities.
What it is
Understanding Fiberglass Blow-In
Blown-in fiberglass insulation is made of loose fiberglass fibers that are installed using specialized equipment. It creates a continuous layer that can cover around framing, wiring, and other attic obstructions. Depending on the assembly, it can also be installed in enclosed wall cavities to improve coverage in finished or hard-to-access areas.
How It Works
The installer distributes the material across the designated space to achieve planned coverage and depth. The insulation layer slows heat transfer, while the final outcome is affected by installed depth, coverage, and the condition of the attic or wall assembly. Proper preparation keeps the material where it belongs and helps create even, consistent coverage.
Common applications
- Interior attic floors
- Interior ceiling cavities
- Exterior wall cavities
- Irregular attic spaces
- Areas around obstructions
- Existing homes
- Attic upgrades
- Hard-to-reach sections
Energy-efficiency considerations
Blown-in fiberglass can help reduce heat transfer through an attic floor. Proper installed depth, consistent coverage, air-sealing details, and the condition of the overall attic all influence performance.
Installation considerations
Professional installation helps ensure even distribution and appropriate coverage. Existing attic conditions, ventilation, access, air leakage, and the intended depth should be reviewed before work begins.
Important considerations
Plan Around the Full Building Assembly
Installed depth and even coverage are important to the finished insulation layer.
Attic air sealing should be considered alongside insulation to address air leakage paths.
The attic should be evaluated for access, ventilation, and existing conditions before installation.
