Spray foam insulation:
- Application: Applied as a liquid, which expands and hardens into a foam upon contact.
- Coverage: Adheres to surfaces, sealing gaps and cracks effectively.
- R-Value: Provides high R-value per inch, offering excellent thermal insulation.
- Air Barrier: Acts as an air barrier, preventing air infiltration and heat loss.
- Moisture Barrier: Resistant to moisture, reducing the risk of mold and mildew.
- Installation: Requires professional installation due to the specialized equipment and techniques involved.
- Cost: Typically more expensive upfront but offers long-term energy savings.
loose fill insulation:
- Application: Installed using a blowing machine, which distributes loose fibers or particles evenly.
- Coverage: Can be blown into attics, walls, and other cavities, filling irregular spaces effectively.
- R-Value: R-value depends on the material used (such as fiberglass or cellulose) and thickness.
- Air Barrier: May require additional air sealing to prevent air leakage.
- Moisture Barrier: Some materials offer moisture resistance, but additional measures may be needed in high-moisture areas.
- Installation: Can be DIY-friendly for small areas but may require professional installation for larger projects.
- Cost: Generally more affordable upfront compared to spray foam insulation.
Both types of insulation have their advantages and are suitable for different applications and budgets. It’s essential to consider factors such as your property’s specific needs, insulation goals, and budget constraints when choosing between spray foam and blown-in insulation. Consulting with a professional insulation contractor can help determine the best option for your project.
