Blow-In Insulation
Many older homes were originally insulated with batt insulation. While this worked well at the time, batt insulation tends to lose its R-value (insulating power) as it ages. A quick and cost-effective way to improve comfort and efficiency is to apply blow-in insulation over the existing insulation.
Blow-in insulation is great for filling small gaps and hard-to-reach areas, while also helping to dampen sound—keeping outside noise out and inside noise in.
Benefits of Blow-In Insulation
- Cost-Effective Upgrade – An affordable way to reinsulate without removing old materials.
- Fills Gaps – Expands into small cracks and voids where batt insulation falls short.
- Sound Dampening – Helps reduce noise transfer between rooms and from outdoors.
Things to Consider
While blow-in insulation offers clear benefits, it does have some limitations compared to spray foam:
- Obstructions – Wall studs, outlet boxes, and drain pipes can prevent full coverage, leaving behind voids.
- Settling Over Time – Blow-in insulation can compress or settle by a few inches, which reduces its R-value.
- Not as Long-Lasting – Spray foam insulation provides a stronger seal and longer lifespan.
✅ Blow-in insulation is an effective solution for boosting energy efficiency on a budget, but for homeowners looking for maximum performance and durability, our spray foam insulation options may be the better choice.
