Dense Pack
Dense pack insulation is a high-performance solution that fills wall and floor cavities with tightly packed material to block airflow and improve thermal efficiency, without major construction. Whether you’re upgrading an older home or looking for blown-in wall insulation near me, this method delivers energy savings and sound control in one.

About This Service
Our dense pack insulation service uses high-pressure equipment to inject cellulose or fiberglass into wall, ceiling, or floor cavities. This method seals air leaks, improves R-value, and helps regulate indoor temperatures.
It’s especially effective in older homes that need retrofit insulation upgrades without opening up the walls, and adds the bonus of acoustic insulation.
Frequently Asked Questions
Does it reduce noise as well?
Yes, dense pack insulation provides excellent sound dampening, making it ideal for rooms near traffic, neighbors, or other noise sources.
How is it different from loose fill?
Unlike loose fill (used in open attics), dense pack is injected under pressure into enclosed cavities. It fills gaps tightly and is often part of air sealing strategies.
What is dense pack insulation?
Dense pack is a method of installing blown-in cellulose or fiberglass insulation under pressure to fill enclosed cavities. It blocks airflow, increases R-value, and offers a tight thermal barrier.
Where is it typically used?
It’s most effective in walls, floors, and ceilings, especially during retrofits where energy efficiency and air sealing are both needed.
Will it damage my drywall or siding?
No, we drill small access points that are professionally patched and blended after installation, leaving your walls intact and clean.
