Damp-spray cellulose: a lost art in the age of spray foam. 🏡
While spray foam gets most of the attention these days, one of the most underrated insulation methods has been quietly doing its job for decades.
And its benefits are hard to ignore.
🔇 Outstanding sound dampening for a quieter, more comfortable home.
🌡️ Thermal performance comparable to open-cell spray foam, with an R-value around R-3.7 per inch.
🌱 Made primarily from recycled materials, offering a more sustainable alternative to petroleum-based foam insulation.
🏠 A tighter, more energy-efficient home. Damp-spray cellulose fills gaps and conforms around wiring, plumbing, and framing. Its dense coverage helps resist airflow through wall cavities better than traditional fiberglass batts, though it doesn’t replace the air sealing provided by spray foam.
💧 No on-site polyurethane foam reaction, while still delivering excellent thermal and acoustic performance.
It’s not new. It’s not flashy. And it takes skill to install correctly.
Different homes call for different solutions. Knowing which one to use is what separates insulation installers from insulation professionals.
