The product behind the performance
We don't install
just any cellulose.
Valley Wide specifies Mountain Fiber—a family-owned American manufacturer focused on cellulose insulation for nearly 50 years.
Its loose-fill attic product settles into irregular cavities and wraps around framing, pipes, and wiring to create the complete coverage a high-performance home deserves.

Luxury you can hear.
Dense cellulose fibers help absorb sound for bedrooms, offices, and living spaces that feel calmer.
Recycled in the U.S.A.
A proven cellulose material made with recycled paper rather than virgin fiberglass.
Made to resist.
Mountain Fiber describes its insulation as fire and insect resistant for added confidence.
High-performance by design
The difference
is in the details.
Insulation isn't just about an R-value. It's about how completely it fills your attic, how it handles sound, and what it leaves behind.
Mountain Fiber blown-in cellulose creates a dense, seamless thermal blanket from recycled paper, installed with close attention to depth and coverage.
WHOLE-HOME COMFORT, CONSIDERED
A premium result
starts with coverage.
Balanced across thermal performance, air-gap coverage, sound control, recycled content, and installation value.
