Sustainable Home Insulation: Build Better, Live Better
Improve the air quality of homes and buildings with wood fiber insulation made from abundant, residual wood chips.
Build and Live in Healthier Spaces
TimberHP wood fiber insulation products are non-toxic, comfortable to handle and install, and provide fire resistance, industry-leading sound dampening, and moisture management for safe, quiet, vapor-open spaces.

Safe to Handle and Install
Our wood fiber batt, fill, and board insulation products are itch-free and contain no VOCs, formaldehyde, or added toxins. They are also Declare labeled and Red List Free.
- TimberBatt is designed for friction-fit installation, cuts cleanly, and doesn’t itch or produce debris.
- TimberFill is a safe-to-handle, debris-free dense pack blown in and attic blanket insulation. Where installers have to wear PPE to handle fiberglass and spray foam, TimberFill doesn’t require special protective gear and won’t irritate the skin or cause itchiness.
- TimberBoard installs with standard carpentry tools – no re-tooling required – and when you cut it, you get sawdust (no microplastics blowing away in the wind!)


Vapor-Open
Our wood fiber insulation solutions are vapor open and breathable. Air is able to move through the insulation, preventing moisture from becoming trapped and reducing the risk of condensation, mold, and rot.

“I wanted to commit Avesta to TimberHP because clean insulation was something we could do and a Maine-based company seemed like a no-brainer for us. Health and safety is important to our residents.”
Todd Rothstein, Director of Construction Services, Avesta Housing
