Sustainable NW Wood is the Northwest Distributor for TimberHP products. Wood fiber insulation is a replacement for petroleum based, toxic and extractive insulation products. TimberHP's wood fiber insulation products can help meet ambitious energy, health and sustainability goals for residential, multifamily and commercial building projects. Safe to handle, easy to install, with fire resistance, unmatched acoustics, creating an excellent thermal barrier for year round comfort.


PLACE
Sourced from TimberHP,  the first company in the U.S.  to manufacture wood fiber insulation, located in Madison, Maine at the former home of the Madison Paper Mill.   In a region of the country where the economy was tied to the declining paper industry, TimberHP is breathing new life into rural manufacturing and helping to create a market for small diameter pulp trees and residual wood chips from milling activities to make their wood fiber insulation products. 

PURPOSE
TimberBOARD is a rigid exterior continuous insulation for wall, floor, and roof applications.  TimberBATT is  flexible, high-density wood fiber batt insulation engineered for superior thermal, acoustic, and moisture performance in modern assemblies. 
The "HP" stands for high performance, a healthy planet, and healthy people.  No VOCs, formaldehyde or added toxins.  Red List Free.  Performance beyond the R-value, these products are industry-leading for noise reduction for acoustical insulation solutions,  provide fire resistance and moisture management for safe, quiet, vapor-open spaces.

PEOPLE
The benefits of wood fiber insulation go beyond sustainability, and promote healthier indoor air quality in homes and buildings so occupants can live and breathe easier.  Safe to handle and install, vapor open and breathable, and reduces the risk of condensation, mold and rot.  The innovation of this product results in a carbon negative, non toxic insulation alternative, while utilizing undervalued logs and wood chips from the collapsing paper pulp industry,  providing jobs to displaced workers.
