Sustainable Performance
Pure wood fiber insulation has been perfected and used in Europe for more than 20 years, but this powerful and proven technology has never been available in North America – until now. Our wood fiber batt, fill, and board insulating products are healthy for people and the planet, and deliver superior acoustic comfort and thermal management – naturally.
That is sustainable performance.
Insulation You Can Feel Good About
There is a shift in building design and construction in the U.S as architects, builders, and homeowners seek out products that reduce carbon footprints, improve occupant health, and deliver better performance over the life of the building. Our wood fiber insulation solutions check every box—plus, our products are sustainably sourced and manufactured right here in the U.S.
Build better without compromise.
Vapor-Open
Wind-tight and water-resistant performance that repels moisture without trapping humidity, reducing the potential for mold, rot, or condensation.
Unmatched Acoustics
With industry-leading sound dampening, it’s perfect for walls, floors, and ceilings in residential, multifamily, or commercial applications.
Superior Thermal Barrier
High R-values per inch deliver thermal storage, draft reduction, and temperature stabilization for an excellent thermal barrier and comfort year-round.
Fire Resistant
All TimberHP wood fiber insulation solutions are tested to ASTM E84 ratings for fire and smoke spread, and use no chemical fire retardants.
Wood Fiber Insulation FAQs
Q: Are TimberHP’s insulating products fire resistant?
A: Yes! TimberBatt and TimberFill achieve an ASTM E84 Class A flame and smoke spread rating, while TimberBoard achieves Class B without any added fire retardants. TimberBatt and TimberFill are treated with liquified borate, which saturates the wood fiber and provides a superior long-term solution for fire, bug, and moisture/mold resistance. Independent certification through ICC-ES further validates fire-resistance claims and safe installation guidelines.
Q: Are TimberHP wood fiber insulation products compliant with building codes and standards?
A: Of course! Our wood fiber insulation products are designed to meet International Building Code (IBC) and International Residential Code (IRC) standards, making TimberBatt, TimberFill, and TimberBoard a great fit for residential, multi-family, and commercial construction.
Q: What are the R-values of TimberHP wood fiber insulation products?
A: TimberBatt delivers R-3.7 to R-4 per inch, and TimberBoard ranges between R-3.4 to R-3.7 per inch, with excellent thermal mass for year-round comfort. TimberFill delivers about R-3.8 per inch.
Q: How does wood fiber insulation make a building or home “healthier”?
A: Wood fiber insulation is vapor-open and effectively manages moisture and condensation, helping prevent mold and rot, and promoting improved air quality in the built environment.
Q: How is TimberHP wood fiber insulation different from mineral wool or other sustainable insulation materials?
A: TimberHP is sustainable at the source; it’s made using abundant residual softwood chips that are produced during normal lumberyard activities. Wood fiber is a naturally renewable resource, and is naturally carbon storing, meaning it reduces the overall carbon footprint of the built environment. TimberHP products are also sourced and manufactured in America, and are safe and comfortable to handle and install.
Q: What kind of sound dampening does wood fiber insulation provide?
A: Wood fiber insulation delivers exceptional acoustic performance. Fire-rated assemblies incorporating TimberHP deliver Sound Transmission Class (STC) ratings of 50–55, and Outdoor-Indoor Transmission Class (OITC) ratings predominantly above 30. TimberBatt alone boasts an exceptional Noise Reduction Coefficient (NRC) of 1.15, far exceeding the desired minimum of 0.80.
At Basciani and Sons we are always striving to stay ahead of the curve when it comes to building science, quality and value. In our most recent custom home we used TimberHP’s TimberFill to dense-pack our exterior walls.
Timberfill is made in the USA , has a class A fire and smoke spread rating, and is manufactured with recycled wood scrapes from sustainably managed forests. Healthy for our customers, staff and the environment. It’s a “win win”.
