Safe, Reliable, Sustainable Insulation. That’s Our Promise.
Sustainability is more than one thing – it’s about responsible sourcing, low-impact manufacturing, high-performance materials, and supporting a circular economy.

Carbon-Storing, Long-Lasting
Sourced from the byproducts of lumber yard milling, our wood fiber insulation helps strengthen a sustainable forest economy while transferring the carbon-storing capabilities of wood into homes and buildings. With reduced carbon footprints, increased longevity, and enhanced efficiencies, homes and buildings using wood fiber insulation are healthier for people and the planet.
Carbon-Negative
Wood fiber insulation stores more carbon than is produced during the manufacturing process, and lowers a building’s upfront carbon footprint. A building insulation life cycle analysis shows that wood fiber drastically reduces carbon emissions compared to other materials during the manufacturing process, while in use, and after disposal or reuse.


Promotes Sustainable Forest Management
Because we use abundant residual softwood chips produced as byproducts of lumber yard milling, we’re helping support the sustainable forest management practices that have long been at the center of Maine’s heritage.


Helps Buildings Last Longer
Wood fiber insulation contributes to energy-efficient construction by delivering reduced thermal bridging, best-in-class resistance to short-term heat gains – even compared to higher R value insulations – and superior moisture management to prevent condensation, mold, and rot. Buildings constructed using wood fiber insulation can last longer, and store carbon in the built environment during their full lifecycle.

“Maine housing standards have been steadily ramping up the required amount of R value in the roof because this is one of the easiest places to add insulation, and this is where TimberHP has been really effective because it’s an easy drop-in. We’re also focused on good air sealing and controlling that attic lid so there isn’t moisture and air leakage through the ceiling that causes buildings to degrade.”

Supports Forestry and Community
Our advanced wood fiber insulation technology is breathing new life into the forest products industry, reinvigorating local communities. For decades, paper mills have been a major economic driver across the U.S., but, with less paper needed these days, many have been forced to close their doors. We revitalized a shuttered paper mill in Madison, Maine, and continue to step up, converting forest byproducts into cost-competitive, environmentally-sustainable insulation solutions.

Reduced Environmental Burden
Wood fiber insulation is free from harsh fibers, won’t off-gas, and is made from renewable woodchips. Transportation to our manufacturing facility is minimal compared to other products such as glass, sand, and chemicals for foam. Unlike other insulations that are derived from fossil fuels, our insulation is biogenic, non toxic, and biodegradable. Plus, we recycle off-cuts and out-of-spec material back into the manufacturing process, minimizing waste.
