FiberFill cellulosic natural insulation is a high-performance thermal and acoustic insulator. It has a uniform consistency, is odorless, and is made entirely from cellulosic fibers. Designed for seamless, gap-free insulation, its interlocking fibers ensure stability with a blow-in density of 2.99 lb/ft³ in walls, and 1.5 – 1.9 lb/ft³ for attics, ceilings and floors, minimizing settling.
Formulated for fire, fungi, and corrosion resistance, ensuring a safe and eco-friendly insulation solution.
A dimensionally stable and homogeneous product, allowing it to fill cavities between studs seamlessly without gaps. Adsorb and release moisture while maintaining its insulating performance, helping to regulate indoor humidity levels naturally.
FiberFill offers exceptional soundproofing in accordance with ASTM C423 standards with an NRC and SAA rating exceeding 0.75.
Just better
FiberFill is a renewable, eco-friendly insulation that actively stores CO² throughout its life cycle. Its carbon-negative footprint contributes to a healthier planet, making it an environmentally responsible choice for sustainable construction.
This is why we have engineered FiberFill: to make homes healthier, more sustainable, and to have less impact both on our own indoor environment, as well as our planet.
An effective R-value of 3.7 which contributes to thermal energy performance.
Its dense, fibrous texture effectively absorbs sound, reducing noise transmission and enhancing acoustic comfort in residential and commercial spaces.
Its hygroscopic properties enable it to adsorb and release moisture while maintaining its insulating performance, helping to regulate indoor humidity levels naturally.
Actively reduces the planet’s carbon footprint, making it a truly sustainable choice for modern construction.
