FiberFill — our latest innovation in natural fiber insulation. Engineered from cellulosic fibers and made from FSC-certified wood chip residues, FiberFill is a carbon-negative blow-in insulation designed for high performance, safety, and environmental impact reduction.
Ideal for Builders and Architects
FiberFill is already being specified by leading builders and architects focused on sustainable construction materials. It’s recently been featured in industry publications like Building Enclosures and Walls & Ceilings, highlighting its growing adoption as a reliable whole-building insulation solution. ArchiExpo also featured Hempitecture family of products, including our efforts with NYSERDA to bring blow-in insulation to New York!
Why Choose Natural Fiber Insulation?
- Made from renewable, FSC-certified wood chips
- Stores CO² instead of emitting it
- Resists fire, mold, corrosion, and fungi
- Odorless, and safe to handle
High R-Value & Moisture Regulation
FiberFill offers an impressive R-value of 3.7 per inch, making it a top choice for energy-efficient construction. Its natural ability to regulate moisture enhances indoor air quality and building durability, while its non-toxic, VOC-free formulation promotes occupant health.
Superior Blow-In Performance
FiberFill is available in 11.3 kg (25 lb) compressed bags and designed for seamless, gap-free installation. Its micro-fibrillated cellulose fibers interlock during application to minimize settling:
- 48 kg/m³ density in closed cavities for maximum stability
- 24.4 kg/m³ density in open attics for cost-effective coverage
Applied with the same method and equipment as paper cellulose, without the debris and with reduced dust!
