Good insulation turns your home into a warm, cozy haven. Yet when exposed to fire, some insulation materials can ignite in an instant, turning a comfortable home into a dangerous scene.
Today, the fire performance of many traditional insulation materials on the market remains a serious concern. They are inherently flammable and spread fire rapidly. Even with added flame retardants, their effectiveness fades over time, leaving safety risks. It often feels as if we have to choose either warmth or safety.
But Longou’s flame‑retardant spray‑on cellulose insulation breaks this compromise. It is an advanced insulation material that combines exceptional thermal retention with outstanding fire resistance. It is more than just a “warm coat” for your building — it is a full‑body fireproof armor. Easy to apply with a simple spray, it forms a seamless layer that tightly adheres to walls, locking in heat, reducing noise, and improving comfort.
Most importantly, this fiber features stable, long‑lasting flame‑retardant properties. Under high temperatures, it does not burn easily, does not melt or drip, and does not spread fire quickly, drastically reducing fire risks at the source. Its protective performance far exceeds most other insulation products available today.
Natural & Eco-Friendly
ECOCELL® cellulose fiber is made from renewable natural raw materials, making it a truly eco-friendly building material. It contains no harmful substances such as asbestos or fiberglass, eliminating health risks from the material itself at the source.
All-in-One Performance: Fire Resistance, Thermal Insulation & Sound Insulation
Longou’s cellulose fiber can be sprayed directly onto building substrates to provide excellent thermal and acoustic insulation. It can also be injected into wall cavities, forming a tight, seamless protective system with no dead corners.
Superior Fire Resistance: Specially treated for flame retardancy, the cellulose fiber quickly forms a dense, protective barrier when exposed to fire. This barrier blocks oxygen, slows the spread of flames, and buys valuable extra time for emergency rescue. Tests have proven that it maintains its structural integrity under high temperatures — without collapsing or supporting combustion.
Efficient Thermal Insulation: Once sprayed onto walls, the cellulose fiber forms a dense, uniform layer that effectively stops air convection. It locks in heat during winter and blocks hot air in summer, helping buildings significantly reduce energy consumption and utility costs.
Exceptional Sound Insulation: Compared with traditional acoustic materials, Longou’s cellulose fiber delivers superior noise reduction, with a Noise Reduction Coefficient (NRC) as high as 0.85. It effectively blocks outside noise, creating more comfortable rest areas and quieter working spaces.
