Celbar System

Grupo Eleven Solutions® provides advanced thermal and acoustic insulation services utilizing the Celbar System, formulated from recycled cellulose fibers treated with specialized fire-retardant chemicals. Engineered to address noise transmission and excessive reverberation in hospitality, industrial, and commercial venues, this solution creates a seamless protective barrier. Applied with modern projection machinery, the system delivers superior sound dampening alongside dependable thermal performance across structural walls and open ceilings, enhancing comfort for guests and staff alike.

Our professional spray-applied insulation turns echo-prone architecture into acoustically balanced, energy-efficient environments. Carried out by personnel certified by manufacturers, our installations ensure consistent adhesion on varied substrates without sagging or settling. By controlling harsh acoustic reflections, the system enhances speech intelligibility and auditory privacy across dining rooms, auditoriums, and corporate facilities. Backed by national and international certifications, it represents a dependable choice prioritizing passenger safety, fire protection, and acoustic comfort.

What is the Celbar System and How Does It Work?

The Celbar System is a specialized spray-applied thermal-acoustic insulation composed of recycled cellulose fibers integrated with fire-retardant chemistry. Propelled through pneumatic spray equipment alongside an adhesive binder, it bonds directly to concrete, steel decking, wood, and drywall. The material fills micro-crevices and eliminates acoustic bridging. Its porous fiber matrix absorbs airborne sound waves, dampening mechanical noise, speech reverberation, and structural echo throughout the treated interior environment.

Beyond its remarkable sound absorption, the system acts as an effective thermal boundary. Its tightly packed cellulose structure traps static air, restricting heat flow through building envelopes and reducing climate-control demand. Fire-retardant additives provide crucial passive fire resistance, making it suitable for exposed ceilings and occupied public areas. The combination of thermal control, noise mitigation, and fire safety makes it an exceptional choice for modern commercial engineering.
