Acoustical Performance

Protek-13® provides a protective coating for your fibrous surfaces without significantly affecting the acoustical performance of the material underneath. The following test was conducted by spraying two separate thicknesses of Protek13® over 1.75" of K-13® Spray-On thermal/acoustical insulation. System 1 was applied in a standard coating, covering 96-98% of the K-13 underneath. System 2 was a heavy build, covering 99-100% of the underlying K-13®. The following chart shows the acoustical performance of both systems.

Frequency 125 250 500 1000 2000 4000 NRC
1.75" K-13 0.19 0.60 1.05 1.11 1.03 0.98 .95
Standard 0.30 0.60 1.09 1.09 1.02 0.95 .95
Heavy Build 0.32 0.53 0.69 0.56 0.36 0.29 .55

Protection from Physical Damage

High traffic areas are often vulnerable to physical damage from personnel, machinery, birds and other sources. The tough resilient surface of Protek-13® resists abrasion and prevents the "picking away" of the fibers. This protection can greatly extend the useful life of the covered building materials.

Protection for airborne Contaminants

Dust, dirt, grease and fumes are present in almost every industrial environment. The firmer, more uniform surface of Protek-13® significantly reduces the accumulation of these airborne contaminants. In addition, Protek-13® can easily be swept with a broom, blown clean with compressed air or lightly washed with water (no scrubbing).

Solid Fire Performance Ratings

Protek-13® has a Class 1, Class A flame spread rating of 5 according to ASTM E-84.

High Light Reflectivity

The application of Protek-13® can brighten your whole facility. This high light reflectivity greatly improves the safety of the working environment without requiring an increase in lighting power.

Colorful Options

Fibrous or porous substrate materials will absorb a great deal of regular paint without showing a significant color change. Protek-13®, due to its bridging and interlacing fibers, provides an easily obtainable uniform color (at the surface) requiring less material. If a custom color is desired at the time of installation, Protek-13® can be custom blended to match your design color scheme.

Celbar is a blend of specially prepared cellulose fibers, organic in nature, treated with adhesive and fire resistant chemicals. When sprayed in place, the interlocking fibers result in a mass that produces excellent sound and thermal properties. Celbar is pneumatically spray-applied in wall and floor/ceiling cavities to form a monolithic coating.

K-13 insulation is the spray-applied cellulose insulation tailored to your specific project requirements for insulation (R value), noise reduction (NRC), color, durability, condensation control, texture, and aesthetics. In addition, it usually provides these features at lower installed prices than many common systems such as rigid board and batt insulations, sprayed plasters, and acoustical ceilings.
