K-13 and SonaSpray "fc"

K-13 and SonaSpray "fc" are each products by the International Cellulose Corporation. The difference between the two is that K-13 functions as both an insulation material and an acoustical treatment, while SonaSpray is just an acoustical treatment.

K-13 is a spray-applied insulation that can be customized to your specific project requirements. Customizable aspects include R-value, noise reduction, condensation endurance, color, and texture. It can be applied to virtually any surface including wood, steel, concrete, and glass. K-13 material can be sprayed up to five inches thick without mechanical support. The K-13 product is the final exposed finish for wherever it is applied, and it may be colored to match the customer's preference.
