K-13 and K-13 High-R System

K-13 is a high-performance, spray-applied, thermal and acoustical finish system, consisting of natural, plant-based fibers, and specialty water-based adhesive. K-13 is spray-applied to substrates of ribbed metal decking, wood, concrete, gypsum/drywall, and can adhere to complex surfaces such as domes. Common applications include: restaurants, parking structures, gymnasiums, museums, recording studios, worship centers, classrooms, retail and more. The High-R System is a mechanically supported system for projects requiring a higher R-value. K-13 is efficiently spray-applied up to 10” thick to achieve up to R-37.5.
