K-13 Thermal Insulation
CSI: 07 21 29 • 09 83 16
K-13 thermal insulation is a spray-applied thermal and acoustical insulation typically used as an exposed ceiling spray insulation, requiring no additional barriers or materials. K-13 meets project requirements for thermal insulation, noise control with an attractive natural texture that is available in standard and custom colors.
Thermal Insulation Spray
The K-13 system begins with specially prepared cellulose fibers combined with natural fire retardants in a strict, quality-controlled manufacturing process to produce a Class A, Class 1 rated material. K-13 is then spray-applied by an international network of professional contractors licensed by ICC to ensure consistent and predictable results. During application, the K-13 fibers combine with a patented water-based adhesive resulting in a durable, exposed finish.
K-13 is sprayed-in-place, filling cracks, seams, and voids to form a monolithic coating over the substrate helping to reduce air infiltration. Unlike prefabricated insulations, K-13 has no voids or compressed areas to reduce thermal efficiency, resulting in exceptionally low heat-loss characteristics and an R-Value of 3.75 per inch.
K-13 can be sprayed up to 5" thick in one application without mechanical support. For an even higher R-Value, we recommend the K-13 High-R System, a mechanically supported system for R-Values exceeding R-19.
K-13 reduces excessive noise often present in modern design trends, significantly improving ambient sound quality and speech intelligibility.
K-13's superior acoustical performance is measured using the room reverberation method per ASTM C 423 to calculate a noise reduction coefficient (NRC). The resilient fibers of K-13 absorb sound energy instead of reflecting it, effectively reducing reverberation time and making it the perfect solution for noisy environments like restaurants, entertainment venues, or open-office plans.
Custom Colors Available
K-13 is available in five standard colors as well as specially-matched custom colors.
