K13 Sound Absorption Spray

CSI: 07 21 29 • 09 83 16

K-13 is a spray-applied acoustical insulation typically used as an exposed ceiling finish requiring no additional barriers or materials. K-13 meets project requirements for noise control with an attractive natural texture that is available in standard and custom colors.

Sound Control

The K-13 sound absorption spray system begins with specially prepared cellulose fibers combined with natural fire retardants in a strict, quality-controlled manufacturing process to produce a Class 1, Class A 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.

K13 is a thermal and acoustical insulation. Contact us today for any additional information!

THERMAL CONTROL

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 3.7 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.

SoUND CONTROL

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.

K-13 in White

CASE STUDY →

Designed by Gensler, Jet Support Services, Inc.’s Chicago office creates a modern, flexible workplace that supports collaboration, productivity, and employee well-being. To enhance acoustic comfort throughout the open-concept environment, K- 13 in White was applied to the exposed ceilings, absorbing excess noise and reducing reverberation. Its high light reflectance also helps maximize natural daylighting, creating a brighter and more inviting workspace, while GREENGUARD Gold certification supports healthy indoor air quality.

SUSTAINABILITY

K-13 is made from 80% Pre-Consumer Recycled Content and inventoried to 1,000 PPM in accordance with the HPD Collaborative.

K-13 is UL GREENGUARD Gold certified and compliant with LEED v4: Low-Emitting Materials, CDHP/California Section 01350, SCAQMD Rule 1168, and CHPS – Acoustical Ceiling. Additionally, K-13’s thermal and acoustical performance may contribute to sustainable credit categories for green-building initiatives.

K-13 does not contain silica dust, asbestos, mineral or glass fibers, or PCBs.
