K-13 Thermal & Acoustical Finish


CSI: 07 21 29 • 09 83 16

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

A Total System

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.

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 3.75 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.


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.


Custom Colors Available

K-13 is available in seven standard colors as well as specially-matched custom colors.

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 PCB’s.

Technical Data


Condensation Control

K-13 aids in condensation control in projects such as ice arenas and indoor pools. The proper combination of K-13 and ventilation prevents condensation on metal, concrete, and other surfaces reducing ventilation requirements and operating costs.

Substrate Compatibility

Our patented water-based adhesive adheres to virtually any properly prepared substrate and ceiling configuration including metal deck, barrel-vaults, concrete "T" corrugated decks, gypsum, wood, concrete, and other complex surfaces.

K-13 Over Fireproofing

K-13 is UL Approved and listed in (6) UL BXUV Guide Design Assemblies as allowable sprayed fiber for application over Spray-Applied Fire-Resistive Materials.

The following roof, floor, and beam UL® Design Assemblies include both K-13 & SonaSpray “fc”:
D779, D798, D925, D985, P725, P732
