K-13 HIGH-R SYSTEM
K-13 Spray-Applied Thermal and Acoustical Insulation is an exposed ceiling finish 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.
HOW IT WORKS
PERFORMANCE & EFFICIENCY
With a mechanically supported system, K-13 High-R decreases risk for fallout found with typical high-build installations that require higher R-Value requirements for your project.
The K-13 High-R System begins with installing stickpins to the substrate and applying the first layer of K-13 up to 5” thick. This first layer of insulation is secured in place using StructaLath III, a unique welded lath wiring. The second layer of K-13 is then applied to meet project specifications for R-Value and color.

STEP 1
Install 6” stick pins starting 3” from wall in an approximate 16”x16” grid-like pattern.

STEP 5
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.
With the K-13 High-R System, K-13 is applied up to 10” to meet your higher thermal requirements, making it ideal for projects such as Parking Garages, Event Centers, Pre-Engineered Metal Buildings, or Stadiums.

SUSTAINABILITY
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.
