Description
Spray-applied K-13 cellulose insulation achieves objectives in terms of insulation, noise reduction, durability, condensation control and aesthetics.
UNITS PER SKID: 24
Material Use:
K-13 is a spray-applied cellulose-based thermal and acoustical insulation finish designed for use on ceilings and overhead surfaces. It serves as both an insulation layer and an exposed finish, offering excellent sound absorption and thermal resistance. With an R-value of 3.75 per inch, K-13 is ideal for enhancing energy efficiency and acoustic performance in a wide range of commercial, institutional, and industrial environments.
System Components:
K-13 is a single-component system composed of cellulose fibers combined with a proprietary adhesive binder. It is applied using specialized spray equipment by licensed contractors. The system does not require additional topcoats or sealers, although surface preparation and priming may be necessary depending on the substrate. K-13 is compatible with a variety of substrates including metal decking, concrete, wood, and gypsum.
Applications:
K-13 is suitable for interior and covered exterior applications where thermal insulation and sound control are required. Common applications include:
- Exposed ceilings in commercial buildings
- Parking garages and covered decks
- Auditoriums, gymnasiums, and theaters
- Industrial facilities and warehouses
- Open-plan offices and educational institutions
Application Details:
K-13 must be applied by certified contractors using approved spray equipment. The material conforms to complex ceiling geometries and adheres to properly prepared substrates. Surface inspection and potential pre-treatment are required before application. The average application thickness ranges from 1” to 5”, with corresponding R-values from 3.75 to 18.75. The material is applied in a monolithic layer and will exhibit some texture and thickness variation due to the nature of the spray process.
Special Notes:
- Environmental Conditions: K-13 is intended for interior and covered exterior use only. It should not be exposed to direct weathering or prolonged moisture without protection.
- Fire Rating: Class 1/Class A per ASTM E84 with a flame spread of 5 and smoke development of 5.
- Acoustic Performance: K-13 provides excellent sound absorption with NRC values up to 1.05 depending on thickness and substrate. For example, a 2” application on solid backing achieves an NRC of 1.00.
- Light Reflectance: Varies by color; white offers the highest reflectance at 84+, while black is lowest at 17+.
- Sustainability: Contains 80% pre-consumer recycled content and is UL GREENGUARD Gold Certified for indoor air quality. It contributes to LEED v4 credits in categories such as Indoor Air Quality and Thermal Comfort.
- Health & Safety: Free from silica dust, asbestos, mineral or glass fibers, and PCBs.
- Code Compliance: Complies with ASTM standards including C423, C518, C739, E84, and others. Approved by Factory Mutual, UL, and various local jurisdictions including Miami-Dade County and Los Angeles.
Limitations:
- UV Stability: K-13 is not UV stable and should not be used in areas exposed to direct sunlight unless protected.
- Moisture Sensitivity: Not intended for direct exposure to water or high humidity environments without additional protection.
- Thickness Limits: Minimum recommended thickness is 1”, with applications up to 10” possible depending on performance requirements.
- Installation Temperature: While not explicitly stated, standard practice for spray-applied cellulose materials suggests application in temperatures above 50°F (10°C) and in dry conditions to ensure proper adhesion and curing.
Coverage & Yield:
Coverage varies based on thickness and substrate. For example, at 1” thickness, the R-value is 3.75, and the NRC is 0.80 on solid backing. Specific coverage rates in ft² per bag or per gallon are not provided in the TDS and should be obtained from the manufacturer or installer based on project-specific conditions.
System Compatibility:
K-13 is a standalone system and does not require additional base coats or topcoats. However, it may be used in conjunction with compatible primers or sealers if substrate conditions require it. Always consult with the manufacturer or licensed installer for substrate-specific recommendations.
