Thermal and Acoustic Solutions for Stadiums

Key Elements

Determining the appropriate thermal and acoustic solutions for stadiums and multi-purpose arenas can be a challenging task that demands careful consideration of both form and function for a meaningful, effective execution. Architects and contractors must thoroughly comprehend the desired, long-term functionality of a completed project before making a decision. 

The proper management of stadium temperature is essential, as large volumes of people gather together to enjoy concerts, sporting events, conferences, and more. Effective thermal insulation ensures stadium suites and interior spaces are protected from exterior weather. 

Additionally, acoustic solutions for stadiums and multi-purpose arenas are essential for controlling reverberation and echo from music, announcements, and crowd volume, while wanted sounds are amplified effectively. 

International Cellulose Corporation is proud to offer quality products that support ultimate thermal and acoustical comfort for fully functional stadiums personalized for your needs.

Product Highlights


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

Thermal Control

K-13 is sprayed-in-place, filling cracks, seams, and voids to form a monolithic coating over the substrate which helps 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 3.70 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.



Ure-K is a spray-applied 15-minute thermal barrier approved to go over exposed applications of polyurethane foam in existing buildings and new construction projects as a combination system to meet mandatory code requirements. Ure-K is not foam insulation.

K-13 High-R System

The K-13 High-R System is a mechanically supported insulation system for projects requiring a higher R-Value. With this system, K-13 is efficiently spray-applied up to 10" thick, achieving up to R-37.5 to meet specifications.

Typical Projects

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. Surfaces to receive K-13 are to be inspected prior to installation to determine if pre-treatment is required.
