Armacell in Academics

Specifying Armacell solutions for a school or university building’s mechanical systems is fundamentally smart. Either in construction or renovation, our insulation products and accessories are trusted by schools around the world. The fiber-free, formaldehyde-free, and low VOC formulation in our foam insulation provides energy efficiency, protects against condensation, and preserves indoor air quality making it the correct choice for any learning environment. Armacell in action.

A Study of Properly Insulating Mechanical Systems

Schools and universities represent 12% of nonresidential building construction in the United States. Whether the students are K-12 or scholars in higher learning, all educational buildings need to have high-performing HVAC and plumbing systems. Installing insulation on chilled water systems, HVAC ducts, boilers, or plumbing piping is a simple facility upgrade that can improve energy performance, control condensation, protect indoor air quality (IAQ), and provide acoustic control creating a more effective learning environment. Armacell’s innovative insulation solutions for schools and universities make us first in our class.


In a typical school building, heating, cooling, and lighting account for nearly 70% of all energy use. Even though this energy use accounts for only 4% of a school district expenditure, it’s an area where administration can easily make improvements in energy efficiency by insulating or upgrading mechanical systems. Avoiding inefficiencies and unnecessary maintenance can be achieved by properly insulating ducts, vessels, boilers, and pipes to help reduce energy waste. Even with proven benefits, adoption of newer HVAC and plumbing technologies in education facility construction can be slow due to budget constraints. This hesitancy to upgrading older systems has recently been offset through targeted legislature and government policies which focus on energy use in schools. These include the Infrastructure Investment and Jobs Act (IIJA), American Rescue Plan Act (ARP), the 2021 Coronavirus Response and Relief Supplemental Appropriations Act (CRRSAA), the Inflation Reduction Act, and the recent Build America, Buy America Act (BABAA). Additionally, applicable U.S. Department of Education Infrastructure Grant Program may provide tens of billions of dollars in new funding to U.S. K-12 public schools for facility and transportation improvements. Strategic use of this funding can help remedy historic school systems, reduce energy expenditures, and help schools lead the nation in solving the climate crisis.


Cold-water and air-handling systems on education campuses are prone to moisture issues as both systems are likely to develop condensation problems if not insulated or if the insulation is not sized or installed correctly. Controlling condensation is critical because moisture can compromise a mechanical system and its insulation, leading to thermal loss and costly repairs. In the event that there is a moisture issue, even a small 4% moisture ingress can reduce insulation effectiveness by 70%! Even worse, if this moisture goes unnoticed, corrosion under insulation (CUI) erodes the pipe surface over time, causing pipe failure or resulting in need for replacement – an unnecessary hit to schools’ budgets and tight resources. This is why it is critical for education facilities to focus their attention on controlling condensation on their systems. A closed-cell foam insulation product has the structure to prevent moisture from wicking and does not require a separate moisture-vapor retarder. Armacell’s AP ArmaFlex solutions are also made with exclusive Microban® antimicrobial protection to resist mold and mildew growth.


Preserving IAQ in schools is mandatory which is why they require a contaminant and fiber-free environment. IAQ is especially important in ductwork, where fibrous material can get caught up in the air stream exposing school occupants to airborne particulates. Insulation on ductwork can either help defend against or contribute to indoor air-quality problems. This is particularly true of school air-handling systems in which the insulation needs to resist moisture while ensuring that the air passing over it remains mold-, dust- and fiber-free for students. The same requirements also apply to insulation used over hot and cold piping systems inside education facilities. While insulation’s primary purpose is thermal efficiency, the wrong product could particulate fibers or off-gas volatile organic compounds (VOCs) into the indoor air, creating poor breathing conditions. Other insulation materials can absorb moisture, supporting the growth of mold and mildew. Any of these problems will significantly degrade the indoor learning environment so it is important to choose an insulation solution that is Greenguard® Gold Certified, has low VOCs, no off-gassing, and is fiber-free and non-particulating to protect IAQ in schools.


Many acoustical problems can arise in classrooms such as background noise, loud voices, reverberation, and mechanical disturbances. As 60% of classroom activities utilize spoken communication, it is easy to understand that noise can be distracting enough to cause speech intelligibility for students trying to listen to instruction. In the U.S. alone, classrooms can typically have speech intelligibility ratings up to 75%, which means every fourth word is not heard or understood. Children with learning disabilities or those who speak English as a second language are especially at risk for not being able to hear effectively if classrooms, auditoriums, libraries, and even hallways are not quiet. This is a communication concern that must diligently be addressed through soundproofing advances and acoustical solutions like elastomeric foam insulation and mechanical thermal decoupling acoustical tape, to ensure learning transfer is occurring in quieter classrooms. 


Armacell continuously works to improve our products with advanced testing standards to ensure they meet strict building codes, and state codes and regulations, as well as the requirements from organizations like the International Energy Conservation Code (IECC) and ASHRAE, which develop model building codes and performance standards. For school applications requiring flame and smoke ratings, many of our solutions are plenum-rated and meet ASTM E 84 at 25/50 for up to 2” thicknesses. ArmaFlex Ultra® is the first elastomeric insulation Classified by UL to UL 723 at flame/smoke rating of less than 25/50. While our products meet many compliance standards 

it is important to note that building codes can vary from state to state and municipality, so specifiers and installers should be sure to select products that are compliant in their region.
