Insulation for Hospitals Insulation solutions uniquely suited to the IAQ needs of hospitals, medical centers and healthcare facilities 

The selection, installation and maintenance of insulation can have a dramatic impact on the long-term performance and cleanliness of a mechanical system in healthcare space. Armacell offers a comprehensive line of fiber-free, elastomeric foam solutions that safeguard the thermal efficiency of these systems without compromising the IAQ standards such facilities demand. 

Armacell solutions include:

These products are the most reliable and durable insulation materials a healthcare facility can choose. Properly installed, Armacell’s 100% fiber-free elastomeric foam insulations meet the toughest standards in terms of lAQ while helping hospitals avoid costly downtimes associated with premature failure of less-durable materials.Insulation for Healthcare 

Better Moisture Control for Prevention of Bacterial Growth

Armacell’s non-absorptive elastomeric foam insulation effectively keeps condensation from occurring in cold water and HVAC systems. On the other hand, the moisture vapor barriers that are required on fibrous insulations can fail, leaving them susceptible to moisture and mold growth. Moisture absorption also degrades the thermal efficiency of the insulation.

Properly applied, Armacell insulating materials are far less vulnerable to the occurrence of moisture, and therefore mold.

  • Closed-cell foam structure prevents moisture from wicking; it can’t be compromised by surface punctures or tears

  • No separate moisture-vapor retarder needed. The closed-cell structure is like having a jacket built right in.

  • Better long-term thermal efficiency.  Moisture causes fibrous material to compress and lose its thermal effectiveness; non-permeable insulation stays dry and therefore retains its thermal integrity

  • Made with exclusive Microban® antimicrobial protection; resists the growth of mold and mildew

Better Efficiency Keeps High Ticket HVAC Systems Performing Affordably

Moisture compromises efficiency! For every 1% moisture gain in the insulating material, there is a 7.5% loss in thermal efficiency. That’s why AP Armaflex’s closed-cell structure is so valuable to the efficiency of a cold system. It blocks moisture, therefore it maintains its thermal integrity.

When the vapor jacket of open-cell insulation is damaged, the insulation can reach saturation relatively quickly due to wicking, resulting in very high thermal K values. This equates to a loss in costly cooling BTU’s.   

Better IAQ for Patients and PersonnelInsulation for Healthcare

Fiber-free ducts are fast becoming the norm in healthcare facilities. 

  • Fiber-free AP Armaflex, AP Coilflex and AP Spiralflex are non-particulating, therefore the material will not break apart and become airborne

  • Low VOCs – With AP Armaflex there is no off-gassing; GREENGUARD® Gold Certified to low emission standards

  • Does not support the growth of mold and mildew on the insulation material even if it becomes wet

Easier to clean. Dust and dirt in an HVAC air duct can turn into more serious problems if left unattended.

Unfortunately, most healthcare facilities do not have the maintenance staff necessary to keep their HVAC systems clean, therefore the best choice is an insulation that won’t trap dust and dirt. All Armacell foam insulation has a smooth, non-porous surface that resists dirt and dust, and also is easy to clean.

Non-cellulous materials prevent fungal growth. Literally any organic material – including the cellulose used in the separate vapor retarders of some insulation – can provide a food source for mold. Elastomeric foam is not a suitable nutrient for mold, therefore does not support its growth.

Acoustical bonus. In addition to all the above benefits, Armacell’s elastomeric foam insulation has excellent acoustic properties as a duct liner or wrap in HVAC systems. The foam can absorb noise from the system and dampen structure-borne vibrations from the ductwork, fans or motors. This ensures a quieter healthcare environment, especially where low-frequency noise is a potential problem.

  • Reduces HVAC noise levels through sound absorption and blocking

  • Good NRC value (up to 0.60), excellent STC (Class 25)

  • Dense enough to provide excellent sound deadening (vibration damping) of HVAC rattle in metal ducts

What Experts Say About Keeping Duct Systems Healthy

While many argue the degree to which mold, dust and dirt in ductwork affects the health of building occupants, healthcare providers prefer to err on the side of a cleaner, fiber-free system.  They are not alone in their support for drier, particle-free duct systems:

“Porous materials such as internal fibrous glass liner have been identified as a major source of fungal contamination.”
ASHRAE Journal, April 2004


“…the very properties that make duct board and duct liner superior insulators (e.g. a fibrous structure with large surface area that creates insulating air pockets), also makes them capable of trapping and retaining moisture if they do get wet….”
U.S. Environmental Protection Agency

“When talking about water damaged insulation, the rule of thumb that is often followed is the same with any porous material including duct liner, sheet rock or carpeting… If these materials get wet and remain wet for more than 48 hours, they should be removed.”
