Feature 04, VOC Reduction -
A precondition for all three project types, this feature is essential to achieve for a WELL Building Certification. Volatile Organic Compounds (VOCs) can cause indoor air pollution from the leaching of paints, finishes, cleaning equipment, and various other products. This can cause irritation to building occupants and in some cases serious illnesses.
Insulated metal panels are considered a closed assembly, which means VOCs cannot leak. In addition, many of the larger IMP manufactures have published statements regarding their VOC
position. For example, Kingspan’s PIR and QuadCore products are GREENGUARD Gold certified which states they have zero VOC emission levels.
In addition, this manufacturer can supply the project with low/zero VOC emitting butyl sealant which would further contribute to part 4 of this feature.
Feature 12, Moisture Management
Moisture intrusion can create serious problems which will lead to poor heath of the building occupants. Mold, poor indoor air quality, and mildew are to name a few.
Let’s look at the applicable parts:
Part 3: Condensation Management
Insulated metal panels offer vapor management strategies through their dual steel skins. Condensation is not possible within the IMP assembly due to the use of “closed cell foam” and the air impenetrable joinery. In addition, since the inner steel skin’s temperature would be above the dew point, condensation is not an issue. This would also help address the required narrative in Part 4: Material Selection and Protection of this feature.
Feature 14, Air Infiltration Management
An optimization for all three project types, this feature can help a team achieve higher levels of WELL Certification such as Gold or Platinum. As the feature states, a leaky building envelope can lead to problems such as mold, air pollution, or even pests.
The beauty of using IMPs is that the water, air, vapor, and thermal control layers all combine into one assembly. In addition, factory built in joinery, gaskets, and concealed caulk placement creates an exceptional air and weather tight building envelope.
