Prevent sag and speed the construction process with humidity-resistant ceiling systems.

Armstrong HumiGuard^TM Ceilings:

Humidity-resistant products like Armstrong HumiGuard ceilings and hot dipped galvanized grid add value during and after the construction process.  Their performance enables contractors to install the ceiling before the building is enclosed and minimizes ceiling replacement after construction for longer term, sustainable design.

Additionally, HumiGuard ceilings aren't negatively affected by intermittent or seasonal facility use, where HVAC may be shut down for extended time frames.  Most mineral fiber HumiGuard ceilings are treated with BioBlock^TM paint containing a special fungicide that inhibits or retards the growth of mold or mildew on their painted surfaces. 

Virtually all other Armstrong acoustical panels provide acceptable humidity resistance for most conventional commercial building applications: the building is closed in; HVAC systems are functioning on an ongoing basis. 

This category of Armstrong ceilings provides validated performance required for all high humidity applications - just short of standing water, direct contact with water or exteriors.  These products can be installed earlier in the construction process (before the building is enclosed), wherever HVAC systems might be shut down, or in all high humidity applications other than out doors or where subjected to standing water.
