Warranty Conditions
All ceiling products must be installed and maintained in accordance with the Armstrong World Industries written installation and maintenance instructions
for that product in effect at the time of installation.
This warranty is not transferable and applies to the original purchaser only.
Prior to installation, the ceiling product must be kept clean and dry in an environment that is between 32° F (0°C) and 120°F (49°C) and not subject to
Abnormal Conditions. Abnormal Conditions include exposure to chemical fumes, corrosive agents (such as chlorine), vibrations, fi re, and water, freezing
temperatures, accident or any other form of abuse, or excessive dirt or dust buildup. If subject to Abnormal Conditions, where possible, the products should
be removed immediately and replaced once the conditions are normal.
Installation of the products shall be carried out where the temperature is between 32°F (0°C) and 120°F (49°C). It is not necessary for the area to be
enclosed and for HVAC systems to be functioning and in continuous operation. All wet work (plastering, concrete, etc.) must be complete and dry, and the
products must be protected from the elements such as rain, snow, etc. These systems cannot be used in exterior applications, or where standing water
is present due to high humidity, or where moisture will come in direct contact with the ceiling. These temperature and humidity conditions must be met
throughout the life of the warranty.

Microbial protection does not extend beyond the treated surface as received from the factory, and does not protect other materials that contact the treated
surface such as supported insulation materials. General maintenance guidelines can be found at ceilings.com.
