Warranty Guide

Warranty Conditions
All ceiling products must be installed and maintained in accordance with Armstrong written installation instructions for that product in effect at
the time of installation and best industry practice. 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.
For HumiGuard Plus: 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 or for HVAC systems to be functioning. All wet work (plastering, concrete, etc.) must be complete and dry.
For HumiGuard Max: HumiGuard Max’s sag performance warranty extends to installations where the ceiling product is exposed to chemical
fumes, extreme temperatures up to 120° F (49° C) (including steam up to 275° F (135° C)) and 100% RH, including standing water applications
so long as the product is installed with either SS PRELUDE PLUS, AL PRELUDE PLUS or PRELUDE PLUS XL Fire Guard suspension systems.
For swimming pools, install only with AL PRELUDE PLUS Suspension system. For outdoor soffits, canopies, and parking garages install with
PRELUDE XL for Exterior Applications (wind uplift should be considered).
HumiGuard Max and HumiGuard Plus: The ceilings must be maintained to avoid excessive dirt or dust buildup that would provide a medium for
microbial growth on ceiling panels. 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.

How does state law apply?

allow exclusion or limitation of incidental or consequential damages or limitations on how long an implied warranty lasts, so the limitation
or exclusion herein may not apply to you.
