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 heating, ventilation and air conditioning (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 Stainless Steel PRELUDE

suspension systems. For swimming pools, install only with Aluminum PRELUDE Plus Suspension system. For outdoor

soffits, canopies, and parking garages install with PRELUDE

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.
