What Our Warranties Mean
Our warranties are our promise to you that the 
Armstrong
® 
ceiling and Armstrong installation materials 
you’ve purchased will be free from manufacturing 
defects. Because our products are designed 
and engineered to be used together for the best 
performance possible, we warrant that Armstrong 
ceilings and Armstrong installation materials, if used 
together, will be free from manufacturing defects as 
outlined below.
Please read all of the following terms carefully as this 
warranty may be affected by installation methods and 
materials used and site conditions. Armstrong does not 
authorize any person to assume or extend any other 
warranty obligation or liability on its behalf.
What will Armstrong do?
If a manufacturing defect does occur within the terms 
and conditions of this warranty, you will be supplied with 
new material to replace the defective ceiling product, 
the replacement materials will be of the same or similar 
design and quality.
What does this warranty not cover?
• Damage that may occur due to Abnormal Conditions 
described above is not covered by this warranty. 
• This warranty does not cover damage caused by 
improper maintenance, improper installation, or by 
use contrary to our recommendations, such as use 
outdoors or on surfaces other than ceilings.
• This warranty does not cover normal wear and tear 
or shade changes due to exposure to smoke, fumes, 
leaks, or abuse.
• This warranty does not cover labor charges to 
replace obvious visual defect in the material at time 
of installation. 
• We exclude and will not pay any consequential or 
incidental damage, loss or expense other than to the 
ceiling system itself.

original purchaser only. It does not apply to materials

repainting panels. All warranties will be voided by fi eld 
painting.

The Armstrong ceiling products listed above are 
warranted to be free from defects in materials or factory 
workmanship for 30 years from the date of installation 
when installed using an Armstrong suspension system 
and used under normal conditions. If these products 
are not installed using an Armstrong suspension 
system the Armstrong ceiling products listed above are 
warranted to be free from defects in materials or factory 
workmanship for 10 years from the date of installation 
when installed under normal conditions. (Except for 
obvious defects in materials or factory workmanship, 
which Armstrong must be notifi ed of within 30 days of 
the date of installation.)
Armstrong suspension systems are warranted to be 
free from the occurrence of 50% red rust as defi ned by 
ASTM D610 test procedures for 30 years from the date 
of installation, when installed with the Armstrong ceiling 
panels listed above and in accordance with Armstrong’s 
written installation instructions. 
Warranty Conditions
All ceiling products must be installed and maintained 
in accordance with Armstrong’s 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.
Sag Resistance
The Armstrong ceiling products listed above have extra 
sag resistance. They are warranted to be free from 
defect in materials or factory workmanship or sagging 
and warping as a result thereof for thirty (30) years from 
the date of installation, when installed with Armstrong 
suspension systems; for ten (10) years from date of 
installation when an Armstrong suspension system is 
not used. 
Mold and Mildew Resistance
 The Armstrong ceiling products 922 Fine Fissured, 928 
Fine Fissured, 932 Fine Fissured, 1728BL Fine Fissured 
Black, 271 Sahara, 273 Sahara, 241 SuperTuff, and 954 
Classic Fine Textured have bioblock treatment. They are 
warranted to be free from the growth of mold, mildew 
and gram positive and gram negative odor and stain 
causing bacteria for thirty (30) years from the date of 
installation, when installed with Armstrong suspension 
systems; for ten (10) years from date of installation when 
an Armstrong suspension system is not used. 
Armstrong fi berglass ceiling panels listed above do 
not have bioblock treatment, but are warranted to be 
free from the growth of mold, mildew, and odor and 
stain causing bacteria for 30 years from the date of 
installation, when installed with Armstrong suspension 
systems; for ten (10) years from date of installation when 
an Armstrong suspension system is not used, due to 
the inherent characteristics of the products. 
This limited warranty is subject to further conditions 
listed below. 
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. General maintenance guidelines 
can be found at www.armstrong.com.
The warranty is void if the ceiling product is not installed 
in accordance with the installation instructions included 
in every carton, also available at www.armstrong.com
