Sustainable Performance | Durability

Did You Know. . .A high durability ceiling has a longer life cycle and allows for greater flexibility for facilities when spaces are re-purposed.
|
|
 |
| Ceiling systems which are more durable and damage-resistant, in addition to those that have various levels of cleanability,
minimize the need for frequent replacement and disposal.

Abuse Resistance
|
|
|
IMPACT RESISTANCE
|
 |
|
 Falling Ball Impact Test (Modified ASTM D 1037 Procedure) |
|
Ceilings in areas like school corridors or gymnasiums need to withstand abuse, including surface impact. The Falling Ball
Impact Test evaluates a ceiling's impact resistance.

SCRATCH RESISTANCE
|
 |
|
 Hess Rake Test |
|
In any areas where lay-in ceiling panels frequently need to be removed for plenum access, surface scratch resistance is highly
desirable. The Hess Rake Test evaluates surface scratch resistance.

texture ceiling.]

FREQUENT PLENUM ACCESS
|
| |
|
 Minimize Damage |
|
Downward access for Vector™ panels minimizes panel damage from hanger wires and other obstructions. See products with Vector™
edge detail, pages 35, 36, 55, 56, 131-134, 159-160.

Cleanability
|
|
|
SOIL RESISTANCE
|
 |
|
 Simulated Supply Air Diffuser Soiling Test |
|
Dirt accumulation not only detracts from a ceiling's appearance, but can cost money by requiring painting or replacement of
the ceiling. In addition to reducing acoustical efficiency, soiling can cause a substantial reduction in light reflectance.
Most Armstrong Hi-LR ceilings provide excellent soil resistance for lasting value and performance.
The Simulated Supply Air Diffuser Soiling Test evaluates this soil-resistant property.

WASHABILITY
|
 |
|
 Washability Test (ASTM D 4828) |
| Ceilings installed in laboratories, clean rooms, food preparation areas, and other sanitary applications are required to meet
washability standards. The Washability Test evaluates a ceiling's ability to withstand washing.
(left: These photos show the superior washability of Fine Fissured with VPO versus a standard ceiling.)

|
|
SCRUBBABILITY
|
 |
|
 Scrubbability Test (ASTM D 2486) |
| Ceilings installed in laboratories, clean rooms and food preparation areas are required to meet scrubbability standards -
and, sometimes, other specific criteria. The Scrubbability test evaluates a ceiling's ability to withstand scrubbing.
(left: These photos show the excellent scrubbability of VL versus a less scrubbable ceiling.)
