q & a
-
Why is LR important?
When the proper type of lighting fixture is used with a high LR ceiling, there can be savings in both initial construction costs as well as long-term energy costs. The concept is to use the ceiling to reflect light back into the occupied space.
-
What does LR stand for?
LR stands for light reflectance. It is a measure of the percentage of light which is reflected off of a given panel surface. Typically, the whiter and smoother the ceiling panel, the higher the LR value.
-
When referring to ceiling panels, what is the meaning of type, form and pattern?
These categories refer to ASTM Test E 1264.
Type refers to the base material of the panel.
Form refers to the manufacturing process of the panel.
Pattern refers to the type of texture or pattern in the panel. -
What is the difference between Class A and Firecode® branded materials?
Class A signifies that a panel attained a flame spread index of 25 or less (based on 100 for untreated red oak) when tested in accordance with the Standard ASTM E 84. The Firecode® brand signifies that the panel has been classified as a protective membrane in a floor-ceiling or roof-ceiling assembly in accordance with the Standard ASTM E 119. All Firecode® protective membranes offered by USG have attained a Class A rating.
-
How many acoustical panel types does USG offer?
USG offers four major types of acoustical panels as well as Gypsum based panels for special applications. They are: Wet-Felted, Cast, "X" Technology and Fiberglass.
-
How far in advance can I order ceiling panel before installation?
Storage time of materials at the job site should be as short as possible, and environmental conditions should be as near as possible to those specified for occupancy. Excess humidity during storage can cause expansion of material and possible warp, sag, or poor fit after installation. Chemical changes in the mat and/or coatings can be aggravated by excess humidity and cause discoloration during storage, even in unopened cartons. Cartons should be removed from pallets and stringers to prevent distortion of material. Long-term (6-12 months) storage under uncontrolled environmental conditions should be avoided.
-
What is CAC?
CAC stands for Ceiling Attenuation Class. It is the measure of the blocking of sound through one ceiling plane, into the plenum above, and back through the other ceiling plane to an adjacent space.
-
Why would I use one ceiling panel type over another?
The different panel substrates provide panels with unique characteristics. The use of the different panels will vary based on specific needs and application.
