3.2 GRACE ICE AND WATER SHIELD DAMPING MATERIAL
An alternate (lower cost) pipe damping material referred to as "Grace Ice and Water
Shield" can be considered for use with 1010 Clamp-On Gas systems. This opaque mate-
rial has a black tar like appearance with a very tenacious adhesive backing. Its lower
operating temperature range and difficult removal from the pipe must be considered
before installing this alternate material. Refer to the web site (www.graceconstruction.com)
for a local distributors of this roofing underlayment material.
The installation and sizing of the Grace material is identical to that of CC129-1A. Refer
to Table 2 below for the recommended number in layers for each transducer size. (Oper-
ating / Installation temperature ranges can be found just below Table 2.)
