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 material 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. (Operating / Installation
temperature ranges can be found just below Table 2.)
