The special wall shield design described in Figure 20 is an alternate method of adding protection to side walls and can be used in place of the SP40 with the same wall clearances specified for the SP40. Rt must =1.85 minimum.
Examples of wall shield insulation:
1.Manville - CERAFORM 126, K=.27, 1/2 inches thick
2.CFM Corporation - EH2416, K = .458, 1 inch thick required.
