Pittsburgh CorningProVantage Glass Block Installation SystemAssembly Instructions

Introduction:The ProVantage Glass Block Installation System isthe easiest way to install Pittsburgh Corning PremiereSeries (4" thick) Glass Block, and get professionalresults. There are two methods of installation -ProVantage I and ProVantage II. Here is additionalinformation about each method.

ProVantage I: (page 3) This method is used to install straight walls in

4-sided openings. In this method, glass block panels are installed in

perimeter channel. The maximum opening size for exterior panels is

50 square feet. The maximum opening size for interior panels is

85 square feet. 7KH MRLQWV RI WKHVH SDQHOV FDQ EH QLVKHG ZLWKProVantage Glass Block Surface Grout orPittsburgh Corning Glass Block Sealant. SealantQLVKLQJ LV QRW UHFRPPHQGHG IRU ZHW HQYLURQPHQWV
