In our situation, to <br />contain the grease duct above the TI t-bar ceiling within a one hour shaft we have basically two <br />options: <br />1. Extend the one hour shaft construction with gwb and framing or other approved shaft <br />construction until we are under the ceiling. <br />2. Wrap the duct with the "FireMater Duct Wrap" product as indicated in the sketch. <br />Please review the enclosed information nd call me to discuss our options at your earliest <br />convenience. <br />Thank you. <br />page 1 of 7 <br />
