FP Response: The STC ratings have been revised to be accurate for a TJI assembly. Ref ERS-1153 pg 21 on sheet A-500A for the new compliance FP Response: The Fire Ratings are new referenced from the tested assembly ERS-1153 on sheet A-500G through A-500I. FP Response: The Fire Ratings now reference ERS-1153 with the addition of spray foam to meet R-Value compliance 08/14/18
