About this detail

An insulated pipe passes through a concrete or rated wall assembly with an annular space packed with mineral wool bat insulation and finished with sealant on both sides. The pipe features protective insulation and a jacket along its run through the penetration. Accompanying tables outline specific Underwriters Laboratories system designations, F ratings, and T ratings for single and multiple penetrants across concrete, concrete block, masonry, and gypsum board stud wall assemblies. General notes require verifying wall conditions prior to installation and installing firestopping strictly per manufacturer instructions.
