About this detail

An isolated pipe penetration passes through partition, ceiling, roof, or floor construction centered within a twenty-five gauge minimum metal sleeve. The pipe is insulated with fiberglass insulation at a maximum of one point five pounds per cubic foot at one hundred percent fill, and sealed with resilient caulking at the sleeve ends. The pipe remains unattached to the structure without mechanical ties or wedges, maintaining the required annular space and clearance for positional movement.
