Acoustical cladding

Acoustical cladding material should be used around all piping and ductwork which
passes through noise-sensitive areas within buildings. While it is recommended
that, for most applications, the wrapping should be continuous over the length of
the pipe or duct, it is appreciated that there are some instances where this
represents a large amount of material. Partial wrapping may be acceptable for
some non-critical applications. It is recommended that cladding be used a
minimum of 10 pipe diameters upstream and 20 diameters downstream of all
transitions, tees, valves, branch takeoffs or similar to ensure laminar flow beyond
the cladding.
