11.2 Separate Cushion Selection
It is required that the cushion conform to carpet manufacturer recommendations
for the specific product being installed. Failure to follow these recommendations
for cushion may void manufacturer warranties. These recommendations may
differ, depending on the style and construction of specific carpet. Cushion
thickness for Residential carpet installations should not exceed 7/16
inch (11 mm).
Install separate carpet cushion in the longest continuous lengths possible, with
cushion seams placed at right angles to carpet seams, or offset at least 6 inches (150
mm) to one side. Trim cushion flush with the inside contour of the tack strip and
securely fasten to the substrate using staples or nonflammable cushion adhesive at
all seams and around the perimeter of each room. With the exception of fiber
cushions, secure seams with appropriate vinyl-coated cloth cushion tape per the
carpet cushion manufacturer’s recommendations.

The seaming method depends upon carpet construction and backing type. Refer to
Section 10.3.
