With the continued popularity of high-rise corporate headquarters,
institutional buildings and high-density housing, the gypsum shaftwall
system, known as the Cavity Shaftwall System, provides economic benefits
– and also peace of mind due to its fire-resistant qualities.
Originally designed for the 110-story World Trade Center in 1973, the
Cavity Shaftwall System replaced heavier, more expensive masonry walls.
This shaftwall system utilizes gypsum board framed with metal studs and
tracks to enclose elevator shafts, stairwells and service shafts. These
shaftwalls withstand the positive and negative air pressure forces
exerted by high-speed elevators. Cavity Shaftwall Systems are also ideal
for fire-rated, interior partitions where access is restricted to one
side and as fire-rated, horizontal membranes.
