Drywall is a common and most
popular finishing material. It is
versatile in use: it is used to align
walls, create various structures
(multi-level ceilings, arches, niches).
Drywall it is a perfectly flat sheet
consisting of a core and two layers
of special cardboard. The first
component contains gypsum dough
of a solid consistency and various
fillers. Among the components of
drywall are also adhesives and
foaming agents for gypsum.

Drywall appeared between 1910 and 1930,
starting with the wrapped edges of cardboard
and the abandonment of two inner layers of felt
paper in favor of paper-based cladding. In 1910,
the United States Gypsum Corporation bought
the Sackett Plastic Board Company and
introduced drywall by 1917. Ensuring the
efficiency of the installation, it was additionally
developed as an indicator of fire resistance.
