2. INTRODUCTION
ANNEX GLOBAL started in 2015 primarily as a SOLAR Consultant and Impex company importing
wide range of construction related products. We have expanded ourselves into Trading of
products like PVC False Ceilings, Gypsum Boards, EPS Sandwich Panels, XPS Sandwich Panels, Mgo
Boards, Readymade Main Doors, Bedroom Doors, Bathroom Doors apart and other building
related materials, which are the future generation products providing long lasting solutions.
We got associated with our overseas partners for developing custom-made PVC False Ceilings and
readymade doors. Based on high priority for quality, fair and ethical business practices, use of
modern technology and with our rich experience in construction industry, name has become
synonymous for Quality.
Introduction to Gypsum Boards: Gypsum board is the generic name for a family of panel products
that consist of a noncombustible core, composed primarily
Of gypsum, and a paper surfacing on the face, back and long edges. Gypsum board is one of several
building materials covered by the umbrella term “gypsum panel products.” All gypsum panel
products contain gypsum cores; however, they can be faced with a variety of different materials,
including paper and fiberglass mats.
Gypsum board is often called drywall, wallboard, or plasterboard. It differs from other panel-type
building products, such as plywood, hardboard, and fiberboard, because of its noncombustible core
and paper facers. When joints and fastener heads are covered with a joint compound system, gypsum
wall board creates a continuous surface suitable for most types of interior decoration.

3. Advantages of Gypsum Board Construction
Gypsum board walls and ceilings have a number of outstanding advantages:
>Ease of installation
>Fire resistance
>Sound isolation
>Durability
>Economy
>Versatility
Ease of installation: Gypsum board building systems are easy to install for several reasons. Gypsum
board panels are relatively large compared to other materials.. Gypsum board assemblies require
only a few tools for their construction. Gypsum board can be cut with either a utility knife or a
variety of saws, and it can be attached with a variety of fasteners, including screws, nails, and
staples. It can also be adhesively attached to many substrates. Gypsum board is a lightweight
material. Two workers can easily handle most panels and cover large areas in very short time
periods. Gypsum board is easily finished using either a few hand tools or relatively modest
machines. Gypsum board installers can quickly learn most application techniques in a few hours.

4. Fire resistance: Gypsum board is an excellent fire-resistive building material. In North America, it is
the most commonly used interior finish where fire resistance classifications are required. Its
noncombustible core contains nearly 21% chemically combined water, as described earlier, which,
under high heat, is slowly released as steam. Because steam will not exceed 212 degrees F under
normal atmospheric pressure, it very effectively retards the transfer of heat and the spread of fire.
Even after complete calcination, when all the water has been released from its core, gypsum board
continues to serve as a heat-insulating barrier. Moreover, tests conducted in accordance with ASTM
E 84 show that gypsum board has a low flame-spread index and a low smoke-density index. When
installed in combination with other materials in laboratory-tested wall and ceiling assemblies,
gypsum board serves to effectively protect building elements from fire for prescribed time periods.
Sound isolation: Preventing the transfer of unwanted sound to adjoining areas is a key
consideration when designing a building, specifically when taking into account the intended
activities of the occupants in the various parts of the building. For example, a building containing
office spaces adjacent to manufacturing facilities requires more noise-reducing features than are
typically necessary in a building that has only office space in it. Gypsum board wall and ceilings
systems effectively help control sound transmission.
Durability: Gypsum board is used to construct strong, high quality walls and ceilings that offer
excellent dimensional stability and durability. Surfaces created using gypsum board are easily
decorated and refinished.

5. Economy: Gypsum board is readily available and easy to apply. It is an inexpensive wall surfacing
material that provides a fire resistant interior finish. Gypsum board building systems can generally
be installed at significantly lower labor costs than most alternate systems.
Versatility: Gypsum board satisfies a wide range of architectural requirements for design. Ease of
application, performance, ease of repair, availability, and its adaptability to all forms of decoration
combine to make gypsum board unmatched by any other surfacing product.
