False Ceiling Materials

MATERIAS
GYPSUM BOARD POP
PVC GLASS
WOOD ACOUSTICAL

GYPSUM BOARD
 Gypsum items possess the following important Properties
1.They are in combustible.
2.They possess relatively small bulk density.
3.They serve as good sound absorbers
 The main reason for gypsum board being a popular material for
false ceiling are
a) Ease of Installation
b) Fire Resistance
c) Sound Insulation
d) Durability, Economy & Versatility
 It is a Panel made of gypsum plaster.
 It is pressed between two sheets of paper.
 It is used to make interior walls and ceilings.
Sizes of Gypsum Board
 4’x4’
 6’x6’
 6’x4’
Thickness of Gypsum Board
 8mm
 10mm(mostly use for large ceiling)
 12mm
 Upto 20mm

PLASTER OF PARIS (P.O.P)
Advantages
 A smooth, uniform finish.
 The surface can be recovered or painted.
 Easy to construct and maintain.
 The ceiling are really light.
Facts about POP
 Plaster of Paris is a type of ceiling that originally originated
from France
 It is a mixture of calcined gypsum, sand & water.
 When these ingredients are mixed together and the
subsequent paste is allowed to dry, it hardens and forms a
tough coating.
Installation
 Fixing the framework directly on the beam and structural
ceiling.
 Fixing the wall supports and angles supports
 Fixing the suspended framework on the supporting members.
 Fixing of POP boards.
 Applying insulation.
 Finishing the joints.
 Edging profile.
 Fixing the moldings and decorative motifs.
 Final finishing with paints for desired effects.

GLASS
 Usual transparent glass is never used, as it contradicts the very
idea of false ceiling-to hide from the viewer’s eye and defects
and irregularities and other services wiring , plumbing, air
conditioning systems etc
 Frosted glass is mostly used other than back painted, stained
glass, mirrors etc
Advantages
 Creates the illusion of depth, it makes the room visually higher.
 Resist moisture and temperature fluctuations.
 Easy to clean and maintain.
 Suspended glass ceiling with stained glass panels can be
decorated with the image or using the in jet printing on
special equipment, or a sticker on top of the glass transparent
film with a pattern.
Disadvantages
 Hard and brittle to cut, drill and work with.
 Suspended glass ceiling are quite heavy compared to other
materials.
 Most dangerous if any glass tile breaks during repair works.
 Not advisable in earthquake prone areas.

WOOD
Advantages
 Very economical.
 Natural acoustical properties.
 Esthetic appeal gives richness to the space.
 Effective for creating rustic look.
 Give warmth to the space.
Disadvantages
 Comparatively heavier than other materials.
 Lessens the visual height of the room.
 Cannot withstand attack of pest like termites for long period.
 Not recommended for damp spaces or leakage prone areas.
Basic Materials
 The material used in false ceiling is made up of either hard or
MDF or particle board.
 In MDF mica is used to glue the either sides of the board.
 Using solid wood is not recommended because it is heavy.
 The one on the inner side of the board is known as “Balanced
surface”
 The one on the external side i.e. the visible surface is known as
the “finished surface”.
 Where as the wood gives the natural finish when polished.
Installation
 Grid system is formed with the help of wooden joists.
 Modular grid size 400x600mm
 Grid system is supported by hanger wire & wooden screws.
 Each cell is filled with lightweight “wooden panels”.

ACOUSTIC BOARD
 Board made of sound absorbing materials.
 Its job is to provide sound insulation.
 Ceiling is porous.
 When sound passes through an acoustic board the intensity of sound is
decreased.
 The loss of sound energy is balanced by producing heat energy.
 Used in auditoriums, halls, seminar rooms, libraries etc.
