                     TYPES OF WALL SURFACES
Learning Objectives:
After reading this INFORMATION SHEET, YOU MUST be able to:
          1. Identify the different types wall surfaces
What Are Walls?
A wall is a structure and a surface that defines an area, carries a load,
provides security, shelter, or soundproofing, or, is decorative.
There are many kinds of walls, including Walls in buildings that form
a fundamental part of the superstructure or separate interior rooms,
sometimes for fire safety.
What Is the Purpose of Wall?
    Wall is a structure that defines the area.
    It defines the boundaries of an area.
    It carries the load of the roof slab.
    It provides security and privacy.
    It is used as a soundproof material.
    It’s one of the most important superstructures in buildings
Interior walls consist of both load-bearing  walls and walls that don’t
bear weight, called partition walls.
Both types of  walls employ similar framing standards, but a load-
bearing wall is typically located directly above another load-
bearing wall, a beam or a structural column.
    Interior wall provides safety, security, and privacy.
    It creates a partition and transforms a large room into two small
     rooms.
    Interior walls are nicely decorated, which gives the aesthetic
     beauty of that room.
    It’s used as the platform for hanging materials, pictures, or other
     decorative materials.
Types of Interior Wall Materials
There are different types of materials are used to construct a wall.
Some of them are-
    Brick Wall
    Stone Wall
    Glass Wall
    Wood Wall
    Plywood Wall
    Cinder Blocks Wall
    Metal Sheet Wall
1. Brick Wall-
The brick is mainly used as wall material because it’s very easy to use and
economical. A contemporary brick wall is typically made of clay, concrete, or
                               calcium-silicate bricks. The most common brick 
                               size is 215mm (L) x 102 .5mm (W) x 65mm
                               (H). Bricks are bound together by a cementitious
                               or lime mortar, usually 10mm thick for the
                               horizontal (bedding) joints and 10mm wide for the
                               vertical (perpend) joints.
                                #2. Stone Wall-
                            In ancient times stone is used as a wall
                            material. Stone walls are usually made of
local materials varying from limestone and flint to granite and
sandstone. However, the quality of building stone varies greatly, both
in      its      endurance
to weathering, resistance                               to       water
penetration and in its                                  ability to be
worked      into    regular                             shapes
before construction.
3. Glass Wall-
Now a day glass is very                                useful
material. Architectural                                glass  is used
as a building material. It                             is        most
typically used as transparent glazing material in the building
                          envelope,     including windows in      the
                          external walls.
                              4. Wooden Wall
                              Hardwoods are      commonly      used  in
                              the construction of walls,  ceilings  and
                              floors, while softwoods are often used to
make doors, furniture, and window frames. Some examples of the
most popular hardwoods include oak, maple, mahogany, cherry,
walnut, and teak. Wood is used as a wall material, and it’s quite a bit
expensive, but the durability & longevity of wood is extremely good.
5. Plywood Wall
It is not as durable or easy to work with as drywall. These thin sheets
of wood are bonded together with an adhesive. Plywood is not visually
appealing which is another one of its drawbacks as a wall material,
however, it can still be used as one. It’s used in Interior wall
materials.
                            6. Cinder Blocks Wall
                            It’s used to the soundproof barrier, and it’s
                            economical. Concrete      blocks are        a
                            prefabricated material mainly used to build
                            walls.Like bricks, the blocks are stacked
                            together and joined with a mortar, usually
                            consisting of cement, sand, and water. The
blocks are hollow inside to allow for steel  bars and mortar filling.
7. Metal Sheet Wall
It’s quite expensive but                          the durability of this
type     of    Sheet    is                        high. Steel      has a
notable          immense                          strength that offers a
great advantage         to                        houses. Another vital
feature of sheets is in                           its flexibility.Yes, it
bends     easily   without                        cracking       even  if
subjected to an external force. They come in a wide range of finishes
and gauges so fashioning its walls is easy.It has been the
ideal material for along time in industrial buildings but lately, it is
                         also a popular choice for many contemporary
                         and modern houses. The series of significant
                         advantages against the other materials makes
                         projects look more exciting and exceptional.
