2. WHAT IS THERMAL INSULATION IN BUILDINGS ?
• Thermal insulation is process to
reduce the heat losses occurring
during winter mounts and heat gain
occurring during summer mounts.
• Thermal insulation is an important
technology to reduce energy
consumption in buildings by
preventing heat gain/loss through the
building envelope.
• Examples for thermal insulators:
Non-metals are good thermal insulator.
Other thermal insulators are Rubber,
tinfoil, wood, cloth, paper, Styrofoam
and plastic. loading.

3. THERMAL INSULATION IN MATERIALS
Most common thermal insulation materials :-
• Fiber glass
• Mineral Wool
• Cellulose
• Polyurethane foam
• Polystyrene

4. FIBRE GLASS
• The most common insulation used in modern
times.
• A reinforced plastic material composed of
glass fibers embedded in a resin matrix.
• Because of how it is made, by effectively
weaving fine strands of glass into an insulation
material, fiberglass is able to minimize heat
transfer.
• Fiberglass is an excellent non-flammable
insulation material
• If you are seeking a cheap insulation this is
definitely the way to go
• Installing it requires safety precautions.

5. Fiberglass reinforce panels provide a strong scratch resistant surface.
FRP could be cleaned easily using regular detergents, high pressure washers, or even by using
steam.
Fiberglass reinforced panel is a lightweight panel that is easy to install
FRP could be installed either with glue or fasteners
Maximum sanitation protection
Improved chemical resistance
FRP could be installed over any existing wall surface, by following some simple steps and no
high tech tools are required.
High impact resistance from shattering and scratches
Superior flexibility
FRP could save you money when preferred over other building materials
Fiberglass reinforced panels will allow the growth of mold or mildew and will not rust or corrod

7. • Mineral wool is a general name for fiber materials
that are formed
by spinning or drawing molten minerals (or "synthetic
minerals" such as slag and ceramics)
• Applications of mineral wool include thermal
insulation (as both structural insulation and pipe
insulation, though it is not as fire-resistant as high-
temperature insulation wool), filtration, soundproofing,
and hydroponic growth medium.
• Mineral wool is also known as mineral
fiber, mineral cotton, mineral fibre, man-made mineral
fibre, and man-made vitreous fiber.
• The nomenclature of these wool products is simply
the parent/raw material name in prefix to "wool".
Specific mineral wool products are stone wool and slag
wool. Europe also includes glass wool which, together
with ceramic fiber, are completely man-made fibers

9. CELLULOSE
• The word cellulose comes from the French
word cellule, for a living cell, and glucose, which is sugar.
• Building insulation is low-thermal-conductivity material
used to reduce building heat loss and gain, and reduce
noise transmission.
• Cellulose insulation is plant fiber used in wall and roof
cavities to insulate, draught proof and reduce free noise
• Cellulose insulation is often made by hammer
milling waste newspaper.
• The newspaper is treated with chemicals, such as boric
acid, to retard the spread of fire.
• Four major types of loose-fill cellulose products have
been developed under a variety of brand names. These are
generally characterized as dry cellulose, spray applied
cellulose, stabilized cellulose, and low dust cellulose.
These types are used in different parts of a building and for
different reasons

11. POLYURETHANE FOAM
• Polyurethane can be a solid or can have an
open cellular structure, in which case it is
called foam… and foams can be flexible or
rigid.
• As simple explanation, manufacturers
make polyurethane foam by reacting polyols
and diisocyanates, both products derived from
crude oil.
• One of the best commercially available
choices of insulation material for fishing
vessels is polyurethane foam.
• It has good thermal insulating properties, low
moisture-vapour permeability, high resistance
to water absorption, relatively high mechanical
strength and low density.
• Depending on the type of polyurethane,
different ways of recycling can be applied,
such as grinding and reuse or particle
bonding. Polyurethane foam, for example, is
regularly turned into carpet underlay. If it is
not recycled, the preferred option is energy
recovery

13. POLYSTYRENE
• Styrofoam is a good insulator because the
plastic foam contains billions of trapped gas
bubbles.
• Gases hinder heat conduction because their
molecules are very far apart making it difficult
for other molecules to collide with them.
• Insulation foam – are used for a variety of
applications because of its excellent set of
properties including good thermal insulation,
good damping properties and being extremely
light weight.
• From being used as building materials to
white foam packaging, expanded polystyrene
has a wide range of end use applications.
• foam is durable, strong as well as lightweight
and can be used as insulated panel systems for
facades, walls, roofs and floors in buildings, as
flotation material in the construction of marinas
and pontoons and as a lightweight fill in road
and railway construction.
