ALINSULATION?
Thermal Insulation is the reduction of heat transfer between objects in
thermal contract or in range of radiative influence.
In simple thermal insulation of buildings mean in hotter area keep the room
cold and in colder area keep it hot.
Also we can say thermal insulation of buildings means creating a shield
around your home to maintain your rooms temperature according to your
requirement.

ESSARY?
Thermal Insulation is necessary for every one who are constructing buildings.
In todays world Global warming is increasing day by day, for which whether is
changing Drastically.
Due to weather change the world is getting temperature variation, some where it
is very cold, and some other area it is very hot.
And get rid of extreme weather conditions man has invented every possible
devices to tackle this problem.
Such as A/C, room heater etc.
But these equipment's will have another issue that is electricity problem. You have
to pay huge amount of money for bills and the gases releasing from this device
have very bad impact on the environment.
So it is better to have make thermally insulated home rather than paying heavy
amount of electric bills.

Y INSULATED?
To make your house thermally insulated you can do
in the following way.
First while choosing materials for building
construction choose the material which are
thermally insulated. In that way halif of your work
will be done.
Second is you have to add materials for your home
which can make your house property thermally
insulated.

There are many materials which are thermally insulated
o Doors and Windows:- These are various materials available
which can help to maintain room temperature. Such as fibber
door, upvc door, pvc door and window, wooden door and
window. It seems like doors and windows have no importance
in insulation process, but they affect mainly as the air to room
passes through them. Even if a small gap can make large
impact in temperature.
o Colour and surface:- Light coloured and smooth materials have
higher reflectivity than dark coloured and rough materials.
Whitewash, white paints, Marble have high reflectivity
coefficient.

ATERIALS:-
There are 4 types of thermal insulation materials-
1. FIBERGLASS:-Fiberglass insulating material made up of
fine glass fibbers. It is mostly found in many homes. These
fibber glass insulating material come in 2 types-[a] Roll or Batts
[b] Rigid boards.
ADVANTAGES- It can be easily moulded into any shape and has
mechanical strength that is strong and stiff. It lasts for long time.
No maintenance required. Its is anti-magnetic, fire resistant, good
electrical insulator, fire proof.
DISADVANTAGES- It needs to be re-gel coated every 5 years. It
may not work if it is wet or damp during installation.

ATERIALS:-
2.MINERALWOOL:-Mineral wool is a fibrous material drawn
from molten mineral or rock mineral
ADVANTAGES- It is installed as sheet into walls.
It is fire resistant, noise resistant.
DISADVANTAGES- It is very expensive material.
3.CELLULOSE:- Cellulose insulation is plant fibber used in wall
and roof cavities to insulate, draught proof and reduce free noise.
ADVANTAGES- It is treated with boric acid which makes them fire
resistant and makes them unpalatable. Have long term thermal
insulating properties. Cheaper than fiberglass. Health risk is less.
DISADVANTAGES- Creates enormous amount of dust when
installed.

4. POL
YURETHANE FOAM
:-
 Polyurethane foam insulation is made up of two chemicals.
These foam insulation are spread on walls and roofs and then
it solidifies to make an insulating material.
 There are 2 types of foam material [a] Open cell spray foam.
[b] Closed cell spray foam.
 Reduces HVAC capacity requirements.
 Have stable insulation over time.
 Reduces air and moisture Infiltration resulting in a more
consistent temperature.

OCHOOSEINSULA
TINGMATERIAL:-
 During choosing thermal insulation material choose that which have better
thermal insulation .
 And most important thing is whether the materials insulation capacity is long
lasting or not.
 Next how much will it cost.
 How much will it take to install them.
 If it requires maintenance or not.
