Why Do We Need To Insulate Our Buildings?
4
Insulating your house helps to maintain a
comfortable living environment by maintaining
inside temperatures and reducing energy costs.
5
The main purpose of insulation is to create a
barrier around the building, that is, over the
roof, on the wall, and beneath the floor,
6
which reduces the amount of heat entering the
home on a warm day, and reducing the amount of
heat loss on a cold day.
7
Since the majority if heat is lost or gained
through the roof and the exposed walls, these
areas are the most fundamental places to insulate
in order to create a comfortable and energy
efficient home.

How does insulation work?
9
On a hot day, like most typical Maltese days
during the period from May till September, a
concrete roof and walls exposed to the sun
without insulation will start to absorb heat from
outside the building. The roof will become hotter
and hotter, and will start to emit this heat in
the building, which will result hotter
environment within the building.
10
Due to the concrete and bricks' heat capacity,
the roof and walls remain warm during the night,
and the inside of the building becomes
uncomfortably hot during summers.
11
The opposite happens during winter, in which the
heat from the house is absorbed by the roof and
walls, and emitted outside. During night-time the
inside temperature can easily match the chilling
outside temperature.
12
Heat always travels from the hotter area towards
the colder area. The only way to stop this
process is through good insulation. In a house
with insulation, heat flow through the ceiling
and walls is vastly limited, depending on the
thermal conductivity of the material installed.
13
Good insulation will prevent heat from travelling
through the roof and walls, thus the building
temperature can be kept comfortable with much
less heating and cooling energy. 
14
Therefore the inside of the building remains
relatively cooler than the hotter outside
environment, and on a cold night or during
winter, the majority of heat that is inside the
house will remain trapped by the insulation
barrier, thus keeping the building warm.
