Reducing heat loss of any
building/System with an internal
temperature higher than the external
temperature will lose heat. Thermal
insulation reduces this heat loss, and
therefore helps to conserve energy and
reduce heating costs.
They are specialty products related to
the fire protective range and are made
primarily from mineral wool and cement,
or cellulose and adhesive.
They protect against thermal transfer in
specific applications such as on
concrete in basement car parks, or
excessive acoustic reverberation.
Thermal conductivity: This is a measure
of a material's ability to transmit
heat, and is expressed as heat flow in
watts per square meter of surface area
for a temperature gradient of one Kelvin
(K) per meter thickness. It is expressed
as W/mK.
Generally, dense materials have high
thermal conductivity and are inefficient
thermal insulants. Lightweight materials
have low conductivity and can be
efficient thermal insulants.
The lower the λ value of a material, the
better is its insulating efficiency.
Thermal resistance (R): This is the
measure of the resistance to the passage
of heat offered by the thickness of a
material and is expressed as m 2 K/W.
Thermal transmittance (U): The U value
of a building element is a property of
its whole construction, including air
spaces, and is a measure of its ability
to transmit heat under steady state
conditions. It is calculated by taking
the reciprocal of the sum of all the
individual thermal resistances and is
expressed as W/m 2 K. The lower the U
value of the element the better is its
thermal insulation.
For the purpose of calculating U values,
thermal resistances for the inside and
outside surfaces of a building element
and for any cavities within it also have
to be taken into account
