Thermal Insulation reduces the flow of heat through structures
of the building such as walls, ceilings, roofs and
floors. By adding bulk insulation, the temperature can be adjusted.
Today, when discussing insulation, the first thought that most will
have is the use of an insulation material in a thermal application.
Man has been using materials - both knowingly and unknowingly - for
thousands of years to keep his living environment comfortable for
himself and his family. Insulation is normally associated with the
positioning of a material – normally a fibrous mat or wadding -
which acts as a barrier to the movement of heat through the
bulk.
When designing dwellings or structures all facets of the
building must be taken into account:
The orientation of the building will markedly effect the
requirements the structure has in relation to the insulation. The
presence or absence of shading or overhang etc will have an effect
on the level of heat transfer across walls and through the ceiling.
Large windows, especially on the northern and western sides of a
building, can negate the effects of insulated walls and ceilings.
The materials from which the building walls are constructed will
affect the rate of heat transfer and thus the level of insulation
that is required.
The relative levels of external and internal temperatures will
affect the rating of insulation required. Apart from the above, the
major entry points for heat into a building are through the ceiling
and walls. The installation of the correct rated
level of insulation (see AS2627.1) to the ceiling/roof and the
external walls can markedly improve the liveability and comfort
levels of a building. In this way, the entry or exit of heat
through the walls, roof, or floor of a building can be
significantly reduced, thereby making the inhabitants more
comfortable and saving heating or cooling costs in the process.
When it comes to the best types of
insulation for your building project, health and our
environment we recommend either Natural Wool or Regenerated
Polyester Insulation for thermal applications.
