Insulation
Realities
The
purpose of which is
to limit heat loss or gain.
In domestic
and general buildings, during winter months, to limit heat loss
through the ceiling and walls where the manner of construction
consists of a thin membrane material such as plasterboard as
a lining.
Its corresponding
performance during the summer months comes with a plus minus
effect, in that the greater the amount of insulation, the greater
the storage potential, therefore the longer the building will
take to purge itself of the heat load during the evening cycle.
The house
is less resistant to ambient change
Various
entities including govt. based organisations will attempt to
suggest that insulation will provide all the necessary comfort
levels desirable but disappear into the wilderness when asked
to show their rationale, or attempt to change the narrative.
The reality
is that there is no advantage without a corresponding disadvantage
and anyone advising differently should be questioned as to rationale.
Bigger
is not always Better!
In most
conditions, the use of an insulative medium above r3.0 is not
warranted and even then should be used in a manner so saturation
is avoided, and in the roof space appropriate venting should
be employed with any high heat load absorbed being dissipated
quickly and efficiently.
A decision
should never be made until full awareness has been acquired.
Unfortunately
there are those that think that when a word ends in ion, one
is a substitute for the other.
A dangerous presumption!
Insulation,
Ventilation, Air conditioning have totally separate areas of
function and one does not replace, and or, is a substitute for,
the other. Just as do the tyres, steering wheel and brakes in
a car.
In
simple terms:
Insulation
is like putting an on overcoat, to prevent heat loss or gain
Ventilation
is like breathing
Air Conditioning
-cooling -a cost based climate system controlling living conditions
reliant on consumption of electrical energy with or without
water.
Putting
on an overcoat is not going to make you breathe any better,
and the air conditioner is not going to improve the quality
of air.
Conversely,
breathing well is not going to make you any warmer, but it will
contribute to your remaining cooler, and is guaranteed to keeping
you healthier.
Use the
right product for the right reasons and avoid trying to demean
the validity of the product, or approach, on the basis of financial
outlay because in the end you are the one that is ultimately
going to wear the outcome
As with
anything, a solution based on comprehensive understanding always
produces the best outcomes.
