Thermal Insulation

Purpose
To introduce resistance to prevailing thermal load, to either resist or to limit loss or gain, from one side of the medium to the other.

Design Function
In domestic and general buildings, during winter months, to limit heat loss through the ceiling and walls where the construction uses a thin membrane material such as plasterboard as a lining.
Its corresponding use as a thermal resistor to high heat loads during the summer months comes with a plus minus effect in that the greater the amount of insulation, the greater the absorption, therefore the longer the building will take to purge itself of the heatload during the evening cycle.

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.

If a manufacturer or promoter of any product, cannot tell you the relationship between their product and those that it will be used with, then they know little about what they are promoting or selling, or in telling you, would disadvantage their claims.

The reality is that there is no advantage without a corresponding disadvantage and anyone advising differently should be questioned as to rationale.

Bigger or Greater is not Better!

In most conditions, the use of an insulative medium above r2.5 is not warranted and even then should be used in a manner so saturation does not occur, and any high heat load absorbed can be dissipated quickly and efficiently.

A decision should never be made until full awareness has been realized.

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 Condition have totally separate areas of function and the use of one does not replace, or is a substitute for, the other.

In simple terms:

Insulation - is like putting an on overcoat to prevent heat loss
Ventilation - is like breathing
Air Conditioning -cooling -a cost based climate system controlling living conditions based consumption of electrical energy with, or without, water.

Putting on an overcoat is not going to make you breathe any better,
and turning on the air conditioner is not going to improve the quality of air.

Conversely, breathing well is not going to make you any warmer, will contribute to your remaining cooler, but is guaranteed to keeping you healthier.

As with anything, being well informed always produces the best decisions

Use the right product for the right reasons by Isa Stralian

Unfortunately home owners in Australia, particulary Queensland, the Territory and upper half of West Australia, who made a rush for free insulation, believing the federal goverments' mantra, will now have decidedly warmer homes in all seasons, and especially during summer months.

This also means those with airconditioners in the whole of Australia will have them on longer during the Summer months and what was supposed to be an advantage is now a decidedly disasterous disadvantage. So much for the carbon footprint we're all supposed to be concerned about.

A little like acquiring the Plague because it's free and justifying it because it's guaranteed to help you lose weight.
