Insulation New Zealand – 3 Common Insulation Myths Debunked

insulation-free-assessmentThe New Zealand Building Code sets out a minimum standard of insulation for homes in New Zealand that are built after 2008.

This includes new homes as well as major extensions. It is important to note, though, that the standards are set at the minimum, not the optimum, level.

This means that, although your house may meet the standard for home insulation, it might not be as energy efficient as it could be. So, consider insulating to a maximum level for the most benefit.

Home Insulation Misconceptions

This is an example of one of the many misconceptions surrounding insulation and it is a reason why you should thoroughly research the subject before you organise insulation for your home.

Find out the truth behind some of the common myths about insulation.

Myth: Insulation in New Zealand Is Not Necessary in Areas with Warm Climate

Even warmer climates cool down over the winter months. The World Health Organisation recommends indoor temperatures should not drop below 18º and propose an optimal indoor temperature of 21º if babies or older people are in a house. Considering that New Zealand’s average indoor temperature in the winter is a mere 16º, insulation is necessary throughout the country, even in warmer northern areas.

Efficient insulation, even in warmer climates, will still reduce heating costs because heat loss is kept to a minimum. This means reduced energy bills over the winter. Over time, you will expect to save a significant amount of money.

Home Insulation Will Pay For Itself Over Summer

Insulation will also pay for itself over the summer months.  Heat flows naturally from a warmer to a cooler space. So, on hot days, warm air moves from the hot outdoors into the cooler exterior of your house, making it heat up quickly. Optimum levels of insulation prevent this heat exchange, keeping your home cooler during the summer months. This means you will rely less on energy guzzling air-conditioning systems or electric fans.

Myth: The R-Value Is the Sole Factor for Choosing Insulation New Zealand

The R-value measures how well insulation can resist heat flow. The higher the R-value, the more effective the insulation product is in slowing down the transfer of heat into, or out of, your home. R-values are important but they are not the only factor you should consider when looking at insulation for your home.

The insulation material should not emit any toxins or irritants, so check the chemicals used in its production and installation. All insulation products should also be fire-resistant. Durability is important, too. Does the product have a warranty? Is it resistant to pests and other vermin? Does it slump over time?

Keep in mind that the R-value is not the same for all insulation products made from the same material. It also depends on the type and thickness of the material. For instance, the R-value of blanket fibreglass insulation may be quite different to that of loose-fill insulation made from cellulose pellets.

Understanding R-values and comparing insulation products can be a tricky business. This is why it is important to contract a specialist company like Insulation NZ to help you.
