How does insulation work?
Insulation prevents heat loss by slowing down heat loss in winter and heat gains in summer in one (or both) of two ways:
• Bulk Insulation (thick layers of dense materials that trap heat inside or outside your home)
• Foil Insulation (reflective layers that bounce heat back)
Both methods slow down your home’s transfer of heat so that you don’t have to use heaters or air conditioners as much (and when you do, you don’t need to run them as long) to maintain a comfortable indoor temperature. In this way, insulation acts as a blanket for your home.
Does wall insulation affect electrical work?
Yes, it can. There are different levels of power allowed through your electrical cables depending on the type of insulation that surrounds them. The reason for this is a cable that is surrounded by insulation can’t dissipate as much heat as a cable ...
Should insulation be compressed?
No. When you compress insulation, the overall R-value goes down because you have less thickness of insulation. So, you don't get the full R-value on the label but the insulation will work to a certain extent if you compress it.
How much insulation do I need?
This will depend on which climate zone you live in. In each climate zone, the Building Code of Australia has determined a minimum amount of needed insulation expressed in R-value (the efficiency of a material at stopping heat flow through it.) This ...
What is sarking and how does it relate to insulation?
Sarking is a pliable membrane that sits under your roofing, like a protective second skin. It helps insulation work more efficiently and protects the things you value from storm driven rain and dust, condensation and bush fire ember attack. It helps ...
Is insulation safe?
