Understand how insulation is like an esky, creating a thermal barrier between your home and the outside to keep you comfortable and energy efficient all year.
Insulation is not complicated in fact, it's very simple, kind of like an esky. We all know that an esky will keep your food cold or warm regardless of the temperature outside the esky. It works by creating a thermal barrier between the internal temperature and the external temperature. In your home, insulation does the same thing, and it can help you save money all year round.
The basic physics behind insulation
Heat will shift from higher to lower temperatures until the temperature is the same in both areas the same as heat will leave your coffee on a cold day, or enter your fridge if you leave the door open. In summer, if you've got your air-conditioning running, the outside heat will try to get in where it's cooler. In winter, when you've got your house heated, the heat will try to get out into the cold.
Insulation's job is to slow down this heat transfer and it does this by trapping the heat in the air pockets between the thin fibres of glasswool. The more insulation you have and the more places you have it, the cheaper it will be to keep your comfortable all year round.
