Did you know that insulating the walls of your home is just as important as roof insulation? That’s because uninsulated walls can lose as much as 20% of heat in winter and gain up to 25% more heat in summer. By protecting your home with appropriate wall insulation, you can stay comfortable throughout the year and save big on heating and cooling costs.
There are three main types of wall insulation you can choose from:
Batts are a form of bulk insulation usually made from materials such as glasswool, polyester or cellulose fibre. They provide thermal resistance through the countless air pockets trapped inside.
Batts can be a good insulation choice because they are:
- Designed to fit tightly into wall cavities, without leaving gaps that could lead to inefficiency
- Often made from recycled materials, making them a more environmentally friendly option
- Full of tiny air pockets that also provide some sound insulation
Rigid insulation is also a type of bulk insulation and comes in panels made from foam board.
Using rigid insulation has numerous advantages since it is:
- Strong and durable and can increase your home’s structural integrity
- Sometimes more effective than other insulation types due to higher R-values (its ability to resist heat transfer)
- Less likely to result in air leaks as it keeps its shape over time
- Made to fit into limited spaces where other insulation forms may not
- More sustainable if produced from post-consumer waste
Also known as flexible insulation, reflective insulation is usually made from aluminium, and looks like a metallic foil. It works by reflecting radiant heat, thereby reducing the amount of heat that comes into your home; and has low emissivity, which means it gives off much less heat than other materials.
There are several benefits of using reflective insulation to protect your home:
- Great insulation option for a hot climate like WA’s
- Acts as a good moisture barrier
- Reflects heat instead of absorbing it
- Low-cost and easy to install
No matter which type of wall insulation you pick, you’ll be making a sound decision that will continue to benefit you for many years to come.
