Insulation Has the Best R-value

Whether you’re building a new home or retrofitting an existing one, insulation in Victoria is an important consideration. Insulation helps to keep your home warm in winter and cool in summer, and can also help to reduce your energy bills.

There are a few different things to consider when choosing insulation, including the type of insulation, the R-value, and the thickness.

The type of insulation you choose will depend on a number of factors, including the climate you live in, the type of home you have, and your budget. Some common types of insulation include fiberglass, batt and poly, and spray foam.


The R-value is a measure of an insulation’s ability to resist heat flow. The higher the R-value, the better the insulation. The R-value of insulation varies depending on the type and thickness of the insulation.

The thickness of insulation also varies depending on the type of insulation and the R-value you’re looking for. For example, fiberglass insulation is available in a range of thicknesses, from 3 inches to 12 inches.

When choosing insulation, it’s important to consider both the R-value and the thickness to ensure you’re getting the best possible performance. Insulation is an important consideration for any home, so make sure you take the time to choose the right option for your needs.


Closed cell spray foam is considered to have the best R-value of any insulation type, with an R-value of around 6.5 per inch. This means that it’s able to resist heat flow better than other types of insulation, making it a great choice for both new construction and retrofit projects.

Fiberglass is another good option for insulation, with an R-value of around 3.1-3.4 per inch. It’s important to note that the R-value of fiberglass can vary depending on the density of the material. Higher density fiberglass will have a higher R-value than lower density fiberglass.

Batt and poly insulation are also good choices for insulation, with R-values around 3-4 per inch.

No matter what type of insulation you choose, make sure you select the right R-value for your climate and needs. Insulation is an important part of any home, so make sure you take the time to choose the best option for your situation. We can help! Contact us today.
