There are many different types of insulation on the market, but the most important factor to consider when choosing insulation for your home or business is its R Value.

The R Value is a measure of a material's resistance to heat flow (known as thermal resistance).

The higher the R Value, the greater the resistance to heat transfer, the greater the insulating effect and the greater the energy savings. Different products with the same R Value will provide similar insulation performance. Remember, it's not necessarily the thickness of the product or the type of material that counts, but the R Value.

R Values for Victorian Homes

Recommended R values for Victoria are shown below.

                 Minimum  Recommended

Ceiling        R3.5              R5

Walls           R1.5            R2.5

Floors          R1                 R2

Tips

  • It's important not to insulation batts when installing. If it's compressed, the air pockets are reduced and the material will lose its insulating properties.
  • When installing it's important to leave no gaps between batts. Any gaps will allow heat transfer and reduce performance.
  • Installing insulation carries potential risks and requires expert knowledge. Contact us for further information or to discuss your insulation needs.
