R-Value

What is the R-value?

The R-Value of insulation is a measure of how well a two-dimensional barrier, such as a layer of insulation, resists the conductive flow of heat. The higher the R-value the higher the thermal resistance. For homeowners and DIY renovators, it is important to understand what effect the R-value has on your home. In order to find the best insulation for your home, we'd suggest the highest R-value you can afford. This means you'll receive more savings on your power bill due to its effectiveness. However, we can suggest some R-values for specific jobs. Perth Insulation Centre stocks Earthwool, which carry the standard R-values.

What is HD Insulation?

The HD (or high density) insulation is recommended due to its noise reduction characteristics. It'll create a more enjoyable living space that doesn't facilitate the noise transfer between rooms.
