R7 vs. R8 Insulation: Which is Right for Your Home?

When it comes to insulating your home, the R-value is one of the most important factors to consider. High R-value insulation like R7 and R8 provides exceptional thermal resistance, making it ideal for extreme climates. But which one is the better choice for your home? In this guide, we’ll compare R7 and R8 insulation, exploring their benefits, costs, and applications to help you make an informed decision.

What is R-Value and Why Does It Matter?

The R-value measures an insulation material’s ability to resist heat flow. The higher the R-value, the more effective the insulation is at maintaining indoor temperatures. Both R7 and R8 insulation fall into the high-performance category, offering superior thermal resistance for roofs and ceilings, particularly in hot or cold climates like those in Perth and WA.
