Understanding Insulation and R-Values
Proper insulation is one of the most effective ways to save energy at home. It keeps your house warm in the winter and cool in the summer by resisting the flow of heat. The performance of insulation is measured by its R-value—the higher the R-value, the greater the insulating effectiveness.
How to Use
- Select the area you want to insulate (Attic, Walls, Floor).
- Enter the dimensions (Length and Width) of the space.
- Choose the type of insulation you plan to use.
- Enter your current R-value (use 0 if the area is uninsulated).
- The target R-value will be auto-suggested, but you can adjust it.
- Review the real-time calculation results for required thickness, R-value, and costs.
