Paint vs. Vinyl Siding + Foam Insulation Board – Money & Energy Costs
Energy Savings Table
The following table illustrates that 1/2 inch foam insulating board can definitely save you money. In fact, it can go a long way in helping to pay for the initial cost of the vinyl siding installation. This table shows the benefits after 20 years, a reasonable life expectancy for a vinyl siding job. In other words, if you are going to install vinyl, there is a good chance it will remain on your house for at least 20 years. The heating costs have been adjusted for inflation (the adjustment is minimal and not realistic - the values have been adjusted just 1 percent per year). Actual annual inflation has been higher than 1 percent. Thus, your savings would be greater than those shown in the table if inflation is greater than 1 percent per year.
All figures are in dollar ($) values.
