Comparative Cost Analysis: Fiberglass vs. Foam Insulation Homes

Let’s delve into a detailed cost comparison between homes with fiberglass insulation and those with foam insulation, taking into account both the mortgage and average heating/cooling costs.

Fiberglass Insulation Home:

• Mortgage Details: $300,000 over 30 years at a 6% interest rate.
• Monthly Principal and Interest (P/I): $1,798.55.
• Average Heating/Cooling Costs: $300.00 per month.
• Total Monthly Payments: $2,098.55.

Foam Insulation Home:

• Mortgage Details: $308,000 over 30 years at a 6% interest rate (accounting for the slightly higher initial investment in foam insulation).
• Monthly Principal and Interest (P/I): $1,846.63.
• Average Heating/Cooling Costs: $225.00 per month (This reflects a 25% reduction. However, actual savings could reach up to 50%, enhancing the financial benefits).
• Total Monthly Payments: $2,071.63.

Key Takeaway: While the foam insulation home has a marginally higher mortgage due to its increased initial cost, the savings in heating/cooling expenses bring its total monthly payments below that of the fiberglass insulation home. This example demonstrates the long-term cost-effectiveness of foam insulation in reducing utility expenses, potentially leading to significant savings over the life of the mortgage.
