Selection Guidance

1. Consider Application Area

  • Above Grade: Fiberglass Batts or Polyiso can be suitable.
  • Below Grade: Opt for moisture-resistant products like XPS insulation boards.

2. Assess Required R-value

  • Higher R-value products offer better thermal resistance. Determine the needed R-value based on local building codes and climate.

3. Evaluate Installation Ease

  • Choose products that align with your installation capabilities—some products, like fiberglass batts, are more user-friendly and suitable for DIY projects.

4. Budget Constraints

  • Establish a budget and select a product that offers the best value for the cost. While higher R-value products might be more expensive, they can offer better long-term value.
