Spray foam takes home insulation to the next level by providing an air-tight seal. It expands upon application, filling even the smallest gaps and cracks. This insulation type is split into two categories: open-cell and closed-cell spray foam, with the latter being denser and offering higher R-values as well as moisture barrier properties. In the fluctuating climate of DFW, spray foam insulation can significantly reduce energy bills by maintaining indoor temperature levels more effectively.

  • Pros: Superior air sealing capabilities, excellent thermal resistance, and moisture barrier properties (closed-cell foam).
  • Cons: Higher initial cost, requires expert installation for optimal safety and performance.

Factors to Consider When Choosing Insulation Type

When selecting the correct type of insulation for your attic, consider factors such as the R-value, installation cost, effectiveness in different climates, and whether cellulose or fiberglass insulation would be more effective. The R-value indicates the insulation’s thermal resistance, with higher values providing better insulation. Wall insulation often has a significant R-value, contributing to a home’s energy efficiency.

Exploring Different R-Values for Insulation

R-value per inch varies for different types of insulation materials. For example, spray foam insulation typically has a higher R-value than fiberglass batts, making it a more efficient choice for insulation with limited space and ensuring that you insulate effectively.

What are the most common insulation materials used in DFW homes?

The most common materials used to insulate the attic are loose-fill insulation and rolls of insulation.
