Why the most expensive insulation isn't always the best choice
In short: Choosing between fiberglass and spray foam isn't just about price tags; it's about understanding how different materials manage heat and air. This video breaks down the mechanics of both options to help you determine which actually fits your specific building needs.
The video explores the fundamental differences between nearly century-old fiberglass technology and modern spray-applied foams. While both materials aim to control heat transfer, they function differently: fiberglass acts as a traditional insulator, whereas spray foam can also serve as a critical air barrier.
Key distinctions include the differences between open-cell and closed-cell foams, their respective R-values, moisture resistance, and installation requirements. The core takeaway is that the superior choice depends on the specific building, the available space, and the quality of the installation rather than just the cost.
