Natural vs Synthetic Insulation: R-Value & Cost Compared
Compare natural and synthetic insulation by R-value per inch, cost per sq ft, moisture resistance, and lifespan. Data for wool, cellulose, fiberglass, and foam.
Natural vs Synthetic Insulation: Cost and Efficiency Comparison Looking to insulate your home? Here's what you need to know: Natural Insulation: Eco-friendly options like cellulose, sheep's wool, hemp, and cork. They manage moisture well, last up to 80 years, and cost less upfront. However, some may need thicker applications or extra care in humid areas. Synthetic Insulation: Includes fiberglass, spray foam, and foam boards. Offers higher R-values (better thermal performance) and strong air-sealing properties but often comes with higher environmental costs. Quick Comparison: | Feature | Natural Insulation | Synthetic Insulation | |---------|-------------------|---------------------| | R-Value (per inch) | 3.0–4.0 | 2.5–6.0 | | Cost | Moderate | Varies (fiberglass is cheaper; spray foam is costly) | | Moisture Management | Excellent | Varies (foam resists moisture; fiberglass struggles) | | Environmental Impact | Lower | Higher | | Durability | ~80 years | ~20–50 years | Key Takeaway: N...
