Here is a quick look at how the 4 most common insulation options work best:
• Fiberglass Batts: A budget-friendly, widely used option ideal for standard interior walls, floor joists, and simple framing cavities.
• Blown-In Cellulose: An eco-friendly material made from recycled paper, excellent for topping off attic insulation and dampening sound between rooms.
• Rigid Foam Boards: Dense, moisture-resistant panels built for continuous exterior coverage, basement walls, and under concrete slabs before a pour.
• Spray Foam: Expands to seal gaps and create a seamless air and moisture barrier—making it a go-to choice for metal post-frame buildings, heated shops, and barndominiums.
Understanding how each material performs helps you make the best choice for your structure and long-term energy goals.
