🏡 Upgrade Your Home’s Energy Efficiency from the Outside In! 🏡
Did you know adding 1/2” fan fold insulation or 3/4” foam sheathing to the exterior of your home can make a big difference in comfort and energy savings?
✅ Reduces thermal bridging through wall studs
✅ Improves overall wall R-value
✅ Helps keep your home warmer in winter and cooler in summer
✅ Creates a smoother surface for new siding installation

Whether you’re replacing siding, remodeling, or building new, exterior foam insulation is an affordable way to improve your home’s performance before the new siding goes on.
The photos below show a home wrapped with foam sheathing before siding installation—a simple upgrade that pays dividends for years to come.
