🏡 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
✅ Can help lower heating and cooling costs

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.

At Source Mountain Supply, we stock exterior insulation solutions for contractors, builders, and homeowners.

🚧 Geofoam in Action: Pool Infill Project for JP Cullen 🚧

A recent project using EPS Geofoam to fill an existing pool demonstrates why more contractors and engineers are turning to geofoam for challenging fill applications.

Instead of hauling in and compacting thousands of pounds of traditional fill material, EPS Geofoam provides a lightweight solution that helps reduce loads on surrounding soils while speeding up installation.

Benefits of Geofoam for Pool Infill:

✅ Lightweight – significantly reduces weight compared to soil or aggregate

✅ Fast Installation – large blocks can be installed quickly

✅ Minimal Equipment Required

✅ Reduces Settlement Concerns

✅ Easy to Cut and Customize On-Site

✅ Ideal for pool removals, embankments, bridge approaches, retaining walls, and poor soil conditions

This project transformed an unused pool area into usable space while minimizing the risk of future settlement.

If you're working on a project involving pool infill, poor soils, slope stabilization, or structural fill applications, I'd be happy to discuss how EPS Geofoam can help.

📦 Packaging That Reflects the Standard Behind the Product

At Source Mountain Supply, LLC., we believe every detail matters—including how materials arrive on site.

That’s why our poly bag packaging isn’t just packaging—it’s a reflection of how we do business:

✔️ Clean, consistent protection for materials in transit
✔️ Moisture and debris resistance to help ensure product integrity
✔️ Easy handling and identification for jobsite efficiency
✔️ Professional presentation that matches the quality inside

From the warehouse to the jobsite, we take pride in delivering materials that are protected, organized, and ready to perform.

Because in construction, the way something is packaged says a lot about the company behind it.

🏔️ Built with care. Delivered with purpose.
