We help homeowners and builders create healthier, more efficient homes with professional crawlspace solutions built to last!
Protect Your Home from the Ground Up
Your crawlspace plays a huge role in your home’s comfort, air quality, and energy efficiency. If it’s not properly sealed and insulated, it can become a major source of moisture, mold, and energy loss.
At EM² Insulation, we specialize in crawlspace encapsulation systems that create a clean, dry, and energy-efficient foundation for your home.
Why Crawlspaces Are a Problem
Most crawlspaces are:
- Damp or humid
- Poorly insulated
- Open to outside air
- A breeding ground for mold and pests
Up to 40% of the air you breathe inside your home can come from your crawlspace.
That means whatever is down there—moisture, mold, odors—can end up in your living space.
Why Fiberglass Is NOT the Right Choice
Fiberglass insulation works by slowing heat transfer—but it does nothing to stop air movement, which is where most energy loss actually happens.
Fiberglass insulation is commonly used in crawlspaces—but in most cases, it actually causes more problems than it solves.
Here’s what people are realizing:
It doesn’t air seal
Air leaks around wiring, framing, and gaps allow outside air to flow right through—even if fiberglass is installed.
Performance depends on perfect installation
If it’s compressed, gapped, or poorly fitted (which happens often), its effectiveness drops significantly.
It’s affected by moisture
In areas like crawlspaces, attics, and basements, humidity can reduce performance and lead to issues over time.
It settles and shifts
Over time, fiberglass can sag or move, leaving areas unprotected.
Bottom line: Fiberglass was never designed for crawlspace environments
The Right Solution: Crawlspace Encapsulation
Why Homeowners Are Moving Away from Fiberglass
For years, fiberglass insulation was the standard—but today, more homeowners and builders are choosing spray foam because it solves problems fiberglass simply can’t. Encapsulation seals your crawlspace from the ground and outside air, turning it into a controlled, dry environment.
Why Spray Foam Is Taking Over
Spray foam isn’t just insulation—it’s an air seal + moisture barrier + insulation all in one.
That’s the game changer.
- Heavy-duty vapor barrier installation
- Sealing vents and air leaks
- Insulating walls
- Moisture control solutions
Our process includes: The Big Shift in the Industry
Builders and homeowners are realizing:
Insulation alone isn’t enough—you need air sealing
That’s why spray foam has become the preferred solution in:
- New construction
- Energy-efficient homes
- High-performance upgrades
Benefits of Encapsulation
- Lower energy bills
- No more musty smells
- Protection against mold and mildew
- Increased home comfort
- Longer life for your HVAC system
Why Spray Foam Works Better
Unlike fiberglass, spray foam:
- Air seals and insulates in one step
- Does not absorb moisture
- Stays in place permanently
- Creates a continuous barrier
Fiberglass can still work in certain situations—but for maximum efficiency, comfort, and long-term performance, spray foam is the better investment.
This is why it’s one of the best solutions for crawlspaces when done correctly.
