Why Frozen Pipes Are a Winter Threat

Every winter, thousands of homeowners face the nightmare of burst pipes. When water inside a pipe freezes, it expands, causing pressure that can split copper or PVC. A single burst pipe can release up to 250 gallons of water per day, leading to flooding, drywall damage, and expensive repairs. According to the Insurance Institute for Business & Home Safety (IBHS), pipe bursts are one of the leading causes of winter home damage.

For additional homeowner guidance, the U.S. Department of Energy (DOE) emphasizes that insulating exposed water lines is one of the most effective ways to prevent freezing and reduce heat loss. (energy.gov – Insulate Hot Water Pipes)

How Cold Air Reaches Your Plumbing

Pipes in uninsulated crawl spaces, basements, attics, and exterior walls are most vulnerable. Cold outdoor air seeps in through:

• Gaps around foundation walls and sill plates

• Vents and cracks in crawl spaces

• Poorly sealed attic floors

  
  

Even a small draft can lower surrounding temperatures enough to freeze water lines during a cold snap. The DOE’s Building America Solution Center also identifies crawl spaces as a major risk area for heat loss and freezing pipes. (basc.pnnl.gov – Unvented, Insulated Crawlspaces)

Why Traditional Insulation Falls Short

Fiberglass batts and foam boards only slow down heat loss, they don’t stop air movement. Once cold air enters through a gap or seam, these materials can’t block it. As a result, pipes behind traditional insulation can still freeze if air leaks aren’t sealed.

The DOE’s “Insulating Plumbing Pipes” guide highlights the importance of sealing air leaks before insulating plumbing for maximum freeze protection. (basc.pnnl.gov – Insulating Plumbing Pipes)

How Spray Foam Protects Pipes

Spray foam insulation acts as a thermal and air barrier in one.

• Seals air leaks: Expands to fill cracks around pipes, walls, and rim joists.

• Maintains stable temps: Prevents cold air from reaching plumbing lines.

• Adds strength: Closed-cell spray foam even adds rigidity and moisture resistance to the structure.

  
  

By keeping cold air out and warm air in, spray foam drastically reduces the risk of frozen or burst pipes in winter.

Bonus Benefits: Efficiency & Comfort

Beyond pipe protection, spray foam offers year-round advantages:

• Lower energy bills through reduced heat loss

• Consistent indoor temperatures

• Less moisture buildup, preventing mold and mildew

• Greater comfort in basements, garages, and crawl spaces

  
  

Final Thoughts: Winterize Smart

Frozen pipes aren’t just inconvenient, they’re preventable. With spray foam insulation, you can seal off your home’s most vulnerable areas, protect your plumbing, and enjoy a warmer, more efficient home this winter.
