High-Performance Spray Foam Insulation for Maximum Energy Efficiency

Seal air leaks, improve indoor comfort, and increase year-round energy savings with professional spray foam insulation solutions.

R-Values, Performance & Energy Efficiency Benefits

High-Performance Spray Foam Insulation is one of the highest-performing insulation solutions available for homes looking to improve energy efficiency, reduce air leakage, and create better year-round indoor comfort. In Colorado homes, spray foam is commonly used in attics, crawl spaces, wall cavities, rim joists, garages, and new construction projects where stronger thermal performance is needed.

Closed-cell spray foam commonly delivers between R-6 to R-7.5 per inch, while open-cell spray foam averages around R-3.5 to R-3.8 per inch, depending on the product and installation depth.

What Is Spray Foam Insulation?

Spray foam insulation is applied as a liquid that rapidly expands to seal gaps, cracks, and open cavities. Unlike traditional insulation materials, spray foam helps create an air-tight barrier that reduces heat transfer and minimizes unwanted airflow throughout the home.

Because it expands into difficult-to-reach areas, spray foam is often used where stronger air sealing and moisture control are important.
Spray foam can help:
  • Reduce heating and cooling costs
  • Improve indoor comfort year-round
  • Minimize drafts and air leakage
  • Improve moisture resistance
  • Support HVAC efficiency
  • Reduce outside noise transfer

Open-Cell vs Closed-Cell Spray Foam

Open-Cell Spray Foam

Open-Cell foam is lighter, softer, and designed to expand aggressively to fill deep framing cavities. It provides an exceptional air barrier and superior sound dampening while remaining flexible.

Typical Open-Cell R-Value:
  • Approximately R-3.5 to R-3.8 per inch
Common Uses:
  • Interior wall cavities & home theaters (for advanced soundproofing)
  • Exterior walls (in standard, well-vented framing)
  • Clean, conditioned attic conversions (where a vapor barrier is not required)
Closed-Cell Spray Foam

Closed-Cell foam is dense, rigid, and acts as a heavy-duty thermal, air, and moisture barrier. It hardens to add structural integrity to the building envelope and will not absorb water.

Typical Closed-Cell R-Value:
  • High-Performance of R-6 to R-7.5 per inch.
Common Uses:
  • Crawl spaces & damp basements
  • Rim joists & exposed framing
  • Rooflines and unvented attic rafters
  • Maximizing R-value in tight framing spaces

Understanding Spray Foam R-Values

R-value measures how effectively insulation resists heat transfer. The higher the R-value, the stronger the insulation performance.

Spray foam delivers higher thermal performance per inch compared to many traditional insulation materials. Because of this, it is commonly chosen for homes where space is limited but strong insulation performance is required.

For Colorado homes, attic insulation recommendations commonly range between:

  • R-49 minimum
  • R-60 recommended for higher elevations or advanced energy upgrades



Wall insulation recommendations commonly range between:

  • R-13 to R-21
    
depending on framing depth and construction type.

Spray Foam for New Construction & Remodels

Spray foam insulation is commonly used in custom homes, additions, remodels, and high-performance building projects where stronger energy efficiency goals are desired.

Because spray foam expands directly into framing cavities, it can help builders and homeowners create tighter, more energy-efficient structures compared to traditional insulation alone.

Signs Your Home May Benefit From Spray Foam

You may want to consider spray foam insulation if you notice:

  • High utility bills
  • Drafty rooms
  • Uneven indoor temperatures
  • Hot upstairs rooms during summer
  • Excessive attic heat
  • Moisture or humidity issues
  • Rooms difficult to heat or cool
  • Older insulation with poor performance

Frequently Asked Questions

What is the difference between open-cell and closed-cell spray foam, and which do I need?

The main differences are density, R-value, and moisture resistance. Closed-cell spray foam is dense and rigid, delivering a high-performance R-6.0 to R-7.5 per inch. It cures into a rock-hard barrier that completely rejects water, making it the premier choice for crawl spaces, rim joists, and unvented rooflines. Open-cell spray foam is lighter and more flexible, averaging R-3.5 to R-3.8 per inch. It expands aggressively to fill deep cavities, acting as an exceptional air barrier and sound-dampening material—ideal for interior walls, home theaters, and clean, conditioned attics.

Yes, absolutely. Ice dams are caused when warm air escapes from your home into the attic, heating up the roof deck and melting the snow above. That melted water runs down to your cold gutters, where it refreezes into a dangerous ice dam. By applying spray foam insulation directly to your attic floor or roofline, we create a seamless air barrier that stops indoor heat from escaping. This keeps your roof deck uniformly cold and completely eliminates the root cause of ice damming.

It depends entirely on the type of foam used. Because closed-cell spray foam is incredibly dense and tightly packed, it naturally acts as its own approved vapor barrier once it reaches an installation depth of 2 inches. If you use closed-cell foam in moisture-prone zones like crawl spaces, no additional plastic vapor barrier is needed on the framing. Open-cell spray foam, however, has a more porous structure; while it blocks airflow completely, it allows vapor to pass through, meaning a separate vapor retarder may still be required depending on your local building code and specific application.

Our high-performance spray foam formulations cure rapidly upon application. However, during the spraying and initial off-gassing phase, homeowners, children, and pets must vacate the property. For standard residential projects, it takes 24 hours for the chemical reaction to completely finish and clear out safely with our active site ventilation. After this 24-hour window, the foam is completely inert, non-toxic, and safe for everyone to return to a radically more comfortable home.
