HFC vs. HFO
HFC vs HFO Closed Cell Spray Foam: What’s the Difference and Why It Matters in Mid Michigan
If you’re researching closed cell spray foam insulation in Mid Michigan, you may not realize that the performance of spray foam depends on more than just thickness or R-value. One of the most important — and often overlooked — differences is the blowing agent used in the foam.
Closed cell spray foam is typically made using either HFC (Hydrofluorocarbon) or HFO (Hydrofluoroolefin)technology. While both create insulation, HFO closed cell spray foam is the clear modern standard and offers significant advantages over older HFC products.
At Mid Michigan Spray Foam, we choose to use HFO closed cell spray foam exclusively, because it delivers better long-term performance, environmental responsibility, and value for our customers.
What Is Closed Cell Spray Foam Insulation?
Closed cell spray foam insulation is a dense, rigid insulation material that expands on application and cures into a continuous barrier. It provides three critical functions at once:
High R-value insulation
Air sealing
Vapor control
With an R-value of approximately 6.5–7 per inch, closed cell spray foam is ideal for Michigan’s cold climate, where controlling heat loss, moisture, and air leakage is essential.
Understanding the Difference Between HFC and HFO Spray Foam
HFC Closed Cell Spray Foam (Older Technology)
HFC-based spray foam uses hydrofluorocarbon blowing agents that were widely used for many years. While HFC spray foam can still function as insulation, it comes with several limitations compared to newer products.
Limitations of HFC spray foam:
Very high Global Warming Potential (GWP)
Older chemistry that is being phased out
Less environmentally responsible
Not considered future-proof
Why do some competitors still use HFC spray foam?
The primary reason is cost. HFC closed cell spray foam is cheaper for contractors to purchase, which allows some companies to offer lower prices or maintain higher profit margins. However, the lower upfront material cost does not translate to better performance or long-term value for the homeowner.
HFO Closed Cell Spray Foam (Next-Generation Technology)
HFO closed cell spray foam uses advanced hydrofluoroolefin blowing agents designed to meet modern building and environmental standards.
Benefits of HFO spray foam insulation:
Ultra-low Global Warming Potential (near zero)
Same or better R-value than HFC foam
Improved long-term thermal stability
Compliant with current and future EPA regulations
Better choice for energy-efficient homes
HFO technology represents the current best practice in closed cell spray foam insulation.
Why HFO Closed Cell Spray Foam Is Better for Mid Michigan Homes
Homes in Mid Michigan face long heating seasons, temperature swings, and moisture challenges. HFO closed cell spray foam performs exceptionally well in these conditions because it:
Maintains insulation value over time
Acts as an effective air and vapor barrier
Reduces condensation risk in walls and attics
Helps lower heating and cooling costs
Improves overall indoor comfort
This makes HFO closed cell spray foam ideal for:
Attics and roof decks
Basements and crawl spaces
Pole barns and metal buildings
Garages and workshops
Exterior wall insulation in cold climates
Why Using HFO Makes Mid Michigan Spray Foam Different
When searching for spray foam insulation contractors in Mid Michigan, many companies appear similar on the surface. However, the materials they use can vary significantly.
At Mid Michigan Spray Foam, we made a deliberate decision to use HFO closed cell spray foam instead of cheaper HFC products. This decision reflects our focus on quality, performance, and long-term results.
What This Means for Our Customers:
Higher-quality insulation systems
Materials that meet modern environmental standards
Better long-term performance and durability
A future-ready insulation solution
No shortcuts taken to reduce costs
While some competitors continue using HFC spray foam to keep material costs lower, we believe homeowners deserve the best available technology, not outdated products chosen primarily for price.
Final Thoughts
Not all closed cell spray foam insulation is created equal. The difference between HFC and HFO spray foam can impact your home’s energy efficiency, environmental footprint, and long-term value.
By choosing HFO closed cell spray foam, Mid Michigan Spray Foam delivers a higher standard of insulation — one designed for Michigan’s climate and the future of building performance.
If you’re looking for high-quality spray foam insulation in Mid Michigan, choosing a contractor that uses HFO technology truly makes the difference.
