Is Spray Foam Worth It? The Stanley Cup Theory of Home Insulation
Paper Cup Insulation
Holds the liquid — but your drink is room temperature in 20 minutes. Fiberglass fills the cavity but lets air and energy escape freely.
Stanley Cup Insulation
Maintains the environment inside — all day, every day. Spray foam seals every gap and keeps your home exactly where you set the thermostat.
The Stanley Cup Theory: Why Spray Foam Is Worth It
Is spray foam worth it? Eric Stimach from Seal Tech Insulation and John Bujak of America's Home Experts use one of the best analogies in home performance to answer that question: the Stanley Cup vs. the paper cup.
You can use a paper cup or a Stanley Cup — both hold liquid. But only one maintains the environment inside. A paper cup works for five minutes. A Stanley Cup keeps your drink cold for 24 hours. The same principle applies to your home's insulation. Fiberglass batts fill a wall cavity, but they don't stop air from moving through them. Spray foam is worth it because it expands to seal every gap, crack, and penetration — maintaining the environment inside your Ann Arbor home the way a Stanley Cup maintains the temperature of your drink.

Video Summary — Eric Stimach & John Bujak, America's Home Experts
The setup: John Bujak of America's Home Experts asks Eric Stimach why spray foam costs roughly 40% more than fiberglass — and whether Ann Arbor homeowners should care about that price gap.
The Stanley Cup analogy: Eric explains that you can use a paper cup or a Stanley Cup — both hold liquid, but only one maintains the environment inside. Fiberglass fills a wall cavity, but air moves through it freely. Spray foam expands and seals, maintaining your home's interior environment the way a Stanley Cup maintains your drink's temperature.
The price gap explained: The 40% price premium for spray foam over fiberglass comes from superior chemical performance — not just higher R-value per inch, but the air sealing and vapor control that fiberglass physically cannot provide. You're not paying 40% more for the same thing. You're paying for a fundamentally different product.
The ROI for Ann Arbor homeowners: Ann Arbor homeowners who choose spray foam are investing in long-term air sealing over the lowest upfront bid. The energy savings, comfort improvement, and lifetime durability of spray foam make it worth it — especially in Michigan's Climate Zone 5 where heating loads are extreme.
The bottom line: Stop settling for "paper cup" insulation. If you want your home to maintain the environment inside — year after year, through Michigan winters and humid summers — spray foam is worth it.

The 40% Price Gap: What You're Actually Paying For
Spray foam costs roughly 40% more than fiberglass insulation. Here's exactly what that premium buys you:
Fiberglass Batts — "Paper Cup"
- Fills the cavity only
- Air passes through freely
- R-2.2 to R-3.2 per inch
- Settles and loses R-value over time
- Needs replacing every 15–25 years
- No vapor control
- No structural benefit
Spray Foam — "Stanley Cup"
- Expands to seal every gap & crack
- Creates continuous air barrier
- R-3.5 to R-7 per inch
- Never settles — maintains R-value for life
- Lasts 80–100+ years
- Class II vapor retarder (closed-cell)
- Adds structural rigidity
Is Spray Foam Worth It for Ann Arbor, MI Homes?
Ann Arbor sits in IECC Climate Zone 5 — Michigan's most demanding heating climate. Average January lows of 16°F, 100+ freeze-thaw cycles per year, and humid summers mean your insulation is working hard in both directions. In this climate, the air sealing performance of spray foam is worth it because the energy savings are measurably greater than in milder climates. Ann Arbor homeowners who invest in spray foam are choosing long-term performance over the lowest upfront bid — and the math backs them up.
Spray Foam Worth It: The Long-Term ROI Breakdown
| Factor | Spray Foam ("Stanley Cup") | Fiberglass ("Paper Cup") |
|---|---|---|
| Upfront cost | ~40% higher | Lowest |
| Air sealing | ✅ Complete — expands to fill every gap | ❌ None — air passes through freely |
| Energy savings | 30–50% reduction in heating/cooling | 10–20% reduction |
| Lifespan | 80–100+ years | 15–25 years (settles) |
| Replacement cost | $0 — never needs replacing | Full reinstall cost every 20 years |
| Comfort improvement | ✅ Dramatic — no drafts, no cold spots | Moderate |
| Payback period | 3–7 years (Ann Arbor average) | N/A — savings too small to calculate |
| Total cost of ownership | ✅ Lowest over 30+ years | Higher (energy waste + replacement) |
Why Ann Arbor Homeowners Choose Spray Foam Over the Lowest Bid
The most common mistake Ann Arbor homeowners make when insulating is choosing the lowest upfront bid without considering total cost of ownership. Fiberglass looks cheaper on the quote — but when you factor in the energy waste over 20 years, the replacement cost, and the comfort problems that never get solved, the paper cup ends up costing more than the Stanley Cup.
Seal Tech's Ann Arbor customers consistently report the same thing after spray foam installation: their home finally feels comfortable. Not just "a little better" — dramatically different. No more cold spots near windows. No more drafts in the basement. No more rooms that won't stay warm no matter how high you set the thermostat. That comfort improvement is what makes spray foam worth it — and it's something fiberglass simply cannot deliver.
