Homeowners across Memphis are asking a simple question: which foam insulation delivers the highest comfort and energy savings for a Mid-South climate? At CountBricks, we answer that question every day—backed by AI-driven estimating, real-time material pricing, and on-site voice data capture. This guide explores the top foam insulation choices Memphis TN residents rely on, how they perform in humid subtropical weather, and how CountBricks streamlines every step from takeoff to invoice.
Summer humidity, winter cold snaps, and year-round temperature swings make insulation a mission-critical component of residential construction in Shelby County. Foam products excel at:
• Creating an air-sealed thermal envelope
• Reducing HVAC cycling and long-term utility costs
• Blocking moisture vapor that fuels mold growth
• Adding structural rigidity to older framing
CountBricks integrates these performance metrics directly into our AI estimate generator, so homeowners see precise payback timelines before the first canister is ordered.
1. R-Value Per Inch: Closed-cell averages R-6.5 while open-cell hovers near R-3.7.
2. Vapor Barrier: Closed-cell forms a built-in vapor retarder—ideal for crawl spaces and rim joists. Open-cell breathes, allowing interior moisture to escape.
3. Expansion Rate: Open-cell expands 100×, filling odd cavities with less material weight. Closed-cell expansion is roughly 30×, creating a denser, heavier layer.
4. Cost Profile: Open-cell typically runs 15-25 % less per board foot in Memphis retail markets. CountBricks’ material-tracking AI reflects live supplier pricing so your quote always mirrors market reality.
Not every bungalow in Cooper-Young or Midtown can accommodate full foam retrofits. CountBricks often recommends hybrid assemblies that combine:
• Flash-and-batt (1" closed-cell plus fiberglass batts) for 2×4 walls
• Open-cell roof decks paired with ridge vents for gable attics
• Closed-cell perimeter band joists and open-cell interior cavities for pier-and-beam homes
Our blueprint takeoff tool highlights where each approach delivers maximum ROI while preserving architectural integrity.
1. Real-Time Voice Walkthrough: Field pros speak measurements into a mobile device; CountBricks captures dimensions instantly.
2. AI Blueprint Takeoff: Upload PDFs and let our engine trace every stud bay and roof pitch in seconds.
3. Live Material Feed: Prices pull from regional distributors hourly, eliminating surprise markups.
4. Labor Allocation: Standard Memphis crew rates auto-populate, yet remain fully editable.
5. Signature-Ready Proposal: Branded PDFs with line-item detail and optional financing link are generated at CountBricks.com/services.
• Always test humidity levels before sealing crawl spaces.
• Integrate closed-cell foam on the warm-side of ductwork to prevent condensation.
• Specify continuous mechanical ventilation when more than 40 % of a home’s shell is sprayed.
CountBricks specs include these requirements automatically, saving builders from costly callbacks.
A 2,200 sq ft ranch built in 1968 struggled with $380 summer power bills. CountBricks performed a voice-activated attic survey, uploaded the existing plan set, and delivered a hybrid open-cell roof deck plus closed-cell gable wall estimate in under 12 minutes. After installation, blower-door testing showed a 48 % leakage reduction, and the homeowner’s average bill dropped to $210. See more success stories at CountBricks.com/portfolio.
• Average open-cell cost in Memphis: $1.05–$1.20 per board foot
• Average closed-cell cost: $1.75–$2.10 per board foot
• Typical 2,000 sq ft attic (open-cell, R-24): $4,800–$5,500 installed
• Payback window at current MLGW rates: 3–5 years
CountBricks updates these numbers daily so your client sees real-world pricing, not last quarter’s averages.
Q: Will foam trap moisture in my older brick walls?
A: CountBricks recommends open-cell in solid masonry to allow drying. We model dew-point migration inside our estimate so you know exactly where vapor will condense.
Q: Can I DIY spray foam?
A: Small kits exist, but consistent density and void-free coverage require pro equipment. CountBricks certified installers guarantee manufacturer-approved application.
Q: Is foam safe around electrical wiring?
A: Yes, as long as wiring is rated 90 °C or higher. CountBricks electricians verify compliance before spraying.

Seasoned contractors know that true performance goes deeper than R-value alone. CountBricks leverages AI analytics to fine-tune every foam specification for Memphis’ unique climate zone 3A.
• Target the Thermal Bypass: Our takeoff highlights rim joists, top plates, and kneewalls—small gaps that create big energy loss. Sealing these zones first can shave 10 % off total project cost while boosting performance.
• Adjust Density by Assembly: CountBricks algorithms recommend 2 lb density closed-cell for below-grade walls but 0.5 lb open-cell for vented attics, balancing structural support with breathability.
• Incorporate Intumescent Coatings: When code requires a 15-minute thermal barrier, we auto-add spray-on coatings to the quote, eliminating mid-project change orders.
