- Fiberglass blown-in is easy to install but seals poorly;
- rigid foam resists moisture but is hard to fit irregular spaces;
- cellulose is eco-friendly but settles;
- choice depends on budget, building needs and long-term savings;
- USA Spray Me's spray foam offers the highest R-value and best thermal performance.
Why Insulation Matters for Your San Francisco Business
SF weather is unpredictable; insulation steadies indoor temperatures, lowers energy costs, improves comfort, dampens noise, prevents moisture and mold, and supports structural integrity. USA Spray Me is SF-based serving Northern California with polyurethane foam.
Types of Insulation for Commercial Properties
Introduces six insulation types.
Fiberglass Insulation
Decent thermal insulation and some soundproofing but falls short of costlier options.
Spray Foam Insulation
High R-value per inch; efficient at insulating and sealing air leaks; versatile, especially for older buildings with many gaps; resists moisture, prevents mold and mildew; strong soundproofing.
Rigid Foam Board Insulation
Used in walls, roofs and foundations; moisture-resistant panels suit damp areas.
Mineral Wool (Rock Wool or Slag Wool)
Fire-resistant with good soundproofing; fits properties prioritizing fire safety and noise reduction.
Cellulose Insulation
Treated with fire retardants; good thermal and sound insulation for a range of commercial uses.
Reflective or Radiant Barrier Insulation
Reflects radiant heat away, reducing heat gain and cooling costs; often used in attics and sun-exposed areas.

Comparison of Insulation Options for Commercial Properties
Comparison table (H4 on page). Estimates at time of writing. Note: spray foam is listed per board foot while the column header says per sq ft.
| Type of Insulation | Cost Range per sq ft | Advantages | Drawbacks |
|---|---|---|---|
| Spray Foam | $1.00 - $4.00 per board foot | High R-value, airtight seal, long-lasting (up to 80 years) | Higher initial cost, professional installation required |
| Fiberglass Blown-in | $0.40 - $1.50 | Energy-efficient, long-lasting, environmentally friendly | Less effective at sealing air leaks, less durable in extreme weather |
| Rigid Foam | $1.20 - $3.00 | High moisture resistance, high R-value per inch | Difficult to fit irregular spaces, careful installation required |
| Cellulose | $0.60 - $2.30 | Environmentally friendly, good thermal performance, noise reduction | Can settle over time; professional installation required |
Choosing the Right Insulation for Your Business
Assess current insulation, find uninsulated areas, choose the best type. Checklist: inspect existing insulation for damage or gaps; identify uninsulated attics, walls, crawl spaces; consider SF's climate (once called a 'temperature paradise', which may no longer hold).

- Identify uninsulated areas
- Consider SF climate
Assessing Your Building's Needs
Contains the assessment steps and checklist above.
Consulting with Professionals
Professionals recommend the right type, ensure proper installation and maximize efficiency.
Professional Maintenance Services
Maintenance keeps insulation in good condition and identifies replacement needs; regular upkeep extends life and savings; most types can last as long as the space is used if cared for.
