The Complete Guide to Attic Insulation for Tulsa Homes

Why Attic Insulation Matters Most

In most homes, the attic is responsible for up to 25% of energy loss. Hot air rises, and in winter, your heated air escapes right through an underinsulated attic. In summer, Oklahoma's brutal sun superheats your attic to 150°F or more, radiating heat into your living space.

Current Oklahoma Building Codes

The International Energy Conservation Code (IECC), adopted by Oklahoma, recommends:

- R-38 to R-60 for attic insulation in our climate zone

• Many older Tulsa homes have only R-19 or less
• Upgrading to code compliance can reduce energy costs by 20-30%

  Types of Attic Insulation

  #### Fiberglass Batts

  The traditional choice found in most homes. Pros: affordable upfront. Cons: degrades over time, doesn't seal air leaks, loses effectiveness when compressed or wet.

  #### Blown-In Fiberglass or Cellulose

  Better coverage than batts, fills gaps more effectively. Still doesn't address air sealing and can settle over time.

  #### Spray Foam Insulation

  The premium option. Creates an air-sealed barrier with the highest R-value per inch. Doesn't settle or degrade. Ideal for Oklahoma's extreme temperatures.

  Open Cell vs Closed Cell for Attics

  For Tulsa attics, we typically recommend closed cell spray foam because:

  - Higher R-value means better protection against summer heat

• Acts as a moisture barrier against humidity
• Adds structural rigidity to roof decking
• Resists mold and pest infiltration

  However, open cell can be appropriate for:

  - Budget-conscious projects

• Situations where vapor permeability is desired
• Achieving thick coverage at lower cost

  The Spray Foam Attic Process

  1. Assessment: We inspect your attic for existing insulation condition, ventilation, and air leaks

2. Preparation: Remove old insulation if necessary, seal obvious penetrations 3. Application: Professional application of spray foam to recommended thickness 4. Inspection: Quality check to ensure complete coverage and proper depth 5. Clean-up: We leave your home as clean as we found it

Cost Considerations

While spray foam costs more initially, consider:

- 30-50% reduction in energy bills

• 20+ year lifespan vs 10-15 for other materials
• No maintenance or replacement costs
• Increased home resale value
• Potential rebates from utility companies

  Common Questions

  Will spray foam make my attic too hot?

No—properly installed spray foam keeps attic temperatures much closer to outside ambient temperatures, reducing the heat load on your home.

Do I need to remove old insulation first? It depends on condition. Moldy, wet, or pest-damaged insulation should be removed. Clean, dry existing insulation can sometimes be supplemented.

How long does installation take? Most residential attics can be completed in one day.
