Problem:

A homeowner in Flushing, NY reached out to Zavza Seal because their home was experiencing uneven indoor temperatures. During the winter, the upstairs rooms were noticeably colder, while the home became uncomfortably warm during the summer. Their energy bills were consistently high, and they suspected the attic insulation was outdated and underperforming.

After a full inspection, our team confirmed that the attic floor still contained old batt insulation that had deteriorated over time. Much of it had shifted out of place, lost density, and no longer provided an effective thermal barrier. The attic rafters were open and untreated. Without proper insulation along the roof rafters, heat transfer was significant. This was causing energy loss, poor temperature control, and unnecessary stress on the HVAC system.

The homeowner wanted a long term insulation solution that:

• Improved year round comfort
  
• Lowered energy consumption
  
• Offered stronger air sealing
  
• Would not require frequent replacement
  

They trusted Zavza Seal to deliver a reliable, modern insulation upgrade.

Solution:

Our team performed a complete attic insulation removal and spray foam installation across approximately 1,150 square feet of attic rafter space.

1. Removing Old Batt Insulation

The project began with the safe removal of the existing batt insulation from the attic floor. We bagged and disposed of the old material properly to ensure a clean, dust free work environment for the homeowner.

2. Preparing Rafters for Spray Foam Application

Once the floor insulation was removed, we inspected and confirmed that the 2×6 roof rafters were spaced 16 inches on center and fully accessible. This created the perfect layout for a uniform spray foam application.

3. Installing Closed Cell Spray Foam Insulation

We applied high quality closed cell spray foam insulation between the rafters to achieve an R value of 24.5. Closed cell foam was selected for this project because it provides:

• A high R value per inch
  
• Superior air sealing
  
• Moisture resistance
  
• Long term stability

This type of insulation creates a tight thermal envelope, preventing conditioned air from escaping and blocking outside air from entering.

4. Final Sealing and Quality Check

After the foam cured, our team performed a full inspection of the attic space. We checked for proper expansion, adhesion, and coverage to ensure consistent insulation depth throughout.

Results:

The Flushing homeowner immediately noticed improvements in indoor comfort and temperature stability. The new spray foam insulation dramatically reduced heat transfer through the roof, helping the home stay warmer in winter and cooler in summer.

Key benefits included:

• Reduced energy loss
  
• Lower monthly utility bills
  
• A stronger and more efficient HVAC system
  
• Improved indoor comfort throughout the home
  
• Long lasting insulation performance
  

This upgrade created a healthier, more efficient, and more comfortable living environment for the homeowner.
