Project Size: ~3,885 sq. ft. of insulation coverage + optional basement work
Materials Used: EcoBatt Faced Fiberglass Insulation with ECOSE® Technology

Zavza Seal LLC was contracted to provide expert insulation and air sealing solutions for a residential property in Westbury, NY. The client sought to enhance the home’s energy efficiency, interior comfort, and seasonal thermal performance. Our team executed a multi-zone insulation strategy and meticulous air sealing to exceed expectations in performance and sustainability.

Scope of Work

🔷 Ceiling Insulation

• Area Covered:Approx. 3,100 sq. ft.
• Materials Used:
  • R-30 EcoBatt for standard joist bays (~1,300 sq. ft.)
  • R-15 EcoBatt for smaller ceiling areas (~1,800 sq. ft.)

Our team installed fiberglass insulation with ECOSE® Technology between exposed ceiling joists. Where R-30 insulation could not fit due to space constraints, R-15 EcoBatt was used, ensuring consistent thermal performance throughout the ceiling structure.

🔷 Exterior Wall and Ceiling Insulation (Selective Zones)

• Area Covered: Approx. 500 sq. ft.
• Material Used: R-21 EcoBatt Fiberglass Insulation

Selective ceiling and wall areas required the higher-density R-21 insulation to meet building codes and thermal targets. These were carefully placed in cavities prone to heat loss.

🔷 Ventilation Enhancements

• Component Installed: Rafter Baffles
• Coverage: Approx. 60 Linear Feet

To support proper airflow and ventilation, rafter baffles were installed from the soffit area, preventing insulation blockages and ensuring long-term system performance.

🔷 Comprehensive Air Sealing

We conducted full air sealing for all exterior walls, rim joists, and wall penetrations using expanding spray foam. All window frames were sealed and neatly trimmed, preparing the space for future drywall installation while minimizing air infiltration.

Optional Add-On: Basement Ceiling Insulation

• Area Covered: Approx. 285 sq. ft.
• Material Proposed: R-30 EcoBatt Kraft Faced Fiberglass

As an optional upgrade, we proposed insulating the basement ceiling to further enhance thermal comfort and reduce energy loss from below living areas.
