Case Study: Comprehensive Insulation and Rim Joist Sealing for Energy Efficiency in Greenlawn, NY

• Project Location: Greenlawn, NY
• Service Provided: Kitchen Ceiling and Crawl Space Insulation

Client Challenge

A homeowner in Greenlawn, NY, reached out to Zavza Seal LLC to improve the energy efficiency and insulation in their kitchen ceiling and crawl space. The client wanted to reduce energy loss and improve comfort throughout the home, particularly during extreme seasonal temperatures. Addressing insulation in these critical areas—kitchen ceiling and crawl space—was essential to maximize the home’s energy efficiency.

Project Scope and Proposal

To ensure a high standard of insulation and reduce energy loss, Zavza Seal LLC proposed a two-part solution for this project:

1. Kitchen Ceiling Insulation: Enhancing the kitchen ceiling insulation with a cellulose layer to provide an R-value of R49.
2. Crawl Space Insulation and Rim Joist Sealing: Sealing and insulating the rim joists and filling gaps in crawl space insulation to achieve R-values of R21 and R30, respectively, for enhanced thermal resistance.

The key steps involved in each part of the project were as follows:

• Kitchen Ceiling (16′ x 13′):
  1. Cut a 16″ x 16″ access hole in the center of the ceiling.
  2. Blow in cellulose insulation to achieve an R49 insulation value.
  3. Reinstall drywall over the access hole for a seamless finish.
• Crawl Space (500 sq. ft):
  1. Seal and insulate rim joists with spray foam, achieving an R-value of R21.
  2. Install R30 batt insulation in missing sections throughout the crawl space to ensure full coverage.

Implementation Process

Zavza Seal LLC’s experienced technicians followed a meticulous process to deliver a high-quality insulation solution for the homeowner, covering both the kitchen ceiling and crawl space with care and precision.

1. Kitchen Ceiling Insulation Installation
1. Cutting Access: Our team carefully cut a 16″ x 16″ access hole in the center of the kitchen ceiling. This allowed easy access for blowing in cellulose insulation while minimizing disruption to the surrounding ceiling structure.
2. Blowing in Cellulose Insulation: Using specialized equipment, we filled the ceiling area with cellulose insulation, providing an R49 value. This level of insulation significantly reduces heat transfer through the kitchen ceiling, helping regulate the kitchen’s temperature and contributing to lower energy costs.
3. Drywall Repair: Once insulation was complete, we carefully reinstalled drywall over the access hole. Though taping, compounding, and painting were outside the scope, our team ensured the ceiling was prepared for a seamless final touch-up.
2. Crawl Space Insulation and Rim Joist Sealing
1. Rim Joist Sealing with Spray Foam: To address potential energy loss around the rim joists, we applied spray foam insulation. The foam provided an R21 insulation value, sealing gaps to prevent drafts and increase thermal resistance. This step was critical in improving the crawl space’s insulation and reducing air leaks.
2. Installing R30 Batt Insulation: Our team installed R30 batt insulation throughout the 500 sq. ft. crawl space. This ensured consistent coverage, particularly in areas where insulation was previously missing, which reduced energy loss and provided a more consistent thermal barrier for the home.

Project Outcome

Upon completing the insulation upgrades, the homeowner immediately noticed a difference in indoor comfort, particularly in the kitchen and areas above the crawl space. The added insulation in the kitchen ceiling minimized heat transfer, while the sealed and insulated crawl space prevented drafts and increased the home’s overall thermal efficiency.

These upgrades not only improved the homeowner’s comfort but also contributed to long-term energy savings by reducing heating and cooling demands.
