Dave Hoh's Home Comfort & Energy Experts Case Studies: Poorly Insulated Attic in Manalapan Township, NJ

Challenge

In Manalapan Township, NJ, a homeowner faced issues with inadequate attic insulation. Unfortunately, they had paid for a job that didn't meet proper insulation standards, resulting in an improperly insulated space. The attic lacked air sealing, had an insufficient R-Value, and allowed conditioned air to escape into the attic from the adjoining wall. Consequently, the homeowner experienced higher electric bills.

Solution

To address these issues, we took comprehensive measures. We air-sealed the attic floor using orange ZypFoam, sealed the ducts with mastic tape, encapsulated the ducts as necessary, and installed SilverGlo foam boards on the adjoining wall, sealing them with orange ZypFoam. This meticulous approach ensures that conditioned air no longer leaks into the attic from the rooms below and the adjoining wall. Furthermore, we built retaining walls specifically designed to confine the blown-in TruSoft cellulose insulation, providing it with an impressive R-value of R-60. As a result of these improvements, the homeowner now enjoys increased comfort and energy efficiency in their home.

Project Summary

Products Used: SilverGlo, ZypFoam, TruSoft Cellulose Insulation

The attic floor lacks proper air sealing, and the ducts aren't appropriately sealed either. We've taken steps to address this by using mastic tape to encapsulate the necessary ducts. Additionally, the adjoining wall (back wall) lacks proper insulation, leading to conditioned air leaking into the attic.

We used TruSoft Cellulose insulation and blew it in to reach the recommended R-value, ensuring the customer has sufficient insulation.

We used orange ZypFoam sealant to air seal the attic and built retaining walls to contain the TruSoft Cellulose insulation. Additionally, we constructed a catwalk to facilitate access for both customers and technicians to reach any mechanicals in the attic.

The adjoining wall (back wall) was allowing conditioned air to escape into the attic. To tackle this, we installed SilverGlo Foam panels and used orange ZypFoam sealant for air sealing. Additionally, we insulated the attic and buried the ducts with TruSoft insulation. These combined techniques will effectively prevent further air leakage into the attic, ultimately assisting the customer in saving money on their electric or energy bills.
