The Problem
The homeowner in Manhasset was dealing with poor insulation in the second-floor wall area located below the mansard roof. This section of the home was approximately 944 square feet and was allowing heat loss, outside noise, and inconsistent indoor temperatures.
Over time, this type of insulation gap can lead to:
- higher energy bills
- uncomfortable room temperatures
- outside noise entering the home
- reduced overall energy efficiency
The wall cavity had limited insulation, and the homeowner wanted a solution that would improve comfort while also making the home more energy efficient.
Our Solution
Our team at Zavza Seal accessed the wall cavity through the existing opening in the mansard enclosure at the floor level. This allowed us to reach the interior wall space without unnecessary disruption to the home.
We then installed blown-in cellulose insulation throughout the wall cavity.
This material was chosen because it provides strong thermal performance and long-term stability inside wall systems.
What We Did
- Accessed the wall cavity from the mansard floor opening
- Inspected the available cavity space
- Installed blown-in cellulose insulation across approximately 944 sq. ft.
- Ensured full and even coverage inside the wall system
- Sealed and secured access points after installation
After installation, the homeowner experienced noticeable improvements in:
- indoor temperature stability
- reduction in outside noise
- overall home comfort
- energy efficiency performance
The upgraded insulation now helps reduce heat loss in winter and heat gain in summer.
