A Better-Insulated Attic Starts with Better Airflow

Bathroom paint peeling is often a sign of a bigger attic ventilation or moisture issue. For this home, our Dr. Energy Saver team helped address the problem at the source by improving attic insulation, extending the bath fan duct properly through the roof, installing a scuttle cover, and adding baffles to support proper airflow throughout the attic. The result: a more efficient, better-ventilated attic system designed to help reduce moisture problems, protect the home, and improve comfort year-round. Small signs inside the home can point to big opportunities above the ceiling.

Attic Insulation Removal & SuperAttic Upgrade - Glenview, IL

This Glenview homeowner was experiencing temperature swings, poor attic usability, and limited storage space—common issues caused by outdated insulation and vented attic conditions. We completed a targeted attic upgrade designed to improve energy efficiency, home comfort, and usable storage space. First, we carefully removed existing cellulose insulation only in the areas required to extend the attic decking, preserving the remaining insulation wherever possible. Next, we converted the space into a SuperAttic system by installing 4" SilverGlo foam board along the roof rafters. The system was fully air sealed using Zyp Foam to create an airtight, conditioned attic. This approach helps reduce energy loss, improve indoor comfort year-round, and maintain proper roof ventilation by keeping the roof deck cold in winter. Finally, we installed and extended attic decking to both the front and back of the attic, creating safe, functional storage space for the homeowner.

From Sparse Insulation to Full Attic Coverage

This Palatine attic went from uneven, underperforming insulation to a cleaner, more complete attic insulation system. Our Dr. Energy Saver team added fresh blown-in cellulose insulation to help improve energy efficiency, reduce heat loss, and support a more comfortable home year-round. A properly insulated attic can make a big difference in how the home feels — especially during Midwest winters and hot summer months. Small upgrades above the ceiling can lead to better comfort throughout the entire home.
