Pittsburgh, PA – Fixing Cathedral Ceiling Comfort with Dense-Pack Insulation Rebecca reached out because her home had high energy bills, drafty rooms, and noticeable temperature swings—especially in areas with cathedral ceilings. These spaces are often some of the hardest areas in a home to properly insulate. Cathedral ceilings don’t have the same open attic space as a traditional attic. That means insulation is confined inside the roof cavities, and if it’s not installed correctly, it leaves gaps where air can move freely. Over time, insulation in these areas can settle or never fully fill the cavity in the first place. That’s exactly what was happening here. Warm air was escaping in the winter, heat was building up in the summer, and the insulation wasn’t stopping airflow the way it should. To fix this, our team used the dense-pack insulation process, which is specifically designed for enclosed cavities like cathedral ceilings. Instead of just adding insulation, we: Dense-packed the cavities to completely fill every void Compressed the insulation to the proper density so air can’t move through it Eliminated hidden gaps that traditional insulation leaves behind Before that, we sealed attic air leaks and penetrations to stop air movement at the source. We also upgraded insulation levels and insulated attic access areas to strengthen the overall system. The key difference with dense-pack in cathedral ceilings is this: You’re not just insulating—you’re controlling airflow inside the structure itself Without dense-pack, air can move through the insulation. With dense-pack, that movement is stopped. The Result Now the cathedral ceiling areas perform the way they should: Temperatures are more consistent Drafts are reduced The home holds heat in the winter and stays cooler in the summer Energy usage is more efficient https://www.ctdrenergysaver.com/attic-insulation/cellulose-insulation.html
