Knee Wall Insulation
Fix Boiling Hot Summers & Freezing Winters in Upstairs Bedrooms & Bonus Rooms
What Is A Knee Wall?
A knee wall is a short vertical wall (typically 3 to 5 feet high) that connects your living space floor to the sloping roof rafters in 1.5-story homes, Cape Cods, and finished attic bonus rooms.
Behind every knee wall is an unconditioned, scorching hot or freezing cold attic space. In older homes across Lee's Summit, Raytown, and Overland Park, these walls suffer from unsealed air leaks, causing extreme room temperature swings.
How Star Companies Fixes Knee Walls:
1. Rigid Backing Installation
We cap the back of open knee wall studs with rigid foam board so insulation stays permanently held against the wall face.
2. Precision Air Sealing
Sealing top and bottom plates, wire penetrations, and joist cavities under the knee wall to stop hot attic air from flowing underneath room floors.
3. High R-Value Fiberglass / Spray Foam
Installing Owens Corning PINK® batts or Thermoseal spray foam for maximum thermal resistance against summer heat radiation.
