Convective Loops
- Improper installation of conventional insulation, light density blown-in insulation and structural items such as a drop soffit in the kitchen can create a convective loop. A convective loop, whether inside a wall cavity or in another building assembly, occurs when air rises along a warm surface and falls along a cold surface, creating a circular movement of warm and cold air. A convective loop transfers heat through the building assembly, requiring more energy to replace the lost heat in heating seasons and the lost cool air in cooling seasons.
