Subtopic 4.1088 Special Considerations

Properly restored vents minimize moisture and ice dams

Radiant heat flow reduced

Consistent, uniform thermal boundary Thermal boundary The separation between the interior and exterior environments of a building that slows heat flow between the conditioned space and unconditioned space to prescribed R-value

Properly installed insulation reduces heat flow through parapet wall

Properly installed insulation reduces heat flow through parapet wall

Consistent, uniform thermal boundary Thermal boundary The separation between the interior and exterior environments of a building that slows heat flow and air barrier Air barrier The separation between the interior and exterior environments of a building that slows air flow to the point that no smoke movement is visible at 50 pascals of pressure difference across the boundary between the conditioned space and unconditioned space

Insulation installation does not compromise building durability

Properly restored vents minimize moisture and ice dams

Continuous air and thermal boundary Thermal boundary The separation between the interior and exterior environments of a building that slows heat flow that does not compromise the sprinkler system
