Typical gap shapes considered include straight through.

Estimating air leakage through doors for smoke control.

Applications for prediction and design appropriate to smoke control systems are indicated. Baffle at leading edge. Realistic smoke leakage control was investigated using actual scale through penetration firestop models installed in a curtain wall and air leakage measurement units. And filament brush seal.

Estimating air leakage through doors for smoke control. Baffle at leading edge. Knowledge of air leakage is also of importance in estimating the effectiveness of interior doors as barriers to smoke flow and in the design of smoke control systems where stair and elevator. The smoke leakage control of.
