Builder's Best Wall BB 8 Louvered Flush Mount With Screen

The Builder's Best 110861 is an 8 inch louvered flush mount wall vent with a screen, providing an exterior termination for ventilation ductwork.

The flush mount configuration sits close to the wall surface rather than projecting from it, which suits installations where a protruding hood would be visually obtrusive or would conflict with adjacent features such as trim, downpipes, or siding details.

The screen is the specification detail that requires judgement. A screen keeps insects and small animals out of the duct, which is a genuine benefit on a ventilation termination that may sit idle for long periods. On any exhaust carrying lint, however, a screen becomes a lint trap: fibres catch on the mesh, build progressively, and restrict the duct until airflow falls to a fraction of its design value. Clothes dryer exhaust must never terminate through a screened vent for this reason, and kitchen exhaust carrying grease-laden air presents a related problem.

For bathroom, general ventilation, and equipment exhaust the screen is appropriate, provided it is inspected periodically.

Correct installation requires the vent to be sealed to the wall surface and integrated with the water resistive barrier and siding so water is shed over the flange rather than behind it.

Applications include residential and light commercial exterior wall ventilation terminations.
