Dominicans Are Screen Experts.
... Dominicans ... Maybe they think it stops the breeze?
Dominicans are always right...
"Many assumptions are made regarding rear screens on louvers. A very limited amount of industry testing has been done and the data is only relevant for new, clean screens. Dirty screens will eventually reduce the free area significantly.
In general, the free area of a louver is unaffected by a clean screen. AMCA (Air Movement and Control Association) tested and published results for the effect of screens on louver airflow and water penetration in their January 1994 Techspecs document. These tests demonstrated a slightly positive or negative effect on airflow through the louver (depending on the type of screen). Pressure loss increased 11% to 17%. Water performance improved 12% to 33%. But screens under airflow will eventually get embedded with dirt and grime, so most of the industry data is not relevant to real world application.
For small mesh screens (under " mesh) used at air intake locations, the buildup of dirt and grime can reduce the free area 10% to 90%. If left without maintenance, the screens will eventually block most of the airflow. If access to the screens is limited or maintenance is questionable, large mesh screen should be used."
... my Dominican girlfriend was watching TV with the screen opened near her. I told her to keep it closed. She said the breeze won't come through then. I went to the kitchen, filled up a large glass of cold water. I went on the patio off of the screen to the bedroom, closed the screen and threw the whole glass of water in her face through the screen.
Dominicans are always right...
Although you
threw the whole glass of water at her face, a good amount of it was reduced by the screen. :bunny:
She was not dumb.
