Heating/Piping/Air Conditioning Engineering;Jan2006, Vol. 78 Issue 1, p62
The article presents several factors to consider in terms of selecting louver, a ventilation equipment that provides adequate rain-resistance and airflow characteristics. Some of the considerations in selecting and applying louvers are enumerated including rain resistance, pressure drop, sound and airflow shutoff. Moreover, common louver styles are also described in this article. These include standard louvers, wind-driven-rain-resistant louvers and operable and combination louvers.
