Louvers Similar to Lite Kits, Louvers are installed into the door body with the purposes of allowing light to pass through. However, due to the evenly spaced blades of the Louvers, visibility is not a function of the project. However, air flow between one side of the door to the other is an added function of the Louver over the Lite Kit. National Guard Products offers optional powder coating to customers with their louver purchases. The underlying LCA considers the impacts of powder coating. Unlike Lite Kits, glass installation is not applicable to Louvers. Louvers can be ordered in Cold Rolled Steel, Galvanized Steel or Aluminum. This LCA considers a hypothetical product made up of an average of those three material types. Reported products are an average product from a single manufacturing site. All products are produced at the National Guard Products factory at 4985 East Raines Rd | Memphis, TN 38118.
