PalmSHIELD Engineering Summary for Horizontal Louvers

Important Performance Design Critera Outputs and Design Criteria for Louvered Screening

The PalmSHIELD product loves to be poked and prodded by engineers. This system has been assessed many times to meet specific engineering and application requirements. PalmSHIELD also recognizes that not all projects require this level of manufacturing. Even so, the end user is going to want a guarantee of the design and capability of the system. PalmSHIELD is now providing engineering summaries for their most common heights and styles based on the previous engineering performed. These engineering summaries not only provide some assurance of performance but basic designs specific to post layout, louver spacing, etc. These are provided in hope that this information will be helpful to customers to complete their job layouts quickly and efficiently.
