Extreme-Woodlam™ (EWL) Panels used to Blast Strengthen a Conventional Pre-Engineered Metal Building (PEMB)

Our goal was to trengthen a conventional pre-engineered metal building design in western Texas for blast resistance using minor design modifications and the installation of our Patented Extreme-WoodLam™ (EWL) panels on the building exterior. Figure 1 and Figure 2 show 3D renderings of how the EWL panels can be incorporated with the building cladding. Figure 3 shows actual construction photos and final building installation will be published soon.

The Patented Extreme-WoodLam™ (EWL) panels were developed and fabricated at the plant and shipped to the construction site, along with installation instructions, labels and design certificate letter for the blast load rating.

The EWL panels proved easy, fast and cost-effective to integrate into the building cladding profile. The EWL panel system steel cladding panels are efficiently and quickly installed directly over surface of wall girts and roof purlins and doesn’t require the use of steel self-tapping bolts.  

The panels were fabricated to unique sizes to fit snuggly on the PEMB and the workability of the panels made connecting them to the building framing a breeze. In addition, the EWL panels improved the thermal insulation of the building exterior.

 Overall, the EWL panels provide a blast-resistant product with the workability and enhanced insulation properties of wood panels. Both properties make EWL panels an attractive blast-resistant solution for building modifications/retrofits and for buildings located in hot and cold weather environments.
