<p class="MsoNormal"><span style="color:#1F497D"> I have used both. The aluminum panels are clean through the core but have a couple of cons; if you mount bulkhead fittings through them, you cannot torque the locknuts enough to prevent rotating when making
up a fitting, this can be worked around with either using bulkhead retainers or asking a workmate to back up the fitting with a wrench. Mounting hardware for monitors and other hardware can be challenging if the base has only a small footprint but this can
be dealt with by backing up the mount with larger plates of aluminum. I’m pretty sure that the Neslo system can be used in a class 100 which makes it OK for a class 1000. The cost is less but you must be cautious when cutting or drilling. I use cordless cutting
tools and mist the work with water while cutting it to reduce particle generation then seal the edges of the cuts with cyanoacrylate glue. The melamine finish is very durable.<o:p></o:p></span></p>

<p class="MsoNormal">I am involved in choosing a wall system for a new Class 1000 space, in my Class 100 space we used Portafab Aluminum Honeycomb panels hung from a unistrut grid. The designer wants us to use Neslo wall panel system, it is high density fiber
board with a Melamine finish hung on steel studs. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Any thoughts, I am leaning towards the Aluminum Honeycomb panels.<o:p></o:p></p>
