[labnetwork] cleanroom construction question

[Paul, Jack]

Hello Rick,
In a Class 1000 environment we would recommend against the use of the Neslo fiberboard / melamine panels.

If you are applying the panels to finish the surface of a metal stud and gyp board wall, then the ¼" honeycomb aluminum using H/J/Z trim shapes will provide the best results long term (durability, ability to de-mount in operating cleanroom to make major modifications, and the ability to make minor modifications within the cleanroom).

If you are building free-standing partitions within the cleanroom, then a ¼" aluminum honeycomb panel in an aluminum strut system is definitely the best way to go.  Plascore, Webb Core, Portafab, etc - there are several options available and for light to medium duty they are cost-effective.

Best of luck with the new Class 1000 facility.

Rich,
  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.
Hope this helps,
Steve

HI,

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.

Any thoughts, I am leaning towards the Aluminum Honeycomb panels.

Rick
