CleanCote Guardian is a composite panel for interior use made by laminating an aluminum skin to a substrate of type-x exterior grade gypsum board. This system is designed for use as interior cladding on walls in cleanroom type applications. However, Guardian is ideal for other applications where an easily maintained surface and a durable panel are the primary concerns. Guardian is installed using moldings with a nearly flat profile to reduce the possibility of dust accumulation. CleanCote Guardian offers a non-progressive attachment system utilizing two piece (plastic receiver and an aluminum cover) extruded moldings. First, the receiver is fastened to the studs and then covered with the edge of the panel. The panels are then mechanically fastened to the studs around the perimeter and adhered in the field of the panel using construction adhesive. After an approved sealant is applied, the joint is completed using aluminum snap-on covers.
