We used our Series 400 rainscreen panel system for this project, which is a rear ventilated rainscreen system that also provides a ½” wide x 1″ deep reveal between adjacent panels. This system is the proven solution to exterior and interior panel needs when visible caulk joints are not desired. Pockets within the continuous perimeter extrusions receive reveal strips that fill the ½” gap between the panels. This reveal strip can be supplied in matching or contrasting colors giving the Series 400 systems a clearly defined joint line between the panels. The product was 4mm FR core Reynobond in bright silver metallic.
