The Fischer system is an open joint rainscreen system which can accommodate up to six inches of exterior insulation providing the client with a thermally efficient façade. The Fischer system is ideal for a running bond random pattern as pictured below as well as a stacked bond. It also allows for creativity in design where you can use a ¾" stone alongside an 1 ¼" stone. Since the undercut drilling technology works with a remaining wall thickness, it guarantees a perfectly aligned profile.
