I am involved with writing some specs for a project on a quick time frame (what else is new?) which involves a couple of systems that I have not had experience with (see next thread also). The first is a grid support system for stone panels. The project architect has Eclad Systems as a basis of design but wants to open it up. I am still learning about this system (MasterSpec does not have a master for this type of system), and I need to identify some alternative systems quickly. Through a web search - I see there is a system Gridwork. Does anyone have experience with these type of systems and know of systems similar to Eclad? ken hercenberg Senior Member Username: khercenberg Post Number: 381 Registered: 12-2006 Posted on Wednesday, November 28, 2012 - 12:06 pm:    Not familiar with either of them but I have used Carl Schilling stone anchoring system - http://www.carlschilling.com/internal/ISR.htm and was pretty impressed.

Some systems may dam water, create thermal bridges, or cause other issues that may detract from building performance. If removal of a single unit without dismantling the entire wall is important when a unit is damaged, make sure the system you choose can accommodate that requirement. Whether specifying around a proprietary system or just going with a performance spec, be aware of the nuances. You're doing more than just supporting the exterior skin. scott piper (Unregistered Guest) Unregistered guest Posted on Wednesday, November 28, 2012 - 02:35 pm:    I have a coupel of questions: is this intended to be a rainscreen install or a fully sealed system? Will these be full depth stone panels or will they be thin stone epoxied on a backing? Stone Panels, Inc. out of Texas has a mounting system that looks similar to the Eclad system and the "Ultra-thin" Stone Panels reduce the weight considerably. I actually did the AJ Smith Bank building shown on their website under financial projects over 15 years ago and it is holding up very well. The original building was cement stucco over steel studs and it leaked like crazy (insufficient expansion built into the system). The Stone Panels went up, all seams were caulked and it has not leaked since. the Stone Panels are not cheap but it is real stone with a multitude of stone options. The adhesion to the honeycomb backing has never been an issue that I have heard. In our area the install was actually carpenter work and not stone mason so it saved some money, trade wise anyway. There is a considerable lead time issue and in the past Stone Panels has missed delivery dates so if this is time sensitive then that could be an issue. Good Luck.
