Something that won't delaminate? Doing a small house project, and I would like to insulate the stem wall from footing on up. The wall finish will be an EIFS.

It's an interesting architectural topic, I always find it lacking when an exposed stem wall is below an attractive finish. Just wanted to reach out to the pros... Here's a consumer site that has some potential options:: http://www.greenbuildingadvisor.com/blogs/dept/qa-spotlight/how-finish-exterior-foundation-insulation Trevor Pan http://www.trevorpan.com Mark Gilligan SE, Senior Member Username: mark_gilligan Post Number: 754 Registered: 10-2007 Posted on Sunday, July 12, 2015 - 08:50 pm:    Before offsetting stud wall from face of concrete consult with the structural engineer. He may want to change a 2x4 wall to a 2x6 wall. anon (Unregistered Guest) Unregistered guest Posted on Monday, July 13, 2015 - 01:21 pm:    we spec this product for this condition: T Clear "Wallguard" - it is a mortar-faced XPS board, T&G with a clip attachment system. Architects are OK with it because it looks like concrete.

Back in the late 70's during the Carter era energy crisis, Dow Chemical introduced concrete faced XPS. It was first designed for the DYIer to insulate the exterior face of the homes foundation wall and provide UV protection for the above grade portion. It came with complete with mechanical fastener accessories. Concrete faced XPS soon migrated to the roof for protected membrane roofing (PMR) assemblies under the brand name of ROOFMATE CT. Very popular in heating climates 6, 7, and 8 (snow country). Very popular in my native land of Canada. Very handy for insulation the backs of roof parapets, exterior walls terminating at the roof deck. Over time Dow handed over this product to T-Clear Corporation and became known as LightGuard. Go to http://www.tclear.com/products/protected-membrane-roof/lightguard/ for information Trevor, please e-mail me at wayne.yancey@callison.com and I will compile my information on the uses of concrete faced XPS along with sample details showing end uses. Glad to help where I can.

Roof maintenance was reduced to an occasional visit to the roof to remove the trees that wanted to grow between the insulation panels. Styro Industries (www.styro.net/) has something similar, but it seems more of a residential product than T-Clear.

Another shameless plug. T-Clear continues (when last I looked) to furnish CFI wall panels. Interesting side bar. A very recent project for Shaw Communications in Canada used CFI. Someone higher up the design-food chain decided the clean joints were unsightly and required the entire CFI surface by parged to hide the joints. Stupid is as stupid does. If anyone out there wants more information, please e-mail me at wayne.yancey@callison.com. I am happy to spread the gospel of CFI.

I wonder how much they cost new.
