David,

This sounds like a variation of the EIFS crapola

Guys,

I am not a mason by any standard, but I have seen a system in play that seems closer to terra cotta than fiberglass. While doing an install in San Antonio a couple years back, I was forced to work nose to nose with a masonry crew who were installing lightweight masonry cornice and other decorative elements. The material was light weight concrete formed in rubber molds over an armature(?) of styrofoam. Very light and not bad looking. They were applied over what seemed to be EIFS attached with stainless brick ties and a lot of Sika bonding goo. Of course the look they were going for was Spanish colonial and sandstone so the method worked out pretty well for that app. This was at one of those awful discount mall developments and the same crew did a Palladium Theater in Classical style with a good result. I'm sure this is probably a pretty common thing, but I had not seen it before. I'm a traditional wood guy by choice.

fiberglass balustrades and parapets that have gone 20 years. fiberglass church parapet going on 12. a fiberglass cornice, more than 200 feet and 15 years old, the roof overhang in brackets of the Federal Bldg are fiberglass (3 years). several pinnacles that look fine.

I don't like fiberglass as part of the facade, only above the flashing or roof..

Given the foregoing, why not? Don't we think Mrs. Baptist Church Architect Of 1810 would have used fiberglass, had it been available to her? Assuming the life cycle costs of painting are great, is it fair to doom the Federal Building to the presumed expense of a tin cornice? Is it responsible stewardship to spend a lot more for a copper cornice simply because it will "get a nice patina" which 95% of people will not notice? Yeah, I don't like fiberglass either but ....
