Nolan Kienitz Posted November 7, 2013 Report Share Posted November 7, 2013 My $0.02 ... 1) Is it tempered glass? 2) Is spacing between balusters 4" or less? 3) They are simply ugly!! Quote Link to comment Share on other sites More sharing options...
Ben H Posted November 7, 2013 Author Report Share Posted November 7, 2013 My $0.02 ... 1) Is it tempered glass? 2) Is spacing between balusters 4" or less? 2) They are simply ugly!! 1) I think so 2)Yup 3)I agree.

If it wasn't site built, I'd be looking over the assembly for the ASTM number for the standard test method for glass railing systems.

Marc Posted November 7, 2013 Report Share Posted November 7, 2013 I might write up the lack of a newel post. Every glass baluster product I could find had a newel post on each end. That and what Nolan said. Marc Quote Link to comment Share on other sites More sharing options...
Jim Katen Posted November 7, 2013 Report Share Posted November 7, 2013 Can it support a 200# lateral load? Quote Link to comment Share on other sites More sharing options...
Jim Baird Posted November 7, 2013 Report Share Posted November 7, 2013 As I recall the code says guard must "resist" 200 lb applied laterally...question is what does "resist" mean? Quote Link to comment Share on other sites More sharing options...
Jim Katen Posted November 7, 2013 Report Share Posted November 7, 2013 As I recall the code says guard must "resist" 200 lb applied laterally...question is what does "resist" mean? I think that the generally accepted interpretation is that "resist" means "it doesn't break or become permanently deformed." However, if you're going to set up a test of such a rail, the test for most materials should use a safety factor of 2.5. Since a portion of the assembly in this case is glass, the safety factor would have to be increased to 4. So, effectively, the rail would have to resist a lateral load of 800# without breaking or permanently deforming. Quote Link to comment Share on other sites More sharing options...

I suspect that only a few, if any, currently installed residential rail assemblies would resist a 500 pound lateral load applied under laboratory test conditions.

Bill Kibbel Posted November 8, 2013 Report Share Posted November 8, 2013 A glass guard rail assembly has to pass a few tests per the ASTM standard, including supporting 334 pounds for 60 seconds. That's why the site-fabricated assembly would not be acceptable. Quote Link to comment Share on other sites More sharing options...

Jim Baird Posted November 9, 2013 Report Share Posted November 9, 2013 BTW those radial treads don't look like they would meet the six inch minimum on depth at the pointy end. Quote Link to comment Share on other sites More sharing options...
