It is my understanding that the brand name "Herculite" is no longer manufactured as an all glass entrance. Can anyone confirm/deny?
Thanks!

"Herculite" was the PPG trademarked name for their fully tempered all-glass entrances. A search of the PPG website does not turn-up Herculite.

However there are various other manufacturers that fabricate fully tempered all-glass entrances. Actually, we more often than not specify all-glass entrances generically (without reference to manufacturers), specifying the glass by reference to ASTM, top and bottom rails or patch plates by material and cladding (eg stainless steel or bronze), and scheduling of hardware, with drawings showing the configuration of the rails/patch plates. We name a specific product and manufacturer only when there is a specific product that the architect wants to use as a basis of design (for example, using Blumcraft's exit devices).

Thanks Dave. I asked because my clients continuously call out "Herculite" on their plans and I have been preaching that they no longer exist, it's a trade name, use "all glass entrance" etc. I just though I would double check to make sure my information is correct. Thanks! PS: Your drawings show the configurations of rails/patches? Wow!

Robin:

And I bet that they still use the archaic term "galvanized iron" or "g.i." when referring to galvanized sheet metal flashing.

Refer them to the National CAD Standard, which incorporates the Uniform Drawing System and specifically UDS Module 05: Terms and Abbreviations.

See: www.nationalcadstandard.org

What do they call the stuff covering interior stud walls? gypsum board? gypsum wallboard? sheetrock? "GYP BD"? "GWB"?

Actually, some drawings I reviewed yesterday called for "Type M Gypsum Board". I guess it keeps my days interesting!

If I remember correctly, all glass entrance doors are not ADA compliant. The reason being the locking bottom rail. There is no way a person in a wheelchair or walker can lock/unlock the door. Able bodied people have to stoop over or get on their hands and knees to lock/unlock to door.

Depends on the locking hardware, Dave.

For vestibule doors that are push-pull only, it's not an issue. For locking, we often specify these doors with overhead electric deadbolts, operated by cardreader, pushbutton or infrared detectors. And Blumcraft exit devices for use with these doors have the cylinder on a projecting plate at about mid-door height.

To my mind, a bigger issue is the requirement in ICC/ANSI A117.1-1998, 404.2.10, which in effect requires 10" high bottom rail on doors, with certain exceptions. One of these exceptions is bottom rails for all-glass doors, if they are tapered 60 degrees at the top. However, ADA does not have such a requirement, though they have a recommendation for kickplates.

The brand name Herculite has not been used in quite some time but the use of the name persists (like kleenex). Masterspec gives the generic designation -- all glass doors. PPG is no longer in the entrance/storefront/door business.
