What Is an All Glass Herculite Entrance
An all glass entrance uses thick tempered glass with patch fittings or top and bottom rails instead of a full aluminum frame, so the doorway reads as open glass from the street or the lobby. Herculite is the brand name that became shorthand for this type of frameless door, and we install all glass doors of this type from several hardware and glass suppliers.
Doors, sidelites and transoms are 1/2 inch or 3/4 inch tempered glass, ordered to the finished opening after the floor and door head are complete, then hung and adjusted by our own crews.
Single and Double Herculite Doors
Single doors for suite entrances and interior openings, pairs for lobbies and main entrances, with fixed frameless sidelites on one or both sides and a clear transom above. Sidelites join the doors glass-to-glass with a strike jamb, and everything sits in a header channel at the top and a channel at the floor.
Layouts include a door with sidelites, full glass vestibules, and interior all glass doors for suites and conference rooms. If the opening is on the exterior and needs weather sealing or an insulated unit, an aluminum storefront entrance is usually the better fit. Aluminum storefronts and framed glass systems are covered on their own page.
How All Glass Doors Hang: Closers, Pivots and Patch Fittings
There are two ways to hang an all glass door. A header at the top with a concealed closer carries the door on top and bottom rails, which is the usual choice for lobbies and main entrances. A floor closer set flush in the floor works with top and bottom patch fittings and keeps the head of the opening clear. Either way nothing is surface-mounted on the glass, and the patch fittings or rails carry the pivot and the lock with ladder pulls or push bars to match.
Where an entrance needs a push-plate or sensor, we install low-energy automatic operators on all glass doors as well.
Hardware finishes are brushed stainless, polished stainless, matte black and satin brass. We confirm closers, locks and handle style with you before ordering, and we set the pivots, hang the doors and adjust the closers so the doors swing and latch correctly.
All Glass Vestibules
A vestibule sets a second pair of glass doors behind the first, so conditioned air stays in the lobby when the outer doors open and the entrance still reads as clear glass from the sidewalk. We build both sets in the same 1/2 inch or 3/4 inch tempered glass with matching rails, pulls and finishes, so the two sets read as one piece of work.
The inner doors can carry their own locks and access control, which lets you hold a suite secure while the outer doors stay open through the business day.

I’ve been working with Modern Glass for over 15 years, and as a designer and developer, I can confidently say they have been one of my most trusted resources. Their workmanship, professionalism, and attention to detail have remained consistent throughout the years. Whether I’m working on a renovation, development project, or a custom design that requires a more refined glass solution, Modern Glass understands the importance of both function and aesthetics. In this industry, dependable vendors are everything. I value companies that communicate well, stand behind their work, and understand the level of quality my clients expect. Modern Glass has continued to deliver for me year after year. I highly recommend them to homeowners, designers, contractors, and developers looking for an experienced and reliable glass company.+4Posted on Google![]()
