Frameless Glass Partitions for Offices

Glass divides a floor plan without giving up daylight, and a frameless system can be taken down and re-set far more easily than drywall when a tenant or layout changes. Panels are 1/2 inch tempered glass with polished edges, set in U-channel at the head and the floor with glass-to-glass joints, so the wall reads as one clean line of glass.

This page covers frameless interior glass. For aluminum-framed office partitions, framed vestibules or an exterior storefront, see our aluminum storefronts and framed glass systems page.

Planning an office fit-out or a new conference room?

Frameless Glass Office Doors and Hardware

Single and double frameless swing doors hang on top and bottom patch fittings, with ladder pulls and a lock in the patch fitting or rail. Top-hung sliding doors run on an exposed or concealed track where a swing door would block a corridor.

Two ways to close a frameless door: a 4 inch to 4-1/2 inch header with a concealed closer, which suits any opening including higher-traffic doors, or hydraulic patch fittings, covered below.

Finishes. Matte black, brushed stainless, polished stainless and satin brass. Locks are mechanical glass-door locks in the bottom or floor position, centre patch locks, or magnetic locks where a door is on access control. We furnish and install the hardware and leave the wiring accessible for your access-control professional to connect and commission.

Hydraulic Patch Fittings and Doors Without a Header

A hydraulic patch fitting puts the closer inside the bottom patch fitting of the door itself, not in a header above it and not in the floor. The opening can lose the header entirely, so the glass runs clean to the head and the door reads as part of the wall, with nothing cut into a finished slab.

We use them on private offices and conference rooms. For a main entry, a corridor door or anything on a busy floor we specify the 4 inch to 4-1/2 inch header with a concealed closer instead.

Glass and Privacy Options

Glass. 1/2 inch tempered clear glass is standard for partitions and doors, with 3/4 inch for certain applications. Low-iron extra-clear and laminated glass are available.

Privacy. A frosted band at seated eye level, a partial band or a full panel. Privacy film is applied to the surface of the glass and can be changed later. Acid-etched glass and acid-etched bands are a permanent finish in the glass itself, so they cannot peel or be removed.

Tell us which rooms need privacy and we will show you the options against your layout.

Smart Privacy Glass

Laminated powered glass that switches from clear to frosted, so a conference room or executive office goes private without blinds, film or a second door.

Custom Printed and Branded Glass

Logos, graphics, patterns, door signs and office identification printed permanently into the glass, with ceramic frit fused into the surface during tempering rather than applied on top.

How the Project Runs

PLANS OR SITE VISIT  →  QUOTE  →  FIELD VERIFICATION  →  GLASS & HARDWARE SELECTION  →  INSTALLATION

We quote from architectural plans, drawings, specifications and bid documents, or from a site visit. Once the job is awarded and framing, ceilings and flooring are in, we field verify every opening so the glass is made to the real dimensions. Glass and hardware are confirmed with you before ordering, and our own crews handle the installation, working around your hours in occupied offices.

We work with general contractors, architects, designers, property managers, building owners and commercial tenants across Loudoun, Fairfax, Arlington and Alexandria, Washington DC and the close-in Maryland suburbs. Builders and GCs can also see our information for contractors page. Looking for a glass wall or room divider in a home? See our residential glass walls and room dividers page.

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.
