Quick answer: Restaurant dividers are typically 3/8-inch or 1/2-inch tempered glass, 42–60 inches tall for booth dividers and full-height for room partitions. ADA requires a 36-inch clear aisle and a cane-detectable envelope between 27 and 80 inches above the floor. Food-safe means non-porous, sanitizer-resistant — plain tempered glass qualifies natively. Patio enclosures use folding or sliding tempered walls at $250–$500 per square foot installed and convert outdoor seating to year-round revenue. Permitting, occupancy and egress all change when you enclose a patio, so the glass package is only one piece of the project.
If you're scoping a divider package on a fit-out, start with booth and table dividers. If you're enclosing an outdoor patio, jump to patio enclosures. For the broader picture on commercial work, see the commercial storefronts and offices pillar guide.
Booth and table dividers
Booth and table dividers are the most common restaurant glass piece we fabricate. They went from a niche request to a standard menu item between 2020 and 2022, and most NJ restaurants we work with now keep dividers in some form — sometimes as full booth-back glass tops, sometimes as low table screens, sometimes as standing partitions between two- and four-tops in open dining rooms.
The standard fabrication is 3/8-inch tempered with flat-polished or pencil-polished edges, mounted in stainless or brass stand-offs, brushed-aluminum channel, or upholstered booth-back caps. Heights are usually 42, 48, 54 or 60 inches above the finished floor — 42 for counter-height privacy and ADA-friendly sightlines, 60 for full seated privacy between booths.
Mounting options
- Stand-off mounts — stainless or brass pins drilled through the glass, anchored to a partition wall or booth back. Clean modern look, easy to clean around, $80–$200 per stand-off installed.
- Channel mounts — aluminum U-channel set into the booth back or floor, glass dropped in and shimmed. Sturdier for tall dividers, hides the bottom edge. $40–$120 per linear foot.
- Upholstered booth caps — glass top dropped into a slot in the upholstered booth back, no visible hardware. The most refined look, common in upscale and steakhouse interiors.
- Free-standing weighted bases — for tables that aren't fixed to the floor or for temporary layouts. Less common since 2023 but still spec'd in flex-use private-event spaces.
For multi-restaurant rollouts and franchise build-outs, we standardize the glass package across locations and ship to each site with shop drawings approved by the franchise architect. See our contractor partners page for the multi-site workflow.
ADA, egress and the cane-detection envelope
Restaurant glass intersects with ADA more than most other commercial work because the dividers sit in active circulation paths and most restaurants have to maintain a percentage of accessible seating.
The three rules we design around on every restaurant divider project:
- 36-inch clear aisle on the accessible route. Booth dividers, table screens and standing partitions cannot intrude into the 36-inch aisle width.
- Cane-detection envelope from 27 to 80 inches above the floor. Anything that cantilevers more than 4 inches into the circulation path within that vertical range has to either extend down to within 27 inches of the floor (so a cane sweep catches it) or be flagged with a contrasting strip.
- Accessible seating count. The number of accessible booths and tables can't drop below the required percentage when dividers are installed. Wheelchair-accessible booths typically need the divider on the booth-back only, not on the open aisle side.
Most issues we catch on restaurant divider projects are dividers that hang off a booth end into the aisle within the cane envelope. The fix is usually a re-mount lower or a small extension panel down to within 27 inches of the floor.
Food-safe finishes and cleaning
Plain tempered glass is one of the most food-safe surfaces a restaurant can use — non-porous, won't absorb odors, doesn't harbor bacteria in the way that fabric, wood and porous stone can. NJ health-department inspectors are familiar with clear tempered glass dividers and partitions and rarely flag them as long as the edges are finished, the hardware is corrosion-resistant, and the panels are accessible for cleaning.
Three finishes need extra attention on the food-safe front:
| Finish | Food-safe rating | Cleaning notes |
|---|---|---|
| Clear tempered (no coating) | Excellent — natively food-safe | Any commercial glass cleaner, hot water, dilute bleach. No restrictions. |
| Frosted (acid-etched or sandblasted) | Very good — surface is still non-porous | The matte surface shows fingerprints less but holds onto oils slightly more. Cleans the same way as clear glass. |
| Back-painted (color on the back face) | Excellent on the un-painted side | Front face cleans normally. The painted back face should never be touched by sanitizer — paint side typically faces a wall or upholstered back. |
| Printed graphics (ceramic frit or digital print) | Good — printed surface is cured and durable | Avoid abrasives and ammonia on the printed face. Most chains spec ceramic frit specifically because it survives commercial cleaning chemistry. |
| Decorative laminates and films | Variable — depends on the film | Films used in dining areas need to be commercial-grade and sealed at the edges. Cheap residential films peel and harbor moisture. |
Our recommendation for any restaurant divider that will see direct diner contact is plain tempered with polished edges and stainless or brass hardware. It's the most durable, the easiest to maintain, and the most timeless aesthetically.
Tip: If the restaurant has open kitchen pass-through windows, treat them as commercial glazing with the same tempered-safety-glass requirement. Pass-through windows with stainless ledges and a 1/2-inch tempered panel run $600–$1,500 each depending on size and lift configuration.
Outdoor patio enclosures
Enclosing an outdoor patio with glass converts seasonal seating into year-round revenue. For most NJ restaurants, a 400-square-foot patio that's usable only April through October becomes a 12-month dining room with the right enclosure system — and the incremental revenue typically covers the build-out in 18 to 36 months.
There are three glass-wall systems we install on restaurant patios:
Folding accordion walls
Panels are hinged together and fold concertina-style to one or both ends. Best for narrow patios and where one end has a deep pocket to stack panels into. Tempered or laminated glass in slim aluminum framing, top-hung or bottom-rolling track. $250–$450 per square foot installed.
Sliding pocket walls
Panels slide along a top track and stack to one or both sides into a pocket. Best for wider patios with a side wall to disappear the panels into. Cleaner sightlines than folding systems when closed. $300–$500 per square foot installed.
Frameless slide-and-pivot walls
Panels slide individually along a single track, then pivot 90 degrees to stack parallel to the wall — the most open look when fully retracted. Best for high-end restaurants with the budget for slim, hardware-driven detail. $400–$650 per square foot installed.
Permitting and code on patio enclosures
Enclosing a patio is more than a glass project — it changes the restaurant's building envelope, occupancy calculation and often its egress configuration. The glass package usually represents 40–60% of the total enclosure budget; the rest goes to roof or canopy work, HVAC extension, electrical, code-required egress upgrades and architectural drawings.
Three code items always come up:
- Occupant load. Enclosed patio space adds to the restaurant's conditioned floor area, which can push the occupant load over a threshold that triggers additional egress, ADA upgrades, or a sprinkler requirement.
- Egress paths. The patio enclosure typically becomes an interior space, so the path from any seat to a code-compliant exit has to be re-mapped through the new walls.
- Mechanical and energy code. A heated and cooled enclosure has to meet the NJ energy code on the new glazing — usually insulated low-E in the fixed framing, and tempered (single or insulated) in the operable panels.
We work with the GC and the restaurant's architect on patio enclosure projects because the glass system has to coordinate with the canopy, the roof drainage, the new HVAC drops and any code-driven structural reinforcement. For trade pricing and the rollout workflow, see contractor partners.
Retractable acoustic partitions for private dining
Private dining rooms often need a partition that can open the room for a 40-person event one night and close it for a 12-person intimate dinner the next. Retractable acoustic glass partitions are the cleanest solution we install for that use case.
The system is a series of tempered or laminated glass panels suspended from a ceiling track. The panels roll out manually or with a motorized assist, lock together with edge gaskets, and provide 30–45 dB of sound attenuation when closed — enough to keep a private-event speaker from broadcasting into the main dining room. $400–$800 per square foot installed including the track, gaskets and any structural ceiling reinforcement.
Acoustic glass partitions are the only operable system we install where the spec really matters — single-pane 3/8-inch tempered gives 25–28 dB, while laminated dual-pane acoustic glass can hit 40–45 dB. The acoustic upgrade adds about 30–50% to the panel cost but is usually worth it for a private-dining application.
Bar-top and counter glass
Beyond dividers and partitions, restaurants also commission a steady volume of bar-top glass, server-station glass and counter inserts. Standard specs:
- Bar-tops — 1/2-inch tempered, flat-polished edges, often with a pencil or ogee finish on the diner-facing edge. Sized to the bar with a 1-inch overhang on the diner side. $80–$200 per square foot.
- Counter inserts — 3/8-inch or 1/2-inch tempered set into a routed recess in a wood or stone counter, sealed with food-safe silicone. Used to protect printed menus, drink-list cards or display goods. $60–$150 per square foot.
- Server-station glass — back-painted tempered behind expo or pickup stations to make the wall splash- and grease-resistant. $40–$90 per square foot installed.

Lead times for restaurant projects
Most restaurant openings have a hard date — soft opening, friends-and-family, lease commencement — that the glass package has to hit. Typical lead times from approved shop drawings to delivery:
- Booth and table dividers — 7–14 business days for clear tempered with polished edges. Add 1 week for custom edge profiles or finishes.
- Full-height room partitions — 2–4 weeks for tempered in stock channel and stand-off hardware. 4–6 weeks for laminated or custom-color frames.
- Folding or sliding patio walls — 6–10 weeks from approved drawings. The hardware sets the lead time, not the glass.
- Retractable acoustic partitions — 8–12 weeks. Custom acoustic glass takes time to fabricate.
- Bar-tops, counter inserts, server-station glass — 1–2 weeks for templated and fabricated to size.
For a fast pre-opening turnaround, we recommend sending the floor plan and divider locations to us as soon as the booth layout is locked — even before final finishes are picked. We can hold a fabrication slot and confirm edge details and hardware later.
Putting it together
Restaurant glass is the intersection of code, design and operations. Tempered safety glass is required on nearly every panel, ADA dictates aisle and envelope clearance, the health department wants non-porous surfaces, and the restaurateur wants something that looks good and survives a 16-hour service day for a decade. The right spec — 3/8 or 1/2-inch tempered with polished edges, food-safe hardware, sized to the ADA envelope — covers all four masters.
Send the floor plan, a sentence on the scope, and your target opening date. We'll come back with a written line-item quote, shop drawings, and a lead time the GC can build into the schedule.
