What is the difference between single and double bypass sliding glass doors?

A single sliding panel moves along one track to stack in front of a fixed panel or into a wall pocket. Double bypass uses two independent tracks — each panel slides in the opposite direction, meeting in the center when closed. This allows a much larger opening to be fully covered without a fixed panel eating into your glass area.

Do WiseGlass NY sliding doors require a floor track?

Our standard system is top-hung — the glass panels hang from a ceiling-mounted aluminum track, with only a slim floor guide (not a track) to prevent lateral swing. This keeps your floor nearly uninterrupted. A recessed floor pocket option is also available for a completely flush finish.

How does the soft-close mechanism work on sliding glass doors?

Each panel carrier includes a hydraulic soft-close damper that engages in the last 4–6 inches of travel. The panel decelerates smoothly and closes with a whisper-quiet click — no slamming, no bounce-back. The mechanism is concealed within the top track housing and requires no maintenance.

What is the maximum width of a sliding glass partition?

Individual panels can span up to 60" wide and 144" (12') tall. For wider openings, we use multi-panel bypass systems — three or four panels on two or three tracks — allowing openings of 20 feet or more. Contact us to discuss your specific opening.

Can sliding glass doors be installed without visible wall studs to anchor the track?

Yes. Our header assembly spans between two structural points and can be fully concealed inside a drywall soffit. We work with your contractor or GC to plan the rough opening and header before walls close up. Retrofit installations into finished spaces are also possible in most cases.

The Sliding System

Open a room.
Define a space.
Close it again.

A sliding glass partition does what walls cannot — it adapts. Open for flow, closed for privacy, always beautiful. Top-hung from a concealed aluminum track, our panels glide on precision-engineered carriers and close with whisper-quiet soft-close dampers.

Top-Hung.
Barely There.

Our panels hang entirely from the ceiling track, touching the floor only with a slim guide pin. No continuous floor groove. No threshold strip. The floor stays smooth and uninterrupted beneath the glass.

Soft-Close,
Always Standard.

Every WiseGlass NY sliding system ships with hydraulic soft-close carriers as standard. The panel decelerates in the final 5 inches and closes with a quiet click. No slamming, no bouncing, no wear on the frame over time.

Up to 20 Feet
of Opening.

Multi-panel bypass systems — two, three, or four panels on two or three tracks — allow us to cover openings from a standard doorway to a full 20-foot room divider. Each panel is custom-fabricated to your exact opening.

Common Questions

What you need to know.

What is the difference between single and double bypass sliding glass doors?: A single sliding panel moves along one track to stack beside a fixed panel or into a wall pocket. Double bypass uses two independent tracks — each panel slides in the opposite direction, meeting in the center when closed. This allows a much larger opening to be fully covered with no fixed panel consuming glass area.
Do WiseGlass NY sliding doors require a floor track?: No floor track. Our system is top-hung — panels hang from a ceiling-mounted aluminum track. A slim guide pin set into the floor prevents lateral swing, but there is no groove, channel, or threshold strip. The floor remains clean and uninterrupted beneath the glass.
How does the soft-close mechanism work?: Each panel carrier includes a hydraulic soft-close damper that engages in the last 4–6 inches of travel. The panel decelerates smoothly to a quiet, controlled close. The mechanism is concealed inside the track and requires no maintenance or adjustment over time.
What is the maximum size of a sliding glass partition?: Individual panels can span up to 60″ wide and 12′ tall. For wider openings, multi-panel bypass systems on two or three tracks allow coverage of 15–20+ foot openings. Contact us with your opening dimensions for a custom solution.
Can the sliding track be installed without visible ceiling structure?: Yes. Our header assembly can be fully concealed inside a drywall soffit or existing ceiling finish. We coordinate with your contractor before walls close up. Retrofit installations into finished ceilings are also possible in most cases with minimal disruption.

How It Works

From consultation
to installed.

Free On-Site Consultation

We visit your space and measure the rough opening. We assess ceiling structure, confirm header anchor points, and walk you through every system option in person.

System Design & Selection

Single or double bypass, soft-close or barn-style, glass type, grid pattern, frame finish, handle profile — every decision made with drawings and samples in hand.

Custom Fabrication

Panels, track, carriers, and hardware are fabricated to your exact dimensions. No stock sizing adapted to fit. Every component purpose-built and factory-tested before shipping.

Professional Installation

Our own team installs the track, hangs every panel, adjusts the soft-close carriers, and sets the floor guides. We don't leave until every panel glides perfectly.

Space, reimagined with a single gesture.
