Frameless Glass Wall
Frameless Glass Wall
Frameless glass walls are large glass panels that slide on parallel tracks with no vertical frames between them. Direct WinDoors offers a frameless sliding glass wall system that is custom-made to your opening — patios, pools, restaurants, offices, sunrooms, and storefronts. Closed, the wall looks almost invisible. Open, the panels stack to one side or split to both.

Where Frameless Glass Walls Work
- Patios, terraces, balconies — open the wall fully when the weather's right; close it tight when it isn't.
- Pool enclosures and garden rooms — full view in, weatherproof closed.
- Restaurants, cafés, beach bars — open-air front with a glass wall that disappears.
- Retail storefronts and shops — full glass face that opens wide.
- Office partitions and conference rooms — frameless glass partitions divide space without cutting light.
- Sunrooms, winter gardens, pergolas, verandas.
- 90° corner installations — two sections meet at a right angle with no support column.
How the System Works
- Bottom-weighted design — panel weight rides on the bottom track, not hung from the ceiling. More stable, easier to operate.
- Unlimited opening width — no cap on panels or rails in a single opening.
- Self-adjusting top — 1 in (25 mm) clearance lets the system adapt to building movement over time.
- Stainless steel rollers — maintenance-free, rated up to 330 lb (150 kg) per panel.
- Drainage channel built into the bottom track — anodised aluminum with water evacuation openings.
- Minimum 3 bottom rails — every configuration starts with 3 rails; extensions add panel capacity.
Glass Options
- Standard thickness: 3/8 in (10 mm)
- Heavy-duty thickness: 1/2 in (12 mm)
- Glass type: tempered (12 mm requires structural adhesive plus activator at installation)
- Tinted glass: polymer interlayer
- Weight rule: glass averages 5.1 lb per sq ft (25 kg per m²). Total panel weight cannot exceed 330 lb (150 kg).
Configurations
All systems use a minimum of 3 bottom rails. Additional extensions add panel capacity.
- 2-panel side opening
- 3-panel side opening
- 4-panel central opening — panels split from center
- 4-panel side opening (3 rails + 1 extension)
- 5-panel side opening (3 rails + 2 extensions)
- 6-panel central opening
- 8-panel central opening (3 rails + 1 extension)
- 10-panel central opening (3 rails + 2 extensions)

Frequently Asked Questions
What are frameless glass walls?
Frameless glass walls are large glass panels that slide on parallel tracks with no vertical frames between them. The only aluminum visible is a thin strip at the top and bottom of each panel. Closed, the wall looks almost invisible. Open, panels stack to one side or split to both. Common in patios, pool houses, restaurants, sunrooms, and office partitions.
How much do frameless glass walls cost?
Cost depends on opening size, glass thickness (3/8 in vs 1/2 in), number of panels, configuration, finish, and hardware. Every system is custom-sized, so prices are quoted per project. Request a quote with your opening dimensions and we'll send a written estimate.
Can the panels open at 90° corners?
Yes. The system supports 90° corner installations with no support column at the corner. Two panel sections meet at a right angle and slide independently. Useful for indoor-outdoor patio openings and corner storefronts.
What's the maximum height?
Up to 10 ft 6 in (3,200 mm) with 3/8 in (10 mm) glass, or 10 ft 10 in (3,300 mm) with 1/2 in (12 mm) glass. Max panel weight is 330 lb (150 kg), max panel width is 4 ft 11 in (1,500 mm). Opening width is unlimited — panels run on a continuous bottom track.
How long is the lead time?
45 working days from order confirmation to shipment. Final dimensions are verified by on-site measurement before production starts.
Are these custom-sized?
Yes. Every system is custom-sized to your opening — panel dimensions, panel count, color, and hardware are all set per order. There are no off-the-shelf sizes.
What's the warranty?
