When architecture calls for seamless transitions between indoor and outdoor spaces, the PEAK Folding Glass Door SL 60e delivers an unparalleled combination of structural integrity, thermal performance, and effortless functionality. Engineered for projects where quality and aesthetics are non-negotiable, this system represents the pinnacle of modern door technology.
The SL 60e system offers exceptional flexibility to suit any architectural requirement. Available as either floor-mounted (standard) or top-hung configurations, the folding glass door can be ordered to open internally or externally, to the left and/or right—allowing complete freedom in layout design. Whether you're designing for a residential terrace, commercial showroom, or luxury villa, the system adapts seamlessly to your vision.

With a system profile thickness of just 59 mm and narrow frames (panel joint of 130 mm), the SL 60e achieves a clean, minimalist aesthetic without compromising structural stability. The innovative tongue-and-groove interlocking panel profile combined with robust corner joints featuring thermal insulation ensures long-term durability and energy efficiency.
For accessibility-conscious projects, a flush floor track without upstand is available, providing barrier-free access compliant with disabled access requirements.

The SL 60e is designed to perform under demanding conditions. The system has been rigorously tested to meet or exceed European standards:
| Test Parameter | Performance Level | Standard |
|---|---|---|
| Air Permeability | Class 4 | DIN EN 1026 / 12207 |
| Water Tightness | Class 7A | DIN EN 1027 / 12208 |
| Wind Load Resistance | Class B4 | DIN EN 12211 / 12210 |
| Long-term Functional Performance | Class 3 (20,000 operations) | DIN EN 1191 / 12400 |
| Burglar Resistance | RC2 / RC2N | DIN EN 1627:2011 |
| Secured by Design | Certified | PAS 24:2012, BS 6375-1 & 2:2009 |
Double wraparound seals provide superior protection against wind and rain, ensuring the door remains weathertight even in exposed locations.

Energy efficiency is at the core of the SL 60e design. The system achieves a U-value as low as 1.10 W/m²K (Uw ≥ 1.10) with standard double glazing. Solid multi-chamber profiles with foam core construction meet the latest energy conservation regulations (EnEV), helping reduce heating and cooling costs year-round.
Glazing options include:
Heat-insulating glass as standard: Ua = 1.1 W/m²K (k = 1.0) with 2 × 4 mm float glass
Triple glazing available for enhanced thermal performance
Glass thicknesses from 5 mm to 40 mm to suit diverse project requirements
The SL 60e is designed for effortless use. Long-lasting stainless steel runners and tracks ensure quiet, smooth operation throughout the door's lifespan. Key operational features include:
Safe Operation: A special catch secures the swing panel, ensuring the door can be carried along safely
Height Adjustment: Post-installation adjustment of approximately 6 mm accommodates building settlement
Width Adjustment: Hinges can be easily adjusted with a screwdriver for precise panel alignment
No Protruding Runners: Concealed fittings enable one-handed operation and a clean appearance
Lockable in Any Position: Flexible locking options for security and ventilation control
The integrated multipoint locking system works in conjunction with a comfortable door handle featuring catch bolt, lock, and profile cylinder to deliver high security. The espagnolettes with 24 mm throw lock panels securely into the top and bottom tracks, ensuring the door withstands gales while providing peace of mind.
Burglar resistance certification up to RC2 / RC2N is available, and the system meets Secured by Design standards—an essential consideration for projects requiring enhanced security specifications.
The SL 60e is part of a comprehensive window and door system. A complete window system is available to match the folding glass door, including:
Tilt and turn windows
Parallel slide and tilt windows
Fixed panels
This allows for cohesive design language across entire building facades.
To meet the unique requirements of each project, the SL 60e offers extensive customization:
| Feature | Options |
|---|---|
| Surface Finish | Powder coating to RAL or anodised aluminium to EURAS |
| Panel Sizes | Height up to 3,000 mm; weight up to 80 kg (special sizes available on request) |
| Glazing | Single, double, or triple glazing; various glass types and thicknesses |
| Configuration | Internal/external opening, left/right, floor-mounted or top-hung |
The SL 60e accommodates a wide range of project scales:
