Motorized Guillotine Glass: Technical Specifications
Guillotine Glass System
Guillotine Glass is the premium alternative to traditional folding doors. These vertical sliding systems provide unblocked panoramic views while offering superior thermal and acoustic insulation.
The Operating Principle
The system consists of three or more glass panels that slide vertically.
- Balustrade Mode: When partially opened, the bottom panels remain as a safe glass railing (balustrade), while the top panels are tucked away.
- Full Seal: In the closed position, EPDM gaskets ensure the system is air-tight and water-resistant.
Technical Performance
| Component | Standard | Insight |
|---|
| Glass Type | 8mm or 10mm Tempered / 4+12+4 Insulated | Safety first with thermal efficiency |
| Motor | Somfy / Becker High-Torque | Smooth, synchronized vertical movement |
| Safety | Anti-Pinch Sensors | Essential for public restaurant spaces |
| Frame | Electrostatic Powder Coating | Any RAL color for brand matching |
Why Guillotine Glass?
Unlike horizontal sliding doors, Guillotine Glass does not require floor tracks that guests can trip over. It is the preferred choice for high-end hotel balconies and seaside restaurant fronts where wind protection and views are equally important.

Frequently Asked Questions
What is a guillotine glass system and how does it work?
A guillotine glass system (also called frameless sliding glass or lift-and-slide glass) consists of large glass panels that slide vertically up into a concealed housing above, completely opening the facade. Unlike folding or sliding systems, the glass disappears entirely when open, creating a seamless indoor-outdoor connection with no visible frame or panel stack.
What glass specifications are used in commercial guillotine systems?
Commercial guillotine systems use laminated safety glass (minimum 8.8mm: 4mm + 0.76mm PVB + 4mm) or tempered glass (minimum 10mm). For thermal insulation, double-glazed units (IGU) with low-E coating are used. Glass panels typically range from 1.2m to 3.5m width and up to 4m height per panel.
What wind and weather resistance do guillotine glass systems provide?
High-quality guillotine systems achieve wind resistance class 4 (EN 12210) and water tightness class 7A (EN 12208). The vertical sliding mechanism with perimeter seals provides better weather resistance than horizontal sliding systems. Motorized versions include wind sensors for automatic closure at preset wind speeds.
What is the typical cost and installation time for a commercial guillotine glass system?
Commercial guillotine glass systems cost €800–2,500/m² depending on glass specification, motorization, and structural requirements. Installation for a 50m² terrace enclosure typically takes 3–5 days. Structural assessment of the supporting wall/ceiling is required before installation to ensure it can carry the glass weight (typically 25–40 kg/m²).
