World-Leading Wine Cellar Doors & Hatches

The Ultimate Guide to Modern Cellar Doors: Engineering, Safety, and Design

As the world's leading manufacturer and direct supplier of wine cellar doors, Dio-Met has seen a revolution in how homeowners and developers access subterranean storage. Whether you are uncovering a historic vaulted cellar or installing a modern spiral system, the cellar door is no longer just a hatch—it is a piece of high-performance architectural machinery.

This guide explores the technical realities of structural glass floors and automated access, ensuring your project meets the highest standards of safety and style.

Choosing the Right Operation: Manual vs. Automated

The first decision in any cellar project is how you intend to interact with the space.

• Electric Motorized Hatches: These systems offer a "theatre-style" opening and are ideal for high-end residential projects.  Electric Wine Cellar Doors

• Manual Gas-Strut Operation: A cost-effective, assisted-lift solution that remains a popular choice for frequent access without the need for complex electrical wiring. Manual Glass Floor Hatches 

• Circular vs. Rectangular: While rectangular hatches are standard, circular electric doors—often used for spiral cellars—provide a striking architectural focal point. Fulwood Circular Motorized Project

Technical Expert Insight: Structural Integrity & Safety Standards

When you install a walk-on glass hatch, you are effectively installing a moving floor. This requires engineering that goes far beyond a simple frame and glass pane.

Structural Compliance: Under BS EN 1090, any structural steel product must legally carry UKCA certification. Installing non-certified units can lead to significant insurance and legal complications for homeowners.

Anti-Slip Glass Technology

A common concern for "cellar door" queries is the safety of walking on glass with wet feet or socks.

• PTV Ratings: We utilize glass treatments that achieve a Pendulum Test Value (PTV) of 68.

• Safety Threshold: Any value over 36 is considered a "low slip risk" in the UK; our 68 rating ensures exceptional grip without obscuring the view into the cellar. Glass Floor FAQs
