Glass doors are a favourite in offices, showrooms, cafes, and modern storefronts — they are bright, welcoming, and make a space feel open. But securing them is a genuine puzzle, because a frameless glass door has no solid edge to hold a traditional mortise lock. The answer is a purpose-built glass door smart lock, and this guide from Covlor® explains all your options for both framed and frameless glass doors.
Why Glass Doors Need a Special Lock
A conventional smart lock needs to sit inside the thickness of a door, held by a mortise pocket. Frameless tempered-glass doors have no such cavity, and you cannot simply drill into tempered glass without shattering it. Instead, glass doors use electronic locks specifically engineered for them — either mounted on the surrounding frame or clamped to the glass with protective gaskets. Choosing the correct type for your door is the most important decision you will make.
Framed vs Frameless Glass Doors
Framed Glass Doors
Many commercial glass doors have an aluminium or metal frame around the glass. These are the easier case: a slim electronic lock can be mounted on the frame rail much like a lock on a metal door, giving you keyless access while keeping the glass aesthetic. Framed doors often support a wider choice of models.
Frameless Glass Doors
Fully frameless doors — common in premium showrooms and offices — use a clamp-style electronic lock designed for tempered glass. The lock grips the glass edge with cushioned brackets and requires no drilling, preserving the seamless look while adding secure electronic entry. Always confirm the lock is rated for your exact glass thickness.
Best Access Methods for Glass Doors
Because glass doors are usually commercial, the ideal access methods reflect a workplace setting. RFID cards give staff fast, familiar entry that can be deactivated instantly if a card is lost. PIN codes suit temporary access for contractors or visitors. App control and entry logs let managers oversee access remotely and keep a clear record of who came and went — invaluable for shops, offices, and co-working spaces with high footfall.
Security Considerations for Commercial Glass Entrances
A glass entrance is often the public face of a business, so security matters as much as looks. Prioritise encrypted access, tamper alarms, and detailed entry logs, and pair the lock with toughened glass and a solid frame or clamp. For after-hours protection, scheduled access ensures the door only opens for authorised people at permitted times. These principles mirror our wider office lock guidance.
