Glass Door Guide: Tempered Safety Glass vs. Laminated Safety Glass & Design Tips for Your Home

Glass doors are more than just room dividers – they are a modern design element that brings light into dark hallways and visually enlarges rooms. But those facing the purchase decision often have many questions: Which glass is safe? What is the difference between a hinged and a sliding door? This guide tells you everything you need to know before buying.

1. Safety first: ESG vs. VSG

When buying a glass door, you will repeatedly encounter the terms ESG and VSG. But what do these abbreviations mean, and what do you really need?

• Tempered safety glass (ESG): This is the standard for most all-glass interior doors. The glass is thermally treated, making it extremely impact and shock resistant. Should it break, it shatters into small, blunt fragments that pose little risk of injury.
• Laminated safety glass (VSG): This consists of two panes of glass bonded together with a tear-resistant interlayer. If the glass breaks, the shards adhere to the interlayer (similar to a car windshield). Laminated safety glass is often recommended where increased safety is desired, for example, for families with small children.

2. The design: clear glass or frosted?

The visual appearance significantly influences the effect in the room. The main question here is: How much privacy do you need?

Clear glass (transparent)

Clear glass allows maximum light to pass through and visually connects spaces. It is ideal for:

• Living rooms that should appear open
• Dark hallways that require daylight from the adjacent rooms
• Offices to keep in touch

Frosted glass (milk glass)

Sandblasting or etching makes the surface opaque, but it remains translucent. Perfectly suited for:

• Bathrooms and guest toilets
• bedroom
• Rooms where clutter (e.g., pantry) is to be hidden

3. The opening: sliding door or revolving door?

Not every room has space for a classic door that swings into the room.

The classic revolving door: It is mounted in a frame and functions like a wooden door. It seals more tightly (better sound insulation) and is the standard solution for most renovations.

The sliding door: The modern problem solver. It runs in front of or inside the wall. Since it doesn't require any swing space, you save valuable room. Ideal for small apartments or narrow doorways.
