I live on the 6th floor, the balcony is closed with general glass, insulating or tempered glass

Tempered it, 6 is about the same.

Requirements of national codes: In accordance with the GB50352-2005 "General Principles for the Design of Civil Buildings" and the GB50096-2003 "Code for Residential Design", balconies, verandahs, corridors, inner patios, outdoor stairs and other empty places should be provided with anti-collision railings and comply with the following provisions:

The airfront railing glass that does not bear the horizontal load should have a certain impact resistance, and tempered glass or tempered laminated glass must be selected, and its thickness should not be less than 12mm; When the height of the air is 5m and above, tempered laminated glass should be used. For indoor non-empty railing glass, tempered glass with a thickness of not less than 5mm or laminated glass with a thickness of not less than is not less than is available.

Of course, hollow, thermal insulation and sound insulation, the current buildings are all insulating glass.

It depends on how much money you have prepared.

Ordinary glass is OK, if you want to keep warm, insulating glass is better, laminated glass is recommended, the effect is very good. It's just expensive.

If it is not a floor-to-ceiling window, there is basically no difference between tempering and ordinary, after all, it is necessary to install an anti-theft net, and it does not rely on glass to prevent theft.

Do you understand the first floor?

If you don't understand, don't quote the standard blindly. Do you know what it means to be in the air?

The general standard thickness of the glass for aluminum alloy plastic steel windows is 5 mm. Both the greater and the smaller than this glass are special.

Of course, if you want to be fast, you can choose tempered glass. Because the strength of tempered glass is much greater than that of ordinary glass.

If you want to save energy, you can choose insulating glass. Insulating glass can play a role in sound and heat insulation.

The general standard insulating glass is also made of 5 mm glass.

Ordinary 5mm is fine.
