Why floor glass curtain wall needn't railing

First, laminated floor glass curtain wall can be set without railings 

Single floor glass (float glass, semi-tempered glass and tempered glass) will be flying after impact and broken, so that someone indoor have the risk of falling to the outside. 

Floor glass curtain wall set the anti-collision device is to prevent the danger.Laminated glass is not flying glass, although the impact can break the glass, but nothing can't cross the laminated glass plate.Glass curtain wall with laminated glass, eliminates the risk of people indoor through the glass fell downstairs, so laminated glass curtain wall don't set the anticollision railing. 


Second,most of point supporting curtain wall and cable net curtain wall needn't set up railings 

Architects use point supported glass curtain wall, especially with cable net glass curtain wall is try to improve transparent fully.

They don't want to add a bit of shade,even a thin railing, architects are often can't accept it.So point supported and cable net glass curtain wall or on the ground floor often keep set rail.

As long as used the safety laminated glass, we can create better conditions for the architectural function and art. 

Third, the outer laminated glass within inner single glass of insulated glass floor curtain wall needn't set up railings 

Many tall building glass curtain wall outside using laminated glass, inside used single glass (tempering or semi-tempering).

Though the inside single piece of glass maybe broken, but the outside glass is laminated glass, there is no people in danger of falling,so it needn't set up railings.Super high-rise building, curtain wall outside using laminated glass, inside used single glass, these projects are needn't railing.

Curtain wall beam, of course, the best adjustment to be layout at an altitude of about 900 mm, it will be more safe.
