To be noted in design

Postless railing

DET 1: The concrete colons of the balcony must be placed so that they do not prevent the opening of the balcony glazing system. The gap between the vertical pillar and the slab must be at least 80mm, so that the top installed lower frame fits. Without cut outs the 225 wide handrail needs 205mm, and the 160mm handrail 155 mm, between the pillar and the railing. Should the slab be supported with steel pillars in a way that the wall side end is attached to the structure and the outer edge is pillar-supported, it might move vertically due to heat movement, form the area to be glazed into a parallelogram and cause problems with glazing functionalities. Especially in tall buildings the balcony structures must be designed as such that supporting will not be done from building frame, but that all balcony supports adapt to any heat transformations.

DET 2: The placing of the draining pipe must consider the opening of the balcony glazing. With balcony-specific drainage, a pipe is piercing the slab facade. In this part of the railing, a facade cover profile must be used on slab facade height, so that the profile can be pierced through the railing. A preferable method is to place the railing on top of the slab, so that the forementioned problem is avoided.

DET 3: The frame walls must be vertical and plain for functional and good looking junctions on both railings and balcony glazings. Profile panels, windowsills and big variations in the wall surface often need flashings to cover the interface. A 10-40mm gap is used between the frame wall and the railing. The railing is attached to wall structures, which also bear the loads. Installation points' distances to the edges are good to consider already in the design phase.

DET 4: Balcony glazings are supported from the upper profile. Therefore the fastening must be done into a stationary structure. Wood structures should be avoided. In upper building floors, it is advised to bring the balcony's ceiling slabs at least 100mm further than other balcony slabs. Upper slide rail can not be sunk into the structure, because while opening the glazing, there will be guide components coming out of the profile. Glazing width should be between 600...850mm.
