PSK sliding/ hopper balcony doors

The balcony door awning – slide PSK is a very interesting solution and alternative for traditional two-wings balconies. They do not open as normal wings, the movement is paralel to fixed wing (one wing fixed and second mobile). Such opening does not take place of the room and gives impression of more space in the hole. The maximal width of the whole construction amount to 4m (using ironmongery of Siegenia PSK). Problems with closing wings of big dimentions, particulary very high wings (there is need to tighten the upper part of wing to the frame) could be a disadvantage of this product. However, this is a very popular construction used by architects and investors.



Technical details

There are several variations of PSK balcony window who differ by type of glazing package applied. This means the safety glazing or P2 and P4 glazing packages, which is important for doors of glazing dimentions like 1600x 2200 mm. The window glazing bars can also be applied and the vernish colour can be applied according to Adpol pallet or on an individual Client`s order. One should remember that as the door is slid off, an aluminium threshold appears as a dividing doorstep which height is 70-: 80 mm .There is no possibility of making a low threshold doorstep with this type of balcony door
