Home improvement: building a glass room

Project overview, choice of the materials

The below terrace is located in between two blocs of a multi-apartment building which is affecting its privacy. It was decided to transform it into a glass room. The owner, an interior designer, decided to glaze most of the area while leaving a little space all around as planters.
A low maintenance material is used for the frame (powder coated aluminum profile) and a triple layer tempered glass ensures the tightness of the roof while allowing the sunlight to pass through.
The glass room walls are made of a central fixed glass panel that provides the necessary rigidity and strength to the whole room with sliding glass doors all around equipped with mosquito nets.
A ready-made tiled-roof window has been purchased and integrated into the glass roof in order to evacuate the hot air that accumulates in there in hot weather and to provide a natural ventilation even when all sliding doors are closed (the window is still vented when closed).
The glass walls have been elevated on a brick wall for safety purpose i.e. not to let the glass reach the ground on one hand and for using the brick wall as a planter on the other hand.

The fixed glass in the middle of the left picture strengthens the whole glass window assembly.
Two sliding doors on each side of the fixed glass panel provide wide openings for ventilation and for taking care of the plants.
The brick wall planter is visible in both pictures.
​The aluminum frame is simply sitting on it, then sealed with a beige silicone compound.

Glass roof details

​Measurements were taken with a normal measuring tape, then Autocad was used to draw the frame and the roof panels. The CAD drawing was printed on paper in order to cut the roof supporting aluminum frames. and provided on a USB stick to the glass manufacturer who loaded the drawing directly in the glass cutting machine.
​
A wooden pitched roof window was integrated to the central frame above the fixed glass panel which also increases the overall rigidity of the glass window.
The window is held to the aluminum frame by the means of four screws on each side.
The accessory usually used all around this window to allow its installation in a tiled roof has been skipped.

The glass panels are bonded to the aluminum frames with crystal clear silicone, then 3mm thick flat aluminum blades were used to cover the silicone so it cannot be seen when an observer looks at the glass window from top.

A poly cotton curtain was fitted to the largest glass panel, the one that faces the neighbors and for obvious privacy purpose.
The curtain is a simple thick white fabric sewed all around though strengthening its edges and  fixing rings integrated on all 4 corners. The rings are held to the aluminum frame with hooks to keep it well stretched.
It can be easily removed and refitted for washing.
