Facades

1. Glass facades

We bring to your attention our offers on hung glass facades. There are various types of hung glass facades but principles of installation of all types are the same: glass packets are hung on a special aluminum or steel construction. Supporting structure consists of vertical (mullions) and horizontal (transom) profiles that are fitted with special brackets to the reinforced concrete elements of the building. The drainage system of these facades is more specific. The facades actually project out of the concrete shape of the building. The horizontal and the vertical elements play role of horizontal and vertical drain pipes. Thus, if water gets behind the glazing, it reaches the horizontal elements, from there it is channeled to the vertical elements and then down to the exterior of the building.

Glass facades differ as per the joint type between the glass packets:

 • Capped facades

The weight of glass packets is carried by the horizontals and thereby is transmitted to the verticals. Glass packets are fixed by using aluminum strips with pre-installed 50-60 mm rubber sealants.

The aluminium strips are screwed to the supporting structure and are usually covered with special decorative caps. Because of their relatively low cost and high security, capped facades are the most common type of glass hung facades.

 

 

 

 

Dry joint facades
 

Glass packets are fitted to the aluminum frames to form cassettes and then are mounted to the supporting structure. There are rubber sealants along the perimeter of the aluminum profiles of the cassettes that bar water penetration. There are two methods for installation of glass packets to aluminum frames. The first method is by the special geometry of the profiles that encase the glass packets, where the profiles remain visible along the perimeter of each glass packet. The other method is by "sticking" the glass packets on to the frames. This is carried out by a special two-component silicone. This system is with the lowest level of stability because it relies solely on silicone to hold glass packets. Of course silicone manufactures give a long warranty, but unfortunately do not explain what happens after warranty expires. Another drawback of this facade is that the rubber gaskets are not tightly stuck to the plane of the outer pane and therefore when dust and dirt pile up, cleaning it is quite difficult.

 

Silicone joint facades

When facades is on silicone joints, glass packets, as a rule, are produced either with a special spacer / as in "Schuco /, or with factory-installed special aluminium profile that incases the inner glass, thus forming a cavity in the area of the silicon filler. In the cavity are placed special elements which are screwed to the supporting horizontal and vertical profiles. These elements press the inner glass pane of the glass packet to the construction and the outer glass hangs from the front only due to a special two-component silicone. Joints between the glass packets are also filled with silicone. That process is applied by "Etem"and "Alumil".

2. Ventilated facades

This type of facade consists of steel, aluminum or wood structure and different types of finishes. Technologically it is implemented in the following sequence:

• installation of the brackets to hold construction
• installation of insulation - mineral or stone wool
• installation of waterproofing membrane
• installation of the substructure
• installation of panels

Panels could be of different materials: etalbond, stone, ceramics, fibre cement (eternit), wood etc. The interesting fact about these facades is that there is distance of 3-4 cm between the panel and the insulation. In winter, the air there is at least a few degrees warmer than outside air. Consequently, that warmer air circulates upwards and takes with itself the water vapor coming out of the building, thus keeping thermal insulation always dry. The most important quality of this type of facades is that they "breathe" and do not allow moisture to stay inside the building.
