Curtain wall systems are complex products, designed and built as unique solution, adapted for each building.
Curtain wall is very useful in protection of buildings from aggressive environmental factors, ensuring the thermal and acoustic insulation necessary for working or living rooms.
Advantages of curtain wall are multiple and provide thermal and acoustic insulation, light weight, availability regarding color, resistance to environmental factors, adaptation to any type of building, flexibility to building deformations due to vibration, earthquakes etc.
There are several types of curtain walls:
- classic – profiles cover visibly the glass both vertically and horizontally
- semi-structural – only an aluminum perimeter, which strengthens the assemble, is visible
- structural – only glass is visible, attached to the aluminum profiles through sealing.
Classic curtain wall
Profiles of this system cover the glass visibly, both vertically and horizontally, in a variety of combinations adaptable to any type of construction.
Inside the classic curtain wall simple opening, double opening or tilting inward and outward opening mobile windows can be fitted.
Structural curtain wall
Profiles are only visible on the inside, while the glass and seals are visible outside (gaskets EPDM or narrow lines of structural silicone resistant to UV) between sheets of glass, which may have thicknesses between 6 and 32 mm. Only openings into the building’s exterior can be achieved.
Semi-structural curtain wall
For semi-structural curtain wall only an aluminum is visible.
Semi-structural curtain wall is available in two forms:
- linear semi-structural curtain wall
Profiles are visible inside. On the outside, the profile is visible only in one direction (horizontal or vertical) and along the other direction is visible a black line (UV-resistant silicone), which gives the system a continuous mesh of glass on a certain direction.
One can use glass with thickness between 6 and 40 mm and the sealing is based on EPDM gaskets.
Openings can be made only to the exterior of the building.
- semi-structural curtain wall with frame
Profiles are visible inside. On the outside is visible only a narrow shape of glass and the windows for exterior are identical to their counterparts inside and give them an ongoing look when the window is shut.
One can use glass thickness up to 28 mm. Tightness is ensured by three rows of EPDM gaskets and a drainage system for any accumulation of water.
Profiles are available in all RAL colors and can be different colors for interior or exterior.
Today, modern facades are made of glass and aluminum. On functional, aesthetic and financial reasons the architects promoted boxes facades of composite aluminum bond type.
Bond is a composite panel made of two outer layers of aluminum with standard thickness of 0.5 mm connected by a high density polyethylene core, thickness of 3, 4 or 6 mm. The material is rigid, lightweighted and durable.
The finished product – the case – is obtained by processing three-dimensional bond sheets, sandwich shape providing vibration damping effect and high resistance to bending under the pressure of a strong wind. The visible part is covered by a multilayer painting, which guarantees reliability.
