Unitised Curtain Wall

The Unitised Curtain Wall system is a facade system for high-grade buildings. It consists of the fabrication of different components and materials into a whole panel spanning one or more storeys on the shop-floor itself, before it is transported to the construction site for installation/erection. With the integrated advantages of factory assembly, the use of standardised technology along with a highly shortened construction period, it has become the most popular facade system today.

FEATURES

  • The panels are assembled in the factory in standardised units, with a high degree of accuracy and precision.
  • It allows better and more effective control of the construction schedule.
  • Highly shortened building construction period, since panels can be installed simultaneously with construction of civil work.
  • Uses gaskets for sealing between units, allowing for inter-unit displacement due to thermal expansion as well as sway of the main structure (applicable to high-rise buildings).
  • Discards the necessity of on-site application of sealant, thus making installation independent of weather conditions.
  • Adopts a pressure equalisation principle along with an innovative drainage system, creating excellent resistance to water leakage and air penetration.

Semi Unitised Curtain Wall

A Semi-Unitised curtain wall requires installation of individual framing members to form the support grid for the glazing of the infill panels.

FEATURES

  • Ideal for glazing in patches.
  • High Quality of Curved and Sloped Glazing.
  • Allows easy installation of panels, without having to go in a particular sequence.

LARGE SCALE ELECTRIC HORIZONTAL TURNING SHADING SYSTEM

An aluminium shading system is applied using a fish abdomen like streamlined vane design that causes air dispersion and light refraction. An intelligent control system is used to adjust the whole vane’s angle to achieve adjustment of indoor lighting.

LARGE SCALE ELECTRIC VERTICAL TURNING SHADING SYSTEM

The use of vertical perforated metal sheets effectively prevents strong and direct light, only allowing the gentle introduction of natural light, especially suitable for east and west side elevations. It is connected to an intelligent control system that optimises the vane angle for shading.

LARGE FIXING SHADING SYSTEM

The shading panel is a permanent connection with the vane angle adjusted in different regions at the time of installation. It also provides an artistic appearance that is consistent with the glass curtain wall elevation. It is a simple structure, with easy installation and high security.

Bolted Glass Assemblies

This is a structural glass assembly consisting of a series of specially processed glass panes, bolted together at their corners by means of ‘spider fittings’ or ‘metal patch fittings’ along with silicone sealant at the pane-to-pane joints. The minimization of metal framing members creates an effect of transparency that forms a natural and artistic blend between the indoor space and the outdoor environment. Different methods can be used to support the dead-load of the system and to provide lateral stiffness against wind-loading. Depending on the method used, the system is sub-divided into:

FIN

The glass facade and glass fin is connected using stainless steel spiders. The top of the glass panels/fins are supported at the top, in order to withstand the dead-load of the system, either using bolts/welds (if steel) or anchor-fasteners (if concrete). Consecutive Glass fins are connected using bolted splice plates.

TENSION ROD SYSTEM

Tension Rod System: The composite structure is set up with the of ‘tension rods’ (stainless steel pipe structural members designed to always be in tension). The tension-rod structure withstands the exterior loading on the glass facade.

STEEL STRUCTURE SYSTEM

All the loading on the glass facade is transferred by means of stainless steel ‘spider fittings’ to a steel structure erected independently behind the facade.

CABLE SYSTEM

A system of geometric non-linearity is set-up with the use of pre-stressed tensile cables that withstand the exterior loading on the facade system. The vertical cable also withstands the dead-load of the system.

This system is further subdivided into Cable Truss Systems and Cable Net Systems.

  • Cable Net Systems: The structure is based on the principle of the tennis racket, using a single–layer plane cable net structure (horizontal and vertical pre-stressed tensile cables), thus producing rigidity to withstand the exterior load.
  • Cable Truss Systems: The structure uses a horizontal plane cable truss to withstand the exterior wind-load. The vertical cable plays a stabilizing role and takes the dead-load of the glass facade.

Double Skinned Facade

The double-skinned curtain wall (thermal shaft curtain wall) is based on the principle of ventilation and aims to conserve energy as well as protect the internal environment.

As indicated by the term "double skin" such a facade is intended to mean a system in which two "skins" - two layers of glass - are separated by a significant amount of air space, that is to say, a second glass facade is placed in front of the first. This systems enables air to circulate between the cavity of the two facades, providing excellent air circulation. The type of double skin facade then determines the type of air circulation.

FEATURES

It consists of an outer curtain wall, an inner curtain wall, a sun-shading device, an air inlet device and an air outlet device monitored by an intelligent control system. During summer, the internal air outlet is opened at the lower end of the double-skinned shaft, so that the warm air rises and vents out of the outdoor outlet at the top, thus producing a cooling ventilation system. Additionally, during the winter months, air in the inter-skin shaft is heated by the green-house effect and then let into the internal environment, thus producing a heating ventilation system.

BENEFITS

  • Fresh air is let in from the inlet device, and foul air is exhausted via means of the outlet device, thus preventing the indoor penetration of dust.
  • There is better thermal insulation, leading to savings in energy costs.
  • Better Acoustic Insulation and prevention of external noise, leads to a better working environment.
    • Reducing heating energy requirements
    • Reducing cooling energy requirements
    • Exploiting solar power
    • Natural ventilation
    • Reduced wind load
