At CMS Façades, we provide a high-quality specialist service with a highly personal approach.

We understand that while no two construction projects are the same, every one is equally complex in its own way – and the importance of clear communication and responsiveness at every stage of the project delivery is crucial to the successful management and completion of each one.

Our tried and tested processes have been developed to deliver total façade solutions to meet project deadlines. Our objective is to provide a healthy and safe working environment for all stakeholders at all times with a target is of zero accidents in the delivery of works throughout.

 

STANDARD CURTAIN WALLING

In stick construction, the curtain wall frame is constructed mainly on site with mullions and transoms supporting glass, spandrel panels, metal panels and brise-soleils, connected piece by piece. Each mullion is usually supported by the floor or perimeter beams.

Stick curtain walling systems are versatile and allow for the integration of other systems, such as sliding doors and windows. They tend to be less specialised as they are not dependent on having a large factory. However, stick systems do require multiple steps to erect and seal the wall, which means more time is spent on site – an approximate rule of thumb would be that 70% of the work is carried out on site, with 30% in the factory.

BENEFITS OF STANDARD CURTAIN WALLING

  • Shorter lead times to site
  • More economical if the building facades require lower volume of curtain walling
  • Off the shelf systemised solutions
  • Concurrent manufacture and site preparation – units can be assembled while the structural frame is being built. The facade can also be completed a floor at a time, allowing parallel internal work

SEMI-UNITISED CURTAIN WALLING

Semi-unitised curtain walls incorporate techniques from both stick systems and fully unitised systems. The fixed glazing and openable vents use the same carrier frame, giving a uniformed sightline. This system also lends itself to easier penetration for fixing external screening. Structural glazed systems also use semi-unitised curtain wall techniques. The grid is fixed to the structure, and factory-bonded panels are “toggled” or directly fixed to completed framing.

BENEFITS OF SEMI-UNITISED CURTAIN WALLING

  • Shorter lead times to site
  • Improved quality control
  • More economical if the building facades require lower volume of curtain walling
  • Off the shelf systemised solutions
  • Concurrent manufacture and site preparation – units can be assembled while the structural frame is being built. The facade can also be completed a floor at a time, allowing parallel internal work
  • Quicker installation, requiring less manpower on site than Standard Curtain Walling
  • Can be installed from the interior of the building. This is ideal for high towers or building sites where there is a tight footprint
  • Less space is needed on site for layout – another advantage

UNITISED CURTAIN WALLING

In unitised construction, the curtain wall is composed of large units that are assembled in the factory, shipped to the site and erected on the building. Aluminium profiles are used to form the frame, which is normally one-storey high. Opening vents, glazing and infill panels are built into units before being transported to site. As with stick construction, each unit is usually supported by the floor or perimeter beams.

BENEFITS OF UNITISED CURTAIN WALLING

  • Improved quality control
  • Concurrent manufacture and site preparation – units can be assembled while the structural frame is being built. The facade can also be completed a floor at a time, allowing parallel internal work
  • Quicker installation, requiring less manpower on site
  • No need for scaffolding
  • Can be installed from the interior of the building. This is ideal for high towers or building sites where there is a tight footprint
  • Less space is needed on site for layout – another advantage
  • They do not transfer impact noises from floor to floor or horizontally from room to room.
