Unitised systems

WHY UNITISED?

The Benefits

Unitised curtain walling brings all the advantages of off-site construction to the building envelope.  These include:
 
On site

• reductions in time on site of up to 70 per cent
• improved safety – fewer operatives are required on site, the need for scaffolding is eliminated and there are reductions in working at height
• earlier fitting out as the building envelope to each floor is completed
• construction is less affected by inclement weather
• storage of cladding materials and glass handling on site can be completely eliminated -  a major advantage for constrained city centre sites
• more efficient control of materials, including less wastage, loss and damage
• the construction programme is more predictable and delays on site are less likely
• the façade panels are manufactured off-site and craned into position, making this a highly efficient solution where site access is restricted.
  

Quality and Performance

• significantly improved quality and performance because the façade panels are completed off-site in a controlled factory environment
• higher quality interfaces because design responsibility for the complete envelope is with one team, led by Wicona
• accurate installation using a range of adjustable fixing systems

Cost Effective

• there are cost savings on site preliminaries and scaffolding
• the option of standardisation for economies of scale and material optimisation
• suitable for both new build and refurbishment
• the system can be supplied from stock for fast track projects
• faster programme times leading to earlier occupation and a faster return on investment for the developer.

Aesthetics – Complete Freedom of Expression

Unitised curtain walling offers architects and specifiers complete freedom of expression, with any combination of profiles, infills, external feature caps and glazing specification.

The system can be adapted to specific project requirements and new designs can be developed for more complex façades.

The curtain walling combines all the benefits of off-site construction with the possibility of aesthetic variations, incorporating:

• stone cladding
• metal, composite or polycarbonate panels
• windows, doors and fixed light glazing
• brise soleil sunshading
• photovoltaic panels

Options include:

• slim-line sections with overall site lines of 70mm or 90mm
• different fixing configurations giving specifiers the option of façade panels which are flush to the floor
• panel sizes of up to 4m by 4m can easily be accommodated

Construction

The unitised system is fully glazed and sealed off-site.  Gaskets and glazing beads are installed in factory controlled conditions before the complete units are moved to site for fast and easy installation onto pre-prepared fixings.

The panels can be fixed to steel or concrete frames for further design flexibility and installed using a platform or hoist, eliminating the need for scaffolding.

Testing and Certifications

The Wicona unitised system is fully tested to the most stringent European standards for air permeability, water tightness under dynamic and static pressure, and wind resistance.  Reference IFT Rosenheim Test Report No: 108 29634e*, 10 May 2005.
