CUBA-DIXON

Project Description

Retaining a incorporating an existing heritage façade with a striking new structure, the Cuba Dixon Development is integral to the Cuba Quarter renaissance. Requiring the roof to act as a structural diaphragm the roof structure was constructed from 21mm plywood.  The blending of a heritage and completely new structure created some unique challenges in terms of roof design and detailing. And because of the buildings location the wind pressures for the roof peaked at around 7.0kPa requiring specific direction from Rooflogic’s structural engineer.

RoofLOGIC SYSTEM

Rooflogic’s Ultratherm Xtreme system was specified for the project, incorporating:

  • RL Vapour Control Layer (installed over plywood substrate.)

  • RL PIR Board (80mm.)

  • RL Roof Board.

  • Fibertite membrane.

 

There were also several plant room areas where the same system was installed over concrete roof slabs.

SYSTEM benefits

  • Engineered to manage extreme wind loads.

  • Verified thermal and hygrothermal performance.

  • Extreme trafficability and chemical resistance in plant areas.

  • Fibertite can accommodate complex details and junctions with the curtain wall cladding.
