. Saint-Gobain: Walls and Ceilings Covered at V&A Silo District Saint-Gobain worked closely with the professional teams and the V&A to provide a comprehensive and technical approach towards ensuring that the best product choices were made. S aint-Gobain has been involved on the Silo District since the initial development of No 1 Silo. The use of drywall has become a recog- nised standard across all the district. Silo Hotel Setting a new standard for luxury hotel accommodation, the new Silo Hotel sits above the recently opened Zeitz MOCAA, occupying six floors in the museum’s grain elevator area. Janet Thompson, Saint-Gobain Gyproc’s regional technical and specifications manager in the Cape, detailed some of the challenges that Saint- Gobain needed to address. “The original Grain Silo building was a heritage site and because of this the developers at the V&A Waterfront required materials that would support the building’s unique construc- tion requirements for both the museum and the Silo Hotel. The project called for lightweight yet high-strength wall and ceiling materials that would enhance visual appeal while adding practical value.” Saint-Gobain Gyproc was contracted to specify material for the Silo Hotel and with drywall lightweight construction proving to be the best way forward, 15 different types of plasterboard were brought in that were selected based on their sustainability, acoustic, fire rating and thermal properties. 56 These components are particularly necessary in a luxury establishment like the Silo Hotel, where privacy within rooms, safety of guests, aesthetic appeal and reducing maintenance become important considerations,” explains Thompson. Taking into account privacy for guests, her first port of call was to introduce twin stud and tracks and as a result achieved a 63 dB sound rating, a great improvement on the traditional 48dB. For fur ther acoustic comfort, Gyproc Acoustic Rigitone was installed in the study and private restaurant area to allow for quiet and discretion and to ensure thermal comfort. Isover EnergyLite Acoustic Insulation was installed in the ceiling. Following this, Gyproc Cretestone was specified for all the rooms and bathrooms to complement the drywalls and provide aesthetic appeal. Plasterboard was selected that helped the building reach a one-to-two hour fire rating. To control moisture levels in bathrooms, Gyproc Moisture Resistant RhinoBoard was installed. The toilets and vanities are hung to the drywalling thanks to a special reinforced bracing. Ceilings comprise Gyp- roc Cretestone skimmed 9.5mm RhinoBoard and the rooms are adorned with decorative bulkheads. Plasterboard also allowed for a sustainable construction project. “Our products are made using less water at factory level and require no water on site. There were also time and money-saving benefits to using drywall. Thanks to plasterboard being ten times lighter than brick work, there was a 17.5% structural cost saving as well as a significant time saving component, as the project was completed earlier than anticipated. “Specifying materials for this extra- ordinary luxury hotel and considering products that resulted in an end-product which is not only sustainable, but encompasses the safety and comfort features we set out to achieve, has truly been both a privilege and highlight,” Thompson concludes. Zeitz MOCAA Crucial to the redevelopment of this heritage site into the Zeitz MOCAA was selecting the right interior construction materials during the design phase. Mark Noble, Development Manager at V&A Waterfront, required materials that would not only support the museum’s construction requirements, but that met budget parameters and were environ- mentally friendly. “We wanted to preserve the integrity of this 96 year old building,” Noble explains, “while converting it into a space that encompasses the comfort and sustainability of a world class museum.
