Situated in the Hertfordshire countryside, Centurion Club offers members and their guests the finest facilities and customer service both on and off course. The 18-hole course offers a challenging mixture of holes meandering through pine woodland. The clubhouse includes a luxury restaurant overseen by Michelin-starred chefs’ Chris and Jeff Galvin. A recessed roof terrace was incorporated into the building design to take full advantage of the views across the lake and 18th green, extending the bar’s seating area.
The optimum performance insulation solution features vacuum insulation panels (VIPs) with a microporous core which is evacuated, encased and sealed in a thin, gas-tight envelope. With a declared thermal conductivity 0.007 W/mK, OPTIM-R VIPs can deliver an insulating performance better than that of commonly-available insulation materials. This performance means that the product can be specified in nominal thicknesses.
The system was installed on the terrace below Thermataper TT47. The use of this product eliminated the need to incorporate a structural fall into the design, and provided a lightweight and dry alternative to screeding.
