'Chill Stores' are a common use for steel framed buildings. A typical internal temperature of a 'Chill Store' starts at 0-2°C up to 5-8°C. To achieve these figures air tightness of the strucutre is vital. The Twin-Therm® Chronus specification is an enhanced version of the market leading Twin-Therm® Roof & Wall Cladding system. Twin-Therm®Chronus is specially designed to meet 'Chill Store' requirements.
