Do they save on heating and cooling costs?
Using thermally efficient roofing materials as supplied by CRiL™ help reduce cooling and heating costs. In summer, a lightweight insulated roof from CRiL™ can assist in minimising the amount of heat radiated into the building after sunset. Metal sheets have low thermal mass, so it cools down fast once the sun sets. The choice of colour can also influence thermal performance. Lighter colours, in particular, radiate less heat during summer.
