Alan Beresford explores the energy-saving and environmental benefits of evaporative cooling for reducing temperatures in buildings.
Cal Bailey shares his hard experience of the benefits of off-site manufacture — especially for pipework.
Microflex preinsulated pipework is available in the UK through Watts Industries. It is composed of thermal insulation around carrier pipe(s) and covered by a double-skinned closed chamber jacket. These pipes can be used for distributing water for heating, cooling and hot and cold water supply services.
