Whenever we have a surface at a temperature different from that of the ambient which surrounds it, we can have energy loss due to the temperature differential. This can be most significant when the differentials are large- as in Furnaces, Power Stations, Refineries or in low temperature storage for Liquefied Gases (Natural gas, Ethylene, Propane, Butane or Ammonia). Insulation is necessary to reduce energy consumption, sound pollution and improve the comfort and quality of life in new or existing installations and buildings, regardless of the construction method. Insulation is also provided to provide safety against possible burns to persons who may come in contact with a hot surface.

Where to install insulation will depend on the type and design of the equipment or process to be insulated.

The more insulation you deploy, the more you will save in energy costs and increased efficiency. However, where to put the insulation will depend on the equipment or process involved, and how it has been designed. The primary consideration must always be safety, and therefore hot pipes and equipment within a working area must be insulated, especially if they are operating at above 60°C. The same applies to chilled pipes and equipment operating at more than 10°C below ambient. Insulating hot or cold processes and plant will make them more economical and environment-friendly to run, as they will require less energy, and therefore be responsible for less atmospheric emissions. However, efficient insulation will also make a process more thermally stable and thus help to reduce breakdowns and maintenance costs. In addition to providing excellent thermal and fire performance, insulation products from Lloyds possess excellent acoustical properties, which help to reduce noise transmission from noisy equipment, such as Diesel Generating sets, compressors, Gas turbines and stacks, pipe and ductwork systems. It has become a statutory requirement to ensure quiet conditions in work places and in areas close to residential spaces.

• • Select the most appropriate insulation product for your application, bearing in mind temperature of operation, shape and size of item to be insulated, performance requirements including acoustical duty etc. • Having selected the correct material, ensure that the application is carried out scientifically by applicators having sufficient knowledge and experience. • Remember to consider various factors such as condensation risk avoidance to prevent corrosion on steelwork, and incorporate an effective vapour barrier at the right place. • Do not leave sections Un-Insulated and do not leave gaps between adjacent sections of insulation – if necessary fill difficult spaces with small off-cuts or with loose wool. • Be aware of local and national legislation and standards that may affect the type, design and thickness of the insulation products you use. • Always follow the manufacturers’ instructions when fitting insulation products and systems. • If in doubt, refer to Lloyds technical help line for advice before drawing up the insulation Remember, it is always easier and more cost-efficient to install higher levels of insulation at the project construction stage, than to have to retrofit additional layers at a later date.
