Need of Insulation / Why to insulate?
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.
Insulation is an integral part of every home, office and public building. It is in the cars we drive and the appliances we use to keep and cook our food, and to keep us warm in the winter or cool in the summer. By increasing the efficiency with which we use our energy it helps to safeguard our stocks of fossil fuels, and it reduces the amount of CO2 we release into the atmosphere as a result of our daily activities, helping to ensure that we leave behind a healthy world for future generations.
Insulation helps to fight global warming as it reduces the amount of fossil fuels, such as oil and gas that we burn for energy and thereby reduces the volumes of greenhouse gases we release into the atmosphere. Reduction of greenhouse gas emissions is an ecological function of insulation..
Thermal insulation reduces heat wastage, which in turn means we need less energy for our heating and cooling systems. Effective insulation can therefore reduce our energy bills, energy consumption, and related pollution, by up to 80%.
Comfort in summer and winter
Comfort in our homes and workplaces rely on us maintaining a good inside temperature regardless of the season. To maintain comfortable temperatures by conditioning the air within by the use of HVAC equipment, either in winter or in summer, we need a combination of effective thermal insulation throughout the building (including windows); ventilation system adapted to the season; tight fitting doors, shutters etc and an airtight building envelope to keep out draughts.
Over last few years, noise has become an increasing problem, as traffic, running of equipment and processes are getting noisier and the need quite condition is increasing. Man is incapable physiologically of blocking out unwanted noise, unlike blocking out wanted light which is done by simply closing the eyes. Prevention of stress and even more serious health problems that can result from excessive noise, require external Noise control measures through effective acoustic insulation in buildings along highways and around noisy equipment.
