Understanding The Basics About Thermal Insulation

By Karen Gibson


Thermal insulating refers to the process of reducing heat transfer between objects that are in thermal contact or in range of radiative influence. There are many different ways of achieving thermal insulation including the use of suitable materials and object shapes. There are also several specially engineered methods/processes for achieving this goal. In Richardson, TX, there are several companies that specialize in providing these services to clients of various types in the whole of the United States.

When two bodies have different temperatures, they inevitably allow heat flow between them. The heat flows from the body at a higher temperature to the body at a lower temperature until the two bodies attain the same temperature. The application of insulations reduces thermal conduction or cause reflection of thermal radiation as opposed to allowing it to get absorbed by the body whose temperature is lower.

Living organisms as well as manufactured products have many applications for insulations. Solids and liquids have been determined to have better thermal conduction properties than gasses. For that reason, trapping gasses in spaces produces very effective insulating materials. The gasses need to be trapped in small cells to prevent them from undergoing natural convection.

The use of gasses to insulate is used widely by manufacturers in various applications. To attain a cell formation, air is trapped in foam-like structure using polymer or glass material. Industrial application of this concept is used in piping and building insulations, which include cork, cellulose, urethane foam, rock wool, perlite, vermiculite, glass wool, and polystyrene. All highly insulating clothing materials like fleece, down feathers, and wool heavily rely on the principle of trapping air. Homeothermic animals reply on air-trapping property to stay warm too.

The maintenance of acceptable interior temperatures on a global scale contributes to the enormous global energy consumption. Insulating buildings is usually based on air-trapping concept. Homeowners can save a lot of money if they insulate their homes adequately using proper materials. Well insulated spaces also have uniform temperatures and less temperature gradient in horizontal and vertical dimensions.

Insulations are also capable of reducing noise and vibrations felt in the rooms they are installed. The source of noise and vibration may be outside or inside the building. Insulating against noise and vibration promotes a comfortable environment within the building. In industries, a lot of energy is spent on lowering, maintaining, and raising the temperatures of objects. To keep the amount of energy needed low, the objects are usually insulated suitably.

The level of efficiency in a material is usually determined by several different factors. Among the most influential factors are the thermal conductivity, surface emissivity, thermal bridging, thickness, density, and specific heat capacity. These factors vary in different insulations. How effective a material can insulate against the loss of heat usually deteriorates with time. The causes of the deterioration are changes in environmental conditions and aging among others.

Different insulations cost differently. The best insulators usually cost very expensively. The installation of insulations needs to be done by a professional so that they can work properly. Poor installation can impede good results greatly.
