How Does Insulation Work to Keep Heat Inside a Home?


What is Insulation?

  • Insulation is a substance installed to lessen the rate of heat transfer. Insulation keeps a home warm and preserves the comfort of humans within their home and work environments. Many locations experience great changes in temperature throughout the year and when these changes occur, people require a comfortable temperature setting in their homes and places of work. The best insulation material for a home keeps in the heat during cold weather and does so by blocking the flow of heat.

How Does Insulation Work?

  • Thermal insulation, which is in many homes and buildings, is believed by many to be the most common type of insulation. The design of thermal insulation is intended to decrease the transfer of heat between the interior of an edifice and the outside. Thermal insulation helps a building to maintain heat throughout the winter season. It also helps the building to remain cool during the summer months. Although, no material can completely hinder the transfer of heat from one area to another, there are; however, many resources that can slow down the transfer process. Building edifices must meet certain specifications to be considered properly and thermally insulated. The building must be airtight to keep air drafts from occurring. If the home is not airtight, no amount of thermal insulation will be capable of maintaining heat in the home. When a home or building is airtight, the insulation is effective.

The Different Values of Insulation

  • Insulation materials have a certain R-value assigned to them which measures the thermal resistance of the material. Therefore, the performance ability of insulation material is according to its R-value. It is the attribute that determines the value of the insulation material and how effective it will be. R-value insulation is considered by many to be one of the best insulation choices in comparison to a material labeled with a different or lower value. The higher value insulation material is capable of averting more heat transfer because of the density, thickness and structural makeup. Higher value insulation materials consist of additional layers that increase the effectiveness of the product. The more thermal layers present, the greater amount of heat is prevented from being transferred. This is accomplished by the thermal layers reproducing and reflecting the heat waves and conduction that is present in heat.
