Heat Shield Insulation - What Is It?

Heat Shield Insulation, more commonly referred to as R-values, is a measurement of radiation efficiency. This is calculated by multiplying the flux (energy) required to heat an object with the specific resistance to heat. The larger the R-value, the more efficient is the insulating material. Some commonly used materials for high-R-value heat shields are brick, ceramic tile and stone. Although most building codes do not require heat shield insulation, it has been found that the flooring surface temperatures of many commercial buildings can be reduced by incorporating it into the existing building design. This method of reducing outdoor temperature will reduce energy costs.

The components of the thermal heat shield insulation  are primarily comprised of radiant heat-absorbers or R-frames, reflective foil-board, fiberglass cloth or paper, and high quality roofing materials. Each component must be combined with appropriate materials for a specific application. Improper installation of the component will not only result in increased heating costs but may also weaken the structure of the building. Also, improper installation of the radiant heat-absorbers will not provide the optimum performance. Most construction companies will suggest to the customer, either through installation or simple testing, which components are appropriate for use with certain roofing systems.

Radiant Heat-Absorber: A radiant heat-absorber is a material, typically made from metal or ceramic tile, that reflects infrared radiation. The reflection of this radiation actually heats the space that it is in. A metal or ceramic tile with a high R-value is usually preferred. This material is often called a radiant heat shield insulation material because it effectively dissipates infrared radiation from the environment. Typically radiant heat shield insulation materials are measured in degree-of-passage. Find out more about heat shield insulation here: https://shannonglobalenergy.com/heat-shield-insulation/.

R-frames: Also known as R frames are aluminum frames that allow for the installation of flexible sheet metal roofing systems. These materials can be used for roofs above grade or for attic applications. Aluminum is favored because of its heat-resistant properties. Also, it is a light-weight material that does not add structural weight. Fiberglass and steel are other options for insulation materials.

Asphalt shingles are typically the most effective roofing option. These materials are commonly used for attic applications or on grade roofing systems. They are also the most popular choice for covering the lower slope areas of an asphalt roof. Asphalt shingles are a very cost-effective option for providing thermal resistance to the atmosphere. There are a variety of types of asphalt shingles including: single skin, double skin, and three-skin. They are typically available in several thicknesses.

R-values for these roofing materials can vary depending on a variety of factors including roof construction, insulation requirements, and climate. Other roofing materials that are also available include: metal, ceramic tiles, hardiplank, slate, and wood. Each of these materials are designed to have differing levels of thermal conductivity. They are also available in different types such as: single skin, double skin, and three-skin. When purchasing these materials, you should consider your insulation needs and the climate in which you live. Explore more about heat insulation at https://en.wikipedia.org/wiki/Thermal_insulation.
