Installed faced fiberglass batt insulation with its R-value visible (R-21) [1]. The R-value (in K⋅m 2 /W) is a measure of how well a two-dimensional barrier, such as a layer of insulation, a window or a complete wall or ceiling, resists the conductive [2] flow of heat, in the context of construction.

Single pane glass is a very poor insulator (R-value of around 1, RSI below 0.2), so single panes provide very little insulation. Glass coatings are frequently employed such as partially reflective or colored coatings to reduce insolation, and coatings to reflect infrared.
Building insulation: Understanding thermal resistance helps in designing energy-efficient buildings with effective insulation materials to reduce heat transfer. Electronics cooling: Thermal resistance is crucial for designing heat sinks and thermal management systems in electronic devices to prevent overheating. Calculating thermal conductance ...
Although the concept of U-value (or U-factor) is universal, U-values can be expressed in different units. In most countries, U-value is expressed in SI units, as watts per square metre-kelvin: W/(m 2 ⋅K) In the United States, U-value is expressed as British thermal units (Btu) per hour-square feet-degrees Fahrenheit: Btu/(h⋅ft 2 ⋅°F)
The construction industry makes use of measures such as the R-value (resistance) and the U-value (transmittance or conductance). Although related to the thermal conductivity of a material used in an insulation product or assembly, R- and U-values are measured per unit area, and depend on the specified thickness of the product or assembly.

This is a list of insulation materials used around the world. Typical R-values are given for various materials and structures as approximations based on the average of available figures and are sorted by lowest value. R-value at 1 m gives R-values normalised to a 1 metre (3 ft 3 in) thickness and sorts by median value of the range.

A typical window insulation film kit, consisting of plastic shrink film (folded-up) and a roll of double-sided tape. One commonly used film is a heat-shrink plastic which is attached to the window frame using double-sided pressure-sensitive tape. A hair dryer is used to remove creases and improve optical clarity.
