  2. Building insulation material - Wikipedia

    en.wikipedia.org/wiki/Building_insulation_material

    Rigid panel insulation, also known as continuous insulation [15] can be made from foam plastics such as polyisocyanurate or polystyrene, or from fibrous materials such as fiberglass, rock and slag wool. Rigid panel continuous insulation is often used to provide a thermal break in the building envelope, thus reducing thermal bridging.

  3. R-value (insulation) - Wikipedia

    en.wikipedia.org/wiki/R-value_(insulation)

    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.

    en.wikipedia.org/wiki/Building_insulation

    In the 19th century, people started to produce insulated panels and other artificial materials. Now, insulation is divided into two main categories: bulk insulation and reflective insulation. Buildings typically use a combination. Insulation is an important economic and environmental investment for buildings.

  7. External wall insulation - Wikipedia

    en.wikipedia.org/wiki/External_wall_insulation

    The thickness of thermal insulation is dependent on whatever type is required in order to create a partition with a heat transmission factor of U=0.25-0.3 W/m2K. When calculating the actual insulation requirements, consideration must be given to current Building Regulation standards.
