  2. Foam concrete - Wikipedia

    en.wikipedia.org/wiki/Foam_concrete

    Foam concrete, also known as Lightweight Cellular Concrete (LCC) and Low Density Cellular Concrete (LDCC), and by other names, is defined as a cement -based slurry, with a minimum of 20% (per volume) foam entrained into the plastic mortar. [1] As mostly no coarse aggregate is used for production of foam concrete the correct term would be called ...

  3. Rigid panel - Wikipedia

    en.wikipedia.org/wiki/Rigid_panel

    Rigid panel. A multi-family residential building under construction with rigid panel exterior insulating sheathing. Rigid panel insulation, also referred to as continuous insulation, [1] can be made from foam plastics such as polyurethane (PUR), polyisocyanurate (PIR), and polystyrene, or from fibrous materials such as fiberglass, rock and slag ...

  4. List of polyurethane applications - Wikipedia

    en.wikipedia.org/wiki/List_of_polyurethane...

    Closed cell polyurethane foam can be used as backfill in applications where the high density and compression strength of concrete are not necessary. [21] In addition to being considerably lighter than concrete, the closed cell nature of the material prevents the transfer of moisture to the structure being supported which can reduce the risk or ...

  5. Polystyrene - Wikipedia

    en.wikipedia.org/wiki/Polystyrene

    According to the EPS-IA ICF organization, the typical density of EPS used for insulated concrete forms (expanded polystyrene concrete) is 1.35 to 1.80 pounds per cubic foot (21.6 to 28.8 kg/m 3). This is either Type II or Type IX EPS according to ASTM C578. EPS blocks or boards used in building construction are commonly cut using hot wires. [54]

  6. R-value (insulation) - Wikipedia

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

    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. [ 3]. R-value is the temperature difference per unit of heat flux needed to sustain one unit of heat flux between the ...

  7. Building insulation material - Wikipedia

    en.wikipedia.org/wiki/Building_insulation_material

    Building insulation material. A building site for a row of riverside apartment blocks in Cambridge. The buildings are being constructed using a systems build with a steel frame and various prefabricated components. The blue plastic on the central building is the vapour barrier for the thermal wall insulation before the exterior cladding has ...
