2. Building insulation material - Wikipedia

   en.wikipedia.org/wiki/Building_insulation_material

   Rigid panel insulation, also known as continuous insulation [13] 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.

   The Energy Saving Ordinance (EnEV) 2013 clarified the requirement of thermal insulation of the ceiling. And it mentioned that if the ceiling was not fulfilled, thermal insulation will be needed in accessible ceilings over upper floor's heated rooms. [U-Value must be under 0.24 W/(m 2 ⋅K)] [31]

4. Spray foam - Wikipedia

   en.wikipedia.org/wiki/Spray_foam

   Spray foam insulation or spray polyurethane foam (SPF) is an alternative to traditional building insulation such as fiberglass. A two-component mixture composed of isocyanate and polyol resin comes together at the tip of a gun, and forms an expanding foam that is sprayed onto roof tiles, concrete slabs, into wall cavities, or through holes ...

5. Superinsulation - Wikipedia

   en.wikipedia.org/wiki/Superinsulation

   There is no universally agreed definition of superinsulation, but superinsulated buildings typically include: Very high levels of insulation, typically R-40 (RSI-7) walls and R-60 (RSI-10.6) roof, corresponding to SI U-values of 0.15 and 0.1 W/(m 2 ·K) respectively)

6. Cellulose insulation - Wikipedia

   en.wikipedia.org/wiki/Cellulose_insulation

   Demand for insulation increased following the oil embargo of 1973–74, which caused energy costs for heating to skyrocket across the United States, driving interest in energy conservation. Insulation gained significant national attention in the U.S. as a cheap and available technology to increase the energy efficiency of homes. In 1977 ...
