2. Underfloor heating - Wikipedia

   en.wikipedia.org/wiki/Underfloor_heating

   Underfloor heating and cooling is a form of central heating and cooling that achieves indoor climate control for thermal comfort using hydronic or electrical heating elements embedded in a floor. Heating is achieved by conduction, radiation and convection. Use of underfloor heating dates back to the Neoglacial and Neolithic periods.

3. Capillary tube mat - Wikipedia

   en.wikipedia.org/wiki/Capillary_tube_mat

   Here capillary tube mats were used for the first time in a complex system in a residential building with a floor area of 1,200 m 2. Extensive scientific work by Prof. Dr. Mathias Fraaß (since 1991) and later by Prof. Dr. Bernd Glück (since 1994) created the necessary basic principles on the theory in the applications for capillary tube mats.

   Conductive mats are made of carbon and used only on floors for the purpose of drawing static electricity to ground as quickly as possible. Normally conductive mats are made with cushioning for standing and are referred to as "anti-fatigue" mats. 3 ply static dissipative vinyl grounding mat shown at macro scale

   Increasing concrete water content; Increasing concrete porosity; Increasing temperature; Increasing chloride content; Decreasing carbonatation depth; When the electrical resistivity of the concrete is low, the rate of corrosion increases. When the electrical resistivity is high, e.g. in case of dry and carbonated concrete, the rate of corrosion ...

7. Cross-linked polyethylene - Wikipedia

   en.wikipedia.org/wiki/Cross-linked_polyethylene

   A cross-linked polyethylene (PEX) pipe. Cross-linked polyethylene, commonly abbreviated PEX, XPE or XLPE, is a form of polyethylene with cross-links.It is used predominantly in building services pipework systems, hydronic radiant heating and cooling systems, domestic water piping, insulation for high tension (high voltage) electrical cables, and baby play mats.
