Glazing - double - u<1.1 w/m2k (glazing production - double - U<1.1 W/m2K)

Emissions generated by the activity within the product supply chain as described in ecoinvent v3.10. The product "glazing double U<1.1 W/m2K" describes the processes included in the production of 1.06m2 (corresponding to 1m2 visible area) double glazing (2-IV) with a U-value below 1.1 W/m2K. It can be applied for double glazing used in the building sector. 1 m2 visible glazing area has a final mass of 20 kg. The U-value refers to thermal transmittance which is a measure of the quantity of heat that will flow through unit area in unit time per unit difference in temperature of the individual environments between which the structure intervenes. The cut-off classification is allocatable product. The activity type is ordinary transforming activity. The reference product amount is 1.
