Additional information to the table:
Dimensions and surfaces of single and double glazing units are indicative. Data refers to vertical glazing not higher than 8m above ground level, wedging on four sides and it takes the average wind load in Poland into account. The above mentioned data assumes that the shorter side is >400mm. When using glazing units of different thickness, the thinnest glass is taken into account. When using laminated glass, its thickness should be converted to float glass using the factor 0.63. In the case of double glazing with the use of 4mm thick panes, the maximum side of the square glass pane is 1650mm (+/- 50mm).
