Glazing

All windows and doors from Rationel are delivered with energy glass with a warm edge spacer, which reduces cold bridges and the occurrence of dew and condensation on the windows. The space between the panes of glass is also filled with the environmentally friendly argon gas, which provides significantly better insulation and reduces heat loss. The inner glass pane has a thin, transparent metal coating, which reflects the heat back to the room and ensures maximum light incidence.
