Rationel ENERGY
- reduce the heating bill
The space between glass layers is most often filled
with argon, which insulates better than ordinary air.
Low energy panes help lower the heating bill, because they
reduce both heat loss and down draughts. Low energy panes
feature a thin coating on the inner side of one of the glass
layers. The coating reflects the heat back into the building and
thereby reduces heat loss even more. The coating is
almost neutral and is designed to let in a maximum of daylight and
solar heat.
Rationel ENERGY panes provide a bright, pleasant indoor
environment with a colour reproduction as neutral as technically
possible.

Values according to EN 410 and EN 673 (dT = 15K filling degree =
90%).
Table values apply only to the window pane.
LT- and g-values are given as percentage of light / heat that
penetrates through the pane.
Rw = sound reduction measured in dB
