you have not more precise as information?
it is not necessary to give a global profitable or unprofitable answer which does not allow to understand ... it is necessary to give precise figures on the heat losses, and on the prices
for the prices if the triple glazing of the trade are too expensive it does not matter it is possible to make them otherwise
pay attention to the notion of heat loss proportional to the temperature difference between the interior and the exterior ... this is already more or less true for insulating them from walls ... this is completely false for what is transparent ... the figures given by the window manufacturer are therefore just valid in the test conditions defined by a certain standard ... for reality it is like the consumption in liters per 100 of the car
