Has anyone had experience using Pozzi windows? We're getting mixed opinions from contractors who have used their windows. One told us that they all fogged up. A call to corporate told us that their "insulated divided lites" had problems and were discontinued Dec 99. Apparently they are now using what they call a "capillary" or "breather" hole to vent moisture; they say that "all" gas-filled windows leak after about 5 years.
