   It's a humidity problem in your home. Windows do not cause condensation. Call Andersen @ 1-888-888-7020 and they'll send you literature and a DVD on how to deal with condensation problems.

   Or google "windows do not cause condensation" (with the quotation marks).

   CJM gave you a hint. You need to ventilate. Common problem I've seen is .... seal, seal, seal .... then put in a crummy exhaust system (i.e. bath fans) that doesn't work. If flex duct was used for your bath fans ... that is a high probability that you aren't ventilating at a rate you might think you are. I've even seen an exhaust register using a round eave vent get painted over so much that it limited air flow.

   You need to vent at a rate that you produce moisture for a balance. It's not your windows, man, it's your moisture generation and your moisture control.

   The moisture is a combination of new construction moisture getting trapped in the house and  poor air flow around the windows..

     In floor radiant heat is wonderful.. except for the heat losses around windows..

     Thermally speaking think of a window,  even the best window as having an R value of 3 (at best) 

     Your walls may have an R value of 19 so the windows are cooler than the walls which cause moisture to condense on them..

     To solve the problem aim fans at the windows and it will help.  Better still is eliminate as much moisture as you can. Coooking, showers, plants, and people all add to the moisture load..

      Do you have a humidifier?

      Do you have a HRV unit?

   If it's a brand new home, understand that it takes a year or two for the building materials to dry to "normal" levels, and during that period you'll have higher humidity than normal.

   But new homes should have some sort of ventilation system to eliminate excess moisture. This is generally required by code, so see if your house doesn't have a system that just needs adjusting. Keep in mind that the inside humidity needs to be dialed down as it gets colder outside.

   Use vent fans in the bathroom when showering, and in the kitchen when cooking.

   If you have stained wood window sash interiors, use a furniture oil on them to lessen the effects of the moisture. Try to keep it off of the glass (and plastic parts), though, as it will make a mess.

   If you have curtains on the windows, leave them open when it gets cold, until you have the situation controlled in other ways.
