A GREAT friend of mine who is a Manufacturer's rep for Marvin Infinity windows, has a "situation" with one of his dealers customers. Rather than me explain it in detail, I'll just copy you in on his email to me....
John, I need a small favor from you. I’m wondering if you can post a question, based on a scenario that I am having, on contractor talk. I need some good feedback from some experienced HVAC guys.
Here is the scenario: I have a homeowner near Flint, MI who had Infinity windows installed in 2010. It was a full frame tear out and replacement. The old windows were steel framed units from the 1950’s.
My local dealer did an excellent job with adequate insulation and caulking where necessary. The homeowner insists that her home has felt colder ever since, with this winter being exceptionally bad. She says that she feels drafts across her face when sleeping at night and most of the rooms are generally colder. She is using the same CF (relative to other comparable years) of gas with the new windows.
Here is what I can tell you about the house. It is a one story ranch with a full basement. It has baseboard boiler heat with no cold air returns. The boiler is in the basement along with an original fireplace which they use almost daily during the winter. The prior homeowners had attic and wall insulation blown in.
Now, my guess on this (but bow to your more experience and expertise), is with the unprecedented weather we had this winter, and even with new high performance windows, the inside glass was colder than the previous windows probably ever got. Thus cooling down the air right inside the window quite a bit.
Then with the extremely warm hot water heat right under the window, it created some pretty large temperature differences right around the window glass, resulting in some pretty hefty, artificial drafts.
Kind of like what happens to the shower curtain ten minutes into a really hot shower and then someone opens the bathroom door. Cooler air from outside the bathroom comes rushing in and it "blows" the shower curtain in around you in the hot shower.
I'm going to link him into this thread so he can see your replies.
Thanks in advance! :thumbsup:
