Re:Entry Door Insert, Slightly OT question!

Since the city mandated them, maybe they'll pony up the money for the replacements? ;>)

What would be the point in drilling the glass? You won't eliminate the condensation, and all you will do is have water running down somewhere creating a possibility of wood rot, further compounding your problems.

Replace them with windows from a reliable, old-line company. Bubba's Pretty-Fair Insulated Glass Company isn't the right choice.

I would replace the windows too. If cost is an issue right now, you could try to drill a couple of small holes. In our winters, the condensation is caused from interior water vapour getting between the glass layers and condensing on the colder glass surface. The exterior air in winter here is very dry.

The conventional thinking is that with a couple of small holes at the bottom of the exterior pane of glass, this moist air can breath out and be replaced with the drier exterior air. Over time the condensation should disappear.

i think you should replace them all with stained glass. i'd be happy to do the work for you. Most codes have an allowance when using leaded glass. m

It won't work if you drill holes only in the bottom. It WILL work if you drill holes top and bottom. This creates a "chimney" effect so air will enter the bottom holes, travel up the inside, and vent out the top holes. This top/bottom venting is, for many glass artisans, the preferred method of installing stained glass panels.

This fella is only one of thousands that have disovered the hard way that many sealed units fail to stay sealed. It's why stained glass panels should NOT be installed sandwiched inside such likely to fail sealed units. Instead they should be installed separate from sealed windows with allowance for ventilation.

Here's an explanation of how to provide such installation:

Hi Charles,

I live in New Brunswick, Canada. My home is 29 years old and has the origional "Vented casement windows", manufactured by Pella Windows. Each window is double glazed with 11/16" spacing between the glass. They have four

1/4" holes, two on each side between the glass, going from the inside of the frame to the outside drilled parrallel with the glazing. The way the window frame is designed the holes are not exposed to the outside elements. They are located 3" from the upper and lower frame. These windows do not get condensation between the glass. This winter we had temperature extremes of -35 F on a Friday night and up to a +40 F by Sunday afternoon. That is a 75 degree change with no condensation. I must admit to one of the windows steaming up a number of years ago. It was caused by some type of wasp crawling into the holes and plugging them up for a winter hibernation. The cure for that was checking each one of the holes when we wash the windows in the fall. No wasp = no condensation.

If you decide to drill it would have to be on the outside otherwise warm, moist air would be exposed to the outside cooler pane all the time.

Hope this helps,
