Replacement Windows Discussion Board Forum

Quick aside, Cardinal doesn't sub out the XL spacer to anyone else, so any window that has the XL (or Endur) spacer system, the IGU was manufactured in a Cardinal IG facility.

Todd, Back before they used spacers to separate the lites in dual pane glass, they used to weld the two pieces together...i.e welded glass. The glass was originally fabricated by either LoF or PPG. You can tell which company did it by looking at the weld. If I remember correctly, if the weld is on t...

I had the same thought as HomeSealed, hoping that maybe you just had the wrong sticker that's why I asked if you could see a difference. And as WoW noted, the difference would be a lot more noticeable from the outside looking in.

When you look at the two windows side by side can you see a color or shade difference between them?

Consider two separate rooms identical in all ways other than one has a window with an STC 40 and the other a window with an STC 30. Imagine an outside noise source that is loud enough to be heard in the room with with the STC 30 but not in the room with the STC 40. Now place those two windows in the...

Wayne,

I don't remember how I came across that video, but i remembered it when I saw your comment and couldn't resist that opportunity!

Nothing is impossible!

I like that IG thickness a lot for both energy and sound performance. I would like it even more if one of those lites happens to be a different thickness than the others, say 4/3/4 or 4/3/3 or even 3/2/3 or 4/2/4.

+10 to recommending WoW.

First a question: you mention that the house is 16 years old so you are planning to replace all of the windows in the house. Why? Are they failing in some way, or is your concern that they are 16 years old so that you believe that they are reaching the end of their life expectancy? I am not recommen...

All good then

What are they telling you about the replacement IG units?? Are they supplying you with any technical information?

I think I'm going to order a higher quality infrared temperature sensor to get a more reliable picture of what I'm really dealing with. This gentleman from Virginia seems to have some very reliable data using an infrared sensor: The infrared thermometer he is using in the video runs about $100 or s...

I agree with HomeSealed's reply.
Seal failure is more about aesthetic than performance.
Replacing the bad IG units isn't going to result in any sort of significant improvement.

All else being equal an improvement of 10dB will cut the noise level through your window in half.
An improvement of 20dB will cut it by 3/4...and so on.

Morning kj, First, starting with pretty much anything that you do should be an improvement over what you have now, but also that low frequency (traffic noise) is about the most difficult to block. You will never eliminate it, but you can definitely turn it down a bit. Milgards Quietline is one of th...
