Replacement Windows Discussion Board Forum

Great analogy! But the performance really does go down as the width increases. Imagine the Xenon gets to a60mph peak in 4 seconds, and then drops down to 54mph over the next minute. The Krypton gets to 58 in 6 seconds and stays there for the next 10 seconds and then drops down to 53 over the next mi...

Marvin uses the Cardinal XL on almost all of their products.

I was researching the internet this morning, hoping to find a graphic presentation of spacer performance. Unfortunately, I couldn't find one anywhere. Oh well. Thanks for the clarification FenEx about IGU width and airspace width -- I hope that I wasn't confusing when I was discussing gap spacing ve...

Go for the Hot Tub!

I didn't answer the second question. Gap width can effect the overall energy efficiency of the unit. But, when considering a dual-pane IGU with argon and a soft-coat Low-E, 7/16" thru about 3/4" gap is not going to display a radical differentation in performance. A 7/16" gap is about ...

I am assuming that you are talking about the air gap between the two lites in an IGU. I will answer accordingly. You are a window manufacturer. You have several different glass thickness options available in your IGU's...possily even laminated glass. Now consider having only a singel spacer (gap opt...

Steve, As a follow up to Guy's recommendation, I would recommend using alcohol with the flat blade knife to lubricate the glass and blade as you scrape. Use only short, relatively gentle strokes and then only one way, Do Not scrape back and forth...push the blade forward, but do not drag it back. An...

WS, this is a reply that I posted on "Mark's" SHGC question. Perhaps it applies a little bit here as well. Actually Mark, there may or may not be much that you can do to customize a particular SHGC from the window manufacturer; but knowing possible options is certainly not a bad thing. The...

Actually Mark, there may or may not be much that you can do to customize a particular SHGC from the window manufacturer; but knowing possible options is certainly not a bad thing. The particular Low-E coating that is used in the IGU is what determines your SHGC. As a general rule, you want a low SHG...

1) In the overall scheme of a homeowner picking out replacement windows, how much should we worry about which spacer system is the window we are looking at? ~ I would suggest that it really is more important for a consumer to find a company that builds a quality unit and also ensures a quality inst...
