I have single pane windows installed in my 1yr old house in hurricane country, yet I have 8" reinforced concrete walls. Go figure. I want to put in dual pane windows but I only want to replace the windows and their frames. It looks like there is plenty of room to have dual pane windows. Is this possible?

Thanks in advance...John

 

What type of windows do you have now? Wood double hung (up and down movement?), aluminum sliders? Bit more info needed....

Wait... 1 yr old???? How can that be?

 

They are aluminum double hung windows. The builder is out of business so I can't ask him anything.

 

Well, out here in AZ, you can get replacement vinyl or aluminum windows that will fit into the existing frame. You lose some glass area, but they're about 30-45 min replacement per opening. Taking any sort of new window out is going to be a major PITA, sice they are all installed with a nailing flange. I'd try to identify the manufacturer of the window and see if they offer any sort of replacement sash with double pane/LO E glass.

I guess it's real hard to believe that single pane windows could even pass most codes, esp down where you are. FL? TX? Have you checked into that?

 

Yep, FL. I just left AZ to try my luck here. The AZ home was built in '94 and had dual pane. Unbelievable that they have single here. I have spoken to several other homeowners in the same city and they have single pane as well. I'm in Central FL so maybe they have different codes. I haven't yet talked to the gov't agencies.

Thanks for the info...John
