I am looking to replace my windows in my bedrooms. Right now, it looks like there is the original
aluminum window on the inside and on the outside, it looks like a white vinyl window was installed,
almost like a cap that has sliding windows on it. Please look at the pics and see if you can make
heads or tales of what I got.

I was going to buy replacement windows but my friend said new construction windows are better. If I
were to get new construction windows, my he said to get it a little bigger. But, what does that
mean? How much bigger? If I want to keep the existing j-channel siding trim, is it possible to get
the exact size for the new construction windows?

My window sizes are as follows (this is the exact interior measuremnets from side to side:

46" (w) x 39 1/2" (h)
34" (w) x 39 1/2" (h)



Thanks

Tony
