Be sure to check the laws and rules covering window replacement in the city or county where you live. As an example, where I live as long as the opening is not increased no permits are required so window replacement means to remove the original glass and measure carefully to get the size that slides into the existing frame. When I did ours a couple years ago I used a tube and a half of the sealer to insure the windows had no leakage. The store where I bought mine had the sealer which is much stronger than the kind at HomeDepot or Lowes and I bought several large clamps to pull the window in very tight before I drilled holes for screws, very long screws, two in each side and four in the top, none in the bottom. Our large bedroom window I ordered one that has both halves move and/or removeable to allow max air flow.
