| I hesitated giving a reply. IMHO, you are going about this backwards. You should order the windows to fit the opening, not make the opening to fit the windows. If you are buying stock sized windows they are probably not worth the time/effort to install them. Proper flashing around the nailing fin and sealing air gaps is critical to keeping out water and wind. Otherwise, you may as well leave the windows open all winter.
I don't mean to overcritical, but windows are a major expense, and should be done seldom, but done wrong can be expensive is energy costs, and possibly damage to the house framing. |
