Our current door has a one-pane top-level window with retractable screen and/or glass. That feature is nice, but not a necessity in the new door.
How much consideration do I need to consider regarding the frame? Obviously, warping is a concern, but from reading on the net, the storm door is not designed to be air tight or really provide much of an insulation factor (compared to the front door).
What features are important to consider, or would be recommended (frame, vinly-coated, brand recommendations, any major theory differences between the "handle on same side as front door, or opposite")?
Weather-wise, we live in the northeast US.
