Our wood frame glass patio door is rotting out at the bottom. Hubby and I plan to replace it and want info as to our best option. We live in Iowa (cold and windy winters!!) and the door has a north exposure to the winter winds. We're looking at every option from the $400 budget doors to the $2400 high-end with triple glass and inside shades. We wouldn't mind paying the price (and the installation) if we know the end product will do a good job of sealing against the cold. We note that some sliders are on the outside with screen on the inside. Some have the screen on the outside and the slider on the inside. Some have that fuzzy felt type gaskets. Some have rubber. Different sales people tell us different things. Can you give us recommendation as to what is "a must" and and whether the high-end models actually are warmer? Thanks.

I recently had to remove my kitchen/hallway door whilst installing laminate flooring. The door has a spring-loaded chain near the middle hinge as a fire safety device that pulls the door shut which I also unscrewed. The trouble is I have put the door back on but the device is too strong to screw back into place as it is sprung very tightly. Does anyone know a good way to re-fit this that isn't going to involve losing a finger? Thanks
