Doors are necessary for access and often for ventilation and illumination too. However, if they are in poor condition (or just very old) they can contribute to high amounts of air leakage and related energy losses.

Exterior Door Replacement

Modern exterior doors often fit and insulate better than old ones, and their associated heat losses (or gains) come from opening and closing the door. However, damaged weatherstripping can increase energy loss around the door by many times. Check your weather-stripping every year and replace it as needed. After replacing the weather-stripping, check the door seal again. If the door still does not seal tightly to all sides of the jamb you either installed the weatherstripping badly or the door is bent and in need of replacement.

Consider an insulated metal or fiberglass door when replacing exterior doors. They are a better investment than wooden doors since they are much more durable, have lower maintenance needs and seal and insulate better. They also have the added advantage of offering more of a deterrent to intruders.

Most insulated door prices range from $200 to $400. One common type has a steel skin with a polyurethane foam core; they usually have a magnetic strip (similar to a refrigerator door magnetic seal) for weather-stripping. If installed correctly and, if the door is not bent, this type of door needs no further weather-stripping. The R-values of most steel and fiberglass clad entry doors range from R-5 to R-6 (not including the effects of a window.) For example: A 1-1/2 inch (3.81 cm) thick door without a window offers better than five times the insulating value of a solid wood door of the same size.

When you buy a door, it will probably be a pre-hung frame. Pre-hung doors usually come with wood or steel frames. In most cases, you will need to remove the existing door frame from the rough opening before you install a pre-hung door. The door frame must be as square as possible, so that the door seals tightly to the jamb and swings properly. It is a good idea to use expanding foam caulking to seal the new door frame to the rough opening and threshold to prevent air from getting around the door seals and into the house. You should do this before adding the interior trim.

Glass or "patio" doors, especially sliding glass doors, loose heat much faster than other types of doors because glass is a very poor insulator. Multiple layers of glass and low-e coatings improve the situation by 2 to 3 times, but it is still considerable worse than for a foam-core door.

A sliding glass door's weather-stripping is intended to reduce air infiltration, however by the sliding nature of the door's design it is impossible to stop all the air leaking around the weatherstripping while still being able to use the door. Also, after years of use, the weatherstripping wears down and air leakage increases as the door ages. If the manufacturer has made it possible to do so, replace worn weatherstripping on sliding glass doors with new weatherstripping.

However, in many of Oakland’s
commercial areas, the presence of exterior security devices such as roll-down metal doors, sliding security
gates, window bars, and barbed and razor wire fencing detract from the areas. Certain types of exterior
security devices can be detrimental to a commercial district by increasing the perception of an unsafe or
“war zone” area, degrading the appearance of and property values in the neighborhood, discouraging
potential customers and businesses, and hindering economic development.
Though that report just tries to ban barb wire, in subsequent actions they have limited use of roll-down doors too
