Retrofit Storm Door

Adding a storm door can be effective if your existing door is old but still in good condition. The maximum benefit is achieved for older doors that need increased efficiency to prevent excessive energy loss. Additionally, is you live in an environment that has frequent storms or where your door is exposed to extreme weather elements, it is recommended to install a storm door to protect the more vulnerable inner door. However, for a newer, insulated door is not generally worth the expense, you won't save much more energy. A glass storm door could help trap heat against an entry door. Yet, it might cause damage if the exterior door gets more than a few hours of direct sun each day. In this situation, having a low-e glass will reduce the heat gained and therefore, it is important to consider what your specific requirements.   Some smart doors also have additional features such as protective safety locks that can provide enhanced security to your home. 

In retrofit programs to date, exterior wall insulation improvements were uncommon, even though walls often account for 25 to 35 percent of the heat loss of a typical existing home.
