Storm Doors
Custom Doors
Storm doors are secondary doors that fit over primary exterior doors. A storm door may save energy in two ways:
- by reducing air leakage through spaces around the existing door or..
- by creating an insulated air space between itself and the existing door, reducing heat conduction.
Storm doors can also be used to protect the main door, to reduce maintenance costs,to keep insects away and to allow natural ventilation during some seasons, which may also lower air-conditioning and energy costs.
