Exterior and interior French doors have a number of differences, including how much they cost, how they are constructed and how they are installed. Interior French doors do not have to stand up to the elements or provide security and insulation. These doors are mostly for decorative purposes. Exterior French doors, on the other hand, serve a number of functions. Despite their design differences, interior and exterior doors provide similar decorative functions.

Functions of Exterior and Interior French Doors

Interior French doors are often used for rooms that do not have a lot of natural light from windows or skylights. The full glass doors let in light from other areas of the house. Additionally, interior French doors can partition off a room from the rest of the house without compromising an open floor plan. The doors provide some sound dampening without making a room feel claustrophobic.

Exterior French doors are typically used as patio doors. They also increase natural light into a room and make a room feel more open. Because one side is exposed to the outdoors, however, they must be constructed to withstand the elements and minimize airflow between the inside and outside of the house. Use of energy efficient glass in these doors helps prevent heating and air-conditioning loss. Proper installation with fiberglass or expanding foam insulation around the door frame also contributes to energy efficiency.
