One of the most popular options available with today's French door market is the innovation of operable sidelights. With this unique feature you can have the best of both worlds by leaving your French door securely locked and still have the benefit of a nice breeze coming into your home.
Most of the top brands of Window and Doors have come out with their version of the French door with operable sidelights. Most are similar but have slight differences. Always consider getting the sidelights with a multi-locking system. Multi-point locking systems are very secure and will help keep the door straight and operating correctly for many years to come.
