Exterior French doors are all the rage because if they’re done right, they offer superb safety and security while being Eco-friendly, lightweight, and fully insulated for increased sound deadening and climate control. The only way to create a sustainable lightweight pair of large double front doors that possess these double French doors exterior characteristics, which are also stronger than steel and guaranteed not to warp for 50 years, is with Sing Core inside.
Why is Sing Core so important for the most particular door afficionados in the world?
Granted doors with Sing Core inside may not be necessary for the masses, as standard doors available in standard door sizes are less expensive and adequate for normal everyday use. “Normal” doors move. The AWI standard for a normal 3-0 7-0 door is one-quarter-inch of movement, and the normal door industry from the door manufacturing companies, the hardware industry, and installation contractors all follow the guidelines of allowing a quarter-inch of movement without affecting normal door operation.
While you may think that glass is fairly stable, the frame which holds the glass (the French door) is subject to movement. It is the unforgiving glass which makes French doors more prone to failure, for if one corner is the slightest bit out of plum, the opposing diagonal corner will stick out like a sore thumb.
Multiply the potential for failure times two, if you have two times the doors. A double door, two doors side by side, can potentially have uncooperative movement, even in normal-sized doors of 7 ft heights, double doors can have up to one-half inch of potential movement and still not be considered officially as warped doors, yet this exceeds the efficacy of the hardware, rendering the double doors inoperable.
To further complicate the problem with door movement over the life of a door which is more likely to move more often according to changes in the environment, and even more so, if one side of the door faces the structures interior and the other is exposed to the elements. This is the recipe for the perfect door disaster. That is why interior doors cannot be used as exterior doors. Exterior doors need to be made to different specifications to maintain the same “normal” quarter-inch movement allowed.
DOUBLE FRENCH DOORS EXTERIOR
As you may have guessed, by putting all these elements together in one set of doors, you have the makings of the greatest numbers of challenges associated with a single point of entry. Incredibly special attention should be in place when considering double French doors in an exterior front door application.
While French doors may look like there is little at risk of compromising your egress point, there is much to take into consideration as each of the materials used in the construction of your exterior French doors has its own unique set of challenges as in integrates with the glass and its response to changes in environmental surroundings.
BIG DOOR PROBLEMS
The biggest problem with the door industry is with size. Normal movement of a door may be tolerable in a door that is 7 ft tall but once the door exceeds the 7 ft height, the rate of movement increases exponentially. The biggest problem with bigger doors is this increased movement which is referred to as door warp.
