French Door Dimensions
We at The Maiman Company believe in the importance of flexibility, allowing you to choose the door you want. The charts below set out our minimum dimensions for our French doors as well as the maximum dimensions that will secure a UL- or Warnock Hersey-sponsored fire rating. In addition, we can usually construct doors that surpass the dimensions listed below and give them Construction Label Only (CLO) tags.
The Maiman Company has set the standard in fire-rated French doors. Our 20-minute doors feature our unique all-wood true divided lite construction. This means that each lite is an individual piece of glass framed by pieces of wood instead of one large piece of glass with a wooden "grate" sitting on each side of the glass. The true divided lite construction has many advantages, but the primary reason people choose it is for its high quality finished look. All standard sticking options and lited elevations are available in 20-minute fire-ratings.
