Why we use it
BCG treats them as both design features and technical assemblies exposed to rain, heat, humidity, and use.
Character
Material, stile width, glass proportion, threshold, and hardware can define the arrival experience.
What we look for
Water rating, construction quality, threshold design, hardware compatibility, finish durability, and lead times.
Design considerations
Scale, swing, privacy, shade, hardware finish, and adjacent lighting should be decided together.
Installation considerations
Sill pans, flashing, air sealing, shimming, drainage, and overhang protection are essential.
Common mistakes
Selecting a beautiful door without planning the threshold, exposure, or water management.
Maintenance + aging
Exterior doors need periodic adjustment, finish care, weatherstrip inspection, and threshold review.
