1. Sliding Doors
Sliding doors are extremely efficient and elegant when initially installed. Compromise can come not long after installation due to warping, bending or twisting. To prevent the sliding doors from warping, doors can be manufactured from heavy materials, like steel, which is not high precision (due to welding), certainly not Eco-friendly and the excess weight causes problems for the hardware due to added stress because of the added weight.
2. Pocket Doors
Pocket doors are not unlike sliding doors, except for the fact that they are retracted or hidden within a recess. This makes it even more important that your pocket door remain straight and true without warping. A warped pocket door is pretty much useless and the cost of maintenance on a pocket door is increased because the mechanisms are buried deep within a wall (or other structure material) increasing the expense of repairs over time.
3. Bi fold Doors
Bi fold doors consist of two (or more) door panels connected by hinges, so that they can fold together flatly. Expensive heavy duty piano hinges can be used to maintain the integrity of the bi fold door panel if the individual panels are narrow. When using larger sized door panels, even full length hinges cannot keep the door from warping.
4. Oversized Doors
Large oversized door represent the biggest challenge for architects, contractors, designers and millworks. End users embrace high ticket prices associated with huge doors but also desire a high level of performance when investing in such a project. The truth is, not long after installation (especially if the door is over 7 ft. tall) the door fails to secure correctly due to warping. Unfortunately, this affects all types of doors, such as wood doors, fiberglass or FRP doors, MDF and LVL doors, even metal doors; like aluminum doors and steel doors.
5. Wood Panel Doors
Wood panel doors attract deficiencies based on the natural nature of the wood itself. Wood is a living resource that naturally acclimates to its surroundings according to temperature, moisture and stress. While natural wood is extremely attractive and highly sought after, left to its own devices, it will fail. People who love wood have come to accept its limitations as a trade off for its beauty and elegance in wood doors. Beautiful wood doors demand regular maintenance to combat regular warping issues.
6. French Doors
French doors are wood doors or wood panel doors (that could be manufactured in a stile and rail design) that hosts a large portion that is cut out for window lites offering an extended view of the landscape or other visual features that may exist on the other side of the door. In this instance, heavy glass may be strong enough to keep the wood edges straight for a period of time, but results in a heavy door. And stile and rail design is not very secure where the joints are connected.
7. Exterior Steel Doors
Whether for security purposes, visual impact or other reasons, exterior steel doors can resist warping, especially if they are finely honed solid steel. More common in contemporary steel doors are solid steel sheets with interior bracing that is of welded construction. This is not very efficient, does not make a highly precision door, though it does eliminate much of the weight of a solid steel door. It stands to reason, if an interior weld is broken due to impact or heavy use, the door will fail.
8. Pivot Door
Growing in popularity – especially amongst high end homes and commercial installations – pivot doors are the most sought after contemporary architectural design in entry doors today, though this elegant fashion statement does come at a price. These modern pivot doors are often large oversized doors (we already know these are problematic) and they must remain perfectly flat and balanced to operate and seal correctly. Until now, the heavy duty hardware required for pivot doors to function properly could amount to as much as half of the cost of the pivot door.
9. Modern Barn Door
Modern barn doors have a pleasing visual impact that is growing amongst designers and homeowners across America. The modern barn door is just as it sounds, a wood door plank suspended by hanging door hardware above that slides back and forth, just like a traditional sliding barn door. You see modern barn doors appearing mostly in interior door designs though are featured in exterior doors used in garages and warehouses, more traditionally like a common barn door. Again, though a modern barn door could be made of most any type of flat plank material, wood is most common and carries the caveats associated with natural wood.
10. Carriage Door
Carriage doors are the most high end garage doors in use today. In fact, they used to be the only style or doors used in early American architecture but their popularity faded due to the expensive upkeep, maintenance and repairs necessary to keep them in service over time. When inexpensive overhead doors became readily available, the carriage doors were replaced by the less troublesome style of overhead door. Though they are still very popular amongst the most expensive homes in the USA.
