ABOUT FOLDING DOORS

 

Folding doors may be made of wood, molded wood, fiberglass, steel, or glass. They range in size from the largest glass folding doors, which open the whole side of a room to the outside, to small folding doors for closets, laundries, and storage areas. Specialist types of folding door include acoustic doors, multifold doors, glass doors, interior doors, exterior doors, and accordion doors. Accordion folding doors are made of narrow vertical panels, requiring less space for storage when folded.


 

CHOOSING THE BEST TYPE

 

Choosing internal doors

 

Internal folding doors are mostly used for bedroom closets, or for kitchen storage areas. They have the advantage over normal hinged doors that they take up less space within the room. They have the advantage over sliding doors that the whole opening can be opened at once; by contrast with sliding doors less than half the opening can be opened at once. The panels may be made of solid timber, or medium density fiberboard. The timber may be stained or painted, and the medium density fiberboard may be painted or finished in wood veneer. We would advise keeping the design of the door simple, either with a plain flat surface or with a simple Shaker-style framing. Complicated decorative grooves are liable to look very fussy.

 

Another type, sometimes used between rooms, is the accordion door. Accordion doors are made up of rigid vertical slats, connected together to form pleated structure covered in a flexible vinyl material. They are so called because they resemble the folding body of an accordion musical instrument. Their advantage is that they take up very little space when opened, and require more effort to open or close compared to a conventional hinged door. Their sound insulation and draught protection is poor.

 

Choosing external doors

 

External folding doors, which may be half or fully glazed, provide openings between living rooms and the yard or patio. They are made up of vertical panels which are hinged together in concertina fashion. They can open inward or outward. You should base your choice of inward our outward opening on where there is most space to accommodate the opened doors. The great advantage of these doors compared to sliding doors is that they enable the whole opening to be opened at one time. This allows the space and air to flow freely between the room and the outside. By contrast sliding doors normally only allow half the opening to the opened at any time.

 

The four main materials used for external doors are timber, vinyl, aluminum and aluminum-faced timber. Timber looks attractive, but requires external maintenance, and is liable to warp or twist, particularly with changes in temperature or humidity. Vinyl is practical, but requires rather thick frames and can look rather cheap. White vinyl is liable to yellow over time, which is an argument for using wood-look vinyl. Aluminum is a very practical material for external folding doors. It looks rather cheap if left in its bare form, but it is available in a very wide range of power-coated colors. These are very long lasting and do not require maintenance.

 

A very attractive option, although it is relatively expensive, is aluminum-clad wood. The external face is in aluminum, available in a very wide range of powder-coated colors; the internal face is natural wood, giving a warm and attractive internal appearance.
