Bi-Folding or Sliding Doors

We’ve put together the pros and cons of sliding doors versus bi fold doors for your ease. If you’ve got any questions our team are always on hand to help – just give us a call.

Sliding Doors

Pros

  • large glass panes possible
  • Wider overall width available
  • Open and close in line, not protruding
  • More traditional as a replacement
  • Up to two thirds opening
  • Narrow frame widths
  • Works well with curtains and blinds
  • Has less structural demands

Cons

  • Site conditions or location may prevent large panes being installed
  • Wide deep track (particularly on triple runners)
  • Not such a wide opening as bifolding doors
  • Doors less convenient to open and shut frequently

Bi fold doors

Pros

  • Useful for smaller doors, less than a 2 metre opening
  • Wider clearer openings possible which improves sociability between the home and the garden
  • Greater choice of configuration options
  • Separate ‘traffic door’ allows the single door to be used as a back door
  • Integral blinds readily available
  • Easy to install on sites with access difficulty
  • Wider opening when fully folded back

Cons

  • More framework, less glass
  • Intrusive when open inwards

In summary the sliding doors offer a larger glass area whilst the bi-folding doors offer a wider opening. The costs for both systems are similar ultimately it comes down to which you prefer. Viva offer you a wide choice.
