Visofold Folding Door System

The thermally broken folding door system is designed to allow for maximum thoroughfare through an opening. The system is built up using a frame in which moveable parts or elements are placed In such a way that it is possible to fold up the elements to the left or right. These elements or sashes are supported and hinged to a mullion. At the bottom, the mullion is supported by a roller mechanism which slides along the cill profile while at the top, the mullion is guided by another roller mechanism. There are many possible combinations of elements and opening sashes.

  • We work on many different types of projects including Folding doors, windows and conservatories.

    On each project, we make an initial free of charge survey, prepare a detailed quotation and on acceptance, immediately start the manufacture. Many of our clients have very specific requirements and each job is unique. Many want the work completed very quickly and we do our best to accomodate all needs.

    On one project a client needed 4 sets of Folding doors across wide spans and completed by a specific date which was within only one month in time for a family barbeque. No problem, the job was completed on time to the clients precise requirements! See our client testimonials...

    Our own dedicated installers are highly trained and will ensure the job runs smoothly and with the least inconvenience to you. We also ensure that the finishing and surrounds are repaired or made good to the highest standard.
