Reynaers Aluminium Bifold Doors

CF 77 Aluminium Bifold Doors

The CF 77 Bifold doors are a modern and innovative design statement that can transform an ordinary room and make it a feature of the house. Concept Folding 77 bifold doors lead the way in terms of performance with reliable, easy and smooth operation that is a testament to the careful design and premium specification of every component part. The CF 77 doors also come in industry-leading maximum sizes to facilitate the design of folding doors up to a very impressive 3m in height. Bifold doors are ideal for flooding your home with natural daylight, opening up your house to the garden and letting the outside in.

Reynaers at Home bifolding doors can be designed to fit almost any space, size, or configuration using up to 8 door leaves. Due to using durable aluminium, our state-of-the art bifolding doors can be opened effortlessly and closed reliably year after year. We make it simple and effortless to fold back a wall of bifold patio door leafs and let guests wander freely between your home and garden using the CF 77 doors.

Versatile design options

Available in a number of configurations using between 2 and 8 door leaves, you can choose a design where all doors stack to the same side, or a design where some open one way and some the other. Designs with a single traffic door enable you to slip quickly and easily out into the garden, while leaving the other doors locked in place.

Specification options

The CF 77 can be specified with our standard profile or a slim-line variant, the CF 77- SL, which features a narrower door leaf profile to maximise the glass area. Both are available in four different threshold solutions:

  • High performance
  • Double weather seal
  • Low threshold
  • Flat bottom

Each threshold option gives a trade-off between weather performance and ease of passage. The high performance option offers the best air, wind and water performance but has the highest threshold step. The double weather seal solution combines good weather resistance with a lower threshold. The low threshold option can be set into the floor to meet the requirements of Building Regulations and the flat bottom solution allows easy passage with no step at all, but this is at the expense of weather-proofing.
