Description
Exterior folding door offers greater flexibility to its users. It enables us to use weather conditions to our advantage and virtually eliminate the barrier between the interior space and its surroundings. Such door can perfectly combine the interior space (home, café, restaurant) with the terrace or the outside area that is used seasonally. With its excellent technical parameters, MB-86 FOLD LINE HD is a very convenient solution that enables the fabrication of large-dimension structures. Folding door can be opened both outwards and inwards and its leaves can be freely configured. It’s a modern product, designed to meet the high demands of users, architects and owners.
The ALUPROF MB-86 FOLD LINE HD is a solution which provides plenty of comfort in its daily use. At the same time, it not only features high technical parameters, but also makes it possible to create large-scale structures. The bifold doors can open outwards or inwards and the panels can be configured as desired. This state-of-the-art product is designed to meet the exhaustive demands of users, architects and developers alike.
DESIGN VARIANTS
Next to the functional design, the CF 77 is supplemented with a Slim-Line variant, the CF 77-SL, featuring a narrower visible width. Both
designs are available in four different door sill solutions:
High Performance, Double Weather Seal, Low Threshold, and Flat Bottom Solution.
The High Performance option offers maximum performance in terms of air, wind, and water resistance. The Double Weather Seal solution combines good air, wind, and water resistance with a decreased threshold and is well suited for renovation projects. The Low Threshold option offers a rise of only 3/4 inches. Finally, the Flat Bottom solution allows for easy passage and maximum convenience for high traffic.

We have used SBW on several occasions over the years and always found their services very good, hence I’m a repeat customer. I’ve had bifold and sliding patio doors, front door, other exterior doors and replacement double glazing windows. Quality products, great customer service and aftercare.

Was very impressed both by the service and the product. After a bad experience with a previous window company, which you could feel the draft coming through after one month of instalation, I was skeptical to try different company. I am thrilled I found SBW GROUP. I had my windows done in April 2024 and the quality is above my expectations. The installation team was very organised, professional and considerate and we are very pleased with the results. Highly recommend them.
