Improved Accessibility

Bifold doors are always a great addition to a property for accessibility, and the Schüco AS FD 75/90.HI is no exception. Its almost flat, 4 mm threshold offers great rollover capacity, and the system is adaptable to many installation situations.

Whatever your accessibility needs, the AS FD 75/90.HI can be adjusted to suit you with three different threshold options:

  • an exposed 71 mm outer frame,
  • a 15 mm threshold, and
  • the ultra-low 4 mm threshold for seamless indoor-outdoor transitions.

Quick and Simple Installation

The Schüco AS FD 75/90.HI makes bifold installation simple. Its design is as stripped-back as possible for easy fitting and a clean, minimalist look.

This system has integrated Schüco’s robust aluminium profiles into the main frame of the door, making assembly and preparation much quicker and more straightforward than in previous models.

Why Choose the Schüco AS FD 75/90.HI Door System?

Minimalist Design

The Schüco AS FD 75/90.HI boasts a simple, elegant design which brings cutting-edge minimalism to any home. It is 100% flush-fitted, with minimalist joints that allow for the optimum glass-to-frame ratio.

Quit Operations

Beyond aesthetics, the system offers Quiet Glide operation; featuring high-quality stainless steel rollers and tracks, it is one of the quietest bifold systems on the market.

Dependably Weather Resistant

Rainproofing is a common concern for UK homeowners. Even with sleek, low thresholds, Schüco bifold doors remain watertight.

You can choose to fold sashes left, right, or both, and even include a side-hung “daily access” door. The system integrates perfectly with other Schüco models for a unified architectural look.

Excellent Thermal Performance

Absolutely. The Schüco AS FD 75/90.HI is built specifically to withstand British weather. With a watertightness rating of Class 9A and advanced locking options to improve water permeability, it is one of the most weather-resistant systems available.

4. Can I have a side-hung door for daily use?

Yes, the system offers the option of a side-hung “daily access” door. This allows you to enter and exit quickly without needing to operate the entire folding sliding system.
