Schüco AS FD 90.HI Bifold Doors – High-Insulation Aluminium Systems for Large Openings

The Schüco AS FD 90.HI bifold doors are designed for large-scale glazing projects where thermal performance, structural strength, and premium aesthetics are essential.

At SlideorFold, we supply and install Schüco 90HI bifold doors across Birmingham, the West Midlands, London, and the Home Counties, delivering high-performance aluminium systems tailored to luxury homes, extensions, and architectural builds.

What Are Schüco AS FD 90.HI Bifold Doors?

The Schüco AS FD 90.HI is a high-insulation aluminium bifold door system engineered for wider openings and improved thermal efficiency compared to standard bifold systems such as the AS FD 75.

With a deeper 90mm profile and advanced thermal break technology, it offers enhanced energy performance while supporting larger glass panels and minimal sightlines.

Designed for Larger, More Impressive Openings

Unlike standard bifold systems, the AS FD 90HI supports panels up to 3.5m high × 1.5m wide, making it perfect for expansive openings and statement glazing.

Its 90mm profile provides additional strength, allowing:

  • Bigger glass areas

  • Fewer sightlines

  • Greater structural integrity

This is bifolding at architectural scale.

 

Premium Engineering & Security

  • PAS24 / RC2 burglar resistance

  • Secured by Design approved

  • Multi-point locking

  • Stainless steel roller systems

It combines strength and security without compromising its refined appearance.

Enhanced Thermal Performance

The “HI” stands for High Insulation — and that’s where this system stands apart.

  • U-value from 1.3 W/m²K

  • Advanced thermal break technology

  • Double or triple glazing options

  • Designed for energy-conscious builds

The AS FD 90HI is particularly suited for homeowners prioritising energy efficiency and long-term performance.

Tailored Luxury, Built Around Your Home

Available in any RAL colour, with flush threshold options and adjustable frame jambs, the system integrates seamlessly into both modern and heritage-style builds. Optional Gem & Morley blinds can be integrated for added privacy and solar control.

Installed by approved Schüco partner fabricators, every system is precision manufactured in the UK and installed to exacting standards.

Is the AS FD 90HI Right for You?

Choose this system if you want:

✔ Larger-than-average openings
✔ Superior insulation
✔ Premium architectural finish
✔ A high-spec, long-term investment

If your project is more standard residential scale, the AS FD 75 may be more suitable. If performance and scale matter — the 90HI is the upgrade.

Design & Appearance

Schüco AS FD 90.HI bifold doors are a high-performance aluminium door system designed for large openings and enhanced thermal efficiency. The “HI” stands for High Insulation, meaning the system uses advanced thermal break technology to reduce heat loss while still allowing for large glass panels and slim sightlines.

Security & Performance

The AS FD 90.HI is designed with advanced thermal insulation, achieving excellent U-values that help retain heat, reduce energy bills, and improve overall comfort in your home.
