Schüco AS FD 90.HI Bifold Doors

High Insulation Aluminium Bifolds for Large Openings

The Schüco AS FD 90.HI is engineered for projects that demand exceptional thermal performance, larger glazed panels, and architectural presence. With enhanced insulation and increased structural depth, the 90HI system is ideal for luxury homes, contemporary extensions, and high-spec renovations.

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.

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.

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.

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.
