The Schüco ASE 80 — and its slim-line variant, the ASE 80 Panorama — is Schüco's premium residential sliding door. Where the ASE 60 covers the mainstream, the ASE 80 is what you specify when the opening is very large, the panels are very heavy, or the sightline matters more than anything else.
What makes the ASE 80 different
Three things separate the ASE 80 from the ASE 60:
- Frame depth: 80mm rather than 60mm, giving room for larger glass units and heavier hardware.
- Panel weight capacity: up to 400kg per leaf on the standard ASE 80, up to 500kg on the ASE 80 HI (heavy-industrial) variant.
- Sightline: the Panorama variant reduces the interlock to approximately 30mm — as slim as a mainstream aluminium slider gets.
The Panorama sightline
The Panorama meeting stile is the reason architects specify the ASE 80 by name. At around 30mm of visible aluminium where two panels meet, it competes directly with the slimmest sliding doors on the UK market. That slimness comes from a redesigned interlock profile and does not compromise weather sealing or security ratings — the Panorama is still tested to PAS 24.
Thermal performance
With triple glazing and warm-edge spacers, the ASE 80 Panorama achieves overall U-values down to approximately 1.0 W/m²K. That's exceptional for a large sliding door — historically, the honest trade-off with big glass was thermal loss, and the ASE 80 largely removes it.
When to specify the ASE 80
- Openings above 4.5m where panel weights rise above 250kg.
- Contemporary architecture where sightline is a primary design driver.
- South-facing large-format glazing where U-value performance matters for summer comfort as well as winter loss.
- Homes where the door will be operated daily and long-term durability is a priority.
Where the ASE 80 doesn't add value
For a straightforward 3m rear opening on a mainstream extension, the ASE 80 is overspecified. The ASE 60 costs meaningfully less and delivers the same practical experience at those sizes.
Cost expectations
Installed cost for the ASE 80 lands at approximately 40–60% above an equivalent ASE 60 configuration. For a 4m two-panel door, that's roughly £13,500–£20,000 ex-VAT installed against the ASE 60's £9,000–£13,500. The Panorama variant is at the top of that range.
Sourcing the ASE 80 locally
The ASE 80 is a specifier's system — homeowners don't typically encounter it in a showroom without asking. 5EC Aluminium covers the ASE 80 alongside comparable premium systems, and their Hertfordshire showroom is one of the places you can see the Panorama meeting stile in person before specifying it.
