For large sliders, glazing is not only about Ug: weight, solar factor, heat treatment and laminated layers directly affect hardware and installation.
Aluron / Large-format HST doors
AS 178HS Modern
A new-generation Aluron lift-slide platform focused on faster prefabrication and installation. The frame can be transported in parts and assembled on site, with a threshold-free slotted option available.
VERIFIED PARAMETERS
Large format with an installation strategy.
Modern retains large allowable sizes while simplifying fabrication and logistics. This is especially useful where transporting a fully assembled frame is difficult.

AS 178HS Modern is designed for large elements, but practical geometry depends on track layout, glazing, panels and assembly method. We engineer the actual unit rather than an abstract system.
PROFILE CROSS-SECTION
AS 178HS Modern profile geometry in detail.
This image shows the system's profile geometry, chambers, thermal breaks and glazing zones. The final junction is selected for the opening scheme, glass build-up, dimensions and project loads.
DESIGN & ASSEMBLY
Architecture that can be easier to deliver and assemble.
01
Schemes A, C, G, K
02
ULTRA variant with 25 mm central mullion
03
All-glass internal and external corners
04
Low warm threshold, linear drainage and automation options
LOGISTICS
A knock-down frame can solve access constraints.
For large openings delivery is often as complex as fabrication. Site assembly changes transport, lifting and installation-sequence requirements.
01
Delivery
Package dimensions, site access and unloading zones are checked in advance.
02
Assembly
Frame geometry is laser-checked before heavy vents are installed.
03
Threshold
The slot solution requires precise coordination of floors, channel drainage and waterproofing.
BIFORIUM / PRACTICE
A system only works as a whole with glass, hardware and installation.
Threshold support, finished-floor level and linear drainage must be coordinated before the unit is ordered.
Open engineering details ↗Manual or motorised hardware is selected after checking the real sash weight and operating scenario.
Threshold support, finished-floor level and linear drainage must be coordinated before the unit is ordered.
FAQ / SPECIFICATION
Questions to close before specification.
Can the system be selected only from catalogue performance?
No. Published values help shortlist options, but the finished element still has to be checked for size, glazing, weight, hardware, loads and installation detail.
Does every opening need the same glazing build-up?
Not necessarily. A south-facing elevation, a bedroom near traffic, a large fixed pane and an entrance leaf can require different glazing within the same project.
When should the installation detail be coordinated?
Before the final order. Finished-floor level, insulation, waterproofing, structural support and drainage can change the frame, threshold or final manufacturing size.
HOW TO READ THE DATA
Six values that shape the result.
A catalogue maximum is not the rating of every fabricated element. Classes depend on size, opening scheme, glazing, hardware and the tested configuration.
