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.

Max. vent size

3300 × 3300 mm

Max. vent weight

600 kg

Central interlock

25 / 50 mm

Infill / glazing

up to 59 mm

Visible gap

9 mm in the slot version

Element Uw

from 0.7 W/m²K

Air permeability

class 4

Watertightness

750 Pa

Wind resistance

C3

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 official manufacturer image reveals 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.

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.

Ufthermal transmittance of the frame
Uw / Udthermal transmittance of the complete window or door
Rwsound reduction index in dB
RCburglary-resistance class
Air / Waterairtightness and driving-rain resistance
Windwind pressure and permitted deflection
