Sliding System ASS 77 PD.SI

Highly thermally insulated sliding systems based on innovative material and coating technology

The Schüco ASS 77 PD.SI (Panorama Design Super Insulated) sliding system is based on profiles made from glass fibre-reinforced plastic and, thanks to cutting-edge material and coating technology, offers an outstanding level of thermal insulation.

The system, based on glass fibre-reinforced plastic, impresses with narrow vent and frame profiles and high strength with a low dead load, perfect for implementing especially light and slimline sliding constructions with maximum light penetration.

The special advantage for the fabricator is that no additional investments in machinery are necessary, as the glass fibre-reinforced plastic profiles are delivered already processed and coated as standard. This makes it easy to begin working with an innovative material with attractive prospects for growth.

Specification texts

Schüco ASS 77 PD.SI, combined thermally insulated aluminium/GRP sliding window system with mechatronic drive
Optionally with 200 mm basic frame depth for maximum transparency and light penetration

Design features:

Outer frame
Aluminium outer frame with thermal break (PA insulating bars). The outer frame is fitted with two roller profiles which can be mitred using precision corner cleats.
The outer frames are available pre-rolled by Schüco from Schüco. The half profiles are coated first and then rolled. Possible types of coating: anodising and powder coating.

For ultra-fast delivery and fabrication times, an outer frame that has already been coated black is available from stock – the precise colour code is RAL 9005 matt.
The colour of this double-track outer frame is perfectly coordinated to adjacent building components such as glazing gaskets and insulating bars, and is therefore barely visible.

Vent profiles
The very narrow GRP vent profiles, which are covered by aluminium cover caps in the visible area, are bonded directly to the insulating glass unit in accordance with the system specifications and subsequently form a structural unit. The unit can optionally be designed with vent profiles for double and triple glazing. It must be ensured that the glass edge seal is compatible with the vent profiles. For optimum bonding, the seal must be cleaned with a surface activator.
Vent weights of up to 500 kg are possible.

Interlock section
The interlock section is designed using GRP interlock profiles (glass fibre-reinforced plastic), which are covered by aluminium cover caps in the visible area. The interlock section is sealed by means of a unique, fully-integrated interlock section seal (Schüco USP) which is mechanically triggered by means of a spring when the moveable vent reaches the closed position.
Self-adhesive centre gaskets that could become damaged in the threshold area are purposely not used in this system. The gaskets are configured in such a way that they cannot be seen by the observer.

Colour concept
In the series version, GRP profiles are also used as well as aluminium profiles in the visible area. The different material properties of aluminium and GRP may result in a different colour appearance.
A dual colour design must be used which is based on different colours for aluminium and GRP profiles. Only wet paint finishes may be used for the colour coating of glass fibre-reinforced plastics.

Profile basic depths:
Outer frame 200 mm, double-track

Vent frame 77 mm

Profile face widths: Outer frame Can be varied in accordance with installation location, concealed in the building structure.
Outer frame height of 150 mm (not visible), including the integrated mechatronic locking and drive technology.

Vent frame Fully concealed, integrated flush in the frame construction.
Face width in the centre section from 37 mm in the interlock section.

Energy: Thermal insulation: from Uw = 0.84 W/(m²K)

Maximum dimensions: Vent dimensions (W x H): up to max. 3200 mm x 3500 mm
Glass thicknesses of up to 60 mm can be used
Double and triple insulating glass is possible

Automation: Flexible selection of the operating concept: The sliding window can be operated using the following components:
External control panel – touchscreen
Wall-mounted switch
BUS system / KNX system coupling
DCS – Door Control System (Schüco building automation)

Drive and locking Concealed, profile-integrated automatic drive and locking technology.
For service and maintenance purposes, the drive installed in the vertical outer frame can be accessed at all times from the inside via the outer frame and is elegantly concealed by a cover profile.

The highest level of convenience with fully automatic operation without a dead man’s switch (with the so-called dead man’s switch, the momentary-contact switch must be held down for opening).

Fully automatic operation is available from Schüco in series and up to safety class SK 4.
Note: To be able to estimate the potential danger which could arise from a power-operated window, and to enable the requisite protective measures to be taken, a risk assessment (e.g. in accordance with VFF data sheet KB.01: 2008-12) must be undertaken at the design stage. For further information on how to proceed, see the latest version of the sliding systems order manual 1-5B.

Security: Burglar resistance to class RC 2 in accordance with DIN V ENV 1627.
Automatic load and resistance recognition by software.

Securing of the danger zones using security sensors and sensor strips (depending on the opening type).

As standard, system-based securing of the secondary closing edges and the interlock section against accidental hand trapping during closing.

Manually operated unlocking in series using a special tool from the inside.

Enhanced functions: Replacement of rollers without dismantling the moving vent.
Complete panoramic view, the vent profile is fitted flush in the outer frame.

The integrated interlock section seal is fully integrated into the profile (USP), self-adhesive gasket components are not required in the outer frame (brush seal).

Fully automatic operation by means of a conventional wall-mounted switch, touchpad, DCS module or mobile end device (iPhone) is possible.
