Technical Details

General characteristics

The ZENYD sliding roof system is made up of a series of aluminium profiles, designed as part of an exclusive retraction system with sections opening up to approximately two-thirds of the roof and patented under patent number xxx.

The ZENYD sliding roof system owes its excellent thermal properties to:

  • A continuous insulation profile.
  • Exterior capping of the glazing bars, with thermal break design.
  • High-performance glazing or panel sheeting.

The ZENYD sliding roof system prevents condensation thanks to its combination of thermally broken outer aluminium profiles and PVC inner jackets.

The inner jacket consists in extruded hard PVC profiles that are clasped to the roof beams and fitted with small  ribs to ensure a fixed distance to the aluminium. This creates insulating air cavities that minimise condensation and allow internal drainage.

Composition

The sliding roof

The electric sliding roof system is composed as follows: the roof panels fit into two compartments on either side of the roof beams. Each roof panel is factory manufactured and consists of a glazed (or sheeted) aluminium frame with rubber sealing for watertightness. The aluminium frame is pressed together with solid aluminium inner corner brackets by means of a hydro-pneumatic corner crimping machine. The fixed upper roof panel is placed onto the roof beams and sealed with rubber gaskets. The two other roof panels are fitted as sliding sections into the compartments of the roof beams. In open position, they slide under the fixed section.  In closed position, the specially designed bayonet sealing of the sliding frame profiles ensure perfect water and wind resistance. The bayonet sealing also forms a three-sided elevation on the sliding frame profile to provide protection against water and snow. Eight synthetic rollers on two sides of the sliding panels ensure smooth and precise guidance.

Electrically powered

The transmission is driven by an electrically powered tubular motor. The required type and quantity is determined by the manufacturer on the basis of the number of sliding roof sections, the total weight and the application. The tubular motor is entirely integrated into the wall profile. Steel-wire reinforced drive belts, which are concealed inside the roof beams, activate a pull bar that is attached to the lower sliding section. This section in turn attaches to the second sliding element and pulls it along, so that up to two-thirds of the roof can be opened. The motors are operated by a manual switch and/or by remote control, and may also be integrated into a home automation system.

Tubular motor

Operated by a bipolar asynchronous tubular motor, tested in accordance with DIN 57 700 or VDE 0700, and protected against overheating by a temperature probe.
Mains voltage: 220V - 240V [a 24V version is available for swimming pool enclosures]

Materials

Structure

The profiles are extruded from an aluminium alloy Al Mg Si 0.5 in accordance with DIN 1725. The  mechanical properties of the profiles meet the DIN 1746 standard specifications, while the dimensional tolerances are in compliance with the DIN 17615 standard.

Thermal profiles

The anti-condensation profiles are extruded from hard polyvinyl chloride (PVC). The upper temperature limit is approx. 70°C. As they are difficult to ignite, they belong to flammability class DIN 4102/Bl and B2. They are resistant to, among other things, saline solutions, diluted acids and lyes, apolar solvents, petrol, mineral oils, greases and alcohols.

Surface treatment

The aluminium profiles are enamelled (full range of RAL colours available), with warranty from APA/QUALICOAT, and the layer thickness is between  60 µ and 80 µ.

The PVC profiles are also available in all RAL colours (a limited range of nine RAL colours are mass coloured during the extrusion process; other colours through wet enamelling).

Gaskets

EPDM - butyl - neoprene or polyurethane / polyethylene with anti-shrink cord.

Brushes

Made from UV-resistant polypropylene fibres, with or without a synthetic fin, depending on the application.
