Siegenia | Portal | Sliding Windows and Doors System

The parallel sliding system PORTAL ECO SLIDE COMFORT combines the smooth-running and intuitive operation of a sliding solution with the benefits of turn-and-tilt hardware. It is based on the wraparound sash hardware on the tried-and-tested TITAN central locking gear and simultaneously provides reliable compression and burglar resistance up to RC2. Its efficient production and availability for a wide range of PVC profile systems make it an all-rounder.
Not much room, but a lot of space: versatile and space-saving in use.

As a sliding window or sliding door with only 45 mm passage height, it creates more interior space. Whether it is used in the bathroom or in the kitchen. Whether it is used in hotels, offices or schools. The PORTAL ECO SLIDE CO brings more freedom of design into residential and commercial buildings and adapts perfectly to every space.

The PORTAL FS fold and slide system is designed for large-format openings, delivering expansive widths and maximum architectural flexibility. Suitable for timber and PVC profiles, the system supports sash weights of up to 80kg per sash and configurations of up to seven elements.

With opening widths of up to 6.3 metres, PORTAL FS creates seamless indoor–outdoor transitions while maintaining smooth and reliable operation. High-quality surface technology ensures durability, including suitability for external applications.

The system also offers fabrication efficiency, flexible configuration options and cost-effective processing for manufacturers.

The PORTAL HS 400 lift & slide system is engineered for large-scale architectural openings, enabling expansive glazed elements with exceptional ease of operation. Developed by Siegenia, the system supports sash weights between 300kg and 400kg while maintaining smooth and controlled sliding performance.

With opening widths of up to 12 metres and total system widths reaching 19.8 metres, PORTAL HS 400 allows walls to visually disappear — maximising natural light, spatial flow and indoor–outdoor integration.

The HS 400 compact bogie wheels feature optimised, self-aligning load distribution across eight rollers, ensuring effortless movement, reduced wear and long-term durability. The low-profile wheel design also enables slimmer profiles, enhancing light penetration and energy efficiency. By eliminating the need for tandem solutions in the 300–400kg range, the system reduces assembly time and improves production efficiency.

For timber and PVC profiles with sash weights of up to 150 kg.
The economical solution for upgrading conventional sliding elements.

The PORTAL CS allows you to convert basic sliding doors and windows into high-quality sliding elements using an economical system. Height-adjustable bogie wheels on ball bearings mean that timber or PVC sashes with weights of up to 80 or 150 kg can be moved with ease. Up to four special-steel locking hooks and an integrated anti-lift device provide the necessary security. 

• Economical and low-maintenance sliding window system
• Convenient operation via different handles
• Especially smooth-running due to durable rollers on ball bearings
• Two custom-fit versions for timber and PVC profiles: PORTAL CS 80 and PORTAL CS 150 for sash weights of 80 or 150 kg

Force-controlled providing compression and reliability: Innovative guiding and locking elements.

They guide the sash at all four corners precisely and dampened into its closing position or intuitively trigger the night vent. The special sealing system consists of up to two continuous, circumferential sealing levels and the necessary sealing forces are force-controlled from the handle via the gear and transferred to the two locking hooks.

• High compression due to guiding and locking elements in each corner
• Intuitive, force-controlled operation with night vent function
• High resistance to misuse: Also ideal for changing user groups
• Wear-resistant locking bolts and hooks mounted on ball bearings made of high-quality cast brass
• PVC stops absorb the impact noise
• Integrated height adjustment for optimised adjustment options

The 16 mm eurogroove is identical to that used in turn-and-tilt windows – no modifications required

Sturdy and reliable.

As safe and gentle as a modern kitchen drawer.

There is a safe solution for the simple operation of sliding systems: The innovative SOFT CLOSE damper which can be invisibly integrated into the sash. This brakes the sash gently just before the end position and then pulls it shut automatically. This minimises any risk of injury in the case of improper operation and precludes any material damage.

• Prevents damage and injury caused by improper operation
• Simple and intuitive operation: Faulty switching is excluded
• Completely new sliding feeling through maximum smooth operation
• Easy to adjust
• Maintenance-free thanks to oil-lubricated gas pressure spring
• Perfect design: Fully concealed solution

Time-saving and cost-effective in production

The wraparound sash hardware is based on the TITAN central locking gear and only needs a few additional components. This means it ensures efficient processes from lean warehousing processes to easy assembly. The installation is quick and the hardware adjustment is as easy as with turn-and-tilt hardware.

In its design-oriented version, the PORTAL ECO SLIDE COMFORT is equipped with locking parts without visible screwing as well as continuous locking rails on the locking side and in the centre part. An individualised logoclip can be pre-mounted on the strikers on the locking side.
