Glazed walls and façades
The VISS mullion-transom systems: a thermally insulated façade with a Passivhaus certificate, a version without a load-bearing structure, structural glazing and a fire-resistant façade.
A curtain wall is a load-bearing structure in its own right, not an enlarged window. The mullions and transoms take the wind load and the weight of the glazing and transfer them to the structure of the building, while the glass is merely infill. Steel makes this grid possible with sightlines of 50 and 60 mm, at spans where other materials would call for far thicker profiles. Only the façade systems themselves are here; the doors and windows fitted into them have their own pages.

Thermally insulated façades
Jansen VISS — façade
Jansen · Thermally insulated façades
A highly insulated façade, with a Passivhaus certificate.

Jansen VISS Basic — façade
Jansen · Thermally insulated façades
A façade with no load-bearing structure of its own, on standard profiles.
The difference from VISS is the structure: here the mullions are not system profiles but ordinary hollow or IPE sections, onto which only the sealing and glass-retaining parts are fitted. Where the project does not call for maximum thermal performance, it is the version with the best result-to-cost ratio.

Fire-resistant façades
Jansen VISS Fire — EI30, EI60 and EI90 façade
Jansen · Fire-resistant façades
A compartmentation façade, in three fire resistance classes.
It is the façade that holds fire. Classes EI30, EI60 and EI90 are not finish options but separately tested systems, with different infill thicknesses — which is why the class is settled from the fire safety strategy, before design begins.
Technical characteristics
- Fire resistance
- EI30, EI60 and EI90; tested to EN 1364-1 and EN 1364-3
- Classification
- to EN 13501-2, EN 15254-4 and EN 15254-6
- Sightline
- 50 and 60 mm

- Load-bearing structures: VISS system profiles, high-strength profiles and Linea design profiles in EI30
- Doors can be integrated into the façade
- Glazing dimensions of over 4.3 m high in EI30 and widths of over 3 m, with no additional structural measures
Jansen VISS Fire — EI30 RC2/3 façade
Jansen · Fire-resistant façades
EI30 compartmentation and RC2 or RC3 burglar resistance, in one system.
Until now, a façade that had to resist both fire and forced entry called for two systems superimposed. Here the two functions are tested together: EI30 for thirty minutes of fire resistance, plus RC2 or RC3 for an attempt with simple tools and with heavy tools respectively.
Technical characteristics
- Fire resistance
- EI30, tested to EN 1364-1 and EN 1364-3
- Classification
- to EN 13501-2
- Burglar resistance
- RC2 and RC3
- Sightline
- 50 and 60 mm
- Construction depth
- 50 – 280 mm in the basic version
- Infill thickness
- 19 – 49 mm
- Uf value
- from 1.3 W/m²K
- Watertightness
- class RE 1200
- Air permeability
- class AE
- Wind resistance
- class 2 kN/m²
- Impact resistance
- class E5/I5
- Approvals
- AbP P-2020/001 for glazing protecting against falling; AbZ Z-14.4-465 for the clamped joint and Z-14.4-467 for the mullion-transom joint
- Product standard
- EN 13830, CE marking
Where it is used
Residential buildings, office buildings and public buildings with a dual requirement: fire and burglary.
Performance and equipment
- It combines fire protection class EI30, which provides 30 minutes of fire resistance, with burglar resistance classes RC2 and RC3
- RC2 covers an attempt with simple tools, RC3 with heavy tools
- Developed for the requirements of modern projects: robust and flexible, from residential buildings to office and public buildings
The values above are those published by Jansen for that system. The performance of an installed element is established on the configuration actually ordered and on the corresponding test certificate. The renders and section drawings belong to Jansen AG and are used to identify the system.
