Licensed Fabricator

DFM fabricates the Forster Fuego Light and Unico systems under annual-audit licence from Forster AG (Switzerland). Forster AG holds all test evidence, Declarations of Performance, and CE certification for these systems.

Forster Systems

Two systems. Different jobs.

Fuego Light handles interior fire compartmentation in steel and glass. Unico extends the same architectural language to exterior thermally-broken openings.

Fuego Light

Interior Fire Glazing

EI 30 / 60 / 90 · fixed screens to EI 120 · Sa/S200

Side-hung doors, fixed screens, and single-track sliding doors. Used for compartmentation, atrium separation, and glazed lobbies where daylight and a fire line must coexist.

  • Side-hung · EI 30 / 60 / 90
  • Fixed screens · EI 30 / 60 / 90 / 120
  • Sliding · EI 30
  • RC3 + fire combined available
Unico

Exterior Thermally Broken

EI 30 / EW 30 · Uw down to 0.9 W/m²K

Full thermal break in 100% steel — no synthetic insulators. Used for exterior entrances and façade openings where both thermal performance and fire resistance are required.

  • EI 30 · EW 30
  • Uw down to 0.9 W/m²K
  • 100% steel — no synthetic insulators
  • Exterior applications
Fuego Light · Configuration 01

Side-hung Doors

Single and double leaf side-hung fire doors in Fuego Light steel profile. For compartment doors, corridor separation, and glazed lobbies.

Product Configuration Fire Classification Smoke
Fuego Light SH 30 Single / double leaf EI 30 Sa / S200
Fuego Light SH 60 Single / double leaf EI 60 Sa / S200
Fuego Light SH 90 Single / double leaf · Max EI 90 Sa / S200

Side-hung Fuego Light doors are classified to a maximum of EI 90. EI 120 is not available as a side-hung door configuration — see Fixed Glazed Screens below for EI 120 performance. RC3 burglar resistance can be combined with any side-hung fire rating.

Fuego Light · Configuration 02

Fixed Glazed Screens

Non-opening glazed fire screens in Fuego Light profile. The only Fuego Light configuration that achieves EI 120.

Product Configuration Fire Classification Smoke
Fuego Light FS 30 Fixed screen EI 30 Sa / S200
Fuego Light FS 60 Fixed screen EI 60 Sa / S200
Fuego Light FS 90 Fixed screen EI 90 Sa / S200
Fuego Light FS 120 Fixed screen · Flagship EI 120 Sa / S200

EI 120 in Fuego Light is achieved on fixed screens only. A fixed screen is a glazed assembly with no opening leaf — do not specify EI 120 on any side-hung or sliding door configuration.

Fuego Light · Configuration 03

Sliding Doors

Single-track sliding fire doors in Fuego Light profile. Interior applications where the opening plane must stay clear.

Product Configuration Fire Classification Smoke
Fuego Light SL 30 Single track sliding EI 30 Sa / S200

Sliding Fuego Light doors are classified at EI 30 only. For higher fire ratings in a sliding configuration, see Sliding Gates (SG 60 / SG 90).

Forster Unico · Configuration 04

Thermally Broken Doors

Exterior steel-and-glass doors with full thermal break. 100% steel profile — no synthetic insulators — achieving Uw values down to 0.9 W/m²K with EI 30 fire classification.

Product Configuration Fire / Radiation Thermal (Uw)
Unico EI 30 Exterior · Thermally broken EI 30 Down to 0.9 W/m²K
Unico EW 30 Exterior · Thermally broken EW 30 Down to 0.9 W/m²K

Unico is Forster's thermally-broken system — all-steel construction with no polyamide or plastic insulators. Designed for exterior applications where both fire performance and Part L thermal compliance are required.

Installation

Glazing and frame integration.

Fuego Light and Unico are installed per the Forster system manual. Glass is supplied and glazed to the Forster specification — the classification depends on the correct glass, gasket, and seal build-up being delivered together. Substituting any component voids the classification.

Supported substrates: masonry, concrete, structural steel, and engineered timber. Unico exterior installations require the thermal-break continuity to be maintained across the frame-to-substrate interface, with weather-sealing per the Forster detail.

  • 01

    Verify the opening

    Check structural opening against the Forster system field of application and the project-specific fabrication schedule.

  • 02

    Frame installation

    Install Forster profile frame with approved anchors. Plumb, square, and packed to Forster tolerance. Maintain thermal break continuity on Unico.

  • 03

    Glazing

    Glaze with the specified Forster fire glass, gaskets, and intumescent seals. No substitution. Handle per Forster manual to avoid edge damage.

  • 04

    Commission and record

    Test operation, verify smoke seal engagement, and record the Forster DoP reference and installer sign-off for the project file.

CE Certification · Forster Systems

Fuego Light and Unico CE certification is held by Forster AG (Switzerland). DFM fabricates these systems under annual-audit licence and supplies Forster-issued test evidence, Declarations of Performance, and CE documentation with each order.

This is distinct from the DFM steel ranges, which are certified under ETA-22/0324 issued by OiB Vienna. Contact us to confirm scope and documentation before specifying.
