COMMERCIAL GLAZED
STEEL SCREENS.
Interior steel and glass screens. E/EW classification up to 60. Fixed screens to E 120. Premium commercial lobbies, glazed atria, open-plan compartmentation.
Presto is tested and classified to E and EW only — never EI. E controls integrity and flame passage; EW adds limited radiation control. Do not specify Presto where EI (integrity + insulation) is required — use Fuego Light instead.
The slim-sightline commercial system.
Presto is Forster's thinnest-profile steel screen system — built for the architectural restraint of commercial lobbies, atria, and open-plan compartmentation where a clean sightline matters as much as the classification.
E controls flame and gas passage. EW adds limited radiation control. Neither provides insulation — the unexposed face will heat up in a fire. If insulation on the unexposed face is required, specify Fuego Light (EI).
Swing Doors
Single and double leaf swing doors in Presto profile. For commercial lobby access, corridor separation, and glazed partitioning where E/EW integrity is the specified requirement.
| Product | Configuration | Classification (E/EW) | Smoke |
|---|---|---|---|
| Presto SW E 30 | Single / double leaf | E 30 | RS / S200 (opt.) |
| Presto SW EW 30 | Single / double leaf | EW 30 | RS / S200 (opt.) |
| Presto SW E 60 | Single / double leaf | E 60 | RS / S200 (opt.) |
| Presto SW EW 60 | Single / double leaf · Max | EW 60 | RS / S200 (opt.) |
Presto swing doors are classified to a maximum of E 60 / EW 60. Presto is never EI rated — if insulation on the unexposed face is required, specify Fuego Light.
Fixed Screens
Non-opening Presto screens. The only Presto configuration that achieves E 120.
| Product | Configuration | Classification (E/EW) | Smoke |
|---|---|---|---|
| Presto FS E 30 | Fixed screen | E 30 | RS / S200 (opt.) |
| Presto FS EW 30 | Fixed screen | EW 30 | RS / S200 (opt.) |
| Presto FS E 60 | Fixed screen | E 60 | RS / S200 (opt.) |
| Presto FS EW 60 | Fixed screen | EW 60 | RS / S200 (opt.) |
| Presto FS E 120 | Fixed screen · Flagship | E 120 | RS / S200 (opt.) |
E 120 in Presto is achieved on fixed screens only. Do not specify E 120 on any swing-door configuration. Presto remains E/EW rated across all configurations — never EI.
Smoke Control Screens
Presto screens configured for smoke control rather than fire integrity. Used for smoke compartmentation in atria, stairwells, and open-plan office floorplates.
| Product | Configuration | Smoke Classification | Leakage (S200) |
|---|---|---|---|
| Presto SC RS | Smoke control screen | RS | Tested at 200 °C |
| Presto SC S200 | Smoke control screen | S200 | Tested at 200 °C |
Smoke classifications (RS / S200) are independent of fire integrity. Where both are required, specify a Presto E/EW configuration with the RS/S200 smoke option selected.
Presto system parameters.
Profile dimensions, glazing build-up, and ironmongery confirmed per project against the Forster Presto system manual. Presto delivers E/EW integrity — not EI insulation.

Glazing and frame integration.
Presto is installed per the Forster system manual. Glass is supplied and glazed to the Forster specification — the E/EW 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. Presto is an interior-only system. Smoke-seal engagement must be verified at commissioning where the RS/S200 option has been specified.

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.
