Pyrocover 100 Cover Plate – RAL 9006 is a pressed-steel louvred cover designed to provide a neat, protective and visually finished face over a compatible Pyrogrille 100 intumescent air-transfer grille.
The cover plate is face-fixed to the door, wall or duct surface around the installed air-transfer grille.
Its angled louvres help conceal the exposed black intumescent grille while continuing to permit airflow through the opening during normal building use.
The current stocked range is supplied in a fixed:
RAL 9006 White Aluminium finish
and is available in thirteen square and rectangular sizes.
The Pyrocover 100 is used as a decorative and protective facing over a compatible intumescent air-transfer grille.
It can help:
It may be fitted to suitable:
The complete application must follow the relevant fire-test evidence, assessment and building design.
The Pyrocover 100 is principally intended for use with a compatible Pyrogrille 100 intumescent air-transfer grille.
The Pyrogrille 100 remains open during ordinary conditions to allow air movement.
When exposed to fire conditions, its graphite-based intumescent material expands and closes the internal ventilation paths.
The Pyrocover 100 remains on the visible face of the installation and provides the finished louvred appearance.
The two products perform different functions:
The cover plate must not be used as a substitute for the intumescent air-transfer grille.
The Pyrocover 100 does not independently restore the fire resistance of an aperture.
Any fire performance belongs to the complete tested or assessed installation, including:
Do not assign an FD30, FD60 or FD120 rating to the cover plate alone.
An intumescent air-transfer grille installed through a door or wall commonly has a visible face on both sides.
Where the specification requires both faces to be covered, install:
The cover plates are sold individually rather than as an automatic pair.
Confirm the required quantity before ordering.
The pressed-steel cover incorporates angled ventilation louvres.
The louvres allow air to pass through the plate while helping limit a direct line of sight through the opening.
This can provide:
The cover is not a security grille and should not be treated as providing resistance to forced entry.
The Pyrocover 100 must remain unobstructed so air can pass through its louvres.
Final airflow depends on:
The cover plate can introduce additional airflow resistance and should be included within the ventilation design.
Do not use the nominal face dimensions as a substitute for a calculated free-area or pressure-drop requirement.
The stocked cover plates have a fixed:
RAL 9006 White Aluminium finish
RAL 9006 has a silver or metallic aluminium appearance and is commonly used for ventilation grilles, architectural metalwork and associated building components.
The finish can coordinate with:
Appearance can vary according to lighting, coating texture and the surrounding materials.
The cover grille is formed from pressed steel to provide a rigid face-mounted component.
The steel construction helps:
The cover should remain flat and undistorted.
Bent or damaged louvres can affect appearance and airflow.
Pressed-steel decorative cover grilles are normally intended for dry internal locations.
Do not assume that the standard RAL 9006 finish is suitable for:
A suitable weather-resistant or moisture-resistant alternative may be required for these environments.
The Pyrocover 100 remains open during normal conditions and does not independently prevent cold smoke from passing through the opening.
It must not be described as a cold-smoke seal.
Where the door requires smoke containment, confirm that:
A standard open cover plate and intumescent grille should not automatically be fitted to a fire-and-smoke door.
The cover-plate size should be selected to suit the intended grille and aperture arrangement.
The stocked nominal sizes are:
The stated dimensions should be treated as the nominal grille or opening size.
The external face dimensions may be larger because of the surrounding mounting flange.
Confirm the overall dimensions before checking:
The stocked Pyrocover 100 range includes sizes that are not identical to every stocked 25mm-thick Pyrogrille 100 option.
For example, the cover range includes 300 × 250mm, while some grille ranges use different nearby rectangular dimensions.
Do not select the cover plate solely because its dimensions appear similar.
Confirm compatibility using:
The stocked square covers are:
The stocked rectangular covers are:
Subject to the complete specification, Pyrocover 100 plates may be used on:
Before ordering, confirm:
The Pyrocover 100 should not be used as a replacement for an intumescent air-transfer grille or relied upon as an independent fire-protection product.

A typical through-door or through-wall installation may require:
| Installation Requirement | Typical Cover Quantity |
|---|---|
| Cover on one visible face only | One plate |
| Matching covers on both faces | Two plates |
The applicable test evidence and project specification determine whether covers are required on one or both faces.
The cover plate is not the active intumescent fire-protection component.
Published fire performance applies to the complete system, including:
The louvres remain open during ordinary ambient conditions.
The cover does not independently prevent cold-smoke passage.
Do not install an open transfer-air system in a smoke-control door unless current test or assessment evidence permits it.
The cover plate should be included within any ventilation free-area and pressure-drop calculations.
Do not:
Store the cover plates:
Inspect the installed covers periodically.
Check for:
Clean the cover using a soft cloth or suitable vacuum attachment.
Do not use abrasive cleaning tools that could damage the RAL 9006 finish.
Pyrocover 100 Cover Plates are face-fixed centrally over a compatible intumescent air-transfer grille.
Where the installation requires covers on both sides of a door or wall, fit one plate to each face.
The cover must remain securely fixed without obstructing the grille’s airflow or damaging the underlying fire-resisting construction.
Confirm:
Do not use the cover plate to conceal an incorrectly installed or damaged intumescent grille.
Before fitting the cover, inspect the underlying air-transfer grille.
Confirm that:
Correct any defect before covering the grille.
Check the Pyrocover product code against the installed grille and aperture.
Confirm:
Do not force an incorrectly sized cover over the grille.
Determine whether the project requires:
Where two covers are required, check that both have:
Inspect the angled louvres and establish the intended orientation.
The cover is generally installed with the louvres running horizontally and deflecting downward.
This arrangement helps:
Use the orientation required by the product design and project specification.
Place the Pyrocover over the installed grille.
Centre it so that:
Use a spirit level or square to check its position.
For a door installation, check that the cover remains clear of:
Open and close the door carefully while holding the cover in place.
Use the cover’s preformed fixing holes as templates.
Mark each fixing position accurately.
The fixings should enter suitable door, wall or duct material and must not:
Remove the cover and drill the marked pilot holes.
Select the bit diameter according to:
Remove all drilling dust and debris.
Return the cover plate to its marked location.
Check again that:
Insert the first screw loosely.
Do not tighten it fully.
Install a second fixing diagonally opposite to maintain the cover’s alignment.
Continue inserting the remaining screws loosely before final tightening.
Tighten the screws progressively and evenly.
Do not overtighten.
Excessive tightening can:
The completed cover should sit firmly without rocking or distortion.
Where a second cover is required, repeat the process on the opposite face.
Align the second cover with the first so the installation appears consistent from both sides.
Do not use fixings so long that they:
Inspect all louvres after fixing.
Confirm that:
Do not fill any louvre with sealant or decorative material.
For door installations, open and close the door several times.
Confirm that:
Check that:
Inspect the Pyrocover periodically.
Check for:
Clean using:
Avoid:
The Pyrocover 100 is a decorative and protective cover rather than the active fire-protection component.
The fire performance of the installation depends on:
Install the cover only as part of an approved tested or assessed system where fire performance is required.
