Preserved moss meeting fire safety standards

In professional plant-based decoration projects, aesthetics alone are no longer enough.

Hotels, restaurants, offices, retail spaces, exhibition stands and event venues are subject to strict fire safety regulations, particularly in public-access buildings.

Within this framework, Phocealys offers fire-retardant preserved mosses, designed to combine a natural plant appearance, durability and fire compliance — without limiting creative freedom.

Why treat preserved moss with fire retardant?

In public-access spaces — hotels, restaurants, shops, trade fairs or events — safety is not optional. Regulations require decorative materials to meet strict fire reaction standards.

Preserved moss is a natural plant material. Fire-retardant treatment makes it possible to:

• delay ignition,

• limit flame spread,

• reduce post-combustion,

• prevent the formation of flaming droplets.

In other words, the material does not become non-combustible, but it exhibits controlled behaviour in the event of a fire, compatible with professional regulatory requirements.

Our preserved mosses are certified M1, ensuring low flammability and limited flame spread. This makes them ideal for green walls, frames or exhibition stand coverings while remaining compliant.

A fire-retardant treatment adapted to preserved plants

Phocealys fire-retardant mosses benefit from a flame-retardant surface treatment specifically formulated for preserved plant materials.

This treatment:

• is applied by spraying,

• is based on a water solution,

• is odourless, non-toxic and colourless,

• does not alter the texture, flexibility or natural colour of the moss.

The result: a moss that looks identical to standard preserved moss, but with a fire safety level suitable for professional use.

Fire-retardant preserved mosses available from Phocealys

Fire-retardant ball moss

Widely used in green walls and volumetric compositions, fire-retardant ball moss retains:

• its natural flexibility,

• its excellent relief effect.

It is particularly suitable for decorative wall surfaces and creations requiring volume.

Fire-retardant Provence moss

More graphic and irregular, fire-retardant Provence moss offers:

• a more textured appearance,

• a rawer vegetal reading,

• excellent coverage capacity.

It is often chosen for contemporary projects, wall coverings or designs with a strong visual identity.

Fire-retardant production on request: fern moss and lycopodium

To meet specific project requirements, Phocealys can also offer other fire-retardant moss varieties on request:

• fern moss,

• lycopodium moss.

These productions are carried out after technical validation of the project (substrate, surface, installation conditions, final use).

Fire classification: what M1 really means

The fire-retardant mosses offered by Phocealys have undergone laboratory testing according to NF P 92-507 standards and achieved an M1 classification under defined installation conditions.

M1 classification indicates:

• very low flammability,

• no flaming droplets,

• stable behaviour when exposed to heat.

This level is required for decorative materials used in public-access buildings.

French classification and Euroclass: understanding equivalences

The French classification (M0 to M4) and the European classification (Euroclasses A1 to F – EN 13501-1) are based on different testing protocols.

There is therefore no automatic correspondence, but a generally accepted indicative technical equivalence:

A solution designed for professional projects

With its fire-retardant preserved mosses, Phocealys provides a concrete response to professionals facing increasing regulatory constraints.

Fire safety, durability, natural appearance and creative freedom are no longer incompatible — provided that technically controlled and well-documented materials are used.

Safety and peace of mind at the heart of your creations

Phocealys fire-retardant mosses allow you to fully express your creativity without compromise. Their specific treatment ensures enhanced fire safety without altering flexibility, texture or colour.

The result: elegant, authentic plant decoration perfectly suited to public spaces and major events.

Durability and cost-effectiveness

Like all our preserved solutions, this moss retains its original appearance for years, without watering or maintenance.

It is also a durable and cost-effective investment for decorators, landscapers, interior architects, set designers and demanding florists.

An innovation born from a French partnership

This product is the result of close collaboration between Phocealys and its French production partner. Together, we aimed to offer the market a reliable and innovative solution that meets professional standards.
