MATERIAL AESTHETICS
Visible timber and natural materials should retain their design identity.
PURE FIRE PROTECT
Fire protection without unnecessarily hiding the material.
Clear, water-based fire protection technology for defined timber, natural-material and selected specialist applications — developed as a controlled system comprising substrate, application, coating quantity, optional top protection and technical evidence.
THE CHALLENGE
Combustible materials need protection without losing their identity.
Visible timber and natural materials should remain visible. Smoke development and burning droplets or particles matter alongside flame spread. The relevant fire class belongs to the tested build-up, not automatically to every application of the material.
SMOKE & BURNING DROPLETS
Fire performance is not assessed by flame spread alone.
SYSTEM, NOT SINGLE PRODUCT
Substrate, application quantity, top layer and use affect assessable performance.
A fire classification is not a material label. It applies to a specifically tested system configuration.
MATERIAL BASIS
Clear protection function on a water-based system basis.
PRODUCT FORMClear water-based solution / dispersion
DENSITYapprox. 1.4 g/cm³ at 20 °C
SOLIDSapprox. 50 wt.%
VOC / SVOC<0.01 wt.% according to available TDS basis
TIMBER APPLICATIONtypically 200–250 g/m² · typically 2 coats
Existing documented product basis — SOURCE VERIFICATION REQUIRED where original TDS/SDS assignment is not available in the repository.
FIRE RESPONSE MECHANISM
Heat activates a functional protective barrier.
TRANSPARENT PROTECTIVE LAYER
The treated surface should remain largely visible in normal conditions.
HEAT INPUT
Heat and flame exposure activate the mechanism.
MINERAL FOAM / BARRIER STRUCTURE
Available technical documentation describes formation of an insulating mineral foam layer.
SYSTEM EVIDENCE
Resulting fire performance must always be assessed for the real system build-up.
SYSTEM ARCHITECTURE
Fire protection is created in the defined build-up.
SUBSTRATE
Defined timber / wood-based substrate or another project-specific substrate requiring assessment.
PRETREATMENT
Substrate condition, moisture, compatibility and any defined primer.
PURE FIRE PROTECT
On timber, available basis indicates typically 2 × 100–125 g/m².
OPTIONAL TOP PROTECTION
Only where defined for the specific system, for example a clear-coat component.
DOCUMENTATION
Quantity, climate, drying, batch, photographs and acceptance.
A fire classification is not a material label. It applies to a specifically tested system configuration.
APPLICATION ROUTES
One technology. Different validation routes.
TIMBER CONSTRUCTION
CLT, timber façades and interior fit-out.
THATCH & NATURAL MATERIALS
Thatch, straw and historic / natural building materials.
PUBLIC BUILDINGS
Schools, hotels, childcare and assembly spaces — only with the relevant system evidence.
COMPOSITE PANELS / INDUSTRY
Panels, edges, corners and process areas.
BATTERY / HIGH TEMPERATURE
Development route only.
WILDLAND / ACTIVE FIREFIGHTING
Separate development route only.
Direct flame exposure of different test assemblies
The webcut shows three internal test sequences using cardboard, wood and straw. Direct flame exposure remains visible in all three sequences, and the final sequence ends while exposure is still in progress.

TESTING & EVIDENCE
Strong test data. Clearly defined scope.
The following values are presented as the available documented test basis. Original reports and exact product/system assignment require verification before a higher evidence claim is made.
SBI PERFORMANCE
FIGRA101 / 58 / 79 W/s · mean approx. 79 W/s
THR600s7.0 / 5.4 / 5.6 MJ · mean approx. 6.0 MJ
SMOGRA0 / 0 / 0
TSP600s27 / 30 / 25 m² · mean approx. 27 m²
DROPLETSNot observed in the documented dataset
TARGETB-s1,d0 for the documented tested system configuration
These values apply exclusively to the documented test build-up. They do not replace formal classification or retesting for different substrates, layer thicknesses, top layers, edges, corners, combinations or applications.
Fire performance means more than flame spread.
s1
Favourable smoke classification in the documented configuration.
d0
No burning droplets / particles in the associated dataset.
SMOGRA 0
In the available SBI dataset.
APPLICATION & QUALITY ASSURANCE
Repeatable fire protection requires repeatable application.
SUBSTRATE
Moisture, compatibility and any primer.
CLIMATE
Use documented processing conditions where available.
APPLICATION
Spraying, rolling or brushing; on timber typically 2 × 100–125 g/m².
DRYING
Use only existing TDS values where verified.
DOCUMENTATION
Batch, material quantity, climate, photographs and acceptance.
SOURCE VERIFICATION REQUIRED: original TDS/SDS and processing documents are not fully available in the repository.
REGULATORY PATHS
Same technology. Different evidence routes.
TIMBER / INTERIOR
Fire class, smoke, VOC and use.
FAÇADE / HIGH-RISE
Additional façade, large-fire and national requirements.
THATCH / ROOF
External fire, weathering and ageing.
COMPOSITE PANELS
Surface, edge and corner.
BATTERY / INDUSTRY
OEM-specific development and test route.
WILDLAND / FIREFIGHTING
Independent extinguishing-agent, equipment, toxicity and corrosion route.
A good fire classification on a defined timber system is not a clearance for façades, high-rises, battery applications or firefighting use.

Which build-up needs fire-performance evaluation?
We consider substrate, use, layer build-up and evidence objective together to define the appropriate test and system route.
