FIRE RETARDANT WOOD

Thermory thermally modified pine and spruce are now available with fire retardant properties in collaboration with Woodsafe Timber Protection. Improve your Thermory cladding with durable fire protection.

Fire retardant wood cladding

Building with wood is nothing new, it has been done for generations all over the world. But building new communities where tall, wide and complex wooden buildings are emerging at an ever faster pace is new and requires expertise and technical solutions against fire.

Woodsafe

Technology

Woodsafe offers innovative and durable fireproofing services of wood. Their unique technology refines the wood’s natural properties when exposed to fire and maintains the highest requirements for combustible material.

Together with Woodsafe we can provide fire retardant wood for exterior applications with our thermo-spruce and thermo-pine.

 

Technology & Low energy production

Woodsafes factory is powered by CO2-neutral resources such as wood pellets, a solar energy plant and extensive energy-saving measures that are reported in Woodsafes sustainability report

 

WOODSAFE Exterior WFX, is a flame retardant agent based on an advanced heat-curing polymeric system. The water soluble organic polymer system is applied to timber by vacuum pressure followed by a high temperature curing process. The high temperature chemically converts the water-soluble chemicals to a permanently bonded high molecular weight water insoluble resin.

In the impregnation process, the wood is wetted in its entirety and, the fire retardant is pressed deep into the cell structure of the wood, where it is fixed.

Benefits of Woodsafe Exterior WFX™

COMPREHENSIVE

Fire protection fixed at depth and on all 6 sides by using monitored vacuum pressure process

CERTIFIED

Type approved certified EN16755 EXT and Classified ASTM D2898 prove the suitability of installing fire-impregnated wood in an exterior environment without a protective paint layer

FIRE CLASS B

Wood treated with Woodsafe Exterior WFX achieves the highest Euroclass for combustible materials – Bs2,d0 (s2) 

NON-TOXIC

Exterior WFX impregnation is not classified as hazardous to health or the environment

NO LEACHING

Exterior WFX is based on an advanced heat-curing polymer technology that forms a waterproof permanently bonded fire impregnation.

LONG LIFESPAN

Exterior WFX lifespan is estimated to be 30 years or longer depending on geographical location, latitude, wood type and application

NATURAL WOOD

Unchanged texture and shade and WFX allows natural ageing of the wood

NATURAL MOISTURE CONTENT

Does not increase moisture absorption
