Sustainability is a fundamental feature of wood buildings. The use of environmentally friendly fire retardants gives an optimal finish for your designs made of wood. Why not require sustainability also of the fire protection of wood materials?
The natural character of wooden structures and surfaces remain visible with a clear or translucent toned finish. NT DECO is available in thousands of tones from clear to dark and is suitable for both interior and exterior applications. NT NEUTRA provides a cost-effective clear finish for interior applications.
When wood is used in public, commercial and residential buildings, products treated with Nordtreat fire retardants fulfil the strictest requirements.
European fire testing of construction products is based on the Euroclass system (2000/147/EY). Wood products treated with Nordtreat fire retardants typically achieve a reaction to fire classification B-s1,d0 according to EN 13501-1:2007+A1:2009. The classification is based on performance in three standardized tests:

DURABILITY OF FIRE PROTECTION
Fire retardants improve the reaction-to-fire properties of wood products. However, the reaction-to-fire performance may be reduced by exposure to humid conditions and weather, and the ability of the treated products to continue to perform even when exposed to these conditions needs to be demonstrated.
Nordtreat fire retardant treated wood products typically achieve DRF classifications INT, INT2 and EXT according to EN16755:2017. The classifications are based on the fire retardant treatments durability in tests such as: EN 13823, ISO 5660-1, NT 053 and EN927-6. Nordtreat fire retardants protect wood also from impacts of weather and sunlight and enhance wood material’s natural resistance against moulds and fungi.
All Nordtreat fire retardants are M1 emission classified. They also meet the strict requirements of BREEAM and LEED as well as German AgBB and French VOC testing. The proven safety of Nordtreat fire retardants make them an optimal choice e.g. for residential buildings, schools, hotels and hospitals.
