What is fire retardant treated wood?
Fire retardant treated wood, also known as fire rated wood or fire impregnated wood, is wood material that has undergone a treatment to improve its fire resistance properties. The treatment is aimed at reducing the ability of wood to burn and contribute to the spread of fire, as well as to reduce the development of smoke and the release of dangerous gases in the event of a fire.
To achieve fire-retardant properties, various methods and treatments can be used. The most common methods involve chemical treatment and modification of the surface layer of wood.
- 1. Chemical treatment:
A common method is that the wood is treated with fire retardant chemicals, also called fire retardants. These chemicals are applied to the surface of the wood or injected into the cell structure of the wood to alter its flammability. The fire retardants work by delaying or preventing the wood from igniting and burning, as well as reducing the spread of the fire. - 2. Modification of the surface layer:
Another method involves modifying the surface layer of the wood to improve its fire resistance. This may involve the application of fire-retardant coatings or boards that protect the wood surface and prevent the fire from spreading.
The fire-retardant wood can be used in various building structures and applications where increased fire safety is required. It can be used for interior decoration, wall coverings, floors, ceilings, doors and other wooden products that need to be protected from fire.
It is important to note that fire-retardant treated wood materials have specific classifications and certifications indicating their fire resistance characteristics. These classifications are determined by tests and assessments according to international standards and building regulations. It is important to follow these classifications and use fire retardant treated wood in accordance with the recommended guidelines to ensure adequate fire protection and safety.
