Fire Retardant Treated Timber

When fire protection is required for construction timbers it is vital that you have a proven treatment you can trust. Silva Timber Products offers tried, tested and proven DRICON and NON-COM Exterior fire retardant treatments that give you creative freedom in terms of design and application and provide a complete assurance of a built-in and highly effective fire protection performance that will last the lifetime of the timber component.

The highly controlled treatments impregnate all faces of the timber or board products, creating a permanent long term protection that requires no maintenance - a real benefit over short lived products and site applied and uncontrolled fire retardant coating products.

Both treatments meet the requirements of European Standard EN 13501-1, to either a Euroclass B (generally timbers to be used in escape routes or staircases) or Euroclass C rating (generally timbers to be used in walls or ceiling linings).
