Lonza Wood Protection offers proven fire-retardant treatments for structural timbers and board products and a dedicated web site is now available.

Only accredited, approved and correctly applied fire-retardant treatments allow clients to effectively meet building control requirements and still produce stunning building designs using nature's most versatile material.

Our facility operates to both ISO9001 and ISO14001 standards and is accredited by the UK Wood Protection Association's Quality scheme.

DRICON is the only fire-retardant treated timber with BBA approval and NON-COM Exterior is the only fire-retardant treatment accepted by NHBC for exterior cladding timbers.

Proven fire-retardant treated timbers

Treatments will meet either Euroclass B or Euroclass C surface spread of flame requirements of EN 13501-1. We have global experience in the fire protection of timber and have extensive fire certification for a wide range of timber species in conjunction with Exova warringtonfire, the leading fire test body in Europe.

DRICON - fire-retardant treated timber for interior situations

DRICON is the only British Board of Agrément (BBA) approved fire-retardant treatment for timber and has recently celebrated 25 years of continuous BBA approval. A water-based, humidity-resistant (HR) type formulation, DRICON is designed to protect timbers and sheet materials to be used in interior situations.

Treatment involves pressure impregnation of the DRICON formulation into the timber, followed by careful kiln drying to return the timber to a specified moisture content. A wide range of solid timbers and plywoods are suitable for DRICON treatment.

DRICON treatment has the following accreditations:

  • UK Wood Protection Association approved product
  • Approved London Underground product
  • Approved Fire Protection Association product
  • Independently assessed and approved by the American Wood Preservers Association
  • Independently assessed and accredited with the Swedish Sitac Quality Mark
  • Approved by the National Access & Scaffolding Confederation for the protection of scaffold boards
  • Approved by Chiltern International against the TF2000 six-storey timber frame staircase test

NON-COM Exterior - fire-retardant treated timber for exterior and severe damp situations

NON-COM Exterior is a polymer-based, leach-resistant (LR) type formulation designed to protect timbers and sheet materials to be used in exterior and severe damp situations. In these exterior situations, NON-COM Exterior treated timbers can be used without a decorative coating in exterior situations. However, if a decorative coating is required, Lonza recommend the use of industrially applied DRYWOOD Woodstain for exclusive use on NON-COM Exterior treated timbers.

Treatment involves pressure impregnation of the NON-COM Exterior formulation followed by a careful kiln drying and heat curing process to return the timber to a specified moisture content. A wide range of solid timbers and plywoods are suitable for NON-COM Exterior treatment, as well as specific commodities, such as cedar shingles and shakes and Yorkshire boarding.

NON-COM Exterior treatment has the following accreditations:

  • UK Wood Protection Association approved product
  • National House Building Council (NHBC) accepted product for exterior timber cladding
  • Approved Fire Protection Association product
