Specifiers and other building professionals ask us mostly about:

• WPA Commodity Specifications C1 to C10

• WPA Flame Retardant specifications

• Other specifications such as NBS Z12 and BS 8417

• Suitability of wood preservatives for wood to be used in different situations

• Safety of preservation and other wood protection products

Here you will find access to the latest versions of WPA specifications for preservative and flame retardant treatment of wood and wood-based board materials; advice on using NBS and BS specifications; advice on treatment for different end-uses; and advice on safe use and the regulation of wood preservatives and treatment processes. We provide answers to Frequently Asked Questions so please visit those first as you may well find the answer to your question there.
