The new European classification has caused some confusion. Prior to this BS475 part 6 & 7 were used and these fell into two groups: Panel sheet materials that are pressure impregnated with chemicals by specialist treatment plants. Panel sheet materials that are manufactured with the chemicals introduced during manufacture. Class 1 & Class 0 are still specified although they have been superseded by European specification Euro Class C and Euro class B. Euro class Can be used where Class 1 is specified as it meets the requirements of BS476 class 1. However Euro class B CAN NOT be used as an alternative to the old BS476 Class O specification. Neither specification can be substituted for one or the other. Before an alternative specification can be used, contact must be made with the local fire officer or authority to get confirmation of any amendments. Medite FR is the only MDF that meets both BS 476 Class 0 and Euro Class B and therefore can be used in both situations. Other MDF manufacturers are currently unable to offer this dual specification. douglas fir plywood douglas fir plywood osb/softwood plywood osb/softwood plywood EXT DOUGLAS FIR SOFTWOOD PLYWOOD (ROTARY CUT) 2440 x 1220 O.S.B. 11mm One Clear Face [70] 11mm Two Clear Faces [70] 19mm One Clear Face [40] 19mm Two Clear Faces [40] OSB OSB 2 OSB 3 8mm [112] [112] 9mm [100] 11mm [82] 15mm [ 60] 18mm [ 50] SITE PROTECT 18mm [ 50] SOLID CORE EXT DOUGLAS FIR SOFTWOOD PLYWOOD (ROTARY CUT) 2440 x 1220 12.5mm One Clear Face [66] 19mm One Clear Face [44] 19mm Two Clear Faces [44] Solid B Core veneers used throughout inner plies.

Commitments for the Responsible Purchasing of Timber and Timber Products 1 Management Structure The company has appointed a Director to be responsible for the implementation of this Policy and will ensure that relevant environmental issues are discussed regularly at the highest level of management. The company will ensure that all employees associated with timber purchasing are aware of the Policy and its commitments, and are given appropriate education and training to allow its full implementation. 2 Responsibility The company recognises that it has a responsibility to the environment, customers, suppliers and staff to base its commercial activities on wellmanaged forests. 3 TTF Code of Conduct The company is committed to the Timber Trade Federation Code of Conduct and applies the Environmental Code of Practice to all wood procurement activities. 4 Legality The company is committed to purchasing all timber from legal sources and will seek evidence of compliance from suppliers that they are operating in accordance with the laws of their country. The company unreservedly condemns illegal logging practices and will keep informed of international processes and changes in legislation. 5 Endangered Species The company will not trade in timber species prohibited under Appendix 1 of the CITES legislation and will obtain the appropriate documents for trade in all other CITES listed timber species. 6 Traceability and Supplier Monitoring The company will perform a Risk Assessment on all Suppliers, as documented by the RPP. The assessment will seek to provide the clearest practicable information regarding the sources of raw material used in the manufacture of wood products. This information will form part of purchasing decisions and will be made available on request to independent verifiers. 7 Timber Certification The company supports international efforts to improve forest management, for example, the development of credible timber certifi cation schemes. This company recognises that the independent certifi cation of forests and the process chain is he most useful tool for providing assurances that the timber comes from legal and wellmanaged forests. The company will only accept, or use labels or certificates that include environmental or sustainability claims only if they are supported by publicly available standards drawn up in a fully participatory, transparent and objective manner, and are backed by independent inspection. 8 Avoid Boycotts The company will not encourage boycotts or bans on specific species of timber. Notwithstanding this, the company will cease to purchase any timber and timber products whose supply is in breach of the Timber Trade Federation Code of Conduct and, inparticular, the Environmental Code of Practice. 9 Continuous Improvement The company is committed to work with relevant trade organisations, NGOs and governments to develop its purchasing policy. The company is committed to continuously raise the proportion of timber and timber products, in accordance with the stepwise approach, that originate from legal and sustainably managed forests. 10 Reporting and Audit The company will report annually to the appointed auditors. The auditors will assess and verify the company s progress and compliance under the Policy. A copy of the company s Responsible Purchasing Policy Company Commitments will be available to all stakeholders on request.
