Marine Plywood [BS1088] information

Marine plywoods are manufactured to BS1088 using timber veneers that are classified as durable, of a high quality and bonded with an exterior glue.

The glue used on marine plywood is the same as used on an exterior plywood. It is the durability, thickness of the timber veneers and the makeup of the plywood [no voids] that are required to conform to BS1088.

Flame Retardant Technical information

There have been some changes in the

specification of wood based panel products. 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been superseded by European specification Euro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.

The company are members of the Timber Trade Federation and signatoriesof its Responsible Purchasing Policy.

dhh commitment

Commitments for the Responsible Purchasing of Timber and Timber Products1 Management StructureThe 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 well-managed 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 LegalityThe 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 SpeciesThe 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 MonitoringThe 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 CertificationThe 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 well-managed 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 ImprovementThe 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.
