FORZA DOORS TIMBER DENSITY CHART The characteristics and uses of a broad range of species seen in the UK are contained in this Wood Information sheet. The characteristics shown in the following tables are described below. Species The standard names recommended in BS 7359 Nomenclature of commercial timbers including sources of supply are given in bold in the tables. The botanical names are included to avoid confusion between different timbers which may have similar common names. The main regions of origin are indicated for each timber. Colour(s) Related to the heart of the species. Most timbers vary in colour and will change with use, the application of finishes and exposure to light. Unprotected timber exposed to the weather will discolour and may develop and may develop mould growth. Density Varies depending on species and moisture content. Averages at 15% moisture content are quoted; 0.5% of the given weight can be added for every 1% increase in moisture content. (*Indicates that density can vary by 20% or more.) Texture Surface texture is classified as fine, medium or coarse. Availability Described in broad terms as regular, limited or variable. It will vary both from time to time and throughout the country. Some species may not be available as raw material (or only in time quantities) but may be seen as veneer on furniture or panelling. Other species have been included because of their historical or technical interest or importance. Trading in some species is governed by CITES - the Convention in International Trade in Endangered Species which lists species in three categories: Appendix I - Trading prohibited Appendix II - Trading permitted subject to export permits from the country of origin (and re-export permits as appropriate) and UK import permits from Department for Environment, Food and Rural Affairs. Appendix III - Species protected within individual party states. Note that CITES listing covers the raw material only, not manufactured products. CITES is implemented within the European Union by EC Regulations; the species listing is broadly equivalent to CITES listing. In the UK this legislation is backed by the Control of Trade in 1997. Further information is available from www.ukcites.gov.uk. Price Price is difficult to quantify since timber is affected by currency variations. However, to give a general indication of comparative prices, the following terms are used: High Over £1,000 per cubic metre Medium £550 - £999 per cubic meter Low Up to £550 per cubic metre (1999 prices) The prices relate to decorative hardwoods: structural softwoods will normally fall into the cheaper half of the low category. Prices are for kiln dried stock where appropriate.
