Cypress (Callitris glaucophylla) is unique amongst the pines of the world due to its durability being equal to the most durable hardwoods and the strength of light to medium density hardwoods while being a softwood species. Cypress has a widespread natural occurance in drier regions of Australia. It is a medium to large tree reaching 25 Metres in height and is a self generating species.
- Cypress is the only softwood in the world that is Termite Resistant.
- Shrinkage to 12% MC. 2.6% (tangential); 2.4% (radial) and unit shrinkage 0.26% (tangential); 0.22% (radial).
- Density : 675 kgm3 at 12% moisture content: approximately 1.5m3 of seasoned sawn timber per tonne.
- Durability above ground : Class 1 - life expectancy over 40 years. Heartwood highly resistant to decay when fully exposed to the weather.
- Durability in-ground. Class 2 - life expectancy 15 to 25 years. Heartwood moderately resistant to decay when used in the ground.
- Cypress has a high natural durability and because of its strong aromatic odour it is favoured as a building material for saunas.
- Cypress is used in construction for sawn timber (usually unseasoned) in general house framing, fascias, barge boards, fencing, cladding, flooring, linings and joinery. Also used for decorative products such as internal quality furniture, outdoor furniture, turning, joinery, carving and parquetry flooring. Can also be used for beehives, oyster stakes and jetty piles (low salinity river or canal situations)
- The sapwood is creamy white, distinct from heartwood, and the heartwood is light to dark yellow brown. The texture is very uniform with some figure and numerous knots.
- Cypress is available in abundant quantities for export in sawn and processed timber products.
