Christmas Shutdown 2019
Please note, we shut down for two weeks over Christmas (from Thursday 19th December 2019 to Thursday 2nd January 2020) which may affect your order. Because our products are not "off the shelf", please check that we can fulfil your order before Christmas if required. Thank you, the iWood Team.
Durability is a measurement of how long specific species of timber would last if a 50mm x 50mm cross section was left in the ground unprotected.
An untreated Oak beam
, which is classed as 'durable', for example, will last 15-25 years depending on environmental conditions.
The following scale of durability was outlined by TRADA, the Timber Research And Development Association.
||Average timber service life
||less than 5 years
||more than 25 years
