Old growth forests are not suitable for building material. All of these wood panels came from plantations that are re-planted immediately after harvesting, often from places where there was no forest before.
- ajross 14y agoExactly, that's why engineered wood products are so appealing. Where old style construction would require long, single timbers from 80+ year old trees, products like MDF, OSB and this thing can be done with much younger trees, which yield more net wood volume per acre of farmland per year.
- J3L2404 14y agoTrue. But MDO and CDX can both be made from younger trees and although they are more expensive they are much more durable due to being layers of wood as opposed to glued fibers. LVLs are another good example. Edit: For DIY projects never use MDF or OSB. These products are for production building and are very unforgiving for weekend projects. And dustier.
