Question

Can you advise a timber product that has a 100 year design life certification that can be used for internal timber studwork?

Woodsolutions Answer +

For timber, warranties are generally given in relation to a specific hazard. For example, preservative treated timber may be supplied with a warranty, or guarantee, that it will achieve a specific service life. In the absence of hazards such as termite attack, storm damage, water leaks and similar events, internal timber studwork has an unlimited service life. Indeed, there are historic timber buildings more than 100 years old that have escaped such damage. However, we don't know of any producers offering 100-year certification.

Question

Have an order for 200x175mm in sugar gum asking for F17. I can either cut it boxed-heart or cut through heart (but not excluding it) - like a sleeper cut. Always called this F-14. Am I correct? Would I be correct in thinking this size heart-free would be difficult in any sawlog to 600mm diameter? 

Woodsolutions Answer +

To make F17 grade, unseasoned sugar gum has to comply with Structural Grade no. 1 in AS 2082. In pieces where the smaller dimension is 175mm or more, this grade requires heart to be within the central one third of the width and thickness of the piece, so it would have to be boxed heart.
