Post and beam Posted October 13 Share Posted October 13 Does anyone that knows have a view on whether this timber is 'treated' timber. And by definition therefore suitable for a soleplate Many thanks in advance keith Link to comment Share on other sites More sharing options...
stu w Posted October 13 Share Posted October 13 (edited) Difficult to tell from that picture, could just be discoloured from age or the sun, but could also be vac vac treated. I would say it's not pressure treated personally . Trim a tiny bit off the end and see if there is impregnation marks Edited October 13 by stu w Link to comment Share on other sites More sharing options...

I hoped the numbers designated it in some way as 'treated'. Personally i dont think it looks like anything other that white pine internal timber. The cut ends do not look like they have and impregnation of anything. Link to comment Share on other sites More sharing options...
saveasteading Posted October 13 Share Posted October 13 (edited) I think that is treated. We had lots like that and I thought it was just sprayed but the website says it is thorough. May look it up later. Did it now. Ours was Protim treated. Looks yellow on the surface like yours. Apparently it is a pressure treatment that penetrates (tho it isn't visible to me in cuts.)

If in doubt especially for a sole plate, I would use pressure treated timber Link to comment Share on other sites More sharing options...

Post and beam Posted October 15 Author Share Posted October 15 I am familiar with DOP certification in my working life. The displayed information showing compliance should be legible and enduring. I dont find the markings in the picture clear enough to read so i think i need to ask to see the paperwork that applies. Link to comment Share on other sites More sharing options...
saveasteading Posted October 15 Share Posted October 15 There is an explanatory video on the James Jones website. Interesting. Google James Jones timber treatment. I didn't know there were so many classes of treatment according to use. Cuts need painting! 1 Link to comment Share on other sites More sharing options...
