Is this timber 'treated' ?

[Post and beam]

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

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

Thanks Stu. I will. 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.

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

Just checking up on a TF company. It is already in place with the walls mounted.

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.

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!
