How Is Pressure-Treated Lumber Made?

Treated lumber can be a great resource for the job at hand, but there are misconceptions about it that can prevent people from enjoying its benefits. In this series, Dennis McWhirter of Exterior Wood addresses these misconceptions head-on as he answers some of the most common questions based on his nearly three decades of experience in the industry. Our hope with this series is that you’ll make your next lumber-purchasing decision an even more informed one. In part one of this series, Dennis answers this question: How is pressure-treated wood made?

Great video. Some people think that they do pressure treating themselves. This is a good explanation why it doesn't work.

[haifamarkets]

What are the chemicals used? are they save? what does it help agaisnt?

[animequeen]

I've wondered how pressure treating lumber works.

[xmp]

Is it safe to assume that pressure treated wood is more expensive in the winter months than in summer months because of how long it takes to cure?

[ShmooyShmoo]

I wonder what would happen if a person was pressure treated”?....sounds like the beginnings of a super hero movie.

Love when people are really excited, proud, and interested in their work.
May be a bad comparison but have you been to a fast food restaraunt recently?

[christopherzotynia]

he keeps saying chemical like hes avoiding the name, why not tell us what it is?

[divyeshbhavani]

can anyone answer my question, so when does the kiln drying process comes in I mean is this process done after kiln drying or before?

[chrisbolen]

is this the same process for both ground-contact rated wood and above-ground wood?

[GaryGoat]

Referring to it as “the chemical” sounds very sketchy

[cuongdo]

the video image is too poor, you need to fix it more

[paulbriggs]

It would be nice if at some point after the pressure treatment they would dry it completely for us so we can use it right away and not try to find somewhere to store it ourselves,

[ArtisanTony]

So a new process of removing the excess chemicals in a quicker fashion needs to be created. Come on man :)

[Barricade]

Since everyone seems to want to know what’s being put in the wood it’s
chromated-copper arsenate. Your welcome

[officedotie]

Not sure thats a good process those bales of wood were tightly packed hw is the chemical to penetrate when there is no gap all arounf them ?

[TrevorBodogh]

Failed to answer / teach the fundamental question: what is the purpose of PT wood. Amazing.

[alexeierchov]

So the correct name would be "chemical treated", where the "pressure" in the process?
