I worked In a clt factory in Canada, it is by far a superior product, not cheap, but you remove the cost of a lot of other parts of construction.
Sustainable forestry is the key and needs to be scrutinized. Forestry is big business and profits usually come before environmental impacts.

My adventure with the woodworking began with projects from Woodprix.

The last building is in Prince George British Columbia. It's the Wood Innovation and Design Centre and it's an absolutely amazing building.

Yo! I looked this up because I work on these all day!

[LJLancaster]

Love CLT. I believe we are going to see some really interesting things and the material is explored further.

Produced in Austria by Enso on two locations Ybbs / Bad St. Leonhard. I didn’t know about that! Makes me (Austrian) proud.

We design and build a CLT small house in China back in 2017, but it wasn't received well in the industry due to the cost. but I think CLT has a bright future once manufacturing capacity can be solved.

I'm in Thailand and the termites here would love it. Plywood, any wood except teak here and they gorge on it. Roof supports have to be steel.

The man behind the voice! Love this channel and it’s narration.

Can't wait until this is more readily available. I love everything wood. It is the true Carbon storage device. Plant more trees and harvest carbon.

Great explanation! We're looking forward to start using CLT here in Brazil! Great channel! Keep going guys!

[sciencevids]

I live for interesting and informative videos such as these. Especially if they are mentioning structural and manufacturing engineering related information. 😊 So thank you for this. Please keep posting more thank you so much.

Meanwhile in 2021: timber prices have shot up 200% and construction luber is easily up 400% 😬

[kkeeper]

the fire issue baffles me because even steel structures are now covered in sprayed on fireproofing called SFRM so why could this not be used with CLT as well?

[axgoat]

I'm sold but this could put pressure on the forest industry and there's the backstory.

[nougatbitz]

Aside from moisture penetrating the wood, what about woodworms or termites, or even just mice? Wouldn’t they thrive in the softer material?

[sndrb]

I am having a hard time finding fire resistance tests, esp. with regard to gasses expelled and possible delamination. I found one test where delaminating set off a cascade effect setting the entire structure ablaze.

With lumber at $1050 this must be the most expensive building material.

At this rate old growth forests will soon mean 40 years of growth before harvest. The truly old and majestic forests never to be seen again in our lifetimes.
I live in bc and have watched my local hills be wiped out in the past five years. Most folks don’t know that it’s happening. Wish they could make an industry of 200 year turnarounds, that way we could at least still experience the spiritual uplift and unparalleled beauty of ancient stands, not to mention the ecological diversity that only comes with deep time. Breaks my heart :(

Building from wood is a perfect way to recude carbon emissions. The carbon is stored in the wood and new forest will grow back to store even more carbon. A pro tip: We have lots of timber to sell in Finland ;)
