How It's Made: Cross Laminated Timber (CLT)

- In this episode of WoodSolutions InFocus Laurence visits a factory which produces cross laminated timber, or CLT. CLT is an engineered timber product that is quickly growing in popularity in the construction industry. With two-way action and high tolerance of shear forces, CLT panels can generally be used instead of concrete, saving huge amounts of greenhouse gas emissions. Here, Laurence sees how CLT is produced and learns more about the quality checks involved in the manufacturing process.

Thanks for watching our video! Did you get something out of it? Is there another topic about wood, wood products, or designing and building with wood that you would like us to explore? Let us know in the comments and we'll see what we can do.
Thank you for sharing Wood Solutions team. I'm so pleased to be involved with the adhesive and surface bonding agents in the engineered timber industry. I see this technology and product as a great step forward in building technology if we are serious with sustainability, resources and efficiencies in construction and energy efficiency. Thank you again with an excellent video presentation!
Greg, perhaps you can answer my question if you are still involved with Wood Solutions. In the video it was said that treated woods could be used. It is my understanding that treated wood has been found to be carcinogenic. My concern is that using that plus all the adhesives and sealants necessary to make this product will lead to a living environment with VOCs and/or possible long term health issues. Nothing was mentioned in the video to allay my concerns. What can you tell me about these things? Cheers!@@gregtreble9086
Not a lot of info on how the smaller pieces of wood are prepped and glued together. I imagine that’s the most important part.
The use of adhesives and plastic sheeting ensure there’s still lots of oil involved in the manufacture of CLT 🙃
LOVE THE MUSIC
I saw many buildings all over the world, in a structural analysis program's website, being made in CLT and I was actually curious how it is any different from the ones used in the past.
great.I hope it will be everywhere in the world
Interesting. Thanks !!
SUPER!!!!!!!!!!!!!!
Thank you for the excellent explanation! Why is softwood more commonly used in CLT panels than hardwood?
Softwoods grow faster than hardwoods and therefore cost less and are easier to regrow in forests.
CUSP in Tasmania are making a hardwood CLT
very nice video!. great
Friends, good afternoon! Have you ever thought to make a CLT in 2 layers, 20mm thick and 2.5×1.25 meters in size.? (Glue lamellas with a thickness of 10mm.) So that 1 person could lift them. (As OSB).
CLT that thin would not pass structural requirements to support the roof even if nailed or screwed together
Thanks for this video. Can you give any indication on cost for factory applied AV barrier vs a membrane field applied? A percentage? I’m sure the labor costs alone a a good reason to factory apply.
Great video, thanks. It’s the AVB applied at the factory comparable in cost to field applied?
I'm curious about what kind of glue is used at this factory.
the glue is usually non formaldehyde vapor permeable glue .
@@siriosstar4789 what's the lifespan of this type of glue?
radu- not sure . i think it's the same glue that is used on laminated beams which seem to last the life of the house but i'm not certain about that .
Awesome. But it's kind of ironic that CLT is made in a completely pre-engineered steel building!
It’s harder to get long spans on a completely mass timber build.
So do CLT houses still need interior insulation or not? And is Drywall sheet rock required for interior for CLT HOUSES? I'm asking because i may consider building a house in Tasmania with CLT!
Chris ,insulation requirements are based on the thickness of the panels and the climate .
Wood fiber insulation panels can be attached directly over the exterior via screws . furring strips are then added vertically , also screwed in the CLT and wood paneling or plates to accept stucco can be applied . This makes for a very warm or cool house requiring very little heating or cooling .
Why that factory was made of steel instead of wood ? :)
Because of the large spans and structural strength requirements that need to support the crane (and its load) that run the length of the factory.

Very cool video! Thanks for posting!
😍
interesting video.
I am very affraid that global warming is waking up sleepy vulcanos, increasing earthquakes tragedies as extreme weather phenomena, we can not sit and wait to lose everything, friends, you need to consider that we have to neutralize the pollution maybe not using fossil fuels for cars or trains, but airplanes for sure, we need to get reasonable, you are doing a great job Indeed
global warming isn't going to do anythign about volcanos. It will however warm the seas which disrupt the flow of currents in the ocean and increase the veracity of hurricanes.
Oh yezzzzzz, go for it champs, l am the biggest supporter of yours, web technologies created a lot of new wealthy tycoons, they all deserve to get inspired for further smart investments of new touristic atractions of new cyber happenings dating virtual friends and move on, building up a better humankind. Too much people is wasting too much time for damaging the others business instead of being focused on building up its own private haven, until we bring to life any desert on this planet and save us from getting fried for good. We need to neutralize pollution right away, oh yezzzzzz, anyone willing to get involved plizzzzzz do before its too late
What a great explanation about how CLT is made!
Do you use any type of glue release to protect your equipment from the glue?
It’s insulting to our intelligence to show us real factory footage while the harvesting of the wood is shown as a cartoon with a bird happily flying along. What are you hiding?
Hello, can bamboo alone can be made as a feed stock or a maximum content in the feed stocks?. What's the criteria for the basic feedstock combination in terms of strength and other parameters?
It's so good they make it in a steel structure 😂
SHHHH
Nice Video, aboviously the bottle neck for the production capacity will be the pressing in this plant. The cold pressing consumes 25-30 minutes, and only can press several boards each time, they may need more press machines.
could work during the night shifts
Thank you
Engineering wood products are renewable resources
what is the use of it? we are cutting the trees and using it to make our own houses right!!!!!! low carbon emission is the main reason behind it. but is this really environmental friendly? by cutting trees we are harming environment. what is the use of it then?? in place of lowering the carbon emission during construction we are responsible for destroying our global ecosystem. it should be banned
Cutting trees isn't inherently bad. Trees regrow, and while it does alter forests, it's possible to do it in the most responsible way possible. It does not have a high carbon impact relative to steel, concrete, etc, as all the carbon in wood comes from the atmosphere (CO2).
Proper forest management is certainly the right concern. Mass timber is used as structural beams in large buildings, replacing steel and concrete elements.

Beteeeee
mauj kardi
Excellent production line.
the lisp my guy
Nice... clt solution for eco sky scraper?
Ok
Thank you for this informative video. I learnt a thing or two about CLT now :)
