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.

It is extremely lightweight compared to concrete too, way less weight for the building to sustain. But, it does take a bit more space because the columns and beams are wider.

True, but you should know that that is only over small time scales. Over longer time scales, any level of tree planting will become carbon neutral. The carbon fixed by the plants from CO2 is later released by the death, a decomposition, of these same plants. That being said, on shorter time scales, this may be worthwhile.

And the vast majority of steel and concrete isn’t carbon neutral at all both are actually significant sources of carbon emissions currently

Hi Nougabitz, I work for Stora Enso (our factory in the video) and in particular the CLT division. The CLT can be treated for termite protection, for instance this is done for the Australian or New Zealand markets where termites are more of an issue. We don't do this for the all countries as termites are a localised problem, for example in the UK they are not an issue, but for those countries effected they can be treated for. Mice are never really a problem, but certain local insects are designed for.

This is not a new thing, the arches carrying the roofs of the central railway stations in Malmö and Stockholm were made in the 1920s and there's an aircraft hangar built in 1937 with a span of 55 m. Those were weather protected structures so I think it's another kind of glue since 50+ years.

@gaz6351684 6 жыл бұрын
Hi Ciaran, I work for Stora Enso (our factory in the video) and in particular the CLT division. Certainly not a silly question! What you refer to is called de-lamination. Our ETA is based on testing that simulates this effect over 50-100 years. The glue we use is a polyurethane formaldehyde free glue, and is actually less than 1% of the mass of the panel. One of the most important factors to avoid de-lamination is ensuring that humidity doesn't vary greatly throughout the year, as this is a main cause of expansion and contraction of the timber and therefore de-lamination, but in the very rare situations and harsher humidity variances where this may occur, its usually just to the outer lamella (layer) and holds no significant structural issues in regards to load bearing capacity, which is usually taken by the internal lamellas. CLT and Glulam beams for instance, have been used for swimming pool environment's etc, where the humidity level becomes more of a factor. The timbers will never really peel away from each other, instead its a case of minor cracking to outer timber, but again, this is rare and can be easily avoided. As Urban F points out, its really as case of correct protection of the timber from moisture, and designing for certain humidity levels that will ensure this doesn't happen.

I helped build a c.l.t. plant in Columbia falls montana, we made rig mats for the oil boom. the glue we used is made by Henkel (Loctite) and is basicly gorilla glue on steroids. direct sunlight is one thing pur bond hates. it is a form of plastic though so there isn't much that can cause de lamintation. maybe chemicals or solvents that are unlikely to be soaking into a structure. the destructive tests that certified lumber has to go through are more than you would expect. I spilled some of this glue in my driveway, it's still there. I am waiting for the sun to break it down enough that I can remove it.it has been four years now.....

Due to the relatively light material i could see this getting ripped apart or soaked and then carried in the streams.

Hi, I work for Stora Enso (our factory in the video) and in particular the CLT division. This is certainly an interesting idea, and the very old Japanese method (Shou Sugi Ban) of creating durability and fire protection is suitable for some projects. However, for nearly all of the buildings we supply, to ensure guarantee's, warranties, mortgages, insurances etc, the panels have to be designed for fire very accurately, to ensure they perform against fire as expected and required and ensure the safety of the building and the people inside. One issue with Shou Sugi Ban for modern construction would be that there is no accurate way of charring or measuring how that char has effected the panel. So although I'm sure its possible, for the very large scale buildings we supply, we have to use much more accurate and tested methods such a FR plasterboard or surface spread of flame treatments for us to be sure the building will perform as required. You can find a number of fire design guidance and documents for CLT here: www.clt.info/en/media-downloads/approvals-documents/technical-applications/

In my job I've had many years of experience with passive fire protection, timber fire door frames and fire doors, as well as FR plasterboard (and various other boards and coatings). No amount of PR will sell me on this idea. I would not spend a single night in a multi-storey building of this construction. Performance of materials in a fire test is one thing. Real world fires are another matter. Every aspect of the building needs to perform, even after many years of occupation and the activities that go with that. Using laminated timber as the structural elements means the passive fire protection is critical. In practice, it will be vulnerable to compromise.

Hi Falcon, I work for Stora Enso (our factory in the video) and in particular the CLT division. Our ETA gives an assumed working life of 50 years, however in regards to mortgages and warranties on insurances, this covers over 60 years. CLT is very robust, and as long as the building is built correctly and detailed correctly, there is no reason these buildings will cannot last much longer than that. If you take examples from Japan for example, where there are timber structures that are over 1000 years old, the degradation of timber in the right conditions and protected correctly means they should easily stand the test of time.

Hello, I work for Stora Enso Wood products division, the CLT company in the video. The current estimated CLT capacity across all suppliers internationally is approximately 1.25 Million m3 per year. The majority of mass timber at the moment is produced in Europe. In 2019 there was an estimated 159 million hectares or forest land across Europe and within this there is a growing stock (ie timber that is available for wood supply) of about 27.1 Billion m³, so to put that into context, all mass timber produced globally annually is the equivalent of around 4-5% of Europe’s forestry stock, not including of course all forests outside of Europe. When you take into account areas like Russia and Canada, there is a strong forestry stock globally, and mass timber consumption is a very small % of it. This is of course fully regenerated annually, because we grow more than we use. In regards to total European forestry stock, this has increased by 10% since 1990 because more trees are planted than are harvested every year, again showing a strong forest supply and future growth. I would suggest that considering CLT has been around for nearly 30 years now, and in the last 30 years forest stock in Europe has in fact grown by 10%, I would say this is strong evidence to suggest that the European forest stock is managed very well, and more trees are harvested than are being used. I cannot comment on forestry outside of Europe, or for companies that use non certified forestry. However, all the big mass timber players use sustainably sourced timber, and majority of it from Europe. Stora Enso itself, is one of the worlds largest private forestry owners, and in regards to Stora Enso forest division, in 2020 we planted over 62 million new trees, and grew 30% more timber than we used. As a company that has relied on forests for now over 700 years (we are 732 years old), looking after and managing the health and capacity of our forest's are of course key priorities for us.

I didn't hear anything in this video that said CLT was more "amazing" than concrete. What I did hear was that it is about 50% less polluting to make. I imagine there will always be a need for concrete unless something new is invented to take its place, which this doesn't. This is a material that can be used instead, in some instances, which is much "greener". We should always be searching for more sustainable materials to use in all facets of life as most of the planet's resources are finite.

@gaz6351684
@gaz6351684 6 жыл бұрын
Hi Omer, in regards to moisture protection, DPC and DPM's are used at CLT to concrete ground level to protect the timber from ground water, and an external membrane is used on the exterior of the structure. So, through standard architectural detailing and water protection the CLT should be protected from water ingress. For any rare circumstances like internal water leaks, or for instance during the construction before the protection is applied, the timber can get wet, but when the leak is fixed or the build is watertight, the timber will then dry back out to its natural moisture content of around 15%. One of the great benefits of CLT is that it can be constructed in the wet, snow and bad weather, so temporary wetness is no problem, but for the finished build it should be detailed and protected sufficiently to local building regulations.

comparing embodied energy of concrete, steel, and CLT isn't that helpful in selecting a material. each of these materials has their advantages, disadvantages, and purposes. it's a subtle point, but in comparing the 3 materials, the insinuation is that CLT is the way forward compared to using these "bad" unsustainable materials. rather, all 3 are useful and valuable, it's knowing where and how to use them to their best advantage.
