CLT SUPPLIER KLH SAYS: • 1 m3
. (The CO2
of CLT panels will
remove approximately 0.8 tonnes of CO2
the timber). Therefore, 1 m3
is absorbed by of
panels will have approximately 240-250 kg of ‘locked-in’ carbon • All timber produced by KLH is certified by the Programme for the Endorsement of Forest Certifica- tion, which promotes sustainable forest management • The adhesive used in the cross-lamination process is completely solvent and formaldehyde free
• Sawdust and shavings produced in timber processing are reconstituted into biomass pellets and used to heat/power the factory • Speed of construction using CLT provides time savings on building projects • CLT panels are processed using CAD/CAM technology and state- of-the-art computer-controlled panel-cutting machines

draw up fire regulations, understand how and when it will fail much better than steel and concrete. Of course, Paris is already 70 per cent wood behind the stone facade on the boulevard. The fire brigade is perfectly comfortable with engineered timber because there's the reassurance of its controllable behaviour in fire.”
He says timber buildings twice the height of the Opalia office development are already underway in other parts of Europe and while he says statistics on their height are “great for headlines,” he believes modern timber structures are important for another reason. “If there’s one urgent issue we have to deal with and which the construction sector can make a contribution to, it is getting more wood into the buildings because we need to reduce the carbon footprint of the industry, which is huge. The ease of con- crete has put us to sleep, but when you look
at how much energy is required to make it and then demolish at the end of its life it’s ridiculous not to look at wood.
“This is our first wooden building but we now have others in Nantes and in Bordeaux, and we're also doing work on different ways to use CLT – research which we're going to publish.”
In support of wood
Ware concludes: “You still have to convince people because the biggest perceived barrier is cost but now companies like ours know how to tackle that. The answer is an overall cost strategy – not just what timber costs compared to steel. When you look at how much you’re spending on foundations for steel and concrete and how much your building will weigh you start to see figures that are in favour of wood.”
