Our office team will be available by email for all inquiries including quotes and order confirmations due to the COVID 19 interruptions. Be safe, take care and be kind to one another.


ThermaDura is running high stock levels to ensure a production without interruptions for at least 6 months up to 12 months taking the maximum factory output into account. All ThermaDura stock is owned by ThermaDura as stock self suffiency has always been the insurance for an efficient production and timely delivery. ThermaDura is immediately ready to continue production  when the lockdown ends.


Our new SCM CNC foursider will enable ThermaDura to machine all timber profiles with one pass through the machine. The machine is sitting at the wharf and will be installed after the Covid 19 interruption.
