- 22/09/2020 - Everyone at iWood would like to thank you for your continued support during the pandemic.
As more of our customers have started coming back to work we have seen an influx of orders.
As such we are currently working to a lead time of 14-28 working days
(some products have longer lead times as described in their individual descriptions). We are still following government guidelines to keep our staff and customers safe.
Usually we supply all of our timber untreated ready for you to apply a finish so that you get the end result you require. Recently however, we have started to provide treated timber cladding like our charred and painted black options.
The newest of our treated products is Thermowood cladding which has been treated in a very special way. Not only has it been painted and sealed to stop moisture from getting in, the timber has also been dried in a kiln until there is almost no moisture left in the timber at all, which makes it exceptionally stable.
There is no tree sap left in the wood, so the risk of rotting is reduced, and the boards chosen for the process only contain sound knots. The timbers used are Scandinavian Pine/Spruce and they are durable and stable cladding options.
Advantages of Thermowood Cladding
There are many reasons to use this timber and the 10 year maintenance free period is just one of them.
The low moisture content in the wood (roughly 4-7%) and the sealant used means that the timber will retain its shape much better than untreated timber.
As the wood is dried Resin is removed, so even when the timber is subjected to high temperatures the wood won’t secrete resin.
Thermowood works well in a number of environments and works well in changeable conditions that affect the air temperature and humidity.
The timber is dried using heat and steam, and no chemicals are used in the Thermo process. The only chemicals used are in the treatment that’s applied.
When tested the timber has shown to have a reduced thermal conductivity level by around 20-25% compared to other untreated softwoods.
Sustainability and Installation
The timber is harvested from sustainable, well managed, forests in order to help protect the environment.
The cladding is supplied ready to install through the secret nailing mechanism and can be applied to the building either vertically or horizontally. Fix the boards to softwood battens and use a breathable membrane behind to help the wood breath.
