Has anybody any experience of a product called Thermowood by Finnforest, in particular whether it needs staining, I have spoken to their technical department who weren't particulary helpfull (worrying) saying it's up to you and we don't specify or recommend any products, also said it doesn't need to be but couldn't provide any pics of installations a few years old. I know what to expect with Cedar boarding but this is unknown to me. Reason for asking is that I have a client who wants to use on a 12 storey new build, I'd hate to see a scaffold going up every 5 years or so!

Capital cost!
