What's the general opinion on what sort of supplier to use for timber? I'm not after anything fancy: I plan to line my garage with battening, insulate between the battens and cover with sheeting, but should I be looking at "proper" timber yards, builders' suppliers like Jewson and Travis Perkins, the big DIY stores, or what? In the past I've had good and bad wood from a multitude of sources: at least in Wickes, say, I could select the wood myself and reject anything that's twisted. Is there a particular type or grade of timber I should use?
I'm in SE Kent (nearest town, Hythe). Can anyone recommend a good source for my area? Or even wider afield if the quality could be guaranteed.
Many thanks.
