Hi All,

Am building soon using the Sto Poren system (plaster cladding over 50mm AAC panels on 140mm framing) and was wondering if someone who's built with this previously can confirm whether these systems need painting?  The Sto website seems a bit vague, in that the final coat of render can be tinted, but it also mentions painting as well.

Would also be curious to know how others have found the performance of AAC - with the thicker framing and R4.0 batts this allows, I'm hoping for really good thermal and acoustic performance.
