Thanks I may use the SOLITEX FRONTA QUATTRO FB membrane if we are concerned about fire. The main insulation is woodfibre. Given you have to vent timber cladding what are the other options, My OP was realky about the detail at the plinth with the stone.

Hi We are begining our extension to a grade 2 listed building and on the front eleveation the conservation officer has request a stone (to match existing) plinth approx 300mm high with vertical board on board cladding above. We want the cladding to be roughley in line with the plinth and finish dowen on to it I was thinking the membrane. Does anyone see any issues with the attached section? on all other sides the plinth is not rquired so we will render the xps plinth insulaton. Do we need the void behind the stone? or can the stone be up against the plinth insulation? like an insulated cavity? (this would be my prefered way) We are keen not to have the stone forward of cladding as it will have 180 degree outward opening door shutters that we dont want to snag on the stone. although not drawn, there will be periscope ventilltion through to the stone plinth for block and beam and rodent/insect mesh installed behind cladding. Thanks for any comments. wall sections.pdf
