    I have a kingspan nilvent timber wall and roofing breather membrane. I was thinking of putting the 18mm osb boards on the 2x6 rafters of my single slope roof first then the membrane. I will be using felt nails and felt adhesive for the felt. Can I put felt on top of the kingspan breather membrane? TIA :)

    It's mainly foelr the water proofing as if the felt fails in anyway the membrane is 100% waterproof
