    Probably a silly question...BUT

    Just recieved the duralay heatflow underlay for wet underfloor heating....... problem is no fitting instructions?

    the underlay has a white plastic side and a black felt side. Can/does anybody now which way is the proper way-up to lay on the concrete screed.
