Behind (above) the heat shield there are square pieces (about 1” square) of insulation to space the insulation off the floor. These will probably be stuck to the floor. Due to the studs one cannot persuade the heat shield from above, but prising next to each removed nut should remove the sheet.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>The heat shield is indeed asbestos. I have just today got rid of my old heat shield in the UK by taking it to the Council tip, at zero cost.
