Welding Blankets work really well. They are
not like the radiation shields that they put on you at the dentist.
They actually don't feel much different than a cheap blanket on a bed. The one I have below is called the "Velvet Shield" and you can order it from many different places -- just Google it. You can easily cut it with a pair of scissors to fit just like you want it -- one member on here even fastened it to the floor inside the door so that it "rolls out" over the pipes when you open the door.
