Insulating return pipe steam heat
there is about 15 feet of supply and return pipe for our steam heat system that runs through our unconditioned garage. Out energy auditor recommended insulating these. I insulated the supply pipes using the 3-foot fiberglass tubes with the white paper wrap and adhesive tape included. I was hoping to insulate the return pipes in a way that saves some money and maybe repurposes some materials I have so that I bring less new crap into the world.
Any creative ideas? I have a bunch of that reflective bubble wrap lying around that I could make as an outer shell around some fluffier insulating material around the pipe. I have some good tape I could use too.
