I have tar paper under the original siding already and I was told by one contractor that I could just put vinyl siding right over top but another contractor told me I needed to take the aluminum siding off and start all over again, so which is it?
I would take it all down and put up that Tyvek insulation all over before replacing with vinylYou can get a ton of money for your old siding at the scrap yard.

I am doing a lab on finding the density of aluminum and iron metalsIn my individual calculation the density for Aluminum was 2.88 and Iron was 8For the class average the density of Aluminum was 2.9 and Iron was 7.4Now we have to calculate the Percent Error by doing: |Accepted Value -.
(actual yield - theoretical yield) - X 100 percent error theoretical yield
