Blue dow 4" rigid sm insulation about 450 sheets 2'x8'. Used about 4 years old. $40 a sheet but if you take the whole lot we can discuss a lower price. Cash only I am in Victoria, but delivery is possible for a fee as I have a 20 ft flat deck trailer Update sept 20th: I have 57 sheets left. If the ad is still up I still have them Lowballers, please don't waste your time. This is about half the price of new
