Hi Kelly,

Just out of curiosity, what are the challenges with calcium silicate? When I saw Jerry's photo of the boiler lagging, that's what it looked like they were using. I have seen that type of material used at several operations in the last few years. I do see a lot of whitish material on the floor in Jerry's picture. Does the stuff crumble and fall apart easily?
