“Pope Douglas has used Demo Plus for roughly ten years now. They have basically replaced all the refractory in all three of our Garbage incinerators and boilers. Demo Plus is very knowledgeable when it comes to what refractory will work best for different applications. Demo Plus has helped our company out in some emergency situations over the years. Demo Plus has also done numerous insulation jobs for us over the years. Anything from covering steam pipes to covering full pieces of equipment. They do a fantastic job  I would highly recommend Demo Plus for your Refractory and insulation needs. I plan on using them for many more years to come.”
