Re: Price Per Square For Roofing For New Construction. Roofing and plumbing are the 2 areas I typically under-guess on the remodels I take on. Roofing is always a concern from a quality and safety perspective of the sub (i.e. they need to have liability & work comp insurance).
Some newer fire blankets like the Titan21 are made from 100 percent cotton and treated with a nontoxic and biodegradable fire inhibitor instead of potentially harmful flame retardants.
Fire brick is made from a special type of clay. This clay is very pure and uniform and is able to withstand the high temperatures of fireplaces, boilers, and similar constructions. Fire bricks are generally huger than other structural bricks and are often hand molded.
