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.
The first is a high performance ceramic blanket and the second is still air space. The ceramic blanket is held securely in place, eliminating hotspots common with loose fill insulations. In the event of a chimney fire the compressible blanket actually expands with the chimney to accommodate the increased heat load.
