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.
Oxygen can even make some materials burn that are not normally flammable. For example, Nomex, which is the material used to make the fireproof clothing firefighters wear, can be lit on fire in an oxygen-rich environment, explains the Massachusetts Executive Office of Public Safety and Security.
